Working Memory and Expertise

The question of what individual differences in working memory capacity reflect has been a topic of intensive interest in research for several decades. This research has shed light on mechanisms underlying working memory performance. At the same time, the chapter authors argue this research has been myopic in two respects. First, it has largely ignored the influence of other predictor variables on complex task performance. Second, it has overlooked the importance of the environment as a co-determinant of performance. In this chapter, answering the seven questions put to contributors of this volume, the authors discuss their own research on working memory capacity and describe an ecological view of the working memory system that they believe will advance both research on working memory and the usefulness of findings from this research.
