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:[citation needed]

In discrete emotion theory, all humans are thought to have an innate set of basic emotions that are cross-culturally recognizable. These basic emotions are described as "discrete" because they are believed to be distinguishable by an individual's facial expression and biological processes.[1] Theorists have conducted studies to determine which emotions are basic. A popular example is Paul Ekman and his colleagues' cross-cultural study of 1992, in which they concluded that the six basic emotions are anger, disgust, fear, happiness, sadness, and surprise.[2] Ekman explains that there are particular characteristics attached to each of these emotions, allowing them to be expressed in varying degrees in a non-verbal manner.[3][4] Each emotion acts as a discrete category rather than an individual emotional state.[5]
Humans' subjective experience is that emotions are clearly recognizable in ourselves and others. This apparent ease of recognition has led to the identification of a number of emotions that are said to be basic, and universal among all people. However, a debate among experts has questioned this understanding of what emotions are. There has been recent discussion of the progression on the different views of emotion over the years.[6]
On "basic emotion" accounts, activation of an emotion, such as anger, sadness, or fear, is "triggered" by the brain's appraisal of a stimulus or event with respect to the perceiver's goals or survival. In particular, the function, expression, and meaning of different emotions are hypothesized to be biologically distinct from one another. A theme common to many basic emotions theories is that there should be functional signatures that distinguish different emotions: we should be able to tell what emotion a person is feeling by looking at his or her brain activity and/or physiology. Furthermore, knowledge of what the person is seeing or the larger context of the eliciting event should not be necessary to deduce what the person is feeling from observing the biological signatures.[5]
On "constructionist" accounts, the emotion a person feels in response to a stimulus or event is "constructed" from more elemental biological and psychological ingredients. Two hypothesized ingredients are "core affect" (characterized by, e.g., hedonic valence and physiological arousal) and conceptual knowledge (such as the semantic meaning of the emotion labels themselves, e.g., the word "anger"). A theme common to many constructionist theories is that different emotions do not have specific locations in the nervous system or distinct physiological signatures, and that context is central to the emotion a person feels because of the accessibility of different concepts afforded by different contexts.[7]
For both theoretical and practical reasons researchers define emotions according to one or more dimensions. In his philosophical treatise, The Passions of the Soul, Descartes defines and investigates the six primary passions (Wonder, love, hate, desire, joy, and sadness). In 1897, Wilhelm Max Wundt, the father of modern psychology, proposed that emotions can be described by three dimensions: "pleasurable versus unpleasurable", "arousing or subduing", and "strain or relaxation".[8] In 1954, Harold Schlosberg named three dimensions of emotion: "pleasantness–unpleasantness", "attention–rejection" and "level of activation".[9]
Dimensional models of emotion attempt to conceptualize human emotions by defining where they lie in two or three dimensions. Most dimensional models incorporate valence and arousal or intensity dimensions. Dimensional models of emotion suggest that a common and interconnected neurophysiological system is responsible for all affective states.[10] These models contrast theories of basic emotion, which propose that different emotions arise from separate neural systems.[10] Several dimensional models of emotion have been developed, though there are just a few that remain as the dominant models currently accepted by most.[11] The two-dimensional models that are most prominent are the circumplex model, the vector model, and the Positive Activation – Negative Activation (PANA) model.[11]
The circumplex model of emotion was developed by James Russell.[12] This model suggests that emotions are distributed in a two-dimensional circular space, containing arousal and valence dimensions. Arousal represents the vertical axis and valence represents the horizontal axis, while the center of the circle represents a neutral valence and a medium level of arousal.[11] In this model, emotional states can be represented at any level of valence and arousal, or at a neutral level of one or both of these factors. Circumplex models have been used most commonly to test stimuli of emotion words, emotional facial expressions, and affective states.[13]
Russell and Lisa Feldman Barrett describe their modified circumplex model as representative of core affect, or the most elementary feelings that are not necessarily directed toward anything. Different prototypical emotional episodes, or clear emotions that are evoked or directed by specific objects, can be plotted on the circumplex, according to their levels of arousal and pleasure.[14]
The vector model of emotion appeared in 1992.[16] This two-dimensional model consists of vectors that point in two directions, representing a "boomerang" shape. The model assumes that there is always an underlying arousal dimension, and that valence determines the direction in which a particular emotion lies. For example, a positive valence would shift the emotion up the top vector and a negative valence would shift the emotion down the bottom vector.[11] In this model, high arousal states are differentiated by their valence, whereas low arousal states are more neutral and are represented near the meeting point of the vectors. Vector models have been most widely used in the testing of word and picture stimuli.[13]
The positive activation – negative activation (P.A.N.A.) or "consensual" model of emotion, originally created by Watson and Tellegen in 1985,[17] suggests that positive affect and negative affect are two separate systems. Similar to the vector model, states of higher arousal tend to be defined by their valence, and states of lower arousal tend to be more neutral in terms of valence.[11] In the P.A.N.A. model, the vertical axis represents low to high positive affect and the horizontal axis represents low to high negative affect. The dimensions of valence and arousal lay at a 45-degree rotation over these axes.[17]
Robert Plutchik offers a three-dimensional model that is a hybrid of both basic-complex categories and dimensional theories. It arranges emotions in concentric circles where inner circles are more basic and outer circles more complex. Notably, outer circles are also formed by blending the inner circle emotions. Plutchik's model, as Russell's, emanates from a circumplex representation, where emotional words were plotted based on similarity.[18] There are numerous emotions, which appear in several intensities and can be combined in various ways to form emotional "dyads".[19][20][21][22][23]
The PAD emotional state model is a psychological model developed by Albert Mehrabian and James A. Russell to describe and measure emotional states. PAD uses three numerical dimensions to represent all emotions.[24][25] The PAD dimensions are Pleasure, Arousal and Dominance.
