In collective affect research, an assumption is often made that through processes such as emotional contagion and attraction-selection-attrition members will converge unto a shared group affective tone. While this assumption is not without warrant, a limitation of previous work on interpersonal emotional processes of individuals, individuals within dyadic relationships, or members within teams is the lack of examination into the varying perceptions individuals may form regarding these affective experiences. To examine the development and influence of these affective perceptions, we extend recent works from work group conflict literature to examine the influence of perception asymmetry when applied to affective interactions. Wherein, we describe a novel construct of Perception Asymmetry of Affect (PAA). PAA refers to the congruence (e.g.; low level of PAA) or incongruence (e.g.; high level) of perceptions of positive and negative affective experiences between two or more individuals. This paper explores the following questions: 1) does perception asymmetry of affect exist; 2) if so, what causes perception asymmetry between individuals and their groups, within dyads, and within groups. This article contributes to literature on collective affect by offering a detailed framework for an understudied phenomenon of diverging or asymmetric perceptions.
