Abstract

It has been argued that a worker's ability to overcome interruptions depends on his or her level of expertise in the interrupted main task. The effects of repetitive practice (repeated experience) with new task have not been systematically analyzed. This paper reviews practice effects as reported from interruption experiments. The theory of long-term working memory (Ericsson & Kintsch, 1995) predicts that repetitive practice (experience) does not by itself lead to those changes in the structure of a novel memory-demanding task that are necessary for resisting interference. The review supports this prediction but also uncovers conditions in which repetitive practice produces a benefit, albeit limited, for interruption tolerance.
