    This study investigated in 22 teams, individual and team trust measures reported by two human participants, recruited from a university populace, as they interacted with each other, robotic combat vehicles (RCVs), a human superior, and their team during a simulated Next Generation Combat Vehicle (NGCV) mission conducted within Minecraft. Trust was measured via survey questions based on established metrics and was found to be high toward the human peer, the human superior, and the overall team throughout the mission. In contrast, overall trust in the RCV was significantly lower in phases of the mission when breakdown in RCV functionality caused a hindrance in mission completion. Trust in the RCV was shown to recover as the mission progressed in phases without RCV maintenance issues. The findings reinforce that trust is distinguishable at the individual level and not necessarily perceived the same at the team level.

    Workplace research suggests that roughly equal communication between teammates is positively associated with team effectiveness. A distinction between teams in these studies and distributed action teams is the degree of role specialization and context-driven communication which may entail unequal degrees of communication. Yet, distributed action teams may have more equal footing to provide inputs in contexts such as mission planning or briefings. Twenty-two ad hoc teams participated in a simulated ground combat vehicle task in which teams conducted six-missions and briefed before each mission. We used team performance, team situation awareness, team workload, and team resilience as team effectiveness criteria. Balanced degrees of communication in mission briefs were correlated with performance and resilience measures, and largely uncorrelated with situation-awareness and workload measures. The overall amount of communication was also largely uncorrelated with all effectiveness measures. The results suggest that communication balance in mission briefs may help predict effectiveness in action teams.
