Abstract This study simulated group interaction situations with animated depictions, and used perceptual cues (spatial proximity and synchronous movements) to manipulate social group information, in order to explore whether and how people can establish expectation for the behavior according to social group information. The results showed that: (1) Comparing to the inconsistent condition (i.e., the directivity of action or action means of the predicted agent was different from other agents’), participants responsed faster in the consistent condition, in which the directivity of action (Experiment 1a) or action means (Experiment 2a) of the predicted agent was consistent with other agents’, when all agents belonged to the same social group . (2) When the social group information was eliminated (i.e., the members moved solely and spaced at interval in Experiment 1b & Experiment 2b) or the predicted agent belonged to a different group as two members for demonstrating actions, there was no significant difference of response time between consistent and inconsistent conditions. On the basis of these results, we suggest that observers can make action prediction for group members based on the social group information formed by the perceptual cues, and they expect that the members of social groups should act consistently.
