Much recent work has examined the evolutionary origins of human mental state representations. This work has yielded strikingly consistent results: primates show a sophisticated ability to track the current and past perceptions of others, but they fail to represent the beliefs of others. We offer a new account of the nuanced performance of primates in theory of mind (ToM) tasks. We argue that primates form awareness relations tracking the aspects of reality that other agents are aware of. We contend that these awareness relations allow primates to make accurate predictions in social situations, but that this capacity falls short of our human-like representational ToM. We end by explaining how this new account makes important new empirical predictions about primate ToM.
