以124名大学生为被试，采用经验抽样的方法，通过复杂记忆广度任务的预测试，考察了工作记忆容量（WMC）与日常生活中的走神经历之间的关系。在7天的时间里，个人数字助理每天向受试者发出8次信号，要求他们立即报告他们的想法是否偏离了他们当前的活动，并描述他们的心理和身体背景。WMC调节了走神与活动认知需求之间的关系。在需要集中注意力和努力的挑战性活动中，高WMC受试者比低WMC受试者更好地保持任务思维，更少走神。因此，研究结果与WMC强调执行注意和控制过程在决定个体差异及其认知后果中的作用的理论是一致的。
An experience-sampling study of 124 undergraduates, pretested on complex memory-span tasks, examined the relation between working memory capacity (WMC) and the experience of mind wandering in daily life. Over 7 days, personal digital assistants signaled subjects eight times daily to report immediately whether their thoughts had wandered from their current activity, and to describe their psychological and physical context. WMC moderated the relation between mind wandering and activities' cognitive demand. During challenging activities requiring concentration and effort, higher-WMC subjects maintained on-task thoughts better, and mind-wandered less, than did lower-WMC subjects. The results were therefore consistent with theories of WMC emphasizing the role of executive attention and control processes in determining individual differences and their cognitive consequences.
