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 (EPQ-R; STAI; Marlowe-Crowne Social Desirability Scale)
IntroductionA more recent line of research is concerned with the biasing effects of anxiety on cognitive processes, leading to enhanced awareness of threat (see Eysenck, 2006). It is now commonplace to relate anxiety to the attentional resources and working memory (e.g., Eysenck, Derakshan, Santos & Calvo, 2007). However, cognitive psychological accounts of anxiety are not necessarily conclusive and consistent (see Fajkowska & Krejtz, 2007, for a review). We have suggested that promising as an approach to better understanding cognitive functioning in anxiety is to study a group of trait anxious individuals as heterogeneous. Recent research from a number of fields led us to believe, that the heterogeneity of high-anxious group is mainly formed by differentiation in individual properties related to effort and arousal (e.g., Fajkowska & Krejtz, 2006;2007) and by differentiation in style of coping (e.g., Weinberger, Schwartz & Davidson, 1979;Asendorpf & Scherer, 1983;Eysenck, 2000;2006).The purpose of this article is to describe within the frame of the attentional control theory an initial study, which tested the hypothesis that anxious individuals process facial threat and other facial emotional stimuli in a manner associated with their style of coping and the level of extraversion, neuroticism and psychoticism.The attentional control theory is an approach to anxiety and cognition representing a major development of Eysenck (1979) and Eysenck and Calvo's (1992) processing efficiency theory. The central focus of the processing efficiency theory was on a distinction between effectiveness and efficiency. Effectiveness refers to the quality of task performance, which is conventionally assessed by various behavioural measures (e.g., speed of performance; accuracy of performance). In contrast, efficiency refers to the relationship between the effectiveness of performance and the effort or processing resources invested in that performance. According to the theory, anxiety generally impairs processing efficiency on complex tasks to a greater extent than performance effectiveness.The original processing efficiency theory rested on two major assumptions. First, worry is the component of state anxiety responsible for effects of anxiety on performance effectiveness and efficiency. Worry or self-preoccupation is characterised by concerns over evaluation and failure and
