Forgiveness

From Wikipedia, the free encyclopedia

Emperor Marcus Aurelius shows clemency to the vanquished after his success against tribes. (Capitoline Museum in Rome)

Forgiveness is the intentional and voluntary process by which a victim undergoes a change in feelings and attitude regarding an offense, and overcomes negative emotions such as resentment and vengeance (however justified it might be). Theorists differ, however, in the extent to which they believe forgiveness also implies replacing the negative emotions with positive attitudes (i.e. an increased ability to wish the offender well). Forgiveness is different from condoning (failing to see the action as wrong and in need of forgiveness), excusing (not holding the offender as responsible for the action), forgetting (removing awareness of the offense from consciousness), pardoning (granted for an acknowledged offense by a representative of society, such as a judge), and reconciliation (restoration of a relationship).

In certain contexts, forgiveness is a legal term for absolving or giving up all claims on account of debt, loan, obligation, or other claims.

As a psychological concept and virtue, the benefits of forgiveness have been explored in religious thought, social sciences and medicine. Forgiveness may be considered simply in terms of the person who forgives including forgiving themself, in terms of the person forgiven or in terms of the relationship between the forgiver and the person forgiven. In most contexts, forgiveness is granted without any expectation of restorative justice, and without any response on the part of the offender (for example, one may forgive a person who is incommunicado or dead). In practical terms, it may be necessary for the offender to offer some form of acknowledgment, an apology, or even just ask for forgiveness, in order for the wronged person to believe themselves able to forgive as well.

Social and political dimensions of forgiveness involves the strictly private and religious sphere of "forgiveness". The notion of "forgiveness" is generally considered unusual in the political field. However, Hannah Arendt considers that the "faculty of forgiveness" has its place in public affairs. The philosopher believes that forgiveness can liberate resources both individually and collectively in the face of the irreparable. During an investigation in Rwanda on the discourses and practices of forgiveness after the 1994 genocide, sociologist Benoit Guillou illustrated the extreme polysemy (multiple meanings) of the word "forgiveness" but also the eminently political character of the notion. By way of conclusion of his work, the author proposes four main figures of forgiveness to better understanding, on the one hand, ambiguous uses and, on the other hand, the conditions under which forgiveness can mediate a resumption of social link.

Most world religions include teachings on the nature of forgiveness, and many of these teachings provide an underlying basis for many varying modern day traditions and practices of forgiveness. Some religious doctrines or philosophies place greater emphasis on the need for humans to find some sort of divine forgiveness for their own shortcomings, others place greater emphasis on the need for humans to practice forgiveness of one another, yet others make little or no distinction between human and divine forgiveness.

The term forgiveness can be used interchangeably and is interpreted many different ways by people and cultures. This is specifically important in relational communication because forgiveness is a key component in communication and the overall progression as an individual and couple or group. When all parties have a mutual viewing for forgiveness then a relationship can be maintained. "Understanding antecedents of forgiveness, exploring the physiology of forgiveness, and training people to become more forgiving all imply that we have a shared meaning for the term".

Research

Factors determining the likelihood of forgiveness in an intimate relationship

Although there is presently no consensus for a psychological definition of forgiveness in research literature, agreement has emerged that forgiveness is a process, and a number of models describing the process of forgiveness have been published, including one from a radical behavioral perspective.

Dr. Robert Enright from the University of Wisconsin–Madison founded the International Forgiveness Institute and is considered the initiator of forgiveness studies. He developed a 20-Step Process Model of Forgiveness. Recent work has focused on what kind of person is more likely to be forgiving. A longitudinal study showed that people who were generally more neurotic, angry, and hostile in life were less likely to forgive another person even after a long time had passed. Specifically, these people were more likely to still avoid their transgressor and want to enact revenge upon them two and a half years after the transgression.

Studies show that people who forgive are happier and healthier than those who hold resentments. The first study to look at how forgiveness improves physical health discovered that when people think about forgiving an offender it leads to improved functioning in their cardiovascular and nervous systems. Another study at the University of Wisconsin found the more forgiving people were, the less they suffered from a wide range of illnesses. The less forgiving people reported a greater number of health problems.

The research of Dr. Fred Luskin of Stanford University, and author of the book Forgive for Good presented evidence that forgiveness can be learned (i.e. can be a teachable skill, with practice) based on research projects into the effects of teaching forgiveness: giving empirical validity to the concept that forgiveness is powerful as well as excellent for your health. In three separate studies, including one with Catholics and Protestants from Northern Ireland whose family members were murdered in the political violence, he found that people who are taught how to forgive become less angry, feel less hurt, are more optimistic, become more forgiving in a variety of situations, and become more compassionate and self-confident. His studies show a reduction in experience of stress, physical manifestations of stress, and an increase in vitality.

Ideas about what forgiveness is not

  • Forgiveness is not condoning.
  • Forgiveness is not forgetting.
  • Forgiveness is not excusing (i.e. making reasons to explain away offender's responsibility or free-will).
  • Forgiveness doesn't have to be religious or 'otherworldly'.
  • Forgiveness is not minimizing your hurt.
  • Forgiveness is not reconciliation (i.e. reestablishing trust in the relationship).
  • Forgiveness is not denying or suppressing anger (rather its focus is on resentment).—In particular, in order to forgive it is healthy to acknowledge and express negative emotions, before you can even forgive.
  • Forgiveness is not ignoring accountability or justice.—In particular, punishment and recompensation are independent of the choice to forgive (you can forgive, or not forgive, and still pursue punishment and/or recompensation, regardless).
  • Forgiveness is not pardoning: It cannot be granted, or chosen, by someone else.
  • Emotional forgiveness is not the same as decisional forgiveness (or the expression of forgiveness): expressing emotions (i.e., 'I am angry at you' or 'I forgive you') is not the same as genuinely having or experiencing the emotions (i.e., people can deny, mistake, or lie about their emotional experience to another person while genuinely feeling something else instead).
  • Emotional forgiveness is not the same as decisional forgiveness (or the expression of forgiveness): expressing emotions (i.e., 'I am angry at you' or 'I forgive you') is not the same as genuinely having or experiencing the emotions (i.e., people can deny, mistake, or lie about their emotional experience to another person while genuinely feeling something else instead).
  • Although, heavily debated, emotional forgiveness is for you, not the offender (i.e., unless you choose to make it so: by expressing it, or by trying to reconcile).

The timeliness of forgiveness

The psychologist Wanda Malcolm writes a chapter in Women's Reflections on the Complexities of Forgiveness titled "the Timeliness of Forgiveness Interventions" where she outlines reasons why forgiveness takes time: when work on self (care/healing) takes priority (i.e. therapy, medical injuries, etc.), when issues of relational safety need to be addressed, and where facilitating forgiveness may be premature immediately after an interpersonal offense. Malcolm explains that "premature efforts to facilitate forgiveness may be a sign of our reluctance to witness our client’s pain and suffering and may unwittingly reinforce the client’s belief that the pain and suffering is too much to bear and must be suppressed or avoided."

Worthington (et al.) observed that “anything done to promote forgiveness has little impact unless substantial time is spent at helping participants think through and emotionally experience their forgiveness”. Efforts to facilitate forgiveness may be premature immediately after an interpersonal injury, if not harmful.

Religious views

World Religions
World Religions

Religion can have an impact on how someone chooses to forgive and the process they go through. Most have conceptualized religion's effect in three ways—through religious activity, religious affiliation and teachings, and imitation. There are several thousand religions in the world and each one can look at forgiveness a different way.

