人类和非人类灵长类动物行为和认知的神经行为学方法预测了社会生活的生物学特化。这里回顾的证据表明，祖先的机制经常被复制、改变用途，并受到不同的监管，以支持社会行为。聚焦于最近来自非人类灵长类动物的研究，我们描述了灵长类动物的大脑如何通过吸收和扩展先前支持非社会功能的先前存在的机制来实现社会功能。这种方法揭示了高度专门化的机制已经进化来破译直接的社会背景，而并行电路已经进化来将社会感知信号和非社会感知信号转化为部分整合的社会和非社会动机信号，这些信号共同形成了指挥行为的通用机制。物种之间以及物种内个体之间的社会行为差异，部分是由于这些神经回路的神经调节调节，而这些神经回路本身似乎受到部分基因控制。归根结底，社会行为的种内变异会产生不同的适合度结果，为自然选择提供基本的基石。我们的综述表明，对灵长类动物行为的神经行为学方法可能为人类精神病理学提供独特的见解。
A neuroethological approach to human and nonhuman primate behavior and cognition predicts biological specializations for social life. Evidence reviewed here indicates that ancestral mechanisms are often duplicated, repurposed, and differentially regulated to support social behavior. Focusing on recent research from nonhuman primates, we describe how the primate brain might implement social functions by coopting and extending preexisting mechanisms that previously supported nonsocial functions. This approach reveals that highly specialized mechanisms have evolved to decipher the immediate social context, and parallel circuits have evolved to translate social perceptual signals and nonsocial perceptual signals into partially integrated social and nonsocial motivational signals, which together inform general-purpose mechanisms that command behavior. Differences in social behavior between species, as well as between individuals within a species, result in part from neuro-modulatory regulation of these neural circuits, which itself appears to be under partial genetic control. Ultimately, intraspecific variation in social behavior has differential fitness consequences, providing fundamental building blocks of natural selection. Our review suggests that the neuroethological approach to primate behavior may provide unique insights into human psychopathology.
