Perceptual causality and animacy

Certain simple Visual displays consisting of moving 2-D geometric:shapes tan give rise to percepts with: high-level properties such as causality-and animacy. This article reviews recent research on such phenomena, which began with the classic work of Michotte and of Heider and Simmel, The importance of such phenomena stems in part from the fact : that these interpretations seem to be largely perceptual in nature - to be fairly fast, automatic irresistible and highly stimulus driven - despite the fact that they involve impressions typically associated with higher-level cognitive processing. This research suggests that just as the visual system works to recover the physical structure of the world by inferring properties such as 3-D shape, so too does it work to recover the causal : and social structure of the world by inferring: properties such as causality and animacy.
