Experimental Findings

There are many theories of the function of dreams, such as memory consolidation, emotion processing, threat simulation and social simulation. In general, such theories hold that the function of dreams occurs within sleep; occurs for unrecalled dreams as well as for dream that are recalled on awakening; and that conscious recall of dreams is not necessary for their function to occur. In contrast, we propose that dreams have an effect of enhancing empathy and group bonding when dreams are shared and discussed with others. We propose also that this effect would have occurred in history and pre-history and, as it would have enhanced the cohesiveness and mutual understanding of group members, the fictional and engaging characteristics of dream content would have been selected for during human social evolution, interacting with cultural practices of dream-sharing. Such dream-sharing may have taken advantage of the long REM periods that occur for biological reasons near the end of the night. Dream-production and dream-sharing may have developed alongside story-telling, utilising common neural mechanisms. Dream-sharing hence would have contributed to Human Self-Domestication, held by many researchers to be the primary driver of the evolution of human prosociality, tolerance and reduced intragroup emotional reactivity. We note that within-sleep theories of dream function rely on correlational rather than experimental findings, and have as yet untested and speculative mechanisms, whereas post-sleep effects of dream-sharing are easily testable and have mechanisms congruent with the social processes proposed by the theory of Human Self-Domestication.

Group size in primates is strongly correlated with brain size, but exactly what makes larger groups more ‘socially complex’ than smaller groups is still poorly understood. Chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla) are among our closest living relatives and are excellent model species to investigate patterns of sociality and social complexity in primates, and to inform models of human social evolution. The aim of this paper is to propose new research frameworks, particularly the use of social network analysis, to examine how social structure differs in small, medium and large groups of chimpanzees and gorillas, to explore what makes larger groups more socially complex than smaller groups. Given a fission-fusion system is likely to have characterised hominins, a comparison of the social complexity involved in fission-fusion and more stable social systems is likely to provide important new insights into human social evolution

The chapter on culture and identity defines the current use of these terms and discusses how culture influences identity formation from a developmental perspective, starting in early childhood and throughout the life span. It also introduces new neurobiological findings related to theory of mind, neural mapping, object representation, and emotional reactivity and how these exert an influence on culture and identity formation. It covers a historical perspective that includes the contributions of pioneers such as Freud, Vigotsky, Montessori, Bandura, Mead, and Erikson. It also discusses ethnicity and race and the social and biological origins of prejudice and explains the meaning of ethnic-racial socialization messages, the dynamics of biracial identities, the importance of language in the development of the American identity and the role of culture and identity in psycho-social functioning and resiliency, including such variables as religion and spirituality. It also describes the influences of globalization and the diminishing importance of national boundaries on cultural identity for both minority and majority group members. Some of the concepts are illustrated and explained with clinical cases.

Insight Into

A small number of primate species including snub-nosed monkeys (colobines), geladas (papionins) and humans live in multilevel societies (MLSs), in which multiple one-male polygamous units (OMUs) coexist to form a band, and non-breeding males associate in bachelor groups. Phylogenetic reconstructions indicate that the papionin MLS appears to have evolved through internal fissioning of large mixed-sex groups, whereas the colobine MLS evolved through the aggregation of small, isolated OMUs. However, how agonistic males maintain tolerance under intensive competition over limited breeding opportunities remains unclear. Using a combination of behavioural analysis, satellite telemetry and genetic data, we quantified the social network of males in a bachelor group of golden snub-nosed monkeys. The results show a strong effect of kinship on social bonds among bachelors. Their interactions ranged from cooperation to agonism, and were regulated by access to mating partners. We suggest that an ‘arms race’ between breeding males' collective defence against usurpation attempts by bachelor males and bachelor males' aggregative offence to obtain reproductive opportunities has selected for larger group size on both sides. The results provide insight into the role that kin selection plays in shaping inter-male cohesion which facilities the evolution of multilevel societies. These findings have implications for understanding human social evolution, as male–male bonds are a hallmark of small- and large-scale human societies.

Self Consistency

The importance of culture for human social evolution hinges largely on the extent to which culture supports outcomes that would not otherwise occur. An especially controversial claim is that social learning leads groups to coalesce around group-typical behaviours and associated social norms that spill over to shape choices in asocial settings. To test this, we conducted an experiment with 878 groups of participants in 116 communities in Sudan. Participants watched a short film and evaluated the appropriate way to behave in the situation dramatized in the film. Each session consisted of an asocial condition in which participants provided private evaluations and a social condition in which they provided public evaluations. Public evaluations allowed for social learning. Across sessions, we randomized the order of the two conditions. Public choices dramatically increased the homogeneity of normative evaluations. When the social condition was first, this homogenizing effect spilled over to subsequent asocial conditions. The asocial condition when first was thus alone in producing distinctly heterogeneous groups. Altogether, information about the choices of others led participants to converge rapidly on similar normative evaluations that continued to hold sway in subsequent asocial settings. These spillovers were at least partly owing to the combined effects of conformity and self-consistency. Conformity dominated self-consistency when the two mechanisms were in conflict, but self-consistency otherwise produced choices that persisted through time. Additionally, the tendency to conform was heterogeneous. Females conformed more than males, and conformity increased with the number of other people a decision-maker observed before making her own choice.

