The present study investigated whether the control of reflective attention in working memory (WM) is impaired in high trait anxiety individuals. We focused on the consequences of refreshing-a simple reflective process of thinking briefly about a just-activated representation in mind-on the subsequent processing of verbal stimuli. Participants performed a selective refreshing task, in which they initially refreshed or read one word from a three-word set, and then refreshed a non-selected item from the initial phrase or read aloud a new word. High trait anxiety individuals exhibited greater latencies when refreshing a word after experiencing the refreshing of a word from the same list of semantic associates. The same pattern was observed for reading a new word after prior refreshing. These findings suggest that high trait anxiety individuals have difficulty resolving interference from active distractors when directing reflective attention towards contents in WM or processing a visually presented word.
本研究调查了高特质焦虑个体在工作记忆(WM)中对反射性注意的控制是否受损。我们关注了刷新——对脑海中刚刚激活的表征进行短暂思考的简单反射过程——对后续言语刺激处理的影响。参与者执行了一项选择性刷新任务,在该任务中,他们最初刷新或阅读三字组中的一个单词,然后刷新初始短语中未选择的项目或大声读出一个新单词。高特质焦虑个体在从同一语义关联列表中刷新一个单词后再刷新另一个单词时,表现出更长的潜伏期。在先前刷新后阅读新单词时也观察到了相同的模式。这些发现表明,高特质焦虑个体在将反射性注意指向工作记忆中的内容或处理视觉呈现的单词时,难以解决来自活跃干扰物的干扰。
