Social Influence and Group Processes — NCERT Solutions

Given: Groups have a significant impact on individual behaviour. Two major ways in which groups influence behaviour are Social Facilitation and Social Loafing.

1. Social Facilitation:

• Definition: The tendency for individuals to perform better on simple or well-learned tasks when in the presence of others, compared to when alone.
• Explanation: The mere presence of others creates arousal, which enhances performance on tasks that are easy or familiar. However, for complex or new tasks, the presence of others may impair performance.
• Example: A student who has practised a speech many times will deliver it better in front of an audience. However, a student attempting a new and difficult problem may struggle more when observed.
• Proposed by: Robert Zajonc (1965).

2. Social Loafing:

• Definition: The tendency for individuals to exert less effort when working in a group than when working alone.
• Explanation: When people work in a group, individual contributions are less identifiable, leading to reduced personal accountability. Members assume others will compensate for their reduced effort.
• Example: In a group project, some students may contribute less, assuming others will do the work.
• Proposed by: Ringelmann (rope-pulling experiment).

3. Group Polarisation:

• Groups tend to make more extreme decisions than individuals would make alone. If members lean towards a risky decision, group discussion makes it even riskier (risky shift), and vice versa.

4. Groupthink:

• In highly cohesive groups, the desire for harmony and conformity overrides realistic appraisal of alternatives, leading to poor decision-making.
• Example: A committee may agree on a flawed plan because no one wants to challenge the majority view.

5. Conformity and Compliance:

• Groups exert normative and informational pressure on individuals to conform to group norms, even when the individual privately disagrees.

Conclusion: Groups influence our behaviour both positively (social facilitation, motivation, goal achievement) and negatively (social loafing, groupthink, conformity pressure). Being aware of these influences helps individuals and leaders manage group dynamics more effectively.

Given: Social loafing is the tendency to put in less effort when working in a group. The question asks for strategies to reduce it and personal examples from school.

Strategies to Reduce Social Loafing:

1. Making individual contributions identifiable: When each member's contribution is visible and evaluated separately, people are less likely to loaf. Assigning specific roles and tasks to each member ensures accountability.

2. Setting clear individual goals: Giving each member a specific, measurable goal increases personal responsibility and motivation.

3. Increasing group cohesiveness: When members feel a strong sense of belonging and care about the group's success, they are more motivated to contribute fully.

4. Keeping groups small: In smaller groups, each person's contribution is more noticeable, reducing the tendency to free-ride.

5. Peer evaluation: Allowing group members to evaluate each other's contributions creates social pressure to perform.

6. Emphasising the importance of the task: When members understand that the task is meaningful and their contribution matters, loafing decreases.

7. Rewarding individual as well as group performance: Combining individual and group rewards motivates each member to contribute.

Two Incidents of Social Loafing in School (Model Answer):

Incident 1 — Group Project:
During a science project, our group of five students was assigned to make a working model. Two members did most of the work while the others contributed very little, assuming the active members would complete it.

How we overcame it: Our teacher divided the project into specific sub-tasks and assigned one sub-task to each member. Each student had to present their own part during the evaluation. This made individual contributions identifiable and everyone worked sincerely.

Incident 2 — Cleaning Drive:
During a school cleanliness drive, students were divided into large groups to clean different areas. Many students stood around and let a few enthusiastic members do all the cleaning.

How we overcame it: The class monitor divided the area into smaller sections and assigned two students to each section. Since each pair was responsible for a specific area, everyone participated actively.

Conclusion: Social loafing can be effectively reduced by increasing individual accountability, keeping groups small, and ensuring that each member's contribution is visible and valued.
