Deceptive behavior in primates has been the focus of a number of studies. Nevertheless, such abilities have never been demonstrated in prosimians. The authors' goal was to analyze possible deception in lemurs according to a paradigm used with simians. Three black lemurs were trained to communicate about the location of a hidden reward with a cooperative trainer. Afterward, when a 2nd trainer and lemurs competed to gain access to the reward, each subject differentially adapted its learned behavior to the context. Their performances with the cooperative trainer remained stable while they showed various behavioral adjustments when faced to the competitive trainer: 1 subject refused to participate, another preferentially withheld information, and the 3rd sometimes pointed deceptively to obtain the reward.
灵长类动物的欺骗行为一直是多项研究的焦点。然而，这种能力从未在原猴亚目动物中得到证实。作者的目标是根据用于猿猴亚目动物的范式来分析狐猴中可能存在的欺骗行为。三只黑狐猴接受训练，与一名合作的训练员交流隐藏奖励的位置。之后，当第二名训练员与狐猴竞争获取奖励时，每个受试对象会根据不同情况调整其所学行为。它们与合作训练员互动时的表现保持稳定，而面对竞争训练员时则表现出各种行为调整：一只受试对象拒绝参与，另一只优先隐瞒信息，第三只有时会通过欺骗性地指示来获取奖励。
