{"pk":27841,"title":"An Adaptive Signal Detection Model Applied to Perceptual Learning","subtitle":null,"abstract":"We introduce a new model of adaptive criterion setting withina signal detection framework, and show how this provides psy-chological insights that allow us to segregate causes of subop-timality in perceptual learning. We apply this to a perceptuallearning task for both neurotypical and autistic participants.The model parameters provide a bridge between the mecha-nisms of an aberrant precision account of autism and result-ing behavior that can be interpreted within a receiver operatingcharacteristic framework. The model makes superior out-of-sample predictions compared to standard signal detection the-ory, about how people adapt to different environmental manip-ulations when asked to categorize audio-spatial stimuli. Wefind that accuracy of participants is more strongly correlated tothe construct of persistence signals that inhibit response flexi-bility, than to the neuromodulatory gain. We also find evidencefor individual differences in persistence that are correlated toscores on the autistic traits questionnaire.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Adaptive signal detection"},{"word":"Autism"},{"word":"Cognitive model"},{"word":"Categorization"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/4mr7m327","frozenauthors":[{"first_name":"Percy","middle_name":"K","last_name":"Mistry","name_suffix":"","institution":"UC Irvine","department":""},{"first_name":"Joshua","middle_name":"","last_name":"Skewes","name_suffix":"","institution":"Aarhus University","department":""},{"first_name":"Michael","middle_name":"D","last_name":"Lee","name_suffix":"","institution":"UC Irvine","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27841/galley/17480/download/"}]}
