In- and Out-Groups01:31

In- and Out-Groups

39.9K
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.

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance01:14

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

150
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Frustration and Conflict: Approach-Approach, Approach-Avoidance

140
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Internal and External Forces01:12

Internal and External Forces

13.6K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

Robbers Cave

14.4K
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...

Levels of Communication I: Intrapersonal, Interpersonal, and Small Group

13.6K
Interpersonal communication focuses on the exchange of messages between two people.
We can participate in these relationships through verbal, nonverbal, and mediated communication. We engage in verbal communication when we use words during our interaction to convey specific meanings. On the other hand, nonverbal communication refers to various factors that can impact how we understand each other—for example, facial expressions.
We interact with others using mediated technologies like the...

Summary
This summary is machine-generated.

Intergroup conflict requires groups to solve collective action problems for defense. External conflict significantly impacts group organization, necessitating complex models beyond simple scaling of internal conflict dynamics.

Area of Science:

  • Social Psychology
  • Evolutionary Anthropology
  • Sociology

Background:

  • Intergroup conflict presents a collective action problem for group defense.
  • Existing models of intragroup conflict are insufficient for external conflict scenarios.
  • External conflict is known to influence group structure and dynamics.

Purpose of the Study:

  • To explore the complexities of collective action in intergroup conflict.
  • To investigate how external conflict shapes group organization.
  • To propose a framework that accounts for the unique challenges of intergroup conflict.

Main Methods:

  • Review of literature on cultural evolution and evolutionary psychology.
  • Theoretical modeling of group dynamics under external threat.
  • Comparative analysis of intragroup versus intergroup conflict resolution.

Main Results:

  • Overcoming collective action problems is crucial for group survival against external enemies.
  • External conflict introduces complexities that require more than scaled-up intragroup models.
  • Research indicates profound effects of external conflict on group organization.

Conclusions:

  • Group organization is significantly altered by external conflict.
  • New theoretical approaches are needed to understand group dynamics in intergroup conflict.
  • The study highlights the critical role of collective action in intergroup relations.
