The Impact of Environmental Clues in Problem Solving and Incubation: The Moderating Effect of Ability

ABSTRACT: When a problem is abandoned, a solution may subsequently and unexpectedly emerge. The intervening period, known as incubation, has sometimes been ascribed to opportunity assimilation. According to this theory, impasses to a problem create failure indexes, which ensure that random clues in the environment are detected and utilized. To assess the notion that failure indexes enhance clue utilization, 50 participants undertook a series of word problems. After this initial attempt, the participants were deceived and told that half the unsolved problems were insoluble. A series of general knowledge questions was then presented; the answers to the original problems were surreptitiously incorporated within this questionnaire. The instruction that certain problems were insoluble was retracted, and the items that had yet to be solved were reinstated. High-ability problem solvers were less likely to correctly answer the items that were designated as insoluble. Low-ability problem solvers, however, generated the reverse pattern. A model that links failure indexes to the forgetting of suboptimal strategies was formulated to accommodate these findings.