Abrahamic

Judaism

In Judaism, if a person causes harm, but then sincerely and honestly apologizes to the wronged individual and tries to rectify the wrong, the wronged individual is encouraged, but not required, to grant forgiveness:
  • "It is forbidden to be obdurate and not allow yourself to be appeased. On the contrary, one should be easily pacified and find it difficult to become angry. When asked by an offender for forgiveness, one should forgive with a sincere mind and a willing spirit ... forgiveness is natural to the seed of Israel." (Mishneh Torah, Teshuvah 2:10)
In Judaism, one must go "to those he has harmed" in order to be entitled to forgiveness. [One who sincerely apologizes three times for a wrong committed against another has fulfilled their obligation to seek forgiveness. (Shulchan Aruch) OC 606:1] This means that in Judaism a person cannot obtain forgiveness from God for wrongs the person has done to other people. This also means that, unless the victim forgave the perpetrator before he died, murder is unforgivable in Judaism, and they will answer to God for it, though the victims' family and friends can forgive the murderer for the grief they caused them. The Tefila Zaka meditation, which is recited just before Yom Kippur, closes with the following:
  • "I know that there is no one so righteous that they have not wronged another, financially or physically, through deed or speech. This pains my heart within me, because wrongs between humans and their fellow are not atoned by Yom Kippur, until the wronged one is appeased. Because of this, my heart breaks within me, and my bones tremble; for even the day of death does not atone for such sins. Therefore I prostrate and beg before You, to have mercy on me, and grant me grace, compassion, and mercy in Your eyes and in the eyes of all people. For behold, I forgive with a final and resolved forgiveness anyone who has wronged me, whether in person or property, even if they slandered me, or spread falsehoods against me. So I release anyone who has injured me either in person or in property, or has committed any manner of sin that one may commit against another [except for legally enforceable business obligations, and except for someone who has deliberately harmed me with the thought ‘I can harm him because he will forgive me']. Except for these two, I fully and finally forgive everyone; may no one be punished because of me. And just as I forgive everyone, so may You grant me grace in the eyes of others, that they too forgive me absolutely."
Thus the "reward" for forgiving others is not God's forgiveness for wrongs done to others, but rather help in obtaining forgiveness from the other person.

Sir Jonathan Sacks, chief rabbi of the United Hebrew Congregations of the Commonwealth, summarized: "it is not that God forgives, while human beings do not. To the contrary, we believe that just as only God can forgive sins against God, so only human beings can forgive sins against human beings."

Jews observe a Day of Atonement Yom Kippur on the day before God makes decisions regarding what will happen during the coming year. Just prior to Yom Kippur, Jews will ask forgiveness of those they have wronged during the prior year (if they have not already done so). During Yom Kippur itself, Jews fast and pray for God's forgiveness for the transgressions they have made against God in the prior year. Sincere repentance is required, and once again, God can only forgive one for the sins one has committed against God; this is why it is necessary for Jews also to seek the forgiveness of those people who they have wronged.

Christianity

Rembrandt – "The Return of the Prodigal Son
 
Forgiveness is central to Christian ethics and is a frequent topic in sermons and theological works, because Christianity is about Christ, Christ is about redemption, and redemption is about forgiveness of sin.
God's forgiveness
Unlike in Judaism, God can forgive sins committed by people against people, since he can forgive every sin except for the eternal sin, and forgiveness from one's victim is not necessary for salvation. The Parable of the Prodigal Son is perhaps the best known parable about forgiveness and refers to God's forgiveness for those who repent. Jesus asked for God's forgiveness of those who crucified him. "And Jesus said, 'Father, forgive them, for they know not what they do.'" – Luke 23:34
Forgiving others
Forgiving offenses is among the spiritual works of mercy, and forgiving others begets being forgiven by God. Considering Mark 11:25, and Matthew 6:14–15, that follows the Lord's Prayer, "For if you forgive men when they sin against you, your heavenly Father will also forgive you. But if you do not forgive men their sins, your Father will not forgive your sins," forgiveness is not an option to a Christian, rather one must forgive to be a Christian. Forgiveness in Christianity is a manifestation of submission to Christ and fellow believers.

In the New Testament, Jesus speaks of the importance of forgiving or showing mercy toward others. This is based on the belief that God forgives sins through faith in the atoning sacrifice of Jesus Christ in his death (1 John 2:2) and that, therefore, Christians should forgive others (Ephesians 4:32). Jesus used the parable of the unmerciful servant (Matthew 18:21–35) to show that His followers (represented in the parable by the servant) should forgive because God (represented by the king) forgives much more. 

In the Sermon on the Mount, Jesus repeatedly spoke of forgiveness: "Blessed are the merciful, for they will be shown mercy." Matthew 5:7 (NIV) "Therefore, if you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there in front of the altar. First go and be reconciled to your brother; then come and offer your gift." Matthew 5:23–24 (NIV) "And when you stand praying, if you hold anything against anyone, forgive him, so that your Father in heaven may forgive you your sins." Mark 11:25 (NIV) "But I tell you who hear me: Love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you. If someone strikes you on one cheek, turn to him the other also." Luke 6:27–29 (NIV) "Be merciful, just as your Father is merciful." Luke 6:36 (NIV) "Do not judge, and you will not be judged. Do not condemn, and you will not be condemned. Forgive, and you will be forgiven." Luke 6:37 (NIV)

Elsewhere, it is said "Then Peter came to Him and said, "Lord, how often shall my brother sin against me, and I forgive him? Up to seven times?" Jesus said to him, "I do not say to you, up to seven times, but up to seventy times seven." Matthew 18:21–22 (NKJV)

Benedict XVI, on a visit to Lebanon in 2012, insisted that peace must be based on mutual forgiveness: "Only forgiveness, given and received, can lay lasting foundations for reconciliation and universal peace".

Pope Francis during a General Audience explained forgiving others as God forgives oneself.

Islam

Islam teaches that Allah is Al-Ghaffur "The Oft-Forgiving", and is the original source of all forgiveness (ghufran غفران). Seeking forgiveness from Allah with repentance is a virtue.
(...) Allah forgives what is past: for repetition Allah will exact from him the penalty. For Allah is Exalted, and Lord of Retribution.
— Quran 5:95
Islam recommends forgiveness, because Allah values forgiveness. There are numerous verses in Quran and the Hadiths recommending forgiveness. However, Islam also allows revenge to the extent harm done, but forgiveness is encouraged, with a promise of reward from Allah.
The recompense for an injury is an injury equal thereto (in degree): but if a person forgives and makes reconciliation, his reward is due from Allah: for (Allah) loveth not those who do wrong.
— Quran 42:40
Afw (عفو is another term for forgiveness in Islam; it occurs 35 times in Quran, and in some Islamic theological studies, it is used interchangeably with ghufran. Afw means to pardon, to excuse for a fault or an offense. According to Muhammad Amanullah, forgiveness ('Afw) in Islam is derived from three wisdoms. First and the most important wisdom of forgiveness is that it is merciful when the victim or guardian of the victim accepts money instead of revenge. The second wisdom of forgiveness is that it increases honor and prestige of the one who forgives. Forgiveness is not a sign of weakness, humiliation or dishonor. Forgiveness is honor, raises the merit of the forgiver in the eyes of Allah, and enables a forgiver to enter paradise. The third wisdom of forgiveness is that according to some scholars, such as al-Tabari and al-Qurtubi, forgiveness expiates (kaffarah) the forgiver from the sins they may have committed at other occasions in life. Forgiveness is a form of charity (sadaqat). Forgiveness comes from taqwa (piety), a quality of God-fearing people.

Bahá'í Faith

In the Bahá'í Writings, this explanation is given of how to be forgiving individuals toward others:
"Love the creatures for the sake of God and not for themselves. You will never become angry or impatient if you love them for the sake of God. Humanity is not perfect. There are imperfections in every human being, and you will always become unhappy if you look toward the people themselves. But if you look toward God, you will love them and be kind to them, for the world of God is the world of perfection and complete mercy. Therefore, do not look at the shortcomings of anybody; see with the sight of forgiveness."
`Abdu'l-Bahá, The Promulgation of Universal Peace, p. 92

Buddhism

In Buddhism, forgiveness is seen as a practice to prevent harmful thoughts from causing havoc on one's mental well-being. Buddhism recognizes that feelings of hatred and ill-will leave a lasting effect on our mind karma. Instead, Buddhism encourages the cultivation of thoughts that leave a wholesome effect. "In contemplating the law of karma, we realize that it is not a matter of seeking revenge but of practicing mettā and forgiveness, for the victimizer is, truly, the most unfortunate of all." When resentments have already arisen, the Buddhist view is to calmly proceed to release them by going back to their roots. Buddhism centers on release from delusion and suffering through meditation and receiving insight into the nature of reality. Buddhism questions the reality of the passions that make forgiveness necessary as well as the reality of the objects of those passions. "If we haven’t forgiven, we keep creating an identity around our pain, and that is what is reborn. That is what suffers."

