The present study was part of a research aimed at the development of a method to be applied in the improvement of heuristic problem-solving groups. The purposes of the present study can be resumed in the following three points centered around the problem-solving groups: 1. to develop a method to multidimensionally measure attitude change and `climate cognition' in the problem-solving process. 2. to analyze the conditions in which the problem-solving groups form creative attitudes. 3. to analyze the roles of playing-managers in the problem-solving groups. These three points were discussed with the data of a longitudinal experimental study of heuristic problem-solving groups as a base, and it was proved that intrinsic motivation is an important factor in facilitating the formation of creative attitudes.
