Restructuring revisited

Abstract

The Gestalt psychologists proposed that restructuring ( Umstrukturierung ) is an essential process in thinking. This concept has not been integrated into the information processing theory of problem solving. As a preparation for such an integration, the Gestalt writings about restructuring in problem solving are summarized in a set of principles. Critical scrutiny shows that some Gestalt principles are overstated; others have very weak empirical support. But the psychological reality of restructuring is not in doubt, in spite of the recent criticism by Weisberg and Alba (1982 a ). A unified theory of thinking should interpret restructuring in information processing terms, and explain the relation between restructuring and search.
