Social Loafing01:37

Social Loafing

35.4K
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,...

Groupthink

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...

In- and Out-Groups

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.

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...

Social Facilitation

32.3K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Area of Science:

  • Social Cognitive Theory
  • Organizational Psychology
  • Team Performance

Background:

  • Social cognitive theory posits that group efficacy beliefs enhance performance.
  • Emerging research suggests a more complex relationship between group efficacy and performance.
  • Understanding boundary conditions is crucial for accurate theoretical application.

Purpose of the Study:

  • To investigate the boundary conditions of the group efficacy-performance relationship.
  • To examine how member competency moderates the link between group efficacy and performance.
  • To identify specific conditions, like bottlenecks, that may invert this relationship.

Main Methods:

  • Data collected from 389 employees across 41 work groups in a South Korean manufacturing company.
  • Analysis focused on the correlation between group efficacy and group performance.
  • Group competency and bottlenecks were operationalized and statistically analyzed.

Main Results:

  • A positive correlation was found between group efficacy and group performance.
  • This positive relationship was stronger when group members were generally less competent.
  • Bottlenecks (minimum competency) in efficacious groups were associated with a negative efficacy-performance link.

Conclusions:

  • Group efficacy is a significant predictor of group performance.
  • Member competency acts as a crucial moderator, with lower competency amplifying the positive effect.
  • The presence of bottlenecks can disrupt the positive efficacy-performance dynamic, highlighting the importance of skill distribution.
