Self-Help Support Groups01:28

Self-Help Support Groups

59
Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.

In- and Out-Groups

39.1K
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.

Groupthink01:34

Groupthink

44.5K
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...

Group Polarization01:01

Group Polarization

34.4K
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.

Group Therapy01:26

Group Therapy

67
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...

Levels of Communication II: Organizational, Public, and Group Dynamics

2.1K
Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

Area of Science:

  • Social Psychology
  • Organizational Behavior
  • Cognitive Science

Background:

  • Group performance evaluations often depend on perceptions of individual member criticality.
  • Understanding how responsibility attributions influence these perceptions is crucial for motivation and resource allocation.

Purpose of the Study:

  • To investigate the relationship between perceived criticality of group members and responsibility.
  • To develop and test models explaining how task structure and member abilities affect criticality judgments.

Main Methods:

  • Experimental manipulation of group task structures (disjunctive, conjunctive, mixed).
  • Experimental manipulation of individual group member abilities.
  • Development and testing of computational models linking criticality and responsibility.

Main Results:

  • Both task structure and member abilities significantly influence criticality judgments.
  • A model where criticality is defined as anticipated credit, rather than anticipated responsibility for success and failure, best explains the data.
  • Individuals focus on potential contributions to success, disregarding potential contributions to failure.

Conclusions:

  • Perceived criticality is primarily driven by anticipated credit for success, not overall responsibility.
  • This highlights a bias in how individuals attribute importance within groups, focusing on positive contributions.
