{"pk":28599,"title":"Partitioning the Perception of Physical and Social Events Within a UnifiedPsychological Space","subtitle":null,"abstract":"Humans demonstrate remarkable abilities to perceive physi-cal and social events based on very limited information (e.g.,movements of a few simple geometric shapes). However, thecomputational mechanisms underlying intuitive physics andsocial perception remain unclear. In an effort to identify thekey computational components, we propose a unified psycho-logical space that reveals the partition between the perceptionof physical events involving inanimate objects and the percep-tion of social events involving human interactions with otheragents. This unified space consists of two prominent dimen-sions: an intuitive sense of whether physical laws are obeyedor violated; and an impression of whether an agent possessesintentions, as inferred from movements. We adopt a physicsengine and a deep reinforcement learning model to synthe-size a rich set of motion patterns. In two experiments, humanjudgments were used to demonstrate that the constructed psy-chological space successfully partitions human perception ofphysical versus social events.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"social perception; intuitive physics; intention;deep reinforcement learning"},{"word":"Heider-Simmel animations"}],"section":"Papers with Oral Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/8gw068jj","frozenauthors":[{"first_name":"Tianmin","middle_name":"","last_name":"Shu","name_suffix":"","institution":"University of California, Los Angeles","department":""},{"first_name":"Yujia","middle_name":"","last_name":"Peng","name_suffix":"","institution":"University of California, Los Angeles","department":""},{"first_name":"Hongjing","middle_name":"","last_name":"Lu","name_suffix":"","institution":"University of California, Los Angeles","department":""},{"first_name":"Song-Chun","middle_name":"","last_name":"Zhu","name_suffix":"","institution":"University of California, Los Angeles","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28599/galley/18470/download/"}]}