Buddhism places much emphasis on the concepts of Mettā (loving kindness), karuna (compassion), mudita (sympathetic joy), and upekkhā (equanimity), as a means to avoiding resentments in the first place. These reflections are used to understand the context of suffering in the world, both our own and the suffering of others.
"He abused me, he struck me, he overcame me, he robbed me’ — in those who harbor such thoughts hatred will never cease."
"He abused me, he struck me, he overcame me, he robbed me’ — in those who do not harbor such thoughts hatred will cease."
(Dhammapada 1.3–4;)

Hindu Dharma

Holi is the Hindu festival of colors, celebrated in spring. The young and the old celebrate by dancing, laughing and smearing each other with Abir – coloured powder, or spraying Gulal – colored water. Traditionally, this is also a day to mark forgiveness, meet others and make up one's ruptured relationships (if). In Indonesia, among Balinese Hindus, Ngembak Geni - the day after Nyepi – is the ritual festive day in spring to meet, and both seek forgiveness and forgive each other.
 
In Vedic literature and epics of Hinduism, Ksama or Kshyama (Sanskrit: क्षमा) and fusion words based on it, describe the concept of forgiveness. The word ksama is often combined with kripa (tenderness), daya (kindness) and karuna (करुणा, compassion) in Sanskrit texts. In Rg Veda, forgiveness is discussed in verses dedicated to deity Varuna, both the context of the one who has done wrong and one who is wronged. Forgiveness is considered one of the six cardinal virtues in Hindu Dharma.

The theological basis for forgiveness in Hindu Dharma is that a person who does not forgive carries a baggage of memories of the wrong, of negative feelings, of anger and unresolved emotions that affect their present as well as future. In Hindu Dharma, not only should one forgive others, but one must also seek forgiveness if one has wronged someone else. Forgiveness is to be sought from the individual wronged, as well as society at large, by acts of charity, purification, fasting, rituals and meditative introspection.

The concept of forgiveness is further refined in Hindu Dharma by rhetorically contrasting it in feminine and masculine form. In feminine form, one form of forgiveness is explained through Lakshmi (called Goddess Sri in some parts of India); the other form is explained in the masculine form through her husband Vishnu. Feminine Lakshmi forgives even when the one who does wrong does not repent. Masculine Vishnu, on the other hand, forgives only when the wrongdoer repents. In Hindu Dharma, the feminine forgiveness granted without repentance by Lakshmi is higher and more noble than the masculine forgiveness granted only after there is repentance. In the Hindu epic Ramayana, Sita – the wife of King Rama – is symbolically eulogized for forgiving a crow even as it harms her. Later in the epic Ramayana, she is eulogized again for forgiving those who harass her while she has been kidnapped in Lanka. Many other Hindu stories discuss forgiveness with or without repentance.

The concept of forgiveness is treated in extensive debates of Hindu literature. In some Hindu texts, certain sins and intentional acts are debated as naturally unforgivable; for example, murder and rape; these ancient scholars argue whether blanket forgiveness is morally justifiable in every circumstance, and whether forgiveness encourages crime, disrespect, social disorder and people not taking you seriously. Other ancient Hindu texts highlight that forgiveness is not same as reconciliation.

Forgiveness in Hindu Dharma does not necessarily require that one reconcile with the offender, nor does it rule out reconciliation in some situations. Instead forgiveness in Hindu philosophy is being compassionate, tender, kind and letting go of the harm or hurt caused by someone or something else. Forgiveness is essential for one to free oneself from negative thoughts, and being able to focus on blissfully living a moral and ethical life (dharmic life). In the highest self-realized state, forgiveness becomes the essence of one's personality, where the persecuted person remains unaffected, without agitation, without feeling like a victim, free from anger (akrodhi).

Other epics and ancient literature of Hindu Dharma discuss forgiveness. For example:
Forgiveness is virtue; forgiveness is sacrifice; forgiveness is the Vedas; forgiveness is the Shruti.
Forgiveness protecteth the ascetic merit of the future; forgiveness is asceticism; forgiveness is holiness; and by forgiveness is it that the universe is held together.
— Mahabharata, Book 3, Vana Parva, Section XXIX, 
Righteousness is the one highest good, forgiveness is the one supreme peace, knowledge is one supreme contentment, and benevolence, one sole happiness.
— Mahabharata, Book 5, Udyoga Parva, Section XXXIII, 
Janak asked: "Oh lord, how does one attain wisdom? how does liberation happen?"
Ashtavakra replied: "Oh beloved, if you want liberation, then renounce imagined passions as poison, take forgiveness, innocence, compassion, contentment and truth as nectar; (...)"

Jainism

In Jainism, forgiveness is one of the main virtues that needs to be cultivated by the Jains. Kṣamāpanā or supreme forgiveness forms part of one of the ten characteristics of dharma. In the Jain prayer, (pratikramana) Jains repeatedly seek forgiveness from various creatures—even from ekindriyas or single sensed beings like plants and microorganisms that they may have harmed while eating and doing routine activities. Forgiveness is asked by uttering the phrase, Micchāmi dukkaḍaṃ. Micchāmi dukkaḍaṃ is a Prakrit language phrase literally meaning "may all the evil that has been done be fruitless." During samvatsari—the last day of Jain festival paryusana—Jains utter the phrase Micchami Dukkadam after pratikraman. As a matter of ritual, they personally greet their friends and relatives micchāmi dukkaḍaṃ seeking their forgiveness. No private quarrel or dispute may be carried beyond samvatsari, and letters and telephone calls are made to the outstation friends and relatives asking their forgiveness.

Pratikraman also contains the following prayer:
Khāmemi savva-jīve savvë jive khamantu me /
metti me savva-bhūesu, veraṃ mejjha na keṇavi //
(I ask pardon of all creatures, may all creatures pardon me.
May I have friendship with all beings and enmity with none.)
In their daily prayers and samayika, Jains recite Iryavahi sutra seeking forgiveness from all creatures while involved in routine activities:
May you, O Revered One! Voluntarily permit me. I would like to confess my sinful acts committed while walking. I honour your permission. I desire to absolve myself of the sinful acts by confessing them. I seek forgiveness from all those living beings which I may have tortured while walking, coming and going, treading on living organism, seeds, green grass, dew drops, ant hills, moss, live water, live earth, spider web and others. I seek forgiveness from all these living beings, be they — one sensed, two sensed, three sensed, four sensed or five sensed. Which I may have kicked, covered with dust, rubbed with ground, collided with other, turned upside down, tormented, frightened, shifted from one place to another or killed and deprived them of their lives. (By confessing) may I be absolved of all these sins.
Jain texts quote Māhavīra on forgiveness:
By practicing prāyaṣcitta (repentance), a soul gets rid of sins, and commits no transgressions; he who correctly practises prāyaṣcitta gains the road and the reward of the road, he wins the reward of good conduct. By begging forgiveness he obtains happiness of mind; thereby he acquires a kind disposition towards all kinds of living beings; by this kind disposition he obtains purity of character and freedom from fear.
— Māhavīra in Uttarādhyayana Sūtra 29:17–18
Even the code of conduct amongst the monks requires the monks to ask forgiveness for all transgressions:
If among monks or nuns occurs a quarrel or dispute or dissension, the young monk should ask forgiveness of the superior, and the superior of the young monk. They should forgive and ask forgiveness, appease and be appeased, and converse without restraint. For him who is appeased, there will be success (in control); for him who is not appeased, there will be no success; therefore one should appease one's self. 'Why has this been said, Sir? Peace is the essence of monasticism'.
Kalpa Sūtra 8:59

Hoʻoponopono

Hoʻoponopono is an ancient Hawaiian practice of reconciliation and forgiveness, combined with prayer. Similar forgiveness practices were performed on islands throughout the South Pacific, including Samoa, Tahiti and New Zealand. Traditionally Hoʻoponopono is practiced by healing priests or kahuna lapaʻau among family members of a person who is physically ill. Modern versions are performed within the family by a family elder, or by the individual alone.

Popular recognition

The need to forgive is widely recognized by the public, but they are often at a loss for ways to accomplish it. For example, in a large representative sampling of American people on various religious topics in 1988, the Gallup Organization found that 94% said it was important to forgive, but 85% said they needed some outside help to be able to forgive. However, not even regular prayer was found to be effective. 

Akin to forgiveness is mercy, so even if a person is not able to complete the forgiveness process they can still show mercy, especially when so many wrongs are done out of weakness rather than malice. The Gallup poll revealed that the only thing that was effective was "meditative prayer".

Forgiveness as a tool has been extensively used in restorative justice programs, after the abolition of apartheid Truth and Reconciliation Commission (South Africa), run for victims and perpetrators of Rwandan genocide, the violence in Israeli–Palestinian conflict, and Northern Ireland conflict, which has also been documented in film, Beyond Right and Wrong: Stories of Justice and Forgiveness (2012).