Ethnographic and cross-cultural studies of emotions have shown the variety of ways in which emotions differ with cultures. Because of these differences, many cross-cultural psychologists and anthropologists challenge the idea of universal classifications of emotions altogether. Cultural differences have been observed in the way in which emotions are valued, expressed, and regulated. The social norms for emotions, such as the frequency with or circumstances in which they are expressed, also vary drastically.[26][27] For example, the demonstration of anger is encouraged by Kaluli people, but condemned by Utku Inuit.[28]
The largest piece of evidence that disputes the universality of emotions is language. Differences within languages directly correlate to differences in emotion taxonomy. Languages differ in that they categorize emotions based on different components. Some may categorize by event types, whereas others categorize by action readiness. Furthermore, emotion taxonomies vary due to the differing implications emotions have in different languages.[26] That being said, not all English words have equivalents in all other languages and vice versa, indicating that there are words for emotions present in some languages but not in others.[29] Emotions such as the schadenfreude in German and saudade in Portuguese are commonly expressed in emotions in their respective languages, but lack an English equivalent.
Some languages do not differentiate between emotions that are considered to be the basic emotions in English. For instance, certain African languages have one word for both anger and sadness, and others for shame and fear. There is ethnographic evidence that even challenges the universality of the category "emotions" because certain cultures lack a specific word relating to the English word "emotions".[27]
Emotions are categorized into various affects, which correspond to the current situation.[30] An affect is the range of feeling experienced.[31] Both positive and negative emotions are needed in our daily lives.[32] Many theories of emotion have been proposed,[33] with contrasting views.[34]
A 2009 review[44] of theories of emotion identifies and contrasts fundamental emotions according to three key criteria for mental experiences that:
The combination of these attributes distinguishes emotions from sensations, feelings and moods.
| Kind of emotion | Positive emotions | Negative emotions |
|---|---|---|
| Related to object properties | Interest, curiosity, enthusiasm | Indifference, habituation, boredom |
| Attraction, desire, admiration | Aversion, disgust, revulsion | |
| Surprise, amusement | Alarm, panic | |
| Future appraisal | Hope, excitement | Fear, anxiety, dread |
| Event-related | Gratitude, thankfulness | Anger, rage |
| Joy, elation, triumph, jubilation | Sorrow, grief | |
| Patience | Frustration, restlessness | |
| Contentment | Discontentment, disappointment | |
| Self-appraisal | Humility, modesty | Pride, arrogance |
| Social | Charity | Avarice, greed, miserliness, envy, jealousy |
| Sympathy | Cruelty | |
| Cathected | Love | Hate |
Researchers distinguish several emotion dynamics, most commonly how intense (mean level), variable (fluctuations), inert (temporal dependency), instable (magnitude of moment-to-moment fluctuations), or differentiated someone's emotions are (the specificity of granularity of emotions), and whether and how an emotion augments or blunts other emotions.[45] Meta-analytic reviews show systematic developmental changes in emotion dynamics throughout childhood and adolescence and substantial between-person differences.[45]
The emotion annotation and representation language (EARL) proposed by the Human-Machine Interaction Network on Emotion (HUMAINE) classifies 48 emotions.[46]

In 1980, Robert Plutchik diagrammed a wheel of eight emotions: joy, trust, fear, surprise, sadness, disgust, anger and anticipation, inspired by his Ten Postulates.[49][50] Plutchik also theorized twenty-four "Primary", "Secondary", and "Tertiary" dyads (feelings composed of two emotions).[51][52][53][54][55][56][57] The wheel emotions can be paired in four groups:
There are also triads, emotions formed from 3 primary emotions, though Plutchik never describes in any detail what the triads might be.[58] This leads to a combination of 24 dyads and 32 triads, making 56 emotions at 1 intensity level.[59] Emotions can be mild or intense;[60] for example, distraction is a mild form of surprise, and rage is an intense form of anger. The kinds of relation between each pair of emotions are:
