Abstract

The effect of warning regarding detection of malingering on the Rey Auditory Verbal Learning Test (RAVLT) was examined in this study. Sixty undergraduate students were randomly assigned to one of four conditions: malingerers, malingerers-with-warnings, warning-only, and control. An incentive that appeared differential, but was an actual constant reward, was offered to participants who could fake in a believable manner (for those in malingering conditions), or to those who performed to the best of their ability (non-malingering conditions). It was predicted that warning participants about the possibility that faking could be detected would modify the behaviour of malingerers, but not those instructed to perform to the best of their ability. Warning had no effect on behaviour in either condition, which was consistent with expectations for the warning-only group, but not for the malingering group. Results are discussed in terms of the ethical and legal issues associated with malingering in neuropsychological practice.