Forgiveness theory can be found and applied to religion, relationships, health, individual, interventions, and much more. Forgiveness is an important trait to understand and possess because it is something that everyone has to experience in their both personal and professional life.

Forgiveness is associated with the theory of emotion because it is largely drawn from a person's emotional connection and level with the situation. Forgiveness is something that most people are taught to understand and practice at a young age. Because forgiveness is an emotion there is not an exact originator of it but there are several theorists, psychologists, and sociologists who link it to other theories or apply theories to help understand the concept. The philosopher Joseph Butler (Fifteen Sermons) defined forgiveness as "overcoming of resentment, the overcoming of moral hatred, as a speech act, and as forbearance".

Forgiveness in relationships

Forgiveness in marriage

Forgiveness in marriage is an important aspect in a marriage. When two individuals are able to forgive each other it results in a long happy marriage. Forgiveness can help prevent problems from accruing in the married couple's future.

In a 2005 study, researchers were interested in figuring out whether forgiveness is important in a marriage. When does forgiveness usually accrue? Does it accrue before an argument or after an argument? Does forgiveness take a role when a person breaks a promise? etc. Researcher found six components that were related to forgiveness in marriage and explains how each one relates to forgiveness. The six components are: satisfaction, ambivalence, conflict, attributions, empathy and commitment.

Researchers provided an overview of forgiveness in marriage and how individuals in a relationship believe that if forgiveness accrues then you must forget what had happened. Moreover, based on the interventions and recommendations the researchers started to see how important forgiveness is in a relationship and how it can lead to a happy and healthy relationship.

In a 2005 study, researchers mentioned that when couples forgive their spouses they sometimes need help from professionals to overcome their pain that might be left behind. Researchers also described the difference between how each individual perceives the situation based on who is in pain and who caused the pain. Also how the couple react to the situation based on their feelings and how they personally respond to the situation.

The model of forgiveness:
"Enright's model of forgiveness has received empirical support and sees forgiveness as a journey through four phases" which are:
  1. Uncovering phase: Emphases on exploring the pain that the individual has experienced.
  2. Decision phase: The nature of forgiveness is discussed. Also the individual commits that they will try to forgive the spouse
  3. Work phase: The focus shifts to the transgressor in an effort to gain insight and understanding.
  4. Deepening phase': The victim moves toward resolution, becoming aware that he/she is not alone, having been the recipient of others' forgiveness, and finds meaning and purpose in the forgiveness process.
Furthermore, when married couples argue they tend to focus on who is right and who is wrong. Also couples tend to focus on who proves the other wrong which can cause more problems and can make the problem worse because it will make it harder to forgive one another.

Recommendation and interventions:
The researchers also came up with recommendation for practitioners and intervention to help individuals that are married on how to communicate with each other, how to resolve problems and how to make it easier to forgive each other. Some of the interventions of forgiveness in marriage has been a great success. It encouraged forgiveness and made couples happier together.

Some of the recommendations that was given to practitioners was that the individuals had to explore and understand what forgiveness means before starting any intervention because the preconceived idea of forgiveness can cause problems with couples being open to forgive. For example, an individual not forgiving their spouse out of fear that the spouse might think that they are weak which can cause a conflict. It was stated that the couple must know the following:
  • Forgiveness takes
  • The different forms of forgiveness
  • The danger in communicating in forgiveness
  • That Perpetrators and victims have different perceptive context is important
Furthermore, the researchers thought of ways to further help married couples in the future and suggested that they should explore the following:
  • The importance of seeking forgiveness
  • Self-forgiveness
  • The role of the sacred in marital forgiveness
Relationships are at the sentiment aspect of our lives; with our families at home and friends outside. Relationships interact in schools and universities, with work mates and, with colleagues at the workplace and in our diverse communities. In the article it states, the quality of these relationships determines our individual well-being, how well we learn, develop and function, our sense of connectedness with others and the health so society.

In 2002, two innovators of Positive Psychology, Ed Diener and Martin Seligman, conducted a study at the University of Illinois on the 10% of students with the highest scores recorded on a survey of personal happiness. What they came up with was most salient characteristics shared by students who were very content and showed positive life styles were the ones who "their strong ties to friends and family and commitment to spending time with them."

A study done in 2000, identified as a key study that taken part and examined two natures of relationships (friends and family) and at what age does the support switch importance from one to the other. The study showed that people whom had good family relationship were able to have more positive outside relationships with friends. Through the family relationship and friendships, the character of the individual was built to forgive and learn from the experience in the family.

In 2001, Charlotte vanOyen Witvliet asked people to think about someone who had hurt, wronged, or offended them. As they thought to answer, she observed their reaction. She observed their blood pressure, heart rate, facial muscle tension, and sweat gland activity. To deliberate on an old misdemeanor is to practice unforgiveness. The outcome to the recall of the grudge the candidates’ blood pressure and heart rate increased, and they sweated more. Pondering about their resents was stressful, and subjects found the rumination unpleasant. When they adept forgiveness, their physical stimulation glided downward. They showed no more of an anxiety reaction than normal wakefulness produces.

In 2013, study on self-forgiveness with spouse forgiveness has a better outcome to a healthier life by Pelucchi, Paleari, Regalia and Fincham. This study investigates self-forgiveness for real hurts committed against the partner in a romantic relationship (168 couples). For both males and females, the mistaken partners were more content with their romantic relationship to the extent that they had more positive and less negative sentiment and thoughts toward themselves. In the study when looking at the victimized partners were more gratified with the relationship when the offending partner had less negative sentiment and thoughts towards themselves. It concludes that self-forgiveness when in a relationship has positive impact on both the offending and victimized partner.

Forgiveness interventions

Both negative and positive affect play a role in forgiveness interventions. It is the general consensus across researchers in the field of psychology, that the overarching purpose of forgiveness interventions is to decrease overall negative affect associated with the stimulus and increase the individual's positive affect.

The disease model has been mainly used in regards to therapy, however the incorporation of forgiveness into therapy has been lacking, and has been slowly gaining popularity in the last couple of decades. More recent research has shown how the growth of forgiveness in psychology has given rise to the study of forgiveness interventions.

Different types

There are various forms of forgiveness interventions. One common adaptation used by researchers is where patients are forced to confront the entity preventing them from forgiving by using introspective techniques and expressing this to the therapist. Another popular forgiveness intervention is getting individual to try to see things from the offender's point of view. The end goal for this adaptation is getting the individual to perhaps understand the reasoning behind the offender's actions. If they are able to do this then they might be able to forgive the offender more easily.

There is, however, conflicting evidence on the effectiveness of forgiveness interventions.

Contrary evidence

Although research has taken into account the positive aspects of forgiveness interventions, there are also negative aspects that have been explored as well. Some researchers have taken a critical approach and have been less accepting of the forgiveness intervention approach to therapy.

Critics have argued that forgiveness interventions may actually cause an increase in negative affect because it is trying to inhibit the individual's own personal feelings towards the offender. This can result in the individual feeling negatively towards themself. This approach is categorizing the individual's feelings by implying that the negative emotions the individual is feeling are unacceptable and feelings of forgiveness is the correct and acceptable way to feel. It might inadvertently promote feelings of shame and contrition within the individual.

Wanda Malcolm, a registered psychologist, states: "that it is not a good idea to make forgiveness an a-priori goal of therapy". Steven Stosny, also adds, that you heal first then forgive (NOT forgive then heal); that fully acknowledging the grievance (both what actions were harmful, and naming the emotions the victim felt as a response to the offenders actions) is an essential first step, before forgiveness can occur.

Some researchers also worry that forgiveness interventions will promote unhealthy relationships. They worry that individuals with toxic relationships will continue to forgive those who continuously commit wrong acts towards them when in fact they should be distancing themselves from these sorts of people.

A number of studies showcase high effectiveness rates of forgiveness interventions when done continuously over a long period of time. Some researchers have found that these interventions have been proven ineffective when done over short spans of time.

Forgiveness interventions: children

There has been some research within the last decade outlining some studies that have looked at the effectiveness of forgiveness interventions on young children. There have also been several studies done studying this cross culturally. One study that explored this relationship, was a study conducted in 2009 by Eadaoin Hui and Tat Sing Chau. In this study, Hui and Chau looked at the relationship between forgiveness interventions and Chinese children who were less likely to forgive those who had wronged them. The findings of this study showed that there was an effect of forgiveness interventions on the young Chinese children.

