Personality and Cognitive Performance The two experiments reported here are concerned with the influence of trait anxiety and other individual differences on cognitive performance using the face-in-the-crowd procedure. Participants completed questionnaires and across two experiments searched for discrepant faces in matrices of otherwise identical faces. The key findings from this study indicated that anxiety enhanced processing efficiency of positive emotional material when interacts with high psychoticism. Additionally, the vigilance for threatening and neutral faces was a characteristic of sanguine individuals with (...) repressive coping while inefficient processing of threatening and neutral stimuli of non-defensive melancholic subjects. These results are discussed with reference to attentional control theory. (shrink)
