ABSTRACT
This chapter provides a review of the basic concepts and relationships of affect that have been studied in three reference disciplines of information systems (IS): psychology, marketing and consumer research, and organizational and social psychology. Attitude often has been a dependent variable in organizational psychology, marketing, and consumer research. The distinction between trait and state is well studied in psychology, marketing and consumer research, and organizational and social psychology. The organizational behavior literature supports the causal relationship between affective trait and state. Epstein created cognitive-experiential self-theory (CEST), in which affect and cognition operate in parallel. Affect infusion model (AIM) identified four processing strategies, in which affect may have different influences on cognition, such as performance appraisal, reactions to feedback, and task perceptions. Psychological research suggests that the influence of a trait variable on behavior is mediated by beliefs and affective factors.
