Behavioral correlates of deception in a simulated police interview

Nonverbal indicators of deception in a simulated police interview were examined, particularly the relationship between arm and hand movements and deception, an area in which conflicting results have previously been found. Therefore, in this study, I adopted a more detailed scoring system of arm and hand movements and introduced a baseline interview. Results showed a decrease in subtle hand and finger movements during deception, and thus strongly supported the assumption that subjects try to control their behavior during deception but that this attempted control is only partly successful.
