Evolutionary psychology is a theoretical approach in the social and natural sciences that examines psychological structure from a modern evolutionary perspective. It seeks to identify which human psychological traits are evolved adaptations – that is, the functional products of natural selection or sexual selection in human evolution. Adaptationist thinking about physiological mechanisms, such as the heart, lungs, and immune system, is common in evolutionary biology. Some evolutionary psychologists apply the same thinking to psychology, arguing that the modularity of mind is similar to that of the body and with different modular adaptations serving different functions. These evolutionary psychologists argue that much of human behavior is the output of psychological adaptations that evolved to solve recurrent problems in human ancestral environments.
Leadership is both a research area and a practical skill encompassing the ability of an individual, group or organization to "lead", influence or guide other individuals, teams, or entire organizations. Often viewed as a contested term, specialist literature debates various viewpoints, contrasting Eastern and Western approaches to leadership, and also North American versus European approaches.
The concept of interpersonal relationship involves social associations, connections, or affiliations between two or more people. Interpersonal relationships vary in their degree of intimacy or self-disclosure, but also in their duration, in their reciprocity and in their power distribution, to name only a few dimensions. The context can vary from family or kinship relations, friendship, marriage, relations with associates, work, clubs, neighborhoods, and places of worship. Relationships may be regulated by law, custom, or mutual agreement, and form the basis of social groups and of society as a whole.
Social status is a measurement of social value. More specifically, it refers to the relative level of respect, honor, assumed competence, and deference accorded to people, groups, and organizations in a society. Some writers have also referred to a socially valued role or category a person occupies as a "status". Status is based in beliefs about who members of a society believe holds comparatively more or less social value. By definition, these beliefs are broadly shared among members of a society. As such, people use status hierarchies to allocate resources, leadership positions, and other forms of power. In doing so, these shared cultural beliefs make unequal distributions of resources and power appear natural and fair, supporting systems of social stratification. Status hierarchies appear to be universal across human societies, affording valued benefits to those who occupy the higher rungs, such as better health, social approval, resources, influence, and freedom.
Instinct or innate behavior is the inherent inclination of a living organism towards a particular complex behavior. The simplest example of an instinctive behavior is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding clearly defined stimulus.
Modularity of mind is the notion that a mind may, at least in part, be composed of innate neural structures or mental modules which have distinct, established, and evolutionarily developed functions. However, different definitions of "module" have been proposed by different authors. According to Jerry Fodor, the author of Modularity of Mind, a system can be considered 'modular' if its functions are made of multiple dimensions or units to some degree. One example of modularity in the mind is binding. When one perceives an object, they take in not only the features of an object, but the integrated features that create a whole. Instead of just seeing red, round, plastic, and moving, the subject may experience a rolling red ball. Binding may suggest that the mind is modular because it takes multiple cognitive processes to perceive one thing.
The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language. The timeline of human evolution spans approximately 9 million years, from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago. The first 3 million years of this timeline concern Sahelanthropus, the following 2 million concern Australopithecus and the final 2 million span the history of the genus Homo in the Paleolithic era.
Evolutionary ethics is a field of inquiry that explores how evolutionary theory might bear on our understanding of ethics or morality. The range of issues investigated by evolutionary ethics is quite broad. Supporters of evolutionary ethics have claimed that it has important implications in the fields of descriptive ethics, normative ethics, and metaethics.
Deference is the condition of submitting to the espoused, legitimate influence of one's superior or superiors. Deference implies a yielding or submitting to the judgment of a recognized superior, out of respect or reverence. Deference has been studied extensively by political scientists, sociologists, and psychologists.
Social dominance theory (SDT) is a social psychological theory of intergroup relations that examines the caste-like features of group-based social hierarchies, seeking to explain how they remain stable and perpetuate themselves. According to the theory, group-based inequalities are maintained through three primary mechanisms: institutional discrimination, aggregated individual discrimination, and behavioral asymmetry. The theory proposes that widely shared cultural ideologies provide the moral and intellectual justification for these intergroup behaviors, serving to disguise privilege as “normal”. For data collection and validation of predictions, the social dominance orientation (SDO) scale was composed to measure acceptance of and desire for group-based social hierarchy using two factors: 1) support for group-based dominance and 2) generalized opposition to equality, regardless of the in-group’s position in the power structure. Though the scale is used in other social and political psychology studies with disparate goals including those exploring the causes of the orientation, social dominance theory’s perspective is that explaining the orientation cannot explain group based dominance due to its role as just one of many factors that act as both partial effect as well as partial cause of group based dominance.
