Thesis (M.A.)--California State University, Fullerton, 2011.

Detecting deception by human judges is generally poor, usually not greater than chance levels. This study is based on the idea that lying requires a great deal of available cognitive resources, mainly inhibition. Inhibition is part of the mental executive management system used to suppress task-irrelevant information for the efficient processing of online tasks. The current study utilized a repeated questioning method hypothesized to increase cognitive load by undermining inhibitory processes. In Experiment 1 undergraduate students were interviewed about two autobiographical events and repeatedly switched between lying and telling the truth during two sessions. Participants in the truth condition told the truth about both events. Participants in the deception condition lied about one of the events. In the initial interview session, participants discussed one event then the other. Participants discussed those events a second time in an unexpected repeated session. Working memory capacity (WMC) was measured to assess lying performance as a function of senders' cognitive capacity. Liars experienced high cognitive load during the repeated questioning interviews, especially those with low WMC. Receivers in Experiment 2 viewed video clips of Experiment 1 interviews and assessed whether senders were lying or telling the truth. Receivers' true-lie discrimination was significantly better in the repeated condition than the control condition. Senders' WMC also affected receivers' judgments. These results confirm the hypothesis that undermining inhibitory processes increases cognitive load and improves lie detection. This suggests that the theory-based procedure used in this study has a potential use in applied settings where lie detection is crucial.
