This experiment assessed the components of Baddeley's working memory system impaired by anxiety during performance of the Corsi Blocks Test. The Corsi task was performed concurrently with different secondary tasks (i.e., articulatory suppression; counting backwards; spatial tapping; simple tapping). Results showed Corsi performance depended mainly on the central executive and visuospatial sketchpad components of working memory. Adverse effects of trait anxiety on the Corsi task were observed on the central executive but not on the phonological loop or the visuospatial sketchpad. These effects were not mediated by state anxiety. The findings indicate for the first time that trait anxiety impairs central executive functioning on a nonverbal task, and that anxiety does not impair functioning of the “slave” systems (i.e., phonological loop; visuospatial sketchpad). Theoretical implications of these findings are discussed. 相似文献

This article focuses on differences between anxiety and depression. The first study is concerned with the timing (past, present, future) of negative events associated with high levels of anxiety and depression in normal participants. Depression was associated more with past events than future events, whereas the opposite was the case with anxiety. These findings are consistent with those reported in several studies on clinical samples. In a second study, participants provided their emotional reactions to scenarios referring to negative events lying in the past or in the future with the future events being either uncertain or probable. Past events were associated with more depression and less anxiety than future events whether uncertain or probable. Probable future events were associated with more anxiety and depression than uncertain ones. Theoretical implications of these findings are discussed. 相似文献
