根据焦虑的注意控制理论（Eysenck, Derakshan, Santos, & Calvo, 2007），焦虑会损害涉及工作记忆转移功能的认知任务的表现。这一假设使用混合反扫视范式进行了检验，在该范式中，参与者执行了单任务和混合任务版本。在单一任务中，参与者分别完成反和进程试验，而在混合任务中，参与者以随机顺序完成反和进程试验。转换成本的分析表明，高焦虑个体并没有表现出通常报道的眼跳潜伏期的矛盾改善，而低焦虑个体却有。研究结果在注意控制理论的框架内进行了讨论。
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.
