According to the Attentional Control Theory, individuals with high levels of anxiety often shift their attention inefficiently due to increased effort to meet task demands. However, literature on the effects of anxiety on shifting performance is discrepant. This study examined the impacts of trait and state anxiety on attentional shifting and whether worry or depression explained variance in shifting. One-hundred thirty-eight undergraduate psychology students were randomized to the Trier Social Stress Test (TSST) or control TSST. Subjects completed measures of state/trait anxiety, worry, and depression and a computerized attention task. Statistical analyses included linear mixed modelling (LMM), t-tests, and ANOVAs. Results revealed significant effects of state and trait anxiety and worry, but not depression. Type (location/direction) and presentation (switch/repeat) of trials also affected response times. Trait anxiety significantly related to trial presentation but did not interact with trial type. State anxiety did not significantly relate to either trial index. State and trait anxiety significantly impacted overall response time. Results revealed variations in cognitive flexibility, but no interactions between state and trait anxiety in predicting task switching. These findings are discussed in the context of Attentional Control Theory and relevant empirical research.
