Dependence of collective performance on inter-agent neural synchrony

Ascertain whether, and under what conditions, the performance of collective decision making by embodied agents controlled with Haken–Kelso–Bunz (HKB) neural dynamics depends on inter-agent neural synchrony (inter-brain synchrony).

Background

The paper measures coordination within and between agents using phase-based metrics (e.g., wPLI) and reports regimes where movement alignment and neural covariance vary with internal, social, and environmental coupling. However, the results do not establish a causal or necessary link between inter-agent neural synchrony and decision performance, leaving open whether performance depends on such synchrony.
