Temporal Complexity in Team Coordination Associated with Increased Performance in a Fast-Paced Puzzle Task

摘要

Coordination is a critical component of team performance. Nonlinear time-series measures, such asSample Entropy (SEn), provide a novel means to examine temporal structure in team coordination. Thegoal for this study was to apply SEn to the continuous motor responses (gamepad button presses) of dyadicteams who performed a fast-paced puzzle task (Quadra – a variant of videogame Tetris). Inferentialanalyses were used to: a) determine if meaningful (i.e., deterministic) temporal structure existed in teamresponses using SEn, and b) examine correlations between team performance and coordination metrics(including SEn). Results confirmed that meaningful temporal structure existed in the sequential type andtime of team motor responses. In addition, SEn was the only coordination metric to exhibit a significantrelationship with team performance outcomes. Together, these findings support the viability and salienceof nonlinear measures such as SEn in assessment of team coordination.
