In- and Out-Groups

42.9K
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.

Groupthink

48.9K
When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Robbers Cave

14.8K
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...

Group Polarization01:01

Group Polarization

38.4K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Impact of Groups on Individuals01:28

Impact of Groups on Individuals

285
Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...

Group Therapy01:26

Group Therapy

338
Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Summary

Group living presents cooperation challenges, potentially solved by evolved group-mindedness, not just larger brains. This suggests social cognition, not executive functions, drives group coordination in many species.

Area of Science:

  • Evolutionary biology
  • Primatology
  • Social cognition

Background:

  • Group living presents inherent challenges in cooperation and coordination.
  • These challenges are not limited to anthropoid primates.

Purpose of the Study:

  • To explore alternative mechanisms for managing group living challenges.
  • To investigate the role of group-mindedness versus executive functions in social coordination.

Main Methods:

  • Comparative analysis of social structures across species.
  • Theoretical modeling of cooperation and coordination dynamics.

Main Results:

  • Cooperation and coordination issues in group living are widespread.
  • Evolved group-mindedness may be a key factor in managing these challenges.
  • This contrasts with the hypothesis that expanded neocortical size and executive functions are the sole drivers.

Conclusions:

  • Group-mindedness offers a potential evolutionary solution to cooperation and coordination problems.
  • Social cognition may be more critical than enhanced executive functions for successful group living across diverse taxa.
