Knowing which of correlated traits are more strongly targeted by selection is crucial to understand the evolutionary process. For example, it could help in understanding how behavioural and cognitive adaptations to social living have evolved. Social competence is the ability of animals to optimize their social behaviours according to the demands of their social environment. It is a behavioural performance trait that expresses how well a whole organism performs complex social tasks, such as choosing mates, raising offspring, participating in dominance hierarchies, solving conflicts or forming social bonds. Non‐social competence, on the other hand, is the ability of animals to optimize their non‐social behaviours according to the demands of their non‐social environment, such as finding food or avoiding predators. Social and non‐social cognition are correlated lower‐level traits of social and non‐social competence, respectively, encompassing the underlying psychological and neural mechanisms of behaviour that allow animals to acquire, encode, store and recall information about their social and non‐social environments. Here, we employ the theoretical framework that selection acts on performance traits first and on lower‐level traits only secondarily, to propose a new approach to the study of the evolution of social cognition. We hypothesize that when selection favours social competence, the cognitive system becomes more adapted to the social domain, making species biased for social information, and increasing their degree of sociality. The opposite can happen when selection favours non‐social competence. The level of specialization that the cognitive system can attain depends on whether social and non‐social competence are correlated with the same cognitive lower‐level traits. This in turn will determine whether species will evolve a type of social cognition that is general—that contributes with cognitive abilities that can be used in both social and non‐social environments—or modular—that contributes with cognitive abilities that are specific to the social environment.

社会能力与社会认知的相关演化

了解哪些相关性状更受选择的影响对于理解进化过程至关重要。例如,它可以帮助理解对社会生活的行为和认知适应是如何演变的。社会能力是动物根据社会环境的需要优化其社会行为的能力。它是一种行为表现特征,表示整个生物体执行复杂社会任务的能力,例如选择配偶、抚养后代、参与支配等级、解决冲突或形成社会纽带。另一方面,非社会能力是动物根据其非社会环境的需求优化其非社会行为的能力,例如寻找食物或避免捕食者。社会和非社会认知分别是社会和非社会能力的相关低级特征,包括行为的潜在心理和神经机制,这些机制允许动物获取、编码、存储和回忆有关其社会和非社会信息环境。在这里,我们采用选择首先作用于绩效特征,其次作用于低级特征的理论框架,提出了一种研究社会认知演化的新方法。我们假设选择有利于社会能力时,认知系统变得更加适应社会领域,使物种偏向社会信息,增加社会性程度。选择有利于非社会能力时,相反会发生。认知系统能够达到的专业化水平取决于社会和非社会能力是否与相同的低层次认知特征相关。这反过来将决定物种是否会进化出一种普遍的社会认知——它有助于在社会和非社会环境中使用的认知能力——或模块化——有助于特定于社会的认知能力。环境。可以在本文的支持信息中找到免费的普通语言摘要。这反过来将决定物种是否会进化出一种普遍的社会认知——它有助于在社会和非社会环境中使用的认知能力——或模块化——有助于特定于社会的认知能力。环境。可以在本文的支持信息中找到免费的普通语言摘要。这反过来将决定物种是否会进化出一种普遍的社会认知——它有助于在社会和非社会环境中使用的认知能力——或模块化——有助于特定于社会的认知能力。环境。可以在本文的支持信息中找到免费的普通语言摘要。
