Previous research has shown that Stroop effects interact with working memory capacity (WMC) more strongly with lists of mostly congruent items. Although the predominant explanation for this relationship is goal maintenance, some research has challenged whether listwide effects truly reflect goal-maintenance abilities. The current study improved upon previous methodology by using both within-subject and between-subjects manipulations of goal reminder, increasing both the number of trials between reminders and the total length of the task to allow for greater goal neglect, and more precisely maintaining congruency proportion within each block. Participants completed the Automated Operation Span followed by a Stroop task in which they stopped every 24 trials to vocalize either a goal-reminder statement ("name the color not the word") or a nongoal statement ("This is part of my intro to psychology class"). In the within-subject manipulation (Experiment 1), there was no consistent benefit for goal reminders over nongoal statements. However, in the between-subjects manipulation (Experiment 2), results demonstrated a strong benefit of goal reminders, such that goal reminders eliminated the relation between WMC and Stroop effects, whereas that relation was robust following nongoal statements. Moreover, the benefit of receiving goal reminders lasted for at least 24 trials and accumulated across the course of the experiment. These data provide strong evidence that goal reminders eliminate the relationship between WMC and Stroop errors and suggest goal reminders can be a useful intervention for those suffering from lapses in controlled attention.

先前的研究表明,在主要由一致项目组成的列表中,斯特鲁普效应与工作记忆容量(WMC)的相互作用更强。尽管对这种关系的主要解释是目标维持,但一些研究对列表层面的效应是否真的反映目标维持能力提出了质疑。当前的研究改进了先前的方法,采用了目标提醒的组内和组间操作,增加了提醒之间的试验次数和任务的总长度,以允许更大程度的目标忽视,并更精确地在每个组块内维持一致性比例。参与者完成自动化操作广度任务,然后进行斯特鲁普任务,在该任务中,他们每24次试验停下来说出一个目标提醒语句(“说出颜色而不是单词”)或一个非目标语句(“这是我心理学导论课程的一部分”)。在组内操作(实验1)中,目标提醒并没有比非目标语句带来持续一致的益处。然而,在组间操作(实验2)中,结果表明目标提醒有很大益处,即目标提醒消除了WMC与斯特鲁普效应之间的关系,而非目标语句后这种关系依然显著。此外,接受目标提醒的益处持续了至少24次试验,并在实验过程中不断累积。这些数据提供了有力证据,表明目标提醒消除了WMC与斯特鲁普错误之间的关系,并表明目标提醒对于那些在控制性注意方面出现失误的人可能是一种有用的干预措施。(PsycInfo数据库记录(c)2023美国心理学会,保留所有权利)
