DescriptionTrust is an important factor that impacts human-robot collaboration (HRC), where trust is dependent on several situational factors, such as operator fatigue and robot reliability. Current methods to assess trust predominantly include self-reports that cannot provide information about the subconscious cognitive or affective states, which may explain differences in trust experience under fatigued states. Given this knowledge gap, we conducted an HRC experiment on 16 sex-balanced participants in which trust was manipulated via robot reliability at two sessions (fatigue session, no fatigue session). Throughout, we monitored brain activity, performances, and subjective experiences to investigate the effect of fatigue and robot reliability on metrics of trust in HRC. A significant main effect of fatigue and reliability was observed on brain activations, effective
connectivity, subjective response, and performance. Insights from this investigation can advance objective trust measures under different states and help design better collaborations.
