Discrete emotion theory is the claim that there is a small number of core emotions. For example, Silvan Tomkins (1962, 1963) concluded that there are nine basic affects which correspond with what we come to know as emotions: interest, enjoyment, surprise, distress, fear, anger, shame, dissmell (reaction to bad smell) and disgust. More recently, Carroll Izard at the University of Delaware factor analytically delineated 12 discrete emotions labeled: Interest, Joy, Surprise, Sadness, Anger, Disgust, Contempt, Self-Hostility, Fear, Shame, Shyness, and Guilt (as measured via his Differential Emotions Scale or DES-IV). [1] [2] [3]
Discrete emotion theory states that these specific core emotions are biologically determined emotional responses whose expression and recognition is fundamentally the same for all individuals regardless of ethnic or cultural differences.
The biological and physiological underpinnings of emotions were discussed [4] by Aristotle in De Anima , by Charles Darwin in The Expression of the Emotions in Man and Animals (1872), by William James (1884), [5] and by John Dewey (1895). [6]
Tomkins' (1962, 1963) idea was influenced by Darwin's concept. He proposed that there is a limited number of inborn basic "affect programs": surprise, interest-excitement, enjoyment-joy, anger-rage, fear-terror, shame-humiliation, distress-anguish, disgust, dissmell. These affects are not necessarily recognizable consciously, but they become recognizable as emotions when they combine meaningfully with personal and cultural experience.
John Watson believed that emotions could be described in physical states.
Edwin Newman and colleagues believed emotions were a combination of one's experiences, physiology, and behaviour.
Ross Buck came up with the facial feedback hypothesis, "that skeletal muscle feedback from facial expressions plays a causal role in regulating emotional experience and behaviour". [7]
After performing a series of cross-cultural studies, Paul Ekman and Carroll Izard reported that there are various similarities in the way people across the world produce and recognize the facial expressions of at least six emotions. [8]
A study investigated whether the emotions behind specific facial expressions could be identified by people from a group in New Guinea who had had little to no exposure to Westerners and who had never seen a movie. The researchers showed the people pictures of people portraying six different emotions that are known as core emotions: happiness, anger, sadness, disgust, surprise and fear. Researchers found that the people of New Guinea could in fact point out the different emotions and distinguish between them. [9]
Various parts in the brain can trigger different emotions. For example, the amygdala is the locus of fear. The amygdala senses fear and it orchestrates physical actions and emotions. [10] From this experiment, researchers concluded that these specific emotions are innate. They also looked at pictures of people ranging in age from infants to elders, and saw that the core emotions look the same, further supporting the discrete emotion hypothesis. Additionally, deaf and blind children show typical facial expressions for these same core emotions.
James Russell and Lisa Barrett [10] have criticized [4] discrete emotion theory on several points. Those include problems in finding correspondences between discrete emotions and brain activity, variability in facial expressions and behavior, [11] and gradations in emotional responses.
Emotions are physical and mental states brought on by neurophysiological changes, variously associated with thoughts, feelings, behavioral responses, and a degree of pleasure or displeasure. There is no scientific consensus on a definition. Emotions are often intertwined with mood, temperament, personality, disposition, or creativity.
A facial expression is one or more motions or positions of the muscles beneath the skin of the face. These movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species.
Pathognomy is "a 'semiotik' of the transient features of someone's face or body, be it voluntary or involuntary". Examples of this can be laughter and winking to the involuntary such as sneezing or coughing. By studying the features or expressions, there is then an attempt to infer the mental state and emotion felt by the individual.
Paul Ekman is an American psychologist and professor emeritus at the University of California, San Francisco who is a pioneer in the study of emotions and their relation to facial expressions. He was ranked 59th out of the 100 most cited psychologists of the twentieth century. Ekman conducted seminal research on the specific biological correlations of specific emotions, attempting to demonstrate the universality and discreteness of emotions in a Darwinian approach.
Amusement is the state of experiencing humorous and entertaining events or situations while the person or animal actively maintains the experience, and is associated with enjoyment, happiness, laughter and pleasure. It is an emotion with positive valence and high physiological arousal.
Affect theory is a theory that seeks to organize affects, sometimes used interchangeably with emotions or subjectively experienced feelings, into discrete categories and to typify their physiological, social, interpersonal, and internalized manifestations. The conversation about affect theory has been taken up in psychology, psychoanalysis, neuroscience, medicine, interpersonal communication, literary theory, critical theory, media studies, and gender studies, among other fields. Hence, affect theory is defined in different ways, depending on the discipline.
An emotional expression is a behavior that communicates an emotional state or attitude. It can be verbal or nonverbal, and can occur with or without self-awareness. Emotional expressions include facial movements like smiling or scowling, simple behaviors like crying, laughing, or saying "thank you," and more complex behaviors like writing a letter or giving a gift. Individuals have some conscious control of their emotional expressions; however, they need not have conscious awareness of their emotional or affective state in order to express emotion.
Affective neuroscience is the study of how the brain processes emotions. This field combines neuroscience with the psychological study of personality, emotion, and mood. The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.
