The cognitive-affective personality system or cognitive-affective processing system (CAPS) is a contribution to the psychology of personality proposed by Walter Mischel and Yuichi Shoda in 1995. According to the cognitive-affective model, behavior is best predicted from a comprehensive understanding of the person, the situation, and the interaction between person and situation.[1]


Cognitive-Affective Processing System

Cognitive-affective theorists argue that behavior is not the result of some global personality trait; instead, it arises from individual's perceptions of themself in a particular situation. However, inconsistencies in behavior are not due solely to the situation; inconsistent behaviors reflect stable patterns of variation within the person. These stable variations in behavior present themselves in the following framework: If A, then X; but if B, then Y. People's pattern of variability is the behavioral signature of their personality, or their stable pattern of behaving differently in various situations. According to this model, personality depends on situation variables, and consists of cognitive-affective units (all those psychological, social, and physiological aspects of people that allow them to interact with their environment in a relatively stable manner).

The authors identified five cognitive-affective units:


The cognitive-affective processing system theory provides a comprehensive view that accounts for both the variability of behavior and the stability in the personality system that generates it. Rather than dichotomizing personality research into the study of dispositions or processes, the theory allows the pursuit of both - structure and dynamics - as aspects of the same unitary system.[1][2]
