Achievements in various fields of creativity are more and more coming from collaborative teams. In this research we investigated the role of interpersonal process variables, namely closeness and perspective taking in group creativity with a two by two experimental design. Sixty-one three person groups assigned to four conditions (1-closeness and perspective taking, 2-perspective taking, 3-no closeness and no perspective taking, 4closeness). Group members collaboratively wrote stories that were rated by three independent expert judges. There was a positive main effect of closeness and negative main effect of perspective taking on group creativity scores. Moreover, the significant interaction between perspective taking and closeness displayed that combination of closeness with perspective taking negatively affect group creativity. These results indicate that closeness might be beneficial for group creativity only when it is not accompanied with perspective taking.

With advances in research environments and the accompanying increase in the complexity of research projects, the range of skills required to carry out research calls for an increase in interdisciplinary and collaborative work. CogNovo, a doctoral training program for 25 PhD students, provided a unique opportunity to observe and analyze collaborative processes. We propose a process-oriented framework for understanding research collaborations along two dimensions: interpersonal and project-related. To illustrate the utility of this process-oriented framework, we apply the framework matrix to several collaborations that emerged within the CogNovo program. The framework that we introduce has several advantages over existing metrics. Firstly, we offer a process-oriented-as opposed to product-oriented-evaluation of interdisciplinary and collaborative endeavors. Secondly, we propose a means of assessment that preserves the distinctive profile (or "fingerprint") of a given collaborative project, thus capturing the uniqueness of each project and its environment.
