在本实验中，我们考察了不同的指令对注意偏向的修正以及随后对担忧持久性的影响。参与者在没有过度担忧的情况下完成了一项修改后的点探测任务，旨在训练人们对威胁或中性词语的注意力。每组的一半被给予关于词价和目标位置之间关系的明确指示，另一半被给予更常见的最低限度的指示。对焦虑持续性的影响通过对一段时间的指导焦虑前后的思维侵扰的价格进行分类来评估。对点探测任务上测试项目的反应延迟表明，注意力被成功地操纵在预期的方向上，并且明确的指示导致了更有效的注意力调节。此外，根据评估员的评级，接受明确指示的参加威胁组的参与者在接受指示的担忧之后报告了明显更多的负面思维干扰，而参加中立组的参与者则没有。这些发现表明，对威胁性信息的注意偏差在担忧持久性中起着作用，而明确的指示可能有助于纠正这种偏差。(C)2009爱思唯尔有限公司。保留所有权利。
In this experiment we investigated the effect of different instructions on the modification of attentional biases, and subsequently on worry persistence. Participants without excessive worry completed a modified dot-probe task, designed to train attention either to threat or neutral words. Half of each group was given explicit instructions regarding the relationship between word valence and target location, and half were given the more usual minimal instructions. Impact on worry persistence was assessed by categorizing the valence of thought intrusions before and after a period of instructed worry. Response latencies to test items on the dot-probe task showed that attention had been successfully manipulated in the expected direction, and explicit instructions led to more effective attention modification. Moreover, participants in the attend-threat group who received explicit instructions reported significantly more negative thought intrusions following instructed worry, as rated by an assessor, whereas participants in the attend-neutral group did not. These findings suggest that an attentional bias towards threatening information plays a role in worry persistence, and that explicit instructions may be helpful in modifying this bias.
