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 differences between choice alternatives in delay of reinforcement.
陈、拉克什米纳拉亚南和桑托斯(2006年)声称,在三项选择实验中表明,猴子对价格和财富冲击做出了理性反应,但在面对赌博时,却表现出包括损失厌恶在内的典型的、类似人类的偏差。我们用猴子和人类进行了三项实验,这些实验与对他们数据的重新解释一致,该解释将他们的结果归因于强化延迟中选择选项之间的差异,而非损失厌恶。