| Mild emotion | Mild opposite | Basic emotion | Basic opposite | Intense emotion | Intense opposite |
|---|---|---|---|---|---|
| Serenity | Pensiveness, Gloominess | Joy, Cheerfulness | Sadness, Dejection | Ecstasy, Elation | Grief, Sorrow |
| Acceptance, Tolerance | Boredom, Dislike | Trust | Disgust, Aversion | Admiration, Adoration | Loathing, Revulsion |
| Apprehension, Dismay | Annoyance, Irritation | Fear, Fright | Anger, Hostility | Terror, Panic | Rage, Fury |
| Distraction, Uncertainty | Interest, Attentiveness | Surprise | Anticipation, Expectancy | Amazement, Astonishment | Vigilance |
| Human feelings | Emotions | Opposite feelings | Emotions |
|---|---|---|---|
| Optimism, Courage | Anticipation + Joy | Disapproval, Disappointment | Surprise + Sadness |
| Hope, Fatalism | Anticipation + Trust | Unbelief, Shock | Surprise + Disgust |
| Anxiety, Dread | Anticipation + Fear | Outrage, Hate | Surprise + Anger |
| Love, Friendliness | Joy + Trust | Remorse, Misery | Sadness + Disgust |
| Guilt, Excitement | Joy + Fear | Envy, Sullenness | Sadness + Anger |
| Delight, Doom | Joy + Surprise | Pessimism | Sadness + Anticipation |
| Submission, Modesty | Trust + Fear | Contempt, Scorn | Disgust + Anger |
| Curiosity | Trust + Surprise | Cynicism | Disgust + Anticipation |
| Sentimentality, Resignation | Trust + Sadness | Morbidness, Derisiveness | Disgust + Joy |
| Awe, Alarm | Fear + Surprise | Aggressiveness, Vengeance | Anger + Anticipation |
| Despair | Fear + Sadness | Pride, Victory | Anger + Joy |
| Shame, Prudishness | Fear + Disgust | Dominance | Anger + Trust |
| Human feelings | Emotions |
|---|---|
| Bittersweetness | Joy + Sadness |
| Ambivalence | Trust + Disgust |
| Frozenness | Fear + Anger |
| Confusion | Surprise + Anticipation |
Similar emotions in the wheel are adjacent to each other.[61] Anger, Anticipation, Joy, and Trust are positive in valence, while Fear, Surprise, Sadness, and Disgust are negative in valence. Anger is classified as a "positive" emotion because it involves "moving toward" a goal,[62] while surprise is negative because it is a violation of someone's territory.[63] The emotion dyads each have half-opposites and exact opposites:[64]
| + | Sadness | Joy |
|---|---|---|
| Anticipation | Pessimism | Optimism |
| Surprise | Disapproval | Delight |
| + | Disgust | Trust |
|---|---|---|
| Joy | Morbidness | Love |
| Sadness | Remorse | Sentimentality |
| + | Fear | Anger |
|---|---|---|
| Trust | Submission | Dominance |
| Disgust | Shame | Contempt |
| + | Surprise | Anticipation |
|---|---|---|
| Anger | Outrage | Aggressiveness |
| Fear | Awe | Anxiety |
| + | Surprise | Anticipation |
|---|---|---|
| Trust | Curiosity | Hope |
| Disgust | Unbelief | Cynicism |
| + | Fear | Anger |
|---|---|---|
| Joy | Guilt | Pride |
| Sadness | Despair | Envy |
MIT researchers [65] published a paper titled "An Affective Model of Interplay Between Emotions and Learning: Reengineering Educational Pedagogy—Building a Learning Companion" that lists six axes of emotions with different opposite emotions, and different emotions coming from ranges.[65]
| Axis | -1.0 | -0.5 | 0 | 0 | +0.5 | +1.0 |
|---|---|---|---|---|---|---|
| Anxiety – Confidence | Anxiety | Worry | Discomfort | Comfort | Hopeful | Confident |
| Boredom – Fascination | Ennui | Boredom | Indifference | Interest | Curiosity | Intrigue |
| Frustration – Euphoria | Frustration | Puzzlement | Confusion | Insight | Enlightenment | Epiphany |
| Dispirited – Encouraged | Dispirited | Disappointed | Dissatisfied | Satisfied | Thrilled | Enthusiastic |
| Terror – Enchantment | Terror | Dread | Apprehension | Calm | Anticipatory | Excited |
| Humiliation – Pride | Humiliated | Embarrassed | Self-conscious | Pleased | Satisfied | Proud |
They also made a model labeling phases of learning emotions.[65]
| Negative Affect | Positive Affect | |
|---|---|---|
| Constructive Learning | Disappointment, Puzzlement, Confusion | Awe, Satisfaction, Curiosity |
| Un-learning | Frustration, Discard, | Hopefulness, Fresh research |
Tiffany Watt Smith listed 154 different worldwide emotions and feelings.[66]
Scientists map twenty-one different facial emotions[68][69] expanded from Paul Ekman's six basic emotions of anger, disgust, fear, happiness, sadness, and surprise:
| Fearful | Angry | Surprised | Disgusted | ||
| Happy | Happily Surprised | Happily Disgusted | |||
| Sad | Sadly Fearful | Sadly Angry | Sadly Surprised | Sadly Disgusted | |
| Appalled | Fearfully Angry | Fearfully Surprised | Fearfully Disgusted | ||
