摘要
这项研究调查了从工作记忆中删除不相关信息的触发因素。基于移除是一个独特的工作记忆更新过程的观点(Ecker et al., 2010),我们假设移除过程在选择任务相关信息后开始。为了验证这一假设,我们采用了一个改进的Sternberg任务,该任务反映了信息删除的时间过程。在该任务的标准程序中,在指导相关信息后,移除过程被认为在大约1500毫秒内完成。如果选择引起移除,当选择需要更多时间时,移除可能不会在1,500 ms内结束。为了增加选择的时间,我们创造了一个高干扰的环境。实验1表明,在引导相关信息后的2000 ms内,去除是不完全的。实验2表明,在较长的时间内可以完成去除。这些结果支持了移除过程的触发因素是选择完成的假设。这与最近关于执行职能的框架是一致的。
[Selection of goal-directed information triggers removal of irrelevant information from working memory].
This study investigated the triggers for removing irrelevant information from working memory. Based on the perspective that removal is a unique process of updating working memory (Ecker et al., 2010), we hypothesized that the removal process begins after selection of task-relevant information. To test this hypothesis, we employed a modified Sternberg task that reflects the time-course for the removal of information. In a standard procedure of this task, the removal process is thought to be completed in approximately 1,500 ms after directing relevant information. If selection induces removal, removal might not end within 1,500 ms when selection requires more time. To increase the time for selection, we created a circumstance with high interference. Experiment 1 showed that removal was incomplete within 2,000 ms after directing relevant information. Experiment 2 showed that removal could be completed given more time. These results support the hypothesis that the trigger for the removal process is the completion of selection. This is in consistent with recent frameworks concerning executive functions.
