On loss aversion in capuchin monkeys.
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 their results not to loss aversion, but to ...
متن کاملEffect of Deprivation on Delayed Response and Delayed Alternation Performance by Normal and Brain Operated Monkeys
3 monkeys impaired on delayed response and delayed alternation after midlateral frontal lesions, 3 monkeys unimpaired on these tasks after control lesions, and 3 unoperated monkeys were tested on spatial delayed response (with direct baiting) and spatial delayed alternation following 2, 26, and 50 hr. of food deprivation. Increased deprivation improved delayed response performance by all groups...
متن کاملEndowment effect in capuchin monkeys
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. To date, however, fewer studies have examined the origins of these biases. Here,...
متن کاملSelection of Effective Stone Tools by Wild Bearded Capuchin Monkeys
Appreciation of objects' affordances and planning is a hallmark of human technology. Archeological evidence suggests that Pliocene hominins selected raw material for tool making [1, 2]. Stone pounding has been considered a precursor to tool making [3, 4], and tool use by living primates provides insight into the origins of material selection by human ancestors. No study has experimentally inves...
متن کاملLocomotor delayed response in frontally ablated monkeys.
Monkeys which had been trained on a locomotor task, in which they were rewarded for (approaching a food cup located in a direction opposite to that of the stimulus, became severely impaired after bilateral 'ablations of dorsolateral prefrontal cortex, but not after damage t o other frontal lobe structures (Stepieli and Stamm 1969). The marked impairment, which was exhibited by responses indicat...
