In-group favoritismIn-group favoritism, sometimes known as in-group–out-group bias, in-group bias, intergroup bias, or in-group preference, is a pattern of favoring members of one's in-group over out-group members. This can be expressed in evaluation of others, in allocation of resources, and in many other ways. This effect has been researched by many psychologists and linked to many theories related to group conflict and prejudice. The phenomenon is primarily viewed from a social psychology standpoint.
Self-categorization theorySelf-categorization theory is a theory in social psychology that describes the circumstances under which a person will perceive collections of people (including themselves) as a group, as well as the consequences of perceiving people in group terms. Although the theory is often introduced as an explanation of psychological group formation (which was one of its early goals), it is more accurately thought of as general analysis of the functioning of categorization processes in social perception and interaction that speaks to issues of individual identity as much as group phenomena.
Social identity approach"Social identity approach" is an umbrella term designed to show that there are two methods used by academics to describe certain complex social phenomena- namely the dynamics between groups and individuals. Those two theoretical methods are called social identity theory and self-categorization theory. Experts describe them as two intertwined, but distinct, social psychological theories. The term "social identity approach" arose as an attempt to mitigate against the tendency to conflate the two theories, as well as the tendency to mistakenly believe one theory to be a component of the other.
Social organizationIn sociology, a social organization is a pattern of relationships between and among individuals and social groups. Characteristics of social organization can include qualities such as sexual composition, spatiotemporal cohesion, leadership, structure, division of labor, communication systems, and so on. And because of these characteristics of social organization, people can monitor their everyday work and involvement in other activities that are controlled forms of human interaction.
Social exchange theorySocial exchange theory is a sociological and psychological theory that studies the social behavior in the interaction of two parties that implement a cost-benefit analysis to determine risks and benefits. The theory also involves economic relationships—the cost-benefit analysis occurs when each party has goods that the other parties value. Social exchange theory suggests that these calculations occur in romantic relationships, friendships, professional relationships, and ephemeral relationships as simple as exchanging words with a customer at the cash register.
Social environmentThe social environment, social context, sociocultural context or milieu refers to the immediate physical and social setting in which people live or in which something happens or develops. It includes the culture that the individual was educated or lives in, and the people and institutions with whom they interact. The interaction may be in person or through communication media, even anonymous or one-way, and may not imply equality of social status. The social environment is a broader concept than that of social class or social circle.
Minimal group paradigmThe minimal group paradigm is a method employed in social psychology. Although it may be used for a variety of purposes, it is best known as a method for investigating the minimal conditions required for discrimination to occur between groups. Experiments using this approach have revealed that even arbitrary distinctions between groups, such as preferences for certain paintings, or the color of their shirts, can trigger a tendency to favor one's own group at the expense of others, even when it means sacrificing in-group gain.
Group conflictGroup conflict, or hostilities between different groups, is a feature common to all forms of human social organization (e.g., sports teams, ethnic groups, nations, religions, gangs), and also occurs in social animals. Although group conflict is one of the most complex phenomena studied by social scientists, the history of the human race evidences a series of group-level conflicts that have gained notoriety over the years. For example, from 1820 to 1945, it has been estimated that at least 59 million persons were killed during conflicts between groups of one type or another.
Peer groupIn sociology, a peer group is both a social group and a primary group of people who have similar interests (homophily), age, background, or social status. The members of this group are likely to influence the person's beliefs and behaviour. During adolescence, peer groups tend to face dramatic changes. Adolescents tend to spend more time with their peers and have less adult supervision. Adolescents' communication shifts during this time as well.
