Social Loafing01:37

Social Loafing

36.5K
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,...

Social Psychology and Individual Behavior

24
Social psychology examines how group dynamics, emotions, and cultural influences shape individual actions and decision-making. These elements interact to form behavioral patterns that affect personal choices and social interactions.The Role of Group DynamicsGroups play a crucial role in shaping behavior by reinforcing norms and expectations. Individuals derive a sense of self from group membership, often aligning their behaviors with group norms to maintain social cohesion. For example, an...

Deindividuation

27.8K
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.

Impact of Individuals on a Group

29
In social psychology, the interplay between individuals and groups is a central concern, particularly regarding how individual actions and characteristics influence group processes and outcomes. While much research emphasizes the group's power in shaping individual behavior, it is equally significant to understand how individuals contribute to the functioning, development, and success of groups.Individual Roles in Group Productivity and Decision-MakingIndividuals are not passive participants in...

Self-Presentation: Self-Monitoring and Self-Handicapping

41.0K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Area of Science:

  • Behavioral Psychology
  • Quantitative Analysis
  • Educational Technology

Background:

  • Delay discounting research primarily targets substance use, eating, and gambling behaviors.
  • Procrastination has been under-examined by quantitative behavior analysts despite its prevalence.

Purpose of the Study:

  • To investigate procrastination as a delay discounting behavior in an academic context.
  • To analyze the temporal patterns and individual stability of procrastination among students.

Main Methods:

  • 295 psychology students on an e-learning platform completed four tests with self-selected deadlines.
  • Behavioral data on test completion times were analyzed using hyperbolic functions and lognormal distributions.

Main Results:

  • Most students exhibited procrastination, completing tests close to deadlines, forming a "scalloping" pattern.
  • Individual procrastination levels were stable across tests and negatively correlated with academic grades.
  • Group-level procrastination patterns aligned with a lognormal distribution of individual impulsivity.

Conclusions:

  • Procrastination is a stable behavioral trait linked to delay discounting and impulsivity.
  • Student procrastination significantly impacts academic performance, highlighting the need for behavioral interventions.
  • E-learning platforms provide a viable setting for studying delay discounting and procrastination behaviors.
