Relationship of Speech Activity to Subjective Ratings and Performance during a Convergent Creative Problem Solving Task Involving Communication Among Three People

We aim to develop a support system for creative problem solving during group communication. In this study, we focused on convergent thinking phase in creative problem solving involving group communication. We measured speech activity, subjective ratings, and task performance during a convergent problem-solving task done by three people, and we evaluated the relationships. The results were that the standard deviation of speech duration was significantly inversely correlated with improvements in task score during group communication. Therefore, equilibration of speech activity among participants in group communication would help us to improve the performance of creative problem solving.
