An integrated perspective on insight.

The present study on insight is based on an integration of Kaplan and Simon's (1990) information processing theory of insight, a cognitive style theory, and achievement motivation theory. The style theory is the Assimilator (rule oriented, familiarity seeking)-Explorer (novelty seeking, explorative) styles (Kaufmann, 1979). Our hypothesis is that the effectiveness of 2 types of search constraints (prior experience and solution hints) for solving insight problems is moderated by both cognitive style and achievement needs, and depending on optimal levels of achievement motivation for different task conditions. We tested the hypothesis in a randomized experiment in which 3 levels of achievement needs and 1 type of search constraint (solution hints were available or not available) were experimentally manipulated. In addition, participants completed a cognitive style test, a measure of prior problem-solving experience (the second type of search constraint), and controls for intelligence. There were 476 participants (the mean age was 18.4 years). Results revealed 2 similar and significant 3-way interactions between styles, achievement needs, and the 2 types of search constraints. The pattern of interaction supported the idea that stylistic competence for the task characteristics (with and without search constraints available), when combined with manipulated achievement needs, predicted performance in counterintuitive ways but in line with the classic achievement motivation theory. With appropriate stylistic competence for the task characteristics elevated achievement needs led to poorer performance. With less appropriate stylistic competence, performance improved with increasing motivation. Implications for information processing theory are discussed. (PsycINFO Database Record
