Bimanual Coordination and Right-Hand Bias in Extractive Foraging by Wild Sapajus libidinosus. [PDF]
Am J PrimatolWild Sapajus libidinosus exhibit a significant preference at the population level for using their right‐hand fingers to extract nut kernels when employing bimanual coordination. ABSTRACT Bimanual coordination is considered a crucial factor in the evolution of manual lateralization.

ON LOSS AVERSION IN CAPUCHIN MONKEYS [PDF]
Journal of the Experimental Analysis of Behavior, 2008 Chen, Lakshminarayanan, and Santos (2006) claim to show in three choice experiments that monkeys react rationally to price and wealth shocks, but, when faced with gambles, display hallmark, human‐like biases that include loss aversion. We present three experiments with monkeys and humans consistent with a reinterpretation of their data that attributes ...

Endowment effect in capuchin monkeys [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2008 In humans, the capacity for economically rational choice is constrained by a variety of preference biases: humans evaluate gambles relative to arbitrary reference points; weigh losses heavier than equally sized gains; and demand a higher price for owned goods than for equally preferred goods that are not yet owned.

Capuchin monkeys are sensitive to others' welfare [PDF]
Current Biology, 2008 SummaryHumans demonstrate altruistic behaviors in a variety of contexts [1,2], but there is growing experimental evidence that our closest living primate relative, the chimpanzee, does not always share our human prosocial tendencies [3,4]. Although chimpanzees behave cooperatively in some contexts, there is growing evidence that chimpanzees are ...
