{"pk":29203,"title":"The reassurance of the Complex Trial Protocol against ecologically validatedcountermeasures","subtitle":null,"abstract":"The P300-based Complex Trial Protocol (CTP), developed by Rosenfeld et al. (2008), is known to compensate for accuracydegradation and countermeasure issues of the Concealed Information Test. Although a myriad of CTP studies usingelectroencephalogram has been investigated, the lack of crime-related details and the complexity of the previously usedcountermeasures have revealed the necessity of in-depth experiment. In the present study, fifty participants were dividedinto three groups: guilty, innocent, and guilty-countermeasure. Participants engaged in a mock-crime scenario and onlythe guilty-countermeasure group performed ecologically validated countermeasures during the CTP. Participants reactiontime and the amplitude of P300 components of event-related potential were analyzed and there was a significant difference(p¡0.05). Moreover, using the bootstrapping method, participants were correctly classified as guilty or innocent, regardlessof the use of countermeasure, with accuracy above 80%. The results support the possibility of the on-site usage of theCTP.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5vz5n6kb","frozenauthors":[{"first_name":"Hyemin","middle_name":"","last_name":"Kim","name_suffix":"","institution":"Korea 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/29203/galley/19074/download/"}]}
