Reaction Time-based Detection of Concealed Information in Relation to Individual Differences in Executive Functioning

摘要

Executive functioning has been shown to play an essential role in a person's ability to accurately and efficiently execute deceptive responses. The present study relates individual differences in executive functions and anxiety to the accuracy and latency of deceptive responses in a reaction time (RT)-based Concealed Information Test with pictorial stimuli extracted from a mock crime scenario. Results indicated that the pictorial RT-based Concealed Information Test successfully differentiated between guilty and innocent participants. In terms of executive functions, set-shifting and inhibition were directly related to deception accuracy and speed, respectively. However, enhanced underlying working memory skills (both verbal and spatial) were associated with longer RTs for item classification. No strong associations were noted with anxiety dimensions. The implications of these findings are discussed in relation to neurocognitive models of deception and to the process of deception detection.
