{"pk":28767,"title":"Orthogonal multi-view three-dimensional object representations in memoryrevealed by serial reproduction","subtitle":null,"abstract":"The internal representations of three dimensional objectswithin visual memory are only partially understood. Previousresearch suggests that 3D object perception is viewpoint de-pendent, and that the visual system stores viewpoint perspec-tives in a biased manner. The aim of this project was to ob-tain detailed estimates of the distributions of 3D object viewsin shared human memory. We devised a novel experimentalparadigm based on transmission chains to investigate memorybiases for the 3D orientation of objects. We found that memorytends to be biased towards orthogonal diagrammatic perspec-tives aligned with the ends of the standard basis for a set ofcommon 3D objects, and that these biases are strongest for sideviews as well as top or bottom views for a small set of bilater-ally symmetric objects. Finally, we found that views sampledfrom the modes were easier to categorize in a recognition task.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Memory; 3D object perception; Serial reproduc-tion; Iterated learning; Vision."}],"section":"Papers with Poster Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9885s6qj","frozenauthors":[{"first_name":"Thomas","middle_name":"A.","last_name":"Langlois","name_suffix":"","institution":"University of California, Berkeley","department":""},{"first_name":"Nori","middle_name":"","last_name":"Jacoby","name_suffix":"","institution":"Max Planck Institute for Empirical Aesthetics","department":""},{"first_name":"Jordan","middle_name":"","last_name":"Suchow","name_suffix":"","institution":"Stevens Institute of Technology","department":""},{"first_name":"Thomas","middle_name":"L.","last_name":"Griffiths","name_suffix":"","institution":"Princeton University","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/28767/galley/18638/download/"}]}