This chapter compares the social behaviour of human hunter-gatherers with that of the better-studied chimpanzee species, Pan troglodytes, in an attempt to pinpoint the unique features of human social evolution. Although hunter-gatherers and chimpanzees living in central Africa have similar body weights, humans live at much lower population densities due to their greater dependence on predation. Human foraging parties have longer duration than those of chimpanzees, lasting hours rather than minutes, and a higher level of mutual dependence, through the division of labour between men (hunting) and women (gathering); which is in turn related to pair-bonding, and meat sharing to reduce the risk of individual hunters' failure on any particular day. The band appears to be a uniquely human social unit that resolves the tension between greater dispersion and greater interdependence.

Social Coercion

All prior attempts to understand human origins, behavior, and history have led to paradoxes and dilemmas, highly resistant to resolution. This chapter reviews specific cases of failures to resolve these apparent paradoxes and dilemmas in human evolution and the social sciences. The authors argue that these failures are rooted in confusing proximate with ultimate causation. They further argue that a sound theory of human origins, behavior, and history (social coercion theory) can help to understand the human condition scientifically; specifically, this theory argues that all the unique properties of humans emerge from the unprecedented human social evolution, driven, in turn by the evolution of cost-effective coercive management of conflicts of interest. Finally, the authors argue that social coercion theory yields the first general theory of history, economics, and politics, which provides an approach to problems within the social sciences while armed with a grasp of ultimate causation. Consequently, formerly intractable scientific questions and social concerns become manageable and solvable.

Artificial life is concerned with understanding the dynamics of human societies. A defining feature of any society is its institutions. However, defining exactly what an institution is has proven difficult, with authors often talking past each other. This article presents a dynamic model of institutions, which views them as political game forms that generate the rules of a group's economic interactions. Unlike most prior work, the framework presented here allows for the construction of explicit models of the evolution of institutional rules. It takes account of the fact that group members are likely to try to create rules that benefit themselves. Following from this, it allows us to determine the conditions under which self-interested individuals will create institutional rules that support cooperation—for example, that prevent a tragedy of the commons. The article finishes with an example of how a model of the evolution of institutional rewards and punishments for promoting cooperation can be created. It is intended that this framework will allow artificial life researchers to examine how human groups can themselves create conditions for cooperation. This will help provide a better understanding of historical human social evolution, and facilitate the resolution of pressing societal social dilemmas.

This paper examines Charlotte Perkins Gilman's connection with the evolutionist ideas of late nineteenth century Reform Darwinism. It focuses on the assumptions that her language and use of metaphor reveal, and upon her vision of human social evolution as a meUoristic process through which the equality of the sexes must finally emerge.

Yzerbyt, Rogier and Fiske (1998) argued that perceivers confronted with a group high in entitativity (i.e., a group perceived as an entity, a tight-knit group) more readily call upon an underlying essence to explain people's behavior than perceivers confronted with an aggregate. Their study showed that group entitativity promoted dispositional attributions for the behavior of group members. Moreover, stereotypes emerged when people faced entitative groups. In this study, we replicate and extend these results by providing further evidence that the process of social attribution is responsible for the emergence of stereotypes. We use the attitude attribution paradigm ( Jones & Harris, 1967 ) and show that the correspondence bias is stronger for an entitative group target than for an aggregate. Besides, several dependent measures indicate that the target's group membership stands as a plausible causal factor to account for members' behavior, a process we call Social Attribution. Implications for current theories of stereotyping are discussed.

Conceptual Foundations

The article discusses the conceptual foundations of the development of the general sociological theory of J.G.Turner. These foundations are metatheoretical ideas, basic concepts and an analytical scheme. Turner began to develop a general sociological theory with a synthesis of metatheoretical ideas of social forces and social selection. He formulated a synthetic metatheoretical statement: social forces cause selection pressures on individuals and force them to change the patterns of their social organization and create new types of sociocultural formations to survive under these pressures. Turner systematized the basic concepts of his theorizing with the allocation of micro-, meso- and macro-levels of social reality. On this basis, he substantiated a simple conceptual scheme of social dynamics. According to this scheme, the forces of macrosocial dynamics of the population, production, distribution, regulation and reproduction cause social evolution. These forces force individual and corporate actors to structurally adapt their communities in altered circumstances. Such adaptation helps to overcome or avoid the disintegration consequences of these forces. The initial stage of Turner's general theorizing is a kind of audit, modification, modernization and systematization of the conceptual apparatus of sociology. The initial results obtained became the basis for the development of his conception of the dynamics of functional selection in the social world.
