{"pk":28059,"title":"Physical and Causal Judgments for Object CollisionsDepend on Relative Motion","subtitle":null,"abstract":"Human judgments about the physical attributes of—and causalrelationship between—two colliding objects have been stud-ied extensively over the past seventy years. Recent computa-tional evidence suggests that judgments about the mass ratioof two colliding objects, as well as their perceived causal re-lation, can be explained by a coherent framework based on aNewtonian physical model and probabilistic inference result-ing from noisy observations of object movements. However,it remains unclear how the physical and causal reasoning sys-tems interact with the motion perception system when formingthese judgments. The current study aims to examine whetherhigh-level judgments are guided by object motion representedas relative motion with reference to a moving background, oras absolute motion with reference to a stationary position inthe world. Both experimental evidence and model simulationresults support the notion that physical and causal inference inobject collisions depend on relative motion rather than abso-lute motion.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Intuitive physics; causality; mass judgment; refer-ence frame; Bayesian inference"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9fx081fw","frozenauthors":[{"first_name":"James","middle_name":"R","last_name":"Kubricht","name_suffix":"","institution":"UCLA","department":""},{"first_name":"Hongjing","middle_name":"","last_name":"Lu","name_suffix":"","institution":"UCLA","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T23:30:00+05:30","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28059/galley/17698/download/"}]}
