Cultural Group Selection
Cultural group selection is an explanatory model within cultural evolution of how cultural traits evolve according to the competitive advantage they bestow upon a group. This multidisciplinary approach to the question of human culture engages research from the fields of anthropology, behavioural economics, evolutionary biology, evolutionary game theory, sociology, and psychology. While cultural norms are often beneficial to the individuals who hold them, they need not be. Norms can spread by cultural group selection when they are practiced within successful groups, and norms are more likely to spread from groups that are successful. But, for cultural group selection to occur, there must exist, between groups, cultural differences that when transmitted across time affect the persistence or proliferation of the groups.Campbell, D.T.

Cultural Evolution
Cultural evolution is an evolutionary theory of social change. It follows from the definition of culture as "information capable of affecting individuals' behavior that they acquire from other members of their species through teaching, imitation and other forms of social transmission". Cultural evolution is the change of this information over time. Cultural evolution, historically also known as sociocultural evolution, was originally developed in the 19th century by anthropologists stemming from Charles Darwin's research on evolution. Today, cultural evolution has become the basis for a growing field of scientific research in the social sciences, including anthropology, economics, psychology, and organizational studies. Previously, it was believed that social change resulted from biological adaptations; anthropologists now commonly accept that social changes arise in consequence of a combination of social, environmental, and biological influences (viewed from a nature vs nurture ...

Third-party Punishment
Third-party punishment is punishment of a transgressor (first party) which is administered, not by a victim of the transgression (second party), but rather by a third party not directly affected by the transgression. It has been argued that third-party punishments are the essence of social norms, as they are an evolutionarily stable strategy, unlike second-party punishments. It has also been shown that third-party punishments are exhibited in all examined populations, though the magnitude of the punishments varies greatly, and that costly punishment co-varies with altruistic behavior. Differences between within-group and inter-group altruistic punishments have also been observed. Experimental evidence Some of the common experiments in experimental economics concerning the study of second-party punishments with respect to distribution and cooperation norms have been dictator games and prisoner's dilemma games. These games can also be effectively used in the study of third-party puni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolutionary Game Theory
Evolutionary game theory (EGT) is the application of game theory to evolving populations in biology. It defines a framework of contests, strategies, and analytics into which Darwinism, Darwinian competition can be modelled. It originated in 1973 with John Maynard Smith and George R. Price's formalisation of contests, analysed as strategies, and the mathematical criteria that can be used to predict the results of competing strategies. Evolutionary game theory differs from classical game theory in focusing more on the dynamics of strategy change. This is influenced by the frequency of the competing strategies in the population. Evolutionary game theory has helped to explain the basis of altruism (biology), altruistic behaviours in Darwinian evolution. It has in turn become of interest to economists, sociologists, anthropologists, and philosophers. History Classical game theory Classical non-cooperative game theory was conceived by John von Neumann to determine optimal strategies i ...

Cultural Anthropology
Cultural anthropology is a branch of anthropology focused on the study of cultural variation among humans. It is in contrast to social anthropology, which perceives cultural variation as a subset of a posited anthropological constant. The term sociocultural anthropology includes both cultural and social anthropology traditions. Anthropologists have pointed out that through culture, people can adapt to their environment in non-genetic ways, so people living in different environments will often have different cultures. Much of anthropological theory has originated in an appreciation of and interest in the tension between the local (particular cultures) and the global (a universal human nature, or the web of connections between people in distinct places/circumstances). Cultural anthropology has a rich methodology, including participant observation (often called fieldwork because it requires the anthropologist spending an extended period of time at the research location), inter ...

Donald T
Donald is a Scottish masculine given name. It is derived from the Gaelic name ''Dòmhnall''.. This comes from the Proto-Celtic *''Dumno-ualos'' ("world-ruler" or "world-wielder"). The final -''d'' in ''Donald'' is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers. A short form of Donald is Don, and pet forms of Donald include Donnie and Donny. The feminine given name Donella is derived from Donald. ''Donald'' has cognates in other Celtic languages: Modern Irish ''Dónal'' (anglicised as ''Donal'' and ''Donall'');. Scottish Gaelic ''Dòmhnall'', ''Domhnull'' and ''Dòmhnull''; Welsh '' Dyfnwal'' and Cumbric ''Dumnagual''. Although the feminine given name '' Donna'' is sometimes used as a feminine form of ''Donald'', the names are not etymologically related. Variations Kings and noblemen Domnall or Domhnall is the name of many ancient and medieval Gaelic kings and noblemen: * Dyfnwal Moelmud (Dunvallo Molmutius), legendary ki ...

