Robbers Cave04:49

Robbers Cave

14.6K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Impact of Groups on Groups

141
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

In- and Out-Groups

42.4K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Stereotypes, Prejudice, and Discrimination

94.2K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Surveys02:16

Surveys

16.4K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Sources of Self-Esteem III: Social Comparison

125
Social comparison plays a fundamental role in the evaluation of personal success and self-worth. Rather than assessing our achievements in isolation, we interpret their significance relative to personal goals and critically in comparison to the performance of others. A grade of B in a mathematics exam might elicit pride if one's expectation was a C, yet result in disappointment if an A was anticipated or if peers achieved superior results. These comparative evaluations illustrate how both...

Area of Science:

  • Behavioral Ecology
  • Evolutionary Game Theory
  • Social Evolution

Background:

  • Dyadic contest research extensively studies how individuals assess fighting ability and resources.
  • Intergroup contest research is growing, but assessment mechanisms remain poorly understood.
  • Assessment is key to contest outcomes, influencing strategy and resource allocation.

Purpose of the Study:

  • To adapt dyadic contest assessment principles to intergroup contests.
  • To identify traits assessed in intergroup contests (group, member, resource characteristics).
  • To elucidate how assessment influences intergroup contest behaviors and outcomes.

Main Methods:

  • Literature synthesis and theoretical adaptation.
  • Conceptual framework development for intergroup assessment.
  • Analysis of how assessment impacts contest dynamics.

Main Results:

  • Identified key assessed traits in intergroup contests.
  • Described manifestations of assessment in group behaviors and contest outcomes.
  • Highlighted the role of individual heterogeneity in group assessment.

Conclusions:

  • Assessment is a critical factor shaping intergroup contest dynamics.
  • Understanding intergroup assessment provides insights into group evolution and adaptation.
  • This framework advances the study of social conflict in group-living animals.
