Abstract:
Objective:To explore the roles of cognition and deception in the Guilty Knowledge Tests and its effectiveness on the judgement of the guilt and the informed innocent people.Methods:72 healthy undergraduates participated in the study and were randomly assigned to the experimental conditions.This research was composed of one laboratory experiment with the mork crime paradigm in GKT, and the widely measured electrodermal responses(EDRs) as the physiological index.Three response modes were designed in the experiment in order to test the existence of cognition and deception components.Results:Significant differences of judgement scores were observed in different reponse modes and different roles.Conclusion:Deception plays a more important role than cognition in GKT.However, GKT can not efficiently discriminate the guilty and informed innocent people and needs futher exploration.
