Unveiling an exclusive link: Predicting behavior with personality, situation perception, and affect in a preregistered experience sampling study.

Abstract

Affect and situation perception are intertwined in any given situation, but the extent to which both predict behavior jointly and uniquely has not yet been systematically examined so far. Using 2 studies with experience sampling methodology (ESM), we examine how trait-like variables (Big Six, trait affect, general situation experience) and state-like variables (momentary affect, happiness, and situation perception) account for variance in self-reported behavioral states of the Big Six. In Study 1, we reanalyzed data from Sherman, Rauthmann, Brown, Serfass, and Jones (2015) and found that situation perception explained variance in self-reported behavior in logically coherent ways, but only after considering happiness as an additional predictor. These results were replicated in preregistered Study 2, in which positive and negative affect were additionally assessed as distinct variables. Based on both studies, we conclude that personality traits, affect, and situation perception contribute uniquely to the explanation of self-reported behavior in daily life. Importantly, situation perceptions and affect do overlap, but they are neither the same nor redundant with each other. Indeed, theoretically justified and logically coherent links between situation perceptions and behavioral states remain intact once affect is controlled for, while the links not predicted by theory disappear. These results have implications for personality theories as well as appraisal theories of emotion. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
