In recent years, there has been a resurgence of interest in the notion of shared cognition and team mental models (Klimoski & Mohammed, 1994). While a number of techniques have been developed to measure mental model similarity dyadically, team mental model measurement has eluded researchers. This presents a problem for the evolution of the team mental model concept in psychology and the establishment of its validity, for example, as a predictor of team performance. The primary aim of this paper is to describe the application of randomization tests as a new method for measuring mental model similarity at the team-level, that is the measurement of team mental models.
