This chapter examines the choice behaviours of rhesus monkeys during two different computerized competitive games in order to understand how decision-making strategies are adjusted during social interactions in nonhuman primates. The monkeys were trained to perform free-choice tasks modelled after matching pennies and rock–paper–scissors games. The findings reveal that the choice behaviour of the monkeys during both games is consistent with the predictions of reinforcement learning models and that the prefrontal cortex plays a key role in dynamically updating the animals' decision-making strategies.

Keywords:   choice behaviours, rhesus monkeys, competitive games, decision making, social interaction, nonhuman primates, leaning models, prefrontal cortex
