As technological capabilities progress, there is a growing imperative to enhance collaborative dynamics within human-agent teams. Artificial agents and humans possess capabilities that compensate for each other’s limitations. This paper outlines the effect of communication using real-time textual explanations of the artificial agents’ mental model of its trust in the human teammate. An experiment (n = 40) was conducted by examining the impact of real-time textual explanations of the artificial agents’ trust beliefs. The participants collaborated with an artificial agent during a search and rescue mission in a 2D grid world, where they had to rescue six victims in a 10 minute time frame. The results show that real-time textual explanations did affect the natural trust and satisfaction positively compared to the baseline method.