Forgiveness and mental health

Survey data from 2000 showed that 61% of participants that were part of a small religious group reported that the group helped them be more forgiving. Individuals reported that their religion groups which promote forgiveness was related to self-reports of success in overcoming addictions, guilt, and perceiving encouragement when feeling discouraged.

It is suggested that mindfulness plays a role in forgiveness and health. The forgiveness of others has a positive effect on physical health when it is combined with mindfulness but evidence shows that forgiveness only effects health as a function of mindfulness.

A study from 2005 states that self-forgiveness is an important part of self-acceptance and mental health in later life. The inability to self-forgive can compromise mental health. For some elderly people, self-forgiveness requires reflecting on a transgression to avoid repeating wrongdoings, individuals seek to learn from these transgressions in order to improve their real self-schemas. When individuals are successful at learning from these transgressions, they may experience improved mental health.

A study in 2015 looks at how self-forgiveness can reduce feelings of guilt and shame associated with hypersexual behavior. Hypersexual behaviour can have negative effects on individuals by causing distress and life problems. Self-forgiveness may be a component that can help individuals reduce hypersexual negative behaviours that cause problems.

Evidence shows that self-forgiveness and procrastination may be associated; self-forgiveness allows the individual to overcome the negatives associated with an earlier behaviour and engage in approach-oriented behaviours on a similar task. Learning to forgive oneself for procrastination can be positive because it can promote self-worth and may cause positive mental health. Self-forgiveness for procrastination may also reduce procrastination.

Forgiveness and physical health

Physical Fitness

The correlation between forgiveness and physical health is a concept that has recently gained traction in research. Some studies claim that there is no correlation, either positive or negative between forgiveness and physical health, and others show a positive correlation.

Evidence supporting a correlation

Individuals with forgiveness as a personality trait have been shown to have overall better physical health. In a study on relationships, regardless if someone was in a negative or positive relationship, their physical health seemed to be influenced at least partially by their level of forgiveness.

Individuals who make a decision to genuinely forgive someone are also shown to have better physical health. This is due to the relationship between forgiveness and stress reduction. Forgiveness is seen as preventing poor physical health and managing good physical health.

Specifically individuals who choose to forgive another after a transgression have lower blood pressure and lower cortisol levels than those who do not. This is theorized to be due to various direct and indirect influences of forgiveness, which point to forgiveness as an evolutionary trait. See Broaden and Build Theory.

Direct influences include: Reducing hostility (which is inversely correlated with physical health), and the concept that unforgiveness may reduce the immune system because it puts stress on the individual. Indirect influences are more related to forgiveness as a personality trait and include: forgiving people may have more social support and less stressful marriages, and forgiveness may be related to personality traits that are correlated with physical health.

Forgiveness may also be correlated with physical health because hostility is associated with poor coronary performance. Unforgiveness is as an act of hostility, and forgiveness as an act of letting go of hostility. Heart patients who are treated with therapy that includes forgiveness to reduce hostility have improved cardiac health compared to those who are treated with medicine alone.

Forgiveness may also lead to better perceived physical health. This correlation applies to both self-forgiveness and other-forgiveness but is especially true of self-forgiveness. Individuals who are more capable of forgiving themselves have better perceived physical health.

Criticisms

Forgiveness studies have been refuted by critics who claim that there is no direct correlation between forgiveness and physical health. Forgiveness, due to the reduction of directed anger, contributes to mental health and mental health contributes to physical health, but there is no evidence that forgiveness directly improves physical health. Most of the studies on forgiveness cannot isolate it as an independent variable in an individual's well-being, so it is difficult to prove causation. Further studies imply that while there is not enough research to directly relate forgiveness to physical health there are factors that can be implied. This relates more to physiological measures and what happens to a body during the stages of forgiveness in their daily life.

Additionally, research into the correlation between physical health and forgiveness has been criticized for being too focused on unforgiveness. Research shows more about what hostility and unforgiveness contribute to poor health than it shows what forgiveness contributes to physical health. Additionally, research notes that unforgiving or holding grudges can contribute to adverse health outcomes by perpetuating anger and heightening SNS arousal and cardiovascular reactivity. Expression of anger has been strongly associated with chronically elevated blood pressure and with the aggregation of platelets, which may increase vulnerability for heart disease.

Self-forgiveness

Self-Forgiveness

Self-forgiveness happens in situations where an individual has done something that they perceive to be morally wrong and they consider themselves to be responsible for the wrongdoing. Self-forgiveness is the overcoming of negative emotions that the wrongdoer associates with the wrongful action. Negative emotions associated with wrongful action can include guilt, regret, remorse, blame, shame, self-hatred and/or self-contempt.

Major life events that include trauma can cause individuals to experience feelings of guilt or self-hatred. Humans have the ability to reflect on their behaviours to determine if their actions are moral. In situations of trauma, humans can choose to self-forgive by allowing themselves to change and live a moral life. Self-forgiveness may be required in situations where the individual hurt themselves or in situations where they hurt others. Indeed, self-forgiveness has been shown to have a moderating effect between depression and suicidality: suggesting self-forgiveness (up-to a point) as not only a protective factor of suicide, but also hinting at possible prevention strategies.

Therapeutic model

Individuals can unintentionally cause harm or offence to one another in everyday life. It is important for individuals to be able to recognize when this happens, and in the process of making amends, have the ability to self-forgive. Specific research suggests that the ability to genuinely forgive one's self can be significantly beneficial to an individual's emotional as well as mental well-being. The research indicates that the ability to forgive one's self for past offences can lead to decreased feelings of negative emotions such as shame and guilt, and can increase the use of more positive practices such as self-kindness and self-compassion. However, it has been indicated that it is possible for the process of self-forgiveness to be misinterpreted and therefore not accurately completed. This could potentially lead to increased feelings of regret or self-blame. In an attempt to avoid this, and increase the positive benefits associated with genuine self-forgiveness, a specific therapeutic model of self-forgiveness has been recommended, which can be used to encourage genuine self-forgiveness in offenders. The model that has been proposed has four key elements. These elements include responsibility, remorse, restoration and renewal.
  1. The therapeutic model suggests responsibility as the first necessary step towards genuine self-forgiveness. Research advises that in order to avoid the negative affect associated with emotions such as overwhelming guilt or regret, offenders must first recognize that they have hurt another individual, and accept the responsibility necessary for their actions.
  2. Once the individual has accepted responsibility for their offences, it is natural for them to experience feelings of remorse or guilt. However, these feelings can be genuinely processed and expressed preceding the need for restoration.
  3. The act of restoration allows the offending individual to make the necessary amends to the individual(s) they have hurt.
  4. The final component in the model of self-forgiveness is renewal'. The offending individual is able to genuinely forgive himself/herself for their past transgressions and can engage in more positive and meaningful behaviors such as self-compassion and self-kindness.
Despite the suggested model, research advises that the process of self-forgiveness is not always applicable for every individual. For example, individuals who have not actually caused others any harm or wrongdoing, but instead are suffering from negative emotions such as self-hatred or self-pity, such as victims of assault, might attempt self-forgiveness for their perceived offences. However, this would not be the process necessary for them to make their amends. Additionally, offenders who continue to offend others while attempting to forgive themselves for past offences demonstrate a reluctance to genuinely complete the four stages necessary for self-forgiveness. Research suggests that it is important to first gather exterior information about the individual's perceived offences as well as their needs and motivation for self-forgiveness.

Unapologetic forgiveness

Being unapologetic is often something that humans come across at some point in their lives, and there has been much research on if a person refuses to apologize or even recognized the wrongdoings. This can then often lead into how one would go into forgiving the unapologetic party and "the relationship between apologies and the adjectives 'apologetic' and 'unapologetic' is not quite so straightforward."

Character retributivism

  1. Forgiveness could be offered only at significant temporal remove from the wrongdoing.
  2. The enforcement of justice, at least with regard to punishing or rewarding, falls outside the purview of personal forgiveness.
  3. Forgiveness operates at a different level than justice.

Jean Hampton

Jean Hampton sees the decision to forgive the unrepentant wrongdoer as expressing a commitment "to see a wrongdoer in a new, more favorable light" as one who is not completely rotten or morally dead.

Principle of least astonishment

From Wikipedia, the free encyclopedia
 
The principle of least astonishment (POLA), also called the principle of least surprise (alternatively a "law" or "rule") applies to user interface and software design. A typical formulation of the principle, from 1984, is: "If a necessary feature has a high astonishment factor, it may be necessary to redesign the feature."

More generally, the principle means that a component of a system should behave in a way that most users will expect it to behave; the behavior should not astonish or surprise users.

