Creative thinking and problem solving do not necessarily come naturally to people. In the case of individuals, there are blocks to creative thinking and creative problem solving. Executives may have learned from past experience that a particular way of dealing with a problem usually leads to a satisfactory solution. Constant successful application of the approach reinforces the belief that this is the correct way to approach the problem, and even the only way to approach the problem. Personality appears to influence how people process information. In the past there have been concerted efforts to define dimensions of personality and to develop measurement tools to relate how people are influenced in processing information according to their predisposition on these dimensions. Learning styles present another perspective from which to understand how people may approach the process of creative thinking. Individual moods and emotions can impact on the ability of team members to participate constructively in the creative problem solving process.
