The insightful problem-solving process has been proposed to involve three main phases: an initial representation phase, in which the solver inappropriately represents the problem; an initial search through the faulty problem space that may lead to impasse; and a postimpasse restructuring phase. Some theories propose that the restructuring phase involves controlled search processes, whereas other theories propose that restructuring is achieved through the automatic redistribution of activation in long-term memory. In this study, we used correlations between working memory (WM) span measures and problem-solving success to test the predictions of these different theories. One group of participants received a set of insight problems that allowed for a large initial faulty search space, whereas another group received a matched set that constrained the initial faulty search space in order to isolate the restructuring phase of the insightful process. The results suggest that increased ability to control attention (as measured by WM span tasks) predicts an individual's ability to successfully solve problems that involve both the initial search phase and the restructuring phase. However, individual differences in ability to control attention do not predict success on problems that isolate the restructuring phase. These results are interpreted as supporting an automatic-redistribution-of-activation account of restructuring.