Formulation

A textbook formulation is: "People are part of the system. The design should match the user's experience, expectations, and mental models."

The principle aims to leverage the pre-existing knowledge of users to minimize the learning curve, for instance by designing interfaces that borrow heavily from "functionally similar or analogous programs with which your users are likely to be familiar". User expectations in this respect may be closely related to a particular computing platform or tradition. For example, Unix command line programs are expected to follow certain conventions with respect to switches, and widgets of Microsoft Windows programs are expected to follow certain conventions with respect to keyboard shortcuts. In more abstract settings like an API, the expectation that function or method names intuitively match their behavior is another example. This practice also involves the application of sensible defaults.

When two elements of an interface conflict, or are ambiguous, the behavior should be that which will least surprise the user; in particular a programmer should try to think of the behavior that will least surprise someone who uses the program, rather than that behavior that is natural from knowing the inner workings of the program.

The choice of "least surprising" behavior can depend on the expected audience (for example, end users, programmers, or system administrators).

Examples

A website could have an input field that focuses automatically after the page loads, such as a search field (e.g. Google Custom Search), or the username field of a login form.

Sites offering keyboard shortcuts often allow pressing ? to see the available shortcuts. Examples include Gmail and Jira.

In Windows operating systems and some desktop environments for Linux, the F1 function key typically opens the help program for an application. A similar keyboard shortcut in macOS is Command+⇧ Shift+/. Users expect a help window or context menu when they press the usual help shortcut key(s). Software that instead uses this shortcut for another feature is likely to cause astonishment if no help appears. Malware may exploit user familiarity with regular shortcuts.

A programming language's standard library usually provides a function similar to the pseudocode ParseInteger(string, radix), which creates a machine-readable integer from a string of human-readable digits. The radix conventionally defaults to 10, meaning the string is interpreted as decimal (base 10). This function usually supports other bases, like binary (base 2) and octal (base 8), but only when they are specified explicitly. In a departure from this convention, JavaScript originally defaulted to base 8 for strings beginning with "0", causing developer confusion and software bugs. This was discouraged in ECMAScript 3 and dropped in ECMAScript 5.

User interface

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/User_interface 

The Reactable, an example of a tangible user interface

In the industrial design field of human-computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology.

Generally, the goal of user interface design is to produce a user interface which makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability). This generally means that the operator needs to provide minimal input to achieve the desired output, and also that the machine minimizes undesired outputs to the user.

User interfaces are composed of one or more layers, including a human-machine interface (HMI) that interfaces machines with physical input hardware such as keyboards, mice, or game pads, and output hardware such as computer monitors, speakers, and printers. A device that implements an HMI is called a human interface device (HID). Other terms for human-machine interfaces are man-machine interface (MMI) and, when the machine in question is a computer, human-computer interface. Additional UI layers may interact with one or more human senses, including: tactile UI (touch), visual UI (sight), auditory UI (sound), olfactory UI (smell), equilibrial UI (balance), and gustatory UI (taste).




Composite user interfaces (CUIs) are UIs that interact with two or more senses. The most common CUI is a graphical user interface (GUI), which is composed of a tactile UI and a visual UI capable of displaying graphics. When sound is added to a GUI, it becomes a multimedia user interface (MUI). There are three broad categories of CUI: standard, virtual and augmented. Standard composite user interfaces use standard human interface devices like keyboards, mice, and computer monitors. When the CUI blocks out the real world to create a virtual reality, the CUI is virtual and uses a virtual reality interface. When the CUI does not block out the real world and creates augmented reality, the CUI is augmented and uses an augmented reality interface. When a UI interacts with all human senses, it is called a qualia interface, named after the theory of qualia. CUI may also be classified by how many senses they interact with as either an X-sense virtual reality interface or X-sense augmented reality interface, where X is the number of senses interfaced with. For example, a Smell-O-Vision is a 3-sense (3S) Standard CUI with visual display, sound and smells; when virtual reality interfaces interface with smells and touch it is said to be a 4-sense (4S) virtual reality interface; and when augmented reality interfaces interface with smells and touch it is said to be a 4-sense (4S) augmented reality interface.

Overview


The user interface or human–machine interface is the part of the machine that handles the human–machine interaction. Membrane switches, rubber keypads and touchscreens are examples of the physical part of the Human Machine Interface which we can see and touch.

In complex systems, the human–machine interface is typically computerized. The term human–computer interface refers to this kind of system. In the context of computing, the term typically extends as well to the software dedicated to control the physical elements used for human-computer interaction.

The engineering of human–machine interfaces is enhanced by considering ergonomics (human factors). The corresponding disciplines are human factors engineering (HFE) and usability engineering (UE), which is part of systems engineering.

Tools used for incorporating human factors in the interface design are developed based on knowledge of computer science, such as computer graphics, operating systems, programming languages. Nowadays, we use the expression graphical user interface for human–machine interface on computers, as nearly all of them are now using graphics.

Multimodal interfaces allow users to interact using more than one modality of user input.

Terminology

A human–machine interface usually involves peripheral hardware for the INPUT and for the OUTPUT. Often, there is an additional component implemented in software, like e.g. a graphical user interface.
There is a difference between a user interface and an operator interface or a human–machine interface (HMI).
  • The term "user interface" is often used in the context of (personal) computer systems and electronic devices.
    • Where a network of equipment or computers are interlinked through an MES (Manufacturing Execution System)-or Host to display information.
    • A human-machine interface (HMI) is typically local to one machine or piece of equipment, and is the interface method between the human and the equipment/machine. An operator interface is the interface method by which multiple pieces of equipment that are linked by a host control system are accessed or controlled.
    • The system may expose several user interfaces to serve different kinds of users. For example, a computerized library database might provide two user interfaces, one for library patrons (limited set of functions, optimized for ease of use) and the other for library personnel (wide set of functions, optimized for efficiency).
  • The user interface of a mechanical system, a vehicle or an industrial installation is sometimes referred to as the human–machine interface (HMI). HMI is a modification of the original term MMI (man-machine interface). In practice, the abbreviation MMI is still frequently used although some may claim that MMI stands for something different now. Another abbreviation is HCI, but is more commonly used for human–computer interaction. Other terms used are operator interface console (OIC) and operator interface terminal (OIT). However it is abbreviated, the terms refer to the 'layer' that separates a human that is operating a machine from the machine itself. Without a clean and usable interface, humans would not be able to interact with information systems.
In science fiction, HMI is sometimes used to refer to what is better described as a direct neural interface. However, this latter usage is seeing increasing application in the real-life use of (medical) prostheses—the artificial extension that replaces a missing body part (e.g., cochlear implants).

In some circumstances, computers might observe the user and react according to their actions without specific commands. A means of tracking parts of the body is required, and sensors noting the position of the head, direction of gaze and so on have been used experimentally. This is particularly relevant to immersive interfaces.

History

The history of user interfaces can be divided into the following phases according to the dominant type of user interface:

1945–1968: Batch interface

IBM 029 card punch
IBM 029

In the batch era, computing power was extremely scarce and expensive. User interfaces were rudimentary. Users had to accommodate computers rather than the other way around; user interfaces were considered overhead, and software was designed to keep the processor at maximum utilization with as little overhead as possible.

The input side of the user interfaces for batch machines was mainly punched cards or equivalent media like paper tape. The output side added line printers to these media. With the limited exception of the system operator's console, human beings did not interact with batch machines in real time at all.

Submitting a job to a batch machine involved, first, preparing a deck of punched cards describing a program and a dataset. Punching the program cards wasn't done on the computer itself, but on keypunches, specialized typewriter-like machines that were notoriously bulky, unforgiving, and prone to mechanical failure. The software interface was similarly unforgiving, with very strict syntaxes meant to be parsed by the smallest possible compilers and interpreters.

Holes are punched in the card according to a prearranged code transferring the facts from the census questionnaire into statistics

Once the cards were punched, one would drop them in a job queue and wait. Eventually, operators would feed the deck to the computer, perhaps mounting magnetic tapes to supply another dataset or helper software. The job would generate a printout, containing final results or an abort notice with an attached error log. Successful runs might also write a result on magnetic tape or generate some data cards to be used in a later computation.

