Abstract

Mutual grooming, where both participants groom each other simultaneously, is a type of allogrooming and probably also plays an important role as a social and hygienic function; however, it has attracted little attention, probably due to its rarity compared to prevailing unidirectional grooming in many social animals, such as primate species. While previous studies have shown that mutual grooming has functional significance, such as promoting social bonds and maximizing short-term benefits, we do not know why mutual grooming is much rarer than unidirectional grooming, and its restrictive factors have been mostly uninvestigated. In this article, we propose a hypothesis of cognitive constraints in which cognitive complexity is assumed as an underpinning mechanism for mutual grooming, thereby restricting its prevalence across animal species. To achieve joint action and its symmetric nature, mutual grooming is considered to require behavioural coordination between participants, which could be facilitated by active communication and, furthermore, by joint commitment based on a mutual understanding of intention between the two. The fact that joint commitment has been proved only in a limited number of animals may support this cognitive demand hypothesis, although it definitely calls for further in-depth investigation and comparative studies across primate and non-primate species.

为什么尽管相互梳理有其作用,但却很少见?认知约束的假设。
相互梳理,即双方同时梳理对方,是一种异质梳理,可能在社交和卫生功能方面也起着重要作用;然而,它很少引起人们的注意,可能是因为与许多社会动物(如灵长类动物)普遍存在的单向梳理相比,它很罕见。虽然之前的研究表明,相互梳理具有重要的功能意义,例如促进社会联系和最大化短期利益,但我们不知道为什么相互梳理比单向梳理要少得多,其限制因素也大多未被调查。在本文中,我们提出了一种认知约束假说,其中认知复杂性被认为是相互梳理的基础机制,从而限制了其在动物物种中的流行。为了实现联合行动及其对称性质,相互梳理被认为需要参与者之间的行为协调,这可以通过积极的沟通来促进,此外,通过基于双方相互理解意图的联合承诺来促进。共同承诺只在有限数量的动物中得到证明,这一事实可能支持这一认知需求假说,尽管它肯定需要在灵长类动物和非灵长类动物之间进一步深入调查和比较研究。

期刊介绍: Previously a supplement to Proceedings B, and launched as an independent journal in 2005, Biology Letters is a primarily online, peer-reviewed journal that publishes short, high-quality articles, reviews and opinion pieces from across the biological sciences. The scope of Biology Letters is vast - publishing high-quality research in any area of the biological sciences. However, we have particular strengths in the biology, evolution and ecology of whole organisms. We also publish in other areas of biology, such as molecular ecology and evolution, environmental science, and phylogenetics.
