In this study two potential indices of malingering derived from the Rey Auditory Verbal Learning Test (RAVLT) were evaluated as a means of detecting malingering. These were indices based on discrepancies between recognition-recall scores and differences in the serial position effect (SPE). Sixty undergraduate students were randomly assigned to one of four conditions: malingerers, malingerers-with-warning, warning-only, and control. Incentives were offered to participants in all conditions to encourage faking in a believable manner (malingering conditions), or to encourage optimal performance (nonmalingering conditions). Two predictions were made. First, it was predicted that the serial position curve for subjects in malingering conditions would show suppression of primacy effects relative to nonmalingerers. Second, it was predicted that recall would be better than recognition for subjects in malingering conditions compared to nonmalingering conditions. The utility of these indices was also explored in the context of providing subjects' with warnings regarding use of methods to detect malingering. Results indicated that both indices failed to reliably differentiate between malingerers and nonmalingerers, and warnings failed to modify participants' behaviour.

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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