The turnaround time for a single job often spanned entire days. If one were very lucky, it might be hours; there was no real-time response. But there were worse fates than the card queue; some computers required an even more tedious and error-prone process of toggling in programs in binary code using console switches. The very earliest machines had to be partly rewired to incorporate program logic into themselves, using devices known as plugboards

Early batch systems gave the currently running job the entire computer; program decks and tapes had to include what we would now think of as operating system code to talk to I/O devices and do whatever other housekeeping was needed. Midway through the batch period, after 1957, various groups began to experiment with so-called “load-and-go” systems. These used a monitor program which was always resident on the computer. Programs could call the monitor for services. Another function of the monitor was to do better error checking on submitted jobs, catching errors earlier and more intelligently and generating more useful feedback to the users. Thus, monitors represented the first step towards both operating systems and explicitly designed user interfaces.

1969–present: Command-line user interface

Teletype Model 33
Teletype Model 33 ASR

Command-line interfaces (CLIs) evolved from batch monitors connected to the system console. Their interaction model was a series of request-response transactions, with requests expressed as textual commands in a specialized vocabulary. Latency was far lower than for batch systems, dropping from days or hours to seconds. Accordingly, command-line systems allowed the user to change his or her mind about later stages of the transaction in response to real-time or near-real-time feedback on earlier results. Software could be exploratory and interactive in ways not possible before. But these interfaces still placed a relatively heavy mnemonic load on the user, requiring a serious investment of effort and learning time to master.

The earliest command-line systems combined teleprinters with computers, adapting a mature technology that had proven effective for mediating the transfer of information over wires between human beings. Teleprinters had originally been invented as devices for automatic telegraph transmission and reception; they had a history going back to 1902 and had already become well-established in newsrooms and elsewhere by 1920. In reusing them, economy was certainly a consideration, but psychology and the Rule of Least Surprise mattered as well; teleprinters provided a point of interface with the system that was familiar to many engineers and users.

The VT100, introduced in 197″8, was the most popular VDT of all time. Most terminal emulators still default to VT100 mode.
DEC VT100 terminal
The widespread adoption of video-display terminals (VDTs) in the mid-1970s ushered in the second phase of command-line systems. These cut latency further, because characters could be thrown on the phosphor dots of a screen more quickly than a printer head or carriage can move. They helped quell conservative resistance to interactive programming by cutting ink and paper consumables out of the cost picture, and were to the first TV generation of the late 1950s and 60s even more iconic and comfortable than teleprinters had been to the computer pioneers of the 1940s.

Just as importantly, the existence of an accessible screen — a two-dimensional display of text that could be rapidly and reversibly modified — made it economical for software designers to deploy interfaces that could be described as visual rather than textual. The pioneering applications of this kind were computer games and text editors; close descendants of some of the earliest specimens, such as rogue(6), and vi(1), are still a live part of Unix tradition.

1985: SAA User Interface or Text-Based User Interface

In 1985, with the beginning of Microsoft Windows and other graphical user interfaces, IBM created what is called the Systems Application Architecture (SAA) standard which include the Common User Access (CUA) derivative. CUA successfully created what we know and use today in Windows, and most of the more recent DOS or Windows Console Applications will use that standard as well.

This defined that a pulldown menu system should be at the top of the screen, status bar at the bottom, shortcut keys should stay the same for all common functionality (F2 to Open for example would work in all applications that followed the SAA standard). This greatly helped the speed at which users could learn an application so it caught on quick and became an industry standard.

Interface design

Primary methods used in the interface design include prototyping and simulation.

Typical human–machine interface design consists of the following stages: interaction specification, interface software specification and prototyping:
  • Common practices for interaction specification include user-centered design, persona, activity-oriented design, scenario-based design, and resiliency design.
  • Common practices for interface software specification include use cases and constrain enforcement by interaction protocols (intended to avoid use errors).
  • Common practices for prototyping are based on libraries of interface elements (controls, decoration, etc.).

Principles of quality

All great interfaces share eight qualities or characteristics:
  1. Clarity: The interface avoids ambiguity by making everything clear through language, flow, hierarchy and metaphors for visual elements.
  2. Concision: It's easy to make the interface clear by over-clarifying and labeling everything, but this leads to interface bloat, where there is just too much stuff on the screen at the same time. If too many things are on the screen, finding what you're looking for is difficult, and so the interface becomes tedious to use. The real challenge in making a great interface is to make it concise and clear at the same time.
  3. Familiarity: Even if someone uses an interface for the first time, certain elements can still be familiar. Real-life metaphors can be used to communicate meaning.
  4. Responsiveness: A good interface should not feel sluggish. This means that the interface should provide good feedback to the user about what's happening and whether the user's input is being successfully processed.
  5. Consistency: Keeping your interface consistent across your application is important because it allows users to recognize usage patterns.
  6. Aesthetics: While you don't need to make an interface attractive for it to do its job, making something look good will make the time your users spend using your application more enjoyable; and happier users can only be a good thing.
  7. Efficiency: Time is money, and a great interface should make the user more productive through shortcuts and good design.
  8. Forgiveness: A good interface should not punish users for their mistakes but should instead provide the means to remedy them.

Principle of least astonishment

The principle of least astonishment (POLA) is a general principle in the design of all kinds of interfaces. It is based on the idea that human beings can only pay full attention to one thing at one time, leading to the conclusion that novelty should be minimized.

Principle of habit formation

If an interface is used persistently, the user will unavoidably develop habits for using the interface. The designer's role can thus be characterized as ensuring the user forms good habits. If the designer is experienced with other interfaces, they will similarly develop habits, and often make unconscious assumptions regarding how the user will interact with the interface.

A model of design criteria: User Experience Honeycomb

User interface / user experience guide
User Experience Design Honeycomb designed by Peter Morville
Peter Morville of Google designed the User Experience Honeycomb framework in 2004 when leading operations in user interface design. The framework was created to guide user interface design. It would act as a guideline for many web development students for a decade.
  1. Usable: Is the design of the system easy and simple to use? The application should feel familiar, and it should be easy to use.
  2. Useful: Does the application fulfill a need? A business’s product or service needs to be useful.
  3. Desirable: Is the design of the application sleek and to the point? The aesthetics of the system should be attractive, and easy to translate.
  4. Findable: Are users able to quickly find the information they're looking for? Information needs to be findable and simple to navigate. A user should never have to hunt for your product or information.
  5. Accessible: Does the application support enlarged text without breaking the framework? An application should be accessible to those with disabilities.
  6. Credible: Does the application exhibit trustworthy security and company details? An application should be transparent, secure, and honest.
  7. Valuable: Does the end-user think it's valuable? If all 6 criteria are met, the end-user will find value and trust in the application.

