Abstract : Three studies were conducted to investigate questions concerning which type of individual is most susceptible to errors in skilled (highly practiced) cognitive task performance. The first study was a small pilot project conducted with university students. The remaining two studies were larger scale projects conducted with Air Force enlisted personnel. The research findings suggested that self-reported error-proneness is not related to performance in at least one class of cognitive skill tasks or to working memory task performance. Instead, measures of error-proneness appear to reflect how a person perceives themselves or how they wish to present themselves. The research findings also suggested that measures of working memory capacity (i.e., measures of general mental resource availability or mental workspace) were predictive of undetected errors in skilled performance after extensive skill practice. This finding suggests the need for further research as it has potential implications for selection of individuals to critical jobs. This finding also has implications for current theories of individual differences in learning. Finally, the research produced inconsistent findings regarding the relationship of anxiety to cognitive performance errors. i%Iore research is needed to resolve questions in this latter topic area.
