Working memory used for a goal-directed behavior has limited capacity. In this article, we examined what the specific function of the working memory capacity as the controlled attention function was. In addition, we discussed how working memory capacity affected the everyday situations in terms of the mind wandering. In the study using event-related potential (ERP), the analysis examined relationship between individual difference in working memory capacity and ERP component involved mind wandering. The amplitude of ERP component involved mind wandering for low-span group has smaller than high-span group. This result suggested possibility that many mind wandering occurred in low-span group during the tasks. Finally, we discussed further research and educational aspect based on the relationship between working memory capacity and attention.
