Introduction to Groups

  • Definition of groups: Collections of individuals sharing common characteristics.
  • Examples of groups:
    • Gender, ethnicity, social class, occupation, hobbies.
  • Group membership can evolve over time (e.g., life stages, experiences).

Need to Belong Theory

  • Baumeister & Leary (1995): Proposed that the need to belong is fundamental, comparable to basic needs like hunger.
    • Social isolation impacts: Elicits brain responses akin to hunger (Tomova et al., 2020).
  • Distinction from attachment theory:
    • Focus on various significant relationships, not just caregivers.
Key Components of Need to Belong
  • Fulfillment of need: Requires:
    • Positive interactions in stable relationships.
  • Concepts:
    • Satiation: Seeking new relationships when there are enough existing ones.
    • Substitution: Replacing lost relationships.
  • Individual differences in the need for belonging:
    • High Need to Belong: Strong desire for acceptance, heightened reactions to exclusion.
    • Low Need to Belong: Preference for fewer close relationships.

Social Identity Theory

  • Tajfel & Turner (1979): Importance of group memberships on self-perception.
  • Social vs. personal identities:
    • Social identities: Traits derived from group memberships.
    • Personal identities: Individual characteristics.
Components of Social Identity Theory
  1. Categorisation: Grouping people based on observable traits.
  2. Identification: Groups we see ourselves as members of.
  3. Comparison: Comparing our in-group with out-groups.
In-groups and Out-groups
  • In-group: Identifiable group that one supports and feels loyalty toward.
  • Out-group: Groups with which one does not identify.
  • Social Identity Theory suggests in-group discrimination to enhance self-image.
Group Prototypes
  • Defined attributes for members of a group:
    • Influence conformity to in-group behaviors.
    • Guide treatment of out-group members based on perceived prototypes.

Group Identification

  • Benefits of group identification:
    • Provides belonging, self-esteem, identity, and purpose.
  • Risks:
    • Potential for bias favoring in-group members over others.

Bias in Perception of Groups

  • Study by Cacault & Grieder (2019): Examined how group membership affects perceptions of IQ:
    • Enhanced in-group positive bias in assessments of intelligence.
  • Comparison of abilities often favors in-group, regardless of actual differences.

Active Bias Towards Out-Groups

  • Bias generally manifests as a lack of positivity towards out-groups.
  • Higher arousal can incite strong negative emotions towards out-groups (e.g., fear, contempt).

Application of Social Identity Theory

  • Understanding biases can help:
    • Reduce prejudices.
    • Improve intergroup relations and group functioning.

Health and Belonging

  • Increasing focus on the mental health protective role of belonging.
  • Psychological resources gained from group memberships:
    • Social support, meaning, purpose, and worth.
Research on Social Relationships and Health
  • Holt-Lunstad et al. (2010): Meta-analysis findings:
    • Strong social ties correlated with lower mortality risk.
    • Comparison with quitting smoking in health benefits.
Group Membership and Mental Health
  • Sani et al. (2015): Belonging to multiple groups linked to:
    • Lower depression medication usage and reduced reported depression.
Nature of Group Memberships
  • Importance of the type of group memberships:
    • Harmony among identities impacts wellbeing (Brook et al., 2008).
The Social Cure
  • Utilizing social connections to improve health:
    • ‘Social prescribing’ initiatives showing improved wellbeing.
Conclusions
  • Take-home Messages:
    • Need to belong is a fundamental human need.
    • Social identity significantly influences self-perception and group dynamics.
    • Group belonging positively impacts health outcomes.
