为了更好地了解灵长类认知能力的进化,有关最基本的现存灵长类认知特征的信息可以提供重要的比较基线数据。与单目灵长类动物相比,狐猴的大脑相对较小,解决技术和社会领域问题的能力较弱。然而,最近的研究表明,狐猴的一些认知能力在性质上与单亲狐猴相当。在这里,我们回顾了研究环尾狐猴认知的技术和社会领域的认知能力的研究。在物理领域,环尾狐猴表现出与其他狐猴相似的定性认知技能,但也包括单目灵长类动物。在社会领域,环尾狐猴似乎比其他狐猴更善于从视觉角度进行选择。与其他狐猴相比,它们还拥有高度精细的交流技能。此外,雌性环尾狐猴在罕见的雌性驱逐事件中观察到了群体内联盟,但在其他狐猴物种中没有观察到。然而,在社会认知的其他几个方面,如和解和社会学习,环尾狐猴的认知能力与其他狐猴相同。因此,为了更全面地了解灵长类动物的认知进化过程,还需要对物理认知和社会认知进行更系统的比较研究。
In order to better understand the evolution of cognitive abilities in primates, information on cognitive traits of the most basal living primates can provide important comparative baseline data. Compared to haplorhine primates, lemurs have relatively smaller brains and reduced abilities to solve problems in the technical and social domain. However, recent studies have suggested that some cognitive abilities of lemurs are qualitatively equal to those of haplorhines. Here, we review studies investigating cognitive abilities in the technical and social domain of ring-tailed lemur cognition. In the physical domain, ring-tailed lemurs exhibit similar qualitative cognitive skills as other lemurs but also haplorhine primates. In the social domain, ring-tailed lemurs appear to be more skilled in visual perspective taking than other lemurs. Compared to other lemurs, they also have highly elaborated communicative skills. Moreover, within-group coalitions have been observed in female ring-tailed lemurs during rare events of female evictions but not in other lemur species. However, in several other aspects of social cognition, such as reconciliation and social learning, ring-tailed lemurs' cognitive abilities are equal to those of other lemurs. Thus, additional systematic comparative studies in physical and social cognition are required for a more comprehensive understanding of the processes of cognitive evolution among primates.
