Social Brain Hypothesis and Human Evolution
The social brain hypothesis argues that primates have large brains because they need to manage complex social relationships. This article reviews the evidence for this hypothesis and its implications for human cognition and sociality.
The social brain hypothesis and its implications for social evolution
The social brain hypothesis was proposed as an explanation for the fact that primates have unusually large brains for body size compared to all other vertebrates: Primates evolved large brains to manage their unusually complex social systems. Although this proposal has been generalized to all vertebrate taxa as an explanation for brain ...
The Social Brain: Neural Basis of Social Knowledge
The Social Brain. The social brain hypothesis attempts to explain the extraordinary size and complexity of the human brain by appeal to particular pressures that a species adapted to social interaction would have had to face, ranging from deception to cooperation to ways of obtaining food and ensuring offspring (Allman 1999; Barrett & Henzi ...
Social Brain Hypothesis
Learn how the social brain hypothesis explains the evolution and function of the primate brain in relation to social complexity and group size. Explore how the social environment, maternal care, and speech influence brain development and stress regulation across the life course.
The social brain hypothesis: An evolutionary perspective on the
This chapter reviews the evidence for the social brain hypothesis, which proposes that the human brain has evolved to support complex social cognition and communication. It focuses on the cognitive powers of Theory of Mind, which enable us to attribute mental states to others, and the brain regions involved in this process.
Social Brain Hypothesis
The social brain hypothesis argues the computational demands of living in highly complex social groups selected for overall increases in primate brain volume—including humans—explaining in large part the unusually large brains of many primate species. In particular, among both corvids and anthropoid primates, unusually high encephalization ...

The social brain hypothesis argues that primates' large neocortices are adaptations for living in complex social groups. This article reviews the evidence for and against this hypothesis, and its implications for social cognition, language, and culture in hominids.

The Social Brain: Mind, Language, and Society in Evolutionary
Abstract The social brain (or Machiavellian Intelligence) hypothesis was proposed to explain primates' unusually large brains: It argues that the cognitive demands of living in complexly bonded social groups selected for increases in executive brain (principally neocortex). The evidence for this and alternative hypotheses is reviewed. Although there remain difficulties of interpretation ...
Dunbar's Number: Why the Theory That Humans Can Only Maintain 150
The community level of organisation turned out to be almost exactly 150. Thus was born the "social brain hypothesis" and "Dunbar's number", the former referring to the relationship between group size and brain size in primates and the latter referring to the natural group size of about 150 for humans.
Social brains, simple minds: does social complexity really require
The social brain hypothesis is a well-accepted and well-supported evolutionary theory of enlarged brain size in the non-human primates. Nevertheless, it tends to emphasize an anthropocentric view of social life and cognition. This often leads to confusion between ultimate and proximate mechanisms, and an over-reliance on a Cartesian ...
Explaining brain size variation: from social to cultural brain
Abstract. Although the social brain hypothesis has found near-universal acceptance as the best explanation for the evolution of extensive variation in brain size among mammals, it faces two problems. First, it cannot account for grade shifts, where species or complete lineages have a very different brain size than expected based on their social ...

(13, 21), and these have largely supported the social hypothesis, there has been little effort to develop an explanatory framework that integrates the many social, ecological, and life-history correlates of brain size that have been identified. As a ...

Social brain hypothesis 567 attentive are klipspringer to each other's whereabouts and behaviour that they are rarely found more than a couple of metres apart. Similarly, among the small monogamous New World cebids, mates maintain close spatial proximity both when resting and when foraging. When resting, they are often to be found sitting ...
Experts in action: why we need an embodied social brain hypothesis
A tale of two brains. Today, the social brain hypothesis (SBH) is well established as an explanation for the link between large brains and intense sociality among the anthropoid primates [ 1 - 5 ]. The SBH argues that the need to live in large groups selected for increased brain size and, by extension, the cognitive capacities needed to ...

What is the social brain?
The social brain is a network of brain regions that support social interaction, such as understanding and telling jokes. Learn how the social brain develops, how it is influenced by environment and genetics, and how it differs in autism.

[2302.00075] Cooperation and the social brain hypothesis in primate
The social brain hypothesis states that the relative size of the neocortex is larger for species with higher social complexity as a result of evolution. Various lines of empirical evidence have supported the social brain hypothesis, including evidence from the structure of social networks. Social complexity may itself positively impact cooperation among individuals, which occurs across ...
The Social Brain Hypothesis: An Evolutionary Perspective on the
The third, and most recent, version of the Social Brain Hypothesis, proposed by Reader and Laland (2002, Reader et al. 2011), has focused on the role of social learning, with a particular emphasis on the benefits to be derived from the social transmission of ecological knowledge and foraging skills. Social learning in this context is the ...
