The effects of threat on task-switching in anxiety: evidence from eye-movements during an antisaccade task
Derakhshan, Nazanin and Ansari, T.L. (2008) The effects of threat on task-switching in anxiety: evidence from eye-movements during an antisaccade task. Psychophysiology 45 (S1), S39-S39. ISSN 0048-5772.
According to the attentional control theory of anxiety (Eysenck, Derakshan, Santos, & Calvo, 2007), anxiety impairs performance on cognitive tasks that involve the shifting function of working memory. This hypothesis was tested using a mixed antisaccade paradigm, in which participants performed single-task and mixed-task versions of the paradigm. The single task involved the completion of separate blocks of anti- and prosaccade trials, whereas in the mixed task, participants completed anti- and prosaccade trials in a random order within blocks. Analysis of switch costs showed that high-anxious individuals did not exhibit the commonly reported paradoxical improvement in saccade latency, whereas low-anxious individuals did. The findings are discussed within the framework of attentional control theory.
