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.

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.

Social Loafing01:37

Social Loafing

38.9K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Deindividuation00:57

Deindividuation

30.2K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Groupthink01:34

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...

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...

Summary
This summary is machine-generated.

Humans maintain larger social networks than primates using mental abstraction. This cognitive ability allows for fuzzy network representations, aiding information flow and conflict resolution in complex social structures.

Area of Science:

  • Cognitive Science
  • Social Neuroscience
  • Anthropology

Background:

  • Human social networks are significantly larger than those observed in nonhuman primates.
  • Maintaining social cohesion within these extensive networks presents a significant evolutionary challenge.
  • Existing explanations for large-scale social cohesion often lack parsimony.

Purpose of the Study:

  • To propose mental abstraction as a parsimonious mechanism for maintaining human social cohesion.
  • To explore how mental abstraction facilitates the management of large and complex social networks.
  • To investigate the role of cognitive processes in large-scale social organization.

Main Methods:

  • Theoretical modeling of social network dynamics.
  • Comparative analysis of human and nonhuman primate social structures.
  • Cognitive psychology principles applied to social network maintenance.

Main Results:

  • Mental abstraction enables the creation of simplified, 'fuzzy' representations of social networks.
  • These representations effectively track information flow within dense community structures.
  • Fuzzy network representations help mitigate interpersonal conflict by abstracting away fine-grained social details.

Conclusions:

  • Mental abstraction offers a parsimonious explanation for the evolution and maintenance of large human social networks.
  • Cognitive tools like mental abstraction are crucial for navigating complex social environments.
  • Understanding mental abstraction sheds light on human uniqueness in sociality.
