This paper investigates the relationship between interaction behaviors and the cognitive characteristics of participating individuals in engineering design teams engaged in concept generation. Individual characteristics are measured using the Kirton Adaption Innovation inventory, which assesses cognitive preference for seeking and responding to change. Team interactions are measured using the Interaction Dynamics Notation, which allows for interaction behavior to be quantitatively analyzed. A correlation analysis reveals statistically significant correlation between individual characteristics and specific interaction behaviors. A sequence analysis of the team data also reveals specific interaction sequences associated with a greater probability of idea occurrence in team interaction. These findings could be taken as a first step towards building a cognitive-behavioral model of engineering design team performance.
