Creativity Research Journal, Vol. 3, No. 1, 22-32. Abstract A field experiment was conducted to examine the mediating effect of individual creative problem-solving style on the impact of training in creative thinking. This intensive hands-on training emphasized a specific three-phase process which synchronizes divergence and convergence in problem- finding, problem-solving, and implementation. Two attitudes associated with divergent thinking were measured before and after training. The sample was comprised of a mixture of organizational members representing both managers ( n = 90) and non-managers ( n = 66) and a variety of functional specialities, hierarchical levels, and types of business organizations. The most significant finding was that the optimizer style of creative problem-solving improved more that the other three styles ( generator, conceptualizer, and implementor) on measures of both creative thinking attitudes.     Copyright, 2007 Basadur Applied Creativity Inc.
