This study is to apply the theory of concept combination to stimulate imagination and verify that abstractive concepts is stimulated more than non-abstractive concepts. The participants are 180 management college students froma university in central Taiwan. They were randomly assigned to three conditions: abstractive, non-abstractive, and controlled groups. We manipulated concept combination thinking models through discussion course of three groups: 1) Abstractive: with abstractive concept combined with thinking model. 2) Non-abstractive: with concrete concept combined with thinking model. 3) Control: did not utilize concept combination theory. Each group was administered two applied case discussions to simulate participants to associate in cases contexts by concept combination theory. All participants in the three groups were administered the pretest and posttest of imagination. They were all required to complete abusiness plan. Results showed that imagination was stimulated by the thinking model of concept combination. And the imagination score of the abstractive and non-abstractive groups are higher than the control group.
