%0 Journal Article %T Toward a Research Agenda for the Study of Situation Perceptions: A Variance Componential Framework %A John Rauthmann %A Ryne Sherman %J Personality and Social Psychology Review %@ 1532-7957 %D 2019 %R 10.1177/1088868318765600 %X Situation perception represents the fulcrum of a ¡°psychology of situations¡± because situation ratings are ubiquitous. However, no systematic research program exists so far, particularly because two competing traditions have not been integrated: Objectivist views stress situations¡¯ consensually shared meanings (social reality), and subjectivist views idiosyncratic meanings (personal reality). A componential framework can disentangle social from personal reality in situation perceptions: When multiple perceivers (P) rate multiple situations (S) on multiple situation characteristics (C), variance in those ratings can be decomposed according to S ¡Á C, P ¡Á S, and P ¡Á C breakdowns. Six grand questions of situation perception research are spawned from these decompositions: complexity, similarity, assimilation, consensus, uniqueness, and accuracy. Analyses of real data are provided to exemplify our ideas, along with customizable R codes for all methods. A componential framework allows novel and unique insights into different questions surrounding situation perceptions and provides a coherent research agenda %K situations %K situation perception %K variance decomposition %K Cronbach¡¯s decomposition %K social relations model %K generalizability theory %U https://journals.sagepub.com/doi/full/10.1177/1088868318765600
