{"pk":31788,"title":"Attenuation of Belief Perserverance In a Covariation Judgement Task","subtitle":null,"abstract":"A wide variety of judgment tasks have shown that\nonce a reasoner favors a hypothesis, encountering\nevidence which contradicts it might not, in and of\nitself, dislodge that hypothesis. T h e interaction of\nprior belief and n e w evidence w a s studied in a\ncovariation judgment task where subjects monitored\nmultiple predictor-outcome relationships. Each\nrelationship w a s programmed to reflect a strong\npositive contingency in a first phase, but in the\nsecond phase the contingency w a s negative,\ndisconfirming the acquired expectation. For two of\nthese relationships, the negative evidence w a s framed\nas positive evidence for alternative relationships,\nwhile in a third relationship, the negative evidence\nw a s not presented as supporting alternative\nexplanations. Subjective contingency estimates\nindicated that the negative contingency w a s\nrecognized in all three conditions. Belief\nperseverance, as measured by the likelihood of\npredicting the outcome on trials where the original\npredictor variable w a s present, w a s the strongest in\nthe condition v^thout alternatives. These results\nsupport the notion that belief change is a function of\nthe negative evidence pertaining to that belief and the\npresence of alternative explanations which seek their\nsupport from that same evidence.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Submitted Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5xj424kb","frozenauthors":[{"first_name":"Frederic","middle_name":"","last_name":"Vallee-Tourangeau","name_suffix":"","institution":"McGill University","department":""},{"first_name":"A.G.","middle_name":"","last_name":"Baker","name_suffix":"","institution":"McGill University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1993-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/31788/galley/22856/download/"}]}
