{"pk":26868,"title":"Perceptual contrast and response assimilation in sequential categorization\nwithout feedback","subtitle":null,"abstract":"Sequential categorization of perceptual stimuli typically\nshows contrast from one trial to the next. Using familiar\ncategories of animals and faces, contrast effects were\ndissociated from assimilation effects. Two independent main\neffects were observed: contrast to the preceding stimulus, and\nassimilation to the previous response. It is argued that\ncontrast and assimilation may reflect different processes in\ncategorization.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Categorization"},{"word":"Contrast"},{"word":"assimilation"}],"section":"Talks: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1898h6kt","frozenauthors":[{"first_name":"James","middle_name":"A.","last_name":"Hampton","name_suffix":"","institution":"University of London","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T13:00:00-05:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26868/galley/16504/download/"}]}