A frown is a facial expression in which the eyebrows are brought together, and the forehead is wrinkled, usually indicating displeasure, sadness or worry, or less often confusion or concentration. The appearance of a frown varies by culture. An alternative usage in North America is thought of as an expression of the mouth. In those cases when used iconically, as with an emoticon, it is entirely presented by the curve of the lips forming a down-open curve. The mouth expression is also commonly referred to in the colloquial English phrase, especially in the United States, to "turn that frown upside down" which indicates changing from sad to happy.
Silvan Solomon Tomkins was a psychologist and personality theorist who developed both affect theory and script theory. Following the publication of the third volume of his book Affect Imagery Consciousness in 1991, his body of work received renewed interest, leading to attempts by others to summarize and popularize his theories.
The facial feedback hypothesis, rooted in the conjectures of Charles Darwin and William James, is that one's facial expression directly affects their emotional experience. Specifically, physiological activation of the facial regions associated with certain emotions holds a direct effect on the elicitation of such emotional states, and the lack of or inhibition of facial activation will result in the suppression of corresponding emotional states.
According to some theories, emotions are universal phenomena, albeit affected by culture. Emotions are "internal phenomena that can, but do not always, make themselves observable through expression and behavior". While some emotions are universal and are experienced in similar ways as a reaction to similar events across all cultures, other emotions show considerable cultural differences in their antecedent events, the way they are experienced, the reactions they provoke and the way they are perceived by the surrounding society. According to other theories, termed social constructionist, emotions are more deeply culturally influenced. The components of emotions are universal, but the patterns are social constructions. Some also theorize that culture is affected by the emotions of the people.
Carroll Ellis Izard was an American research psychologist known for his contributions to differential emotions theory (DET), and the Maximally Discriminative Affect Coding System (MAX) on which he worked with Paul Ekman. Izard also undertook empirical studies into the facial feedback hypothesis according to which emotions which have different functions also cause facial expressions which in turn provide us with cues about what emotion a person is feeling. In addition, Izard constructed a multidimensional self-report measure – the Differential Emotions Scale – currently in its 4th edition (DES-IV). His later research focused on emotional development in young children and the development and testing of his Emotions Course for Young Children.
Emotion classification, the means by which one may distinguish or contrast one emotion from another, is a contested issue in emotion research and in affective science. Researchers have approached the classification of emotions from one of two fundamental viewpoints:
Affect consciousness refers to an individual's ability to consciously perceive, tolerate, reflect upon, and express affects. These four abilities are operationalized as degrees of awareness, tolerance, emotional (nonverbal) expression, and conceptual (verbal) expression of each of the following eleven affect categories:
Affect measures are used in the study of human affect, and refer to measures obtained from self-report studies asking participants to quantify their current feelings or average feelings over a longer period of time. Even though some affect measures contain variations that allow assessment of basic predispositions to experience a certain emotion, tests for such stable traits are usually considered to be personality tests.
The study of the evolution of emotions dates back to the 19th century. Evolution and natural selection has been applied to the study of human communication, mainly by Charles Darwin in his 1872 work, The Expression of the Emotions in Man and Animals. Darwin researched the expression of emotions in an effort to support his materialist theory of unguided evolution. He proposed that much like other traits found in animals, emotions apparently also evolved and were adapted over time. His work looked at not only facial expressions in animals and specifically humans, but attempted to point out parallels between behaviors in humans and other animals.
Emotion perception refers to the capacities and abilities of recognizing and identifying emotions in others, in addition to biological and physiological processes involved. Emotions are typically viewed as having three components: subjective experience, physical changes, and cognitive appraisal; emotion perception is the ability to make accurate decisions about another's subjective experience by interpreting their physical changes through sensory systems responsible for converting these observed changes into mental representations. The ability to perceive emotion is believed to be both innate and subject to environmental influence and is also a critical component in social interactions. How emotion is experienced and interpreted depends on how it is perceived. Likewise, how emotion is perceived is dependent on past experiences and interpretations. Emotion can be accurately perceived in humans. Emotions can be perceived visually, audibly, through smell and also through bodily sensations and this process is believed to be different from the perception of non-emotional material.
Facial expressions are used to communicate emotions. They can also occur solitarily, without other people being present. People often imagine themselves in social situations when alone, resulting in solitary facial expressions. Toddlers and children in early childhood use social cues and contexts to discriminate and recognize facial expressions. They develop at this early stage facial expressions in order to provoke reactions from their caregivers and receive nurturance and support. Children reflect their peers' emotions in their own expressions for social interaction.
The Differential Emotions Scale (DES) is a multidimensional self-report device for assessment of an individual's emotions. The DES helps measure mood based on Carroll Izard's differential emotions theory, The DES consists of thirty items, three for each of the ten fundamental emotions as visualized by Izard: interest, joy, surprise, sadness, anger, disgust, contempt, fear, shame/ shyness, and guilt, which are represented on 5-point Likert scale. There are currently four different versions of the scale. Despite the different versions, the basic idea of are very similar. Participants are asked to rate each of the emotions on a scale, and depending on the instructions given, they either rate their current feelings, feelings over the past week, or over long-term traits. The DES is similar to other scales such as the Multiple Affect Adjective Check List (MAACL) and the Multiple Affect Adjective Check List-Revised (MAACL-R) which are used to assess either the state or trait affect by varying the time of which instructions are given to the participants.
