The development of information technology is forcing a reconsideration of the process of idea generation. In this study, a laboratory experiment was conducted to evaluate the effects of the communication mode (computer-mediated and face-to-face) and goal setting (assigned goal and do-your-best) on an idea generation task of between-subjects design. Thirty-two student work groups consisting of three persons were assigned a 15-minute task to generate ideas for unusual uses of certain objects supported by a computer-mediated or face-to-face communication medium. Results show that the computer-mediated groups were more productive and creative than the face-to-face groups, and their members perceived that they had more opportunity to participate and were more motivated in the task. These results might be interpreted as evidence that there occurs little production blocking effect in a computer-mediated idea generation task. Goal setting had little positive effect on performance in CMC condition. The results are discussed in terms of the relation between productivity and creativity and process gain of CMC.
