Abstract: | The ability to flexibly switch attention between emotional and non-emotional information in working memory is considered important in stress-resilience and is impaired in mood disorders. A recent theory claims that this component of attention is specifically related to ruminative thought. To further investigate this claim we report two new experiments using the internal shift task (IST). In Experiment 1 (N = 27) we examined the stability of switching ability measured using the IST through examination of internal consistency (stability within the task) and test–retest-reliability (stability over time) over two weeks. Results indicate relatively high stability of switching ability measured with the IST. In Experiment 2 the IST was administered to a pre-selected undergraduate sample of high (N = 20) and low ruminators (N = 20). The main findings were that rumination was related to attentional switching impairments, specifically in the context of emotional information. The switching impairments were most pronounced when negative information was held in working memory. The attentional switching impairments were most strongly related to the depressive brooding component of rumination. The results of this study lend further support to the proposed link between rumination and switching abilities. |
