Predicting others’ actions from their Social Contexts

According to predictive process accounts of perception, we identify others’ actions by rapidly forming and updating hypotheses about them as they unfold. Recent work has shown that non-kinematic cues, such as others’ affordances and intentions, inform our action predictions. We sought to explore whether others’ social contexts also guide our predictions for them. Across four experiments, we showed participants videos of an actor walking toward pieces of furniture either with (joint condition) or without (solo condition) a partner standing by the object. Participants indicated the last-seen location of the actor using a touch response, with displacement between joint and solo conditions indicating relative predictive bias toward the end of the actor’s trajectory. We found that responses were more predictive for joint videos but not when we instructed participants that actors would perform an action that did not require a partner. Results imply that others’ social contexts indeed guide our predictions for them.
