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] that emotions are discrete and fundamentally different constructs
The theory offers an explanation for the evolution of common facial expressions of emotion in mammals. Little experimental work has been done to extend the theory, however. Carroll Izard discussed gains and losses associated with the evolution of emotions.
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 .
The theory of constructed emotion (formerly the conceptual act model of emotion [1]) is a theory in affective science proposed by Lisa Feldman Barrett to explain the experience and perception of emotion. [2] [3] The theory posits that instances of emotion are constructed predictively by the brain in the moment as needed.
A common way in which emotions are conceptualized in sociology is in terms of the multidimensional characteristics including cultural or emotional labels (for example, anger, pride, fear, happiness), physiological changes (for example, increased perspiration, changes in pulse rate), expressive facial and body movements (for example, smiling ...
Plutchik's psychoevolutionary theory of basic emotions has ten postulates. The concept of emotion is applicable to all evolutionary levels and applies to all animals including humans. Emotions have an evolutionary history and have evolved various forms of expression in different species.
The theory emphasises on the discrete emotions along with five assumptions (one: the fundamental emotions; two: the fundamental emotions each have distinctive motivational properties; three: these fundamental emotions lead to different experiences and behaviour; four: emotions interact and one emotion can trigger another; five: emotions ...
Appraisal theory is the theory in psychology that emotions are extracted from our evaluations (appraisals or estimates) of events that cause specific reactions in different people. Essentially, our appraisal of a situation causes an emotional, or affective, response that is going to be based on that appraisal. [ 1 ]
