• Perceivers spontaneously infer information about people from their behavior.• We proposed that perceivers infer others' social roles from their behaviors.• Three studies documented spontaneous role inferences (SRIs).• SRIs were cognitively efficient, forming under cognitive load.• SRIs had downstream consequences for trait impressions of targets. a b s t r a c t a r t i c l e i n f o Past research has demonstrated that perceivers spontaneously infer individuals' goals, beliefs, and traits from their behaviors. These inferences processes are essential for predicting others' future behaviors and, thus, for smooth social interaction. Given that social roles (e.g., professor, mother) are also predictive of an individual's future behaviors, we proposed that perceivers spontaneously infer individuals' social roles from their behaviors. Across three experiments, including two different paradigms, we documented that perceivers formed spontaneous role inferences (SRIs) from single behaviors. SRIs occurred unintentionally, efficiently, and had important downstream consequences for impression formation. Namely, SRIs led perceivers to rate targets as higher on role-consistent traits. Together, these findings provide the first empirical demonstration of a novel process in impression formation.Published by Elsevier Inc.
Spontaneous social role inferencesOne of the earliest questions asked by social psychologists was: how do perceivers distill knowledge of another person from his or her behaviors? Humans have an unparalleled ability to extract valuable social information, such as intentions and dispositions, from the mere observation of another person's behavior. Given that others' social roles also provide important information about their intentions and future behaviors, we propose that perceivers also readily infer individuals' social roles from their behaviors.