Asch Conformity Experiments
In psychology, the Asch conformity experiments were, or the Asch paradigm was, a series of studies directed by Solomon Asch studying if and how individuals yielded to or defied a majority (sociology), majority group and the effect of such influences on beliefs and opinions.Asch, S.E. (1952b). "Social psychology". Englewood Cliffs, NJ:Prentice Hall. Developed in the 1950s, the methodology remains in use by many researchers. Uses include the study of conformity effects of Conformity#Different stimuli, task importance, Conformity#Age, age, Conformity#Gender, sex, and Conformity#Culture, culture. Initial conformity experiment Rationale Many early studies in social psychology were adaptations of earlier work on "suggestibility" whereby researchers such as Edward Thorndike, Edward L. Thorndyke were able to shift the preferences of adult subjects towards majority or expert opinion. Still the question remained as to whether subject opinions were actually able to be changed, or if su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-similarity
In mathematics, a self-similar object is exactly or approximately similar to a part of itself (i.e., the whole has the same shape as one or more of the parts). Many objects in the real world, such as coastlines, are statistically self-similar: parts of them show the same statistical properties at many scales. Self-similarity is a typical property of fractals. Scale invariance is an exact form of self-similarity where at any magnification there is a smaller piece of the object that is similar to the whole. For instance, a side of the Koch snowflake is both symmetrical and scale-invariant; it can be continually magnified 3x without changing shape. The non-trivial similarity evident in fractals is distinguished by their fine structure, or detail on arbitrarily small scales. As a counterexample, whereas any portion of a straight line may resemble the whole, further detail is not revealed. Peitgen ''et al.'' explain the concept as such: Since mathematically, a fractal may sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Henrich
Joseph Henrich (born 1968) is an American anthropologist and professor of human evolutionary biology at Harvard University. Before arriving at Harvard, Henrich was a professor of psychology and economics at the University of British Columbia. He is interested in the question of how humans evolved from "being a relatively unremarkable primate a few million years ago to the most successful species on the globe", and how culture shaped our species' genetic evolution. Biography Henrich holds bachelor's degrees in anthropology and aerospace engineering from the University of Notre Dame, earned in 1991. From 1991 to 1993, he worked as a Test and Evaluation Systems Engineer for General Electric Aerospace (sold to Martin Marietta in 1993) in Springfield, Virginia. In 1995, he earned a master's degree and, four years later, a doctorate in anthropology from the University of California at Los Angeles. From 2002 to 2007, Henrich was on the faculty of Emory University in the Department of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intersubjectivity
Intersubjectivity describes the shared understanding that emerges from interpersonal interactions. The term first appeared in social science in the 1970s and later incorporated into psychoanalytic theory by George E. Atwood and Robert Stolorow, the term has since been adopted across various fields. In phenomenology, philosophers such as Edmund Husserl and Edith Stein examined intersubjectivity in relation to empathy and experience, while in psychology it is used to analyze how individuals attribute mental states to others and coordinate behavior. Definition is a term coined by social scientists beginning around 1970 to refer to a variety of types of human interaction. The term was introduced to psychoanalysis by George E. Atwood and Robert Stolorow, who consider it a "meta-theory" of psychoanalysis. For example, social psychologists Alex Gillespie and Flora Cornish listed at least seven definitions of intersubjectivity (and other disciplines have additional definitions): * ...

Imitative Learning
Imitative learning is a type of social learning whereby new behaviors are acquired via imitation. Imitation aids in communication, social interaction, and the ability to modulate one's emotions to account for the emotions of others, and is "essential for healthy sensorimotor development and social functioning". The ability to match one's actions to those observed in others occurs in humans and animals; imitative learning plays an important role in humans in cultural development. Imitative learning is different from observational learning in that it requires a duplication of the behaviour exhibited by the model, whereas observational learning can occur when the learner observes an unwanted behaviour and its subsequent consequences and as a result learns to avoid that behaviour. Imitative learning in animals On the most basic level, research performed by A.L. Saggerson, David N. George, and R.C. Honey showed that pigeons were able to learn a basic process that would lead to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
