Abstract
Recent research has shown that a collection of neurons in dorsal anterior cingulate cortex of rhesus monkeys may specifically encode the choice selection of an interaction partner. This raises interesting and important questions as to the nature of Theory of Mind processes in social interactive decision-making, with potential societal implications.
Highlights
In a recent compelling paper, Haroush & Williams [2] outline the case for a grouping of neurons in the primate brain that appear to encode the choice selection of an interaction partner
On the neural level: how do these “other”-encoding dACC neurons fit into a larger Theory of Mind (ToM) network that implements these computations
Given that the neural predictions were very accurate, and so presumably should not lead to different decisions than observation, what underlies this difference in cooperation rates? Does revealing one's intentions explicitly change how the ToM network of others is engaged, altering the tendency to cooperate by impacting the certainty of beliefs about the other’s behavior? It may require a revision of current models of strategic behavior to account for these different levels of cooperation
Summary
In a recent compelling paper, Haroush & Williams [2] outline the case for a grouping of neurons in the primate brain that appear to encode the choice selection of an interaction partner. Using the same signals they were able to predict the other, physically present, monkey's unobserved choices with even higher accuracy, namely 79%. Neurons encoded information enabling the monkey to, at least in principle, predict the other's future behavior with high accuracy.
