This study started with Ben Basile, who later acquired a PhD in primate cognition from Emory University. Ben’s senior thesis focused on whether tamarins who had emitted a behavior in synchrony with each other, in this case, sat together on a shelf to obtain a reward, would then be better able to share a common food source than monkeys who were primed with food but not required to perform a synchronous behavior with another tamarin. We found that in fact priming social awareness of others by requiring a synchronous move did increase the rate of food sharing in tamarins.