Evolutionary psychology has generated significant controversy and criticism. The criticism includes: disputes about the testability of evolutionary hypotheses, alternatives to some of the cognitive assumptions frequently employed in evolutionary psychology, alleged vagueness stemming from evolutionary assumptions, differing stress on the importance of non-genetic and non-adaptive explanations, and political and ethical issues.
Evolutionary approaches to depression are attempts by evolutionary psychologists to use the theory of evolution to shed light on the problem of mood disorders. Depression is generally thought of as dysfunction or a mental disorder, but its prevalence does not increase with age the way dementia and other organic dysfunction commonly does. Some researchers have surmised that the disorder may have evolutionary roots, in the same way that others suggest evolutionary contributions to schizophrenia, sickle cell anemia, psychopathy and other disorders. Psychology and psychiatry have not generally embraced evolutionary explanations for behaviors, and the proposed explanations for the evolution of depression remain controversial.
The evolution of morality refers to the emergence of human moral behavior over the course of human evolution. Morality can be defined as a system of ideas about right and wrong conduct. In everyday life, morality is typically associated with human behavior, and not much thought is given to the social conducts of other creatures. The emerging fields of evolutionary biology and in particular evolutionary psychology have argued that, though human social behaviors are complex, the precursors of human morality can be traced to the behaviors of many other social animals. Sociobiological explanations of human behavior are still controversial. The traditional view of social scientists has been that morality is a construct, and is thus culturally relative, although others argue that there is a science of morality.
The evolutionary psychology of religion is the study of religious belief using evolutionary psychology principles. It is one approach to the psychology of religion. As with all other organs and organ functions, the brain's functional structure is argued to have a genetic basis, and is therefore subject to the effects of natural selection and evolution. Evolutionary psychologists seek to understand cognitive processes, religion in this case, by understanding the survival and reproductive functions they might serve.
Human ethology is the study of human behavior. Ethology as a discipline is generally thought of as a sub-category of biology, though psychological theories have been developed based on ethological ideas. The bridging between biological sciences and social sciences creates an understanding of human ethology. The International Society for Human Ethology is dedicated to advancing the study and understanding of human ethology.
Mark van Vugt is a Dutch evolutionary psychologist who holds a professorship in evolutionary psychology and work and organizational psychology at the VU University Amsterdam, the Netherlands. Van Vugt has affiliate positions at the University of Oxford, Institute for Cognitive and Evolutionary Anthropology (ICEA).
The history of evolutionary psychology began with Charles Darwin, who said that humans have social instincts that evolved by natural selection. Darwin's work inspired later psychologists such as William James and Sigmund Freud but for most of the 20th century psychologists focused more on behaviorism and proximate explanations for human behavior. E. O. Wilson's landmark 1975 book, Sociobiology, synthesized recent theoretical advances in evolutionary theory to explain social behavior in animals, including humans. Jerome Barkow, Leda Cosmides and John Tooby popularized the term "evolutionary psychology" in their 1992 book The Adapted Mind: Evolutionary Psychology and The Generation of Culture. Like sociobiology before it, evolutionary psychology has been embroiled in controversy, but evolutionary psychologists see their field as gaining increased acceptance overall.
Followership is the actions of someone in a subordinate role. It can also be considered as a specific set of skills that complement leadership, a role within a hierarchical organization, a social construct that is integral to the leadership process, or the behaviors engaged in while interacting with leaders in an effort to meet organizational objectives. As such, followership is best defined as an intentional practice on the part of the subordinate to enhance the synergetic interchange between the follower and the leader.
The following outline is provided as an overview of and topical guide to evolution:
The theory of regal and kungic societal structures, or regality theory, is a theory that seeks to explain certain cultural differences based on perceived collective danger and fear.