  1. Attentive user interfaces manage the user attention deciding when to interrupt the user, the kind of warnings, and the level of detail of the messages presented to the user.
  2. Batch interfaces are non-interactive user interfaces, where the user specifies all the details of the batch job in advance to batch processing, and receives the output when all the processing is done. The computer does not prompt for further input after the processing has started.
  3. Command line interfaces (CLIs) prompt the user to provide input by typing a command string with the computer keyboard and respond by outputting text to the computer monitor. Used by programmers and system administrators, in engineering and scientific environments, and by technically advanced personal computer users.
  4. Conversational interfaces enable users to command the computer with plain text English (e.g., via text messages, or chatbots) or voice commands, instead of graphic elements. These interfaces often emulate human-to-human conversations.
  5. Conversational interface agents attempt to personify the computer interface in the form of an animated person, robot, or other character (such as Microsoft's Clippy the paperclip), and present interactions in a conversational form.
  6. Crossing-based interfaces are graphical user interfaces in which the primary task consists in crossing boundaries instead of pointing.
  7. Direct manipulation interface is the name of a general class of user interfaces that allow users to manipulate objects presented to them, using actions that correspond at least loosely to the physical world.
  8. Gesture interfaces are graphical user interfaces which accept input in a form of hand gestures, or mouse gestures sketched with a computer mouse or a stylus.
  9. Graphical user interfaces (GUI) accept input via devices such as a computer keyboard and mouse and provide articulated graphical output on the computer monitor. There are at least two different principles widely used in GUI design: Object-oriented user interfaces (OOUIs) and application-oriented interfaces.
  10. Hardware interfaces are the physical, spatial interfaces found on products in the real world from toasters, to car dashboards, to airplane cockpits. They are generally a mixture of knobs, buttons, sliders, switches, and touchscreens.
  11. Holographic user interfaces provide input to electronic or electro-mechanical devices by passing a finger through reproduced holographic images of what would otherwise be tactile controls of those devices, floating freely in the air, detected by a wave source and without tactile interaction.
  12. Intelligent user interfaces are human-machine interfaces that aim to improve the efficiency, effectiveness, and naturalness of human-machine interaction by representing, reasoning, and acting on models of the user, domain, task, discourse, and media (e.g., graphics, natural language, gesture).
  13. Motion tracking interfaces monitor the user's body motions and translate them into commands, currently being developed by Apple.
  14. Multi-screen interfaces, employ multiple displays to provide a more flexible interaction. This is often employed in computer game interaction in both the commercial arcades and more recently the handheld markets.
  15. Natural-language interfaces are used for search engines and on webpages. User types in a question and waits for a response.
  16. Non-command user interfaces, which observe the user to infer their needs and intentions, without requiring that they formulate explicit commands.
  17. Object-oriented user interfaces (OOUI) are based on object-oriented programming metaphors, allowing users to manipulate simulated objects and their properties.
  18. Permission-driven user interfaces show or conceal menu options or functions depending on the user's level of permissions. The system is intended to improve the user experience by removing items that are unavailable to the user. A user who sees functions that are unavailable for use may become frustrated. It also provides an enhancement to security by hiding functional items from unauthorized persons.
  19. Reflexive user interfaces where the users control and redefine the entire system via the user interface alone, for instance to change its command verbs. Typically, this is only possible with very rich graphic user interfaces.
  20. Search interface is how the search box of a site is displayed, as well as the visual representation of the search results.
  21. Tangible user interfaces, which place a greater emphasis on touch and physical environment or its element.
  22. Task-focused interfaces are user interfaces which address the information overload problem of the desktop metaphor by making tasks, not files, the primary unit of interaction.
  23. Text-based user interfaces (TUIs) are user interfaces which interact via text. TUIs include command-line interfaces and text-based WIMP environments.
  24. Touchscreens are displays that accept input by touch of fingers or a stylus. Used in a growing amount of mobile devices and many types of point of sale, industrial processes and machines, self-service machines, etc.
  25. Touch user interface are graphical user interfaces using a touchpad or touchscreen display as a combined input and output device. They supplement or replace other forms of output with haptic feedback methods. Used in computerized simulators, etc.
  26. Voice user interfaces, which accept input and provide output by generating voice prompts. The user input is made by pressing keys or buttons, or responding verbally to the interface.
  27. Web-based user interfaces or web user interfaces (WUI) that accept input and provide output by generating web pages viewed by the user using a web browser program. Newer implementations utilize PHP, Java, JavaScript, AJAX, Apache Flex, .NET Framework, or similar technologies to provide real-time control in a separate program, eliminating the need to refresh a traditional HTML-based web browser. Administrative web interfaces for web-servers, servers and networked computers are often called control panels.
  28. Zero-input interfaces get inputs from a set of sensors instead of querying the user with input dialogs.
  29. Zooming user interfaces are graphical user interfaces in which information objects are represented at different levels of scale and detail, and where the user can change the scale of the viewed area in order to show more detail.

LCD television

Liquid-crystal-display televisions (LCD TVs) are television sets that use liquid-crystal displays to produce images. They are, by far, the most widely produced and sold television display type. LCD TVs are thin and light, but have some disadvantages compared to other display types such as high power consumption, poorer contrast ratio, and inferior color gamut.

LCD TVs rose in popularity in the early years of the 21st century, surpassing sales of cathode ray tube televisions worldwide in 2007. Sales of CRT TVs dropped rapidly after that, as did sales of competing technologies such as plasma display panels and rear-projection television.

History

Early efforts

Passive matrix LCDs first became common as portable computer displays in the 1980s, competing for market share with plasma displays. The LCDs had very slow refresh rates that blurred the screen even with scrolling text, but their light weight and low cost were major benefits. Screens using reflective LCDs required no internal light source, making them particularly well suited to laptop computers. Refresh rates of early devices were too slow to be useful for television.




Portable televisions were a target application for LCDs. LCDs consumed far less battery power than even the miniature tubes used in portable televisions of the era. In 1980, Hattori Seiko's R&D group began development on color LCD pocket televisions. In 1982, Seiko Epson released the first LCD television, the Epson TV Watch, a small wrist-worn active-matrix LCD television. Sharp Corporation introduced the dot matrix TN-LCD in 1983, and Casio introduced its TV-10 portable TV. In 1984, Epson released the ET-10, the first full-color pocket LCD television. That same year Citizen Watch introduced the Citizen Pocket TV, a 2.7-inch color LCD TV, with the first commercial TFT LCD display. 


Throughout this period, screen sizes over 30" were rare as these formats would start to appear blocky at normal seating distances when viewed on larger screens. LCD projection systems were generally limited to situations where the image had to be viewed by a larger audience. At the same time, plasma displays could easily offer the performance needed to make a high quality display, but suffered from low brightness and very high power consumption. Still, some experimentation with LCD televisions took place during this period. In 1988, Sharp introduced a 14-inch active-matrix full-color full-motion TFT-LCD. These were offered primarily as high-end items, and were not aimed at the general market. This led to Japan launching an LCD industry, which developed larger-size LCDs, including TFT computer monitors and LCD televisions. Epson developed the 3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988. Epson's VPJ-700, released in January 1989, was the world's first compact, full-color LCD projector.

Market takeover

In 2006, LCD prices started to fall rapidly and their screen sizes increased, although plasma televisions maintained a slight edge in picture quality and a price advantage for sets at the critical 42" size and larger. By late 2006, several vendors were offering 42" LCDs, albeit at a premium price, encroaching upon plasma's only stronghold. More decisively, LCDs offered higher resolutions and true 1080p support, while plasmas were stuck at 720p, which made up for the price difference.

Predictions that prices for LCDs would rapidly drop through 2007 led to a "wait and see" attitude in the market, and sales of all large-screen televisions stagnated while customers watched to see if this would happen. Plasmas and LCDs reached price parity in 2007, with the LCD's higher resolution being a 'winning point' for many sales. By late 2007, it was clear plasmas would lose out to LCDs during the critical Christmas sales season. This was in spite of plasmas continuing to hold an image quality advantage, but as the president of Chunghwa Picture Tubes noted after shutting down their plasma production line, "(g)lobally, so many companies, so many investments, so many people have been working in this area, on this product. So they can improve so quickly."

When the sales figures for the 2007 Christmas season were finally tallied, analysts were surprised to find that not only had LCD outsold plasma, but CRTs as well, during the same period. This development drove competing large-screen systems from the market almost overnight. Plasma had overtaken rear-projection systems in 2005. The same was true for CRTs, which lasted only a few months longer; Sony ended sales of their famous Trinitron in most markets in 2007, and shut down the final plant in March 2008. The February 2009 announcement that Pioneer Electronics was ending production of the plasma screens was widely considered the tipping point in that technology's history as well.

LCD's dominance in the television market accelerated rapidly. It was the only technology that could scale both up and down in size, covering both the high-end market for large screens in the 40 to 50" class, as well as customers looking to replace their existing smaller CRT sets in the 14 to 30" range. Building across these wide scales quickly pushed the prices down across the board.

In 2008, LCD TV shipments were up 33 percent year-on-year compared to 2007 to 105 million units. In 2009, LCD TV shipments raised to 146 million units (69% from the total of 211 million TV shipments). In 2010, LCD TV shipments reached 187.9 million units (from an estimated total of 247 million TV shipments).

Larger size displays continued to be released throughout the decade:
  • In October 2004, Sharp announced the successful manufacture of a 65" panel.
  • In March 2005, Samsung announced an 82" LCD panel.
  • In August 2006, LG.Philips LCD announced a 100" LCD television
  • In January 2007, Sharp displayed a 108" LCD panel under the AQUOS brand name at CES in Las Vegas.

Competing systems

In spite of LCD's dominance of the television field, other technologies continued to be developed to address its shortcomings. Whereas LCDs produce an image by selectively blocking a backlight, organic LED, microLED, field-emission display and surface-conduction electron-emitter display technologies all produce an illuminated image directly. In comparison to LCDs all of these technologies offer better viewing angles, much higher brightness and contrast ratio (as much as 5,000,000:1), and better color saturation and accuracy. They also use less power, and in theory they are less complex and less expensive to build.

Manufacturing these screens proved to be more difficult than originally thought, however. Sony abandoned their field-emission display project in March 2009, but continued to work on OLED sets. Canon continued development of their surface-conduction electron-emitter display technology, but announced they would not attempt to introduce sets to market for the foreseeable future.

Samsung announced that 14.1 and 31 inch OLED sets were "production ready" at the SID 2009 trade show in San Antonio.
