Although biased attention to emotional stimuli is considered a vulnerability factor for anxiety and dysphoria, research has infrequently related such attentional biases to dimensional models of vulnerability for anxiety and mood disorders. In two studies (Study 1, n = 64; Study 2, n = 168), we evaluate the differential associations of general negative affectivity, anxiety, and dysphoria with biases in selective attention among nonclinical participants selected to vary in both anxiety and dysphoria. Across both studies, preferential processing of angry faces at a 300-ms exposure duration was associated with a general tendency to experience a range of negative affect, rather than being specific to symptoms of either anxiety or dysphoria. In the second study, we found evidence of a suppressor relationship between anxiety and dysphoria in the prediction of delayed attentional biases (1,000 ms) for sad faces. In particular, dysphoria was specifically associated with biased attention toward sad cues, but only after statistically accounting for anxiety; by contrast, anxiety was specifically associated with attentional avoidance of sad cues, but only after statistically accounting for dysphoria. These results suggest that the specificity of relationships between components of negative affectivity and attention to emotional stimuli varies as a function of the time course at which attentional biases are assessed, highlighting the importance of evaluating both anxiety and dysphoria in research on attentional processing of emotional stimuli.

While motivation to pursue goals is often assumed to be a trait-like characteristic, it is influenced by a variety of situational factors. In particular, recent experiences of success or failure, as well as cognitive responses to these outcomes, may shape subsequent willingness to expend effort for future rewards. To date, however, these effects have not been explicitly tested. In the present study, 131 healthy individuals received either failure or success feedback on a cognitive task. They were then instructed to either ruminate or distract themselves from their emotions. Finally, they completed the Effort Expenditure for Rewards Task, a laboratory measure of reward motivation. Results indicate that participants who received failure feedback relied more strongly on the reward magnitude when choosing whether to exert greater effort to obtain larger rewards, though this effect only held under conditions of significant uncertainty about whether the effort would be rewarded. Further, participants with high levels of trait inhibition were less responsive to reward value and probability when choosing whether to expend greater effort, results that echo past studies of effort-based decision-making in psychological disorders. 相似文献

The relevance of recent developments in classical conditioning to understanding the etiology and maintenance of anxiety disorders 总被引:1,自引:0,他引:1
Current etiological models of anxiety disorders emphasize both internal diatheses, or risk factors, and external stressors as important in the development and maintenance of clinical anxiety. Although considerable evidence suggests personality, genetic, and environmental variables are important to these diathesis-stress interactions, this general approach could be greatly enriched by incorporating recent developments in experimental research on fear and anxiety learning. In this article, we attempt to integrate the experimental literature on fear/anxiety learning and the psychopathology literature on clinical anxiety, identify areas of inconsistency, and recommend directions for future research. First, we provide an overview of contemporary models of anxiety disorders involving fear/anxiety learning. Next, we review the literature on individual differences in associative learning among anxious and non-anxious individuals. We also examine additional possible sources of individual differences in the learning of both fear and anxiety, and indicate where possible parallels may be drawn. Finally, we discuss recent developments in basic experimental research on fear conditioning and anxiety, with particular attention to research on contextual learning, and indicate the relevance of these findings to anxiety disorders. 相似文献

ABSTRACT A fundamental aspect of Hans Eysenck's research was his emphasis upon using all the tools available to the researcher to study personality. This included correlational, experimental, physiological, and genetic approaches. Fifty years after Cronbach's call for the reunification of the two disciplines of psychology ( Cronbach, 1957 ) and 40 years after Eysenck's plea for experimental approaches to personality research ( H. J. Eysenck, 1966 ), what is the status of the unification? Should personality researchers use experimental techniques? Do experimental techniques allow us to tease out causality, and are we communicating the advantages of combining experimental with multivariate correlational techniques? We review the progress made since Cronbach's and Eysenck's original papers and suggest that although it is still uncommon to find experimental studies of personality, psychology would benefit from the joint use of correlational and experimental approaches. 相似文献
