ABSTRACT
This chapter examines the extent to which non verbal behaviour can reveal feelings which we are motivated to conceal Three broad issues are examined. Firstly, the literature concerning non verbal cues, both actual and assumed which accompany deceit, is discussed. Secondly, the question of whether deception can in fact be detected from such non verbal cues is examined and finally, factors influencing both the ability to conceal deception and detect deception accurately are evaluated. The chapter concludes with the assertion that there is little evidence for a link between certain non verbal behaviours and detection of deception. However, much research to date has been conducted with undergraduate students and the next step must be to pursue more ecologically valid research.
