Social Influence and Group ProcessesClass 12 Psychology NCERT Solutions

Formal and Informal Groups

• Both formal and informal groups are collections of individuals who interact and can influence member behaviour.
• Both types of groups develop norms or unstated rules that guide behaviour.

• Formation: Formal groups are deliberately created based on specific rules or laws, and their functions are explicitly stated (e.g., a university, an office). Informal groups are not based on rules or laws; they emerge spontaneously from social interaction and relationships.
• Structure: Formal groups have a defined structure with specific roles for each member. Informal groups have a more fluid structure, and roles are not explicitly defined.
• Relationships: In formal groups, relationships are often professional and impersonal. In informal groups, there is a close personal relationship among members.

Ingroups and Outgroups

• Both are social categories that individuals use to define themselves and others.
• The perception of both ingroups and outgroups significantly affects our social lives and interactions.

• Identity: An 'ingroup' is the group to which a person belongs ('we'). An 'outgroup' is any group to which a person does not belong ('they').
• Perception: Members of the ingroup are generally viewed favourably, seen as having desirable traits, and perceived as similar to oneself. Members of the outgroup are often viewed negatively and perceived as different.
• Favoritism: Individuals tend to show preference and loyalty towards their ingroup while often holding biases or negative perceptions against the outgroup.

1. Goal Achievement: My primary motivation was to improve my public speaking and critical thinking skills. The debate club provides a platform to achieve this goal, which would be difficult to attain individually. The group facilitates practice, competition, and collaborative learning.
2. Status and Self-Esteem: The debate club is well-regarded in our school for its success in inter-school competitions. Being a member of this prestigious group provides a sense of recognition and status, which in turn enhances my self-esteem and gives me a positive social identity.
3. Satisfaction of Psychological and Social Needs: Joining the club helped satisfy my need for belongingness. I have formed close friendships with other members who share similar interests. It is a place where I can give and receive attention and feel part of a supportive community.
4. Provide Knowledge and Information: The group is a great source of knowledge on a wide range of topics. Through discussions and research for debates, my worldview has broadened significantly. The group supplements the information I have, as different members bring unique perspectives and knowledge to the table.

1. Forming: The model explains the initial phase of uncertainty and apprehension when members first meet. It helps us understand why members are often polite but hesitant as they try to understand the group's purpose and their place within it.
2. Storming: This stage highlights the inevitability of intragroup conflict. The model shows that disagreements over goals, leadership, and roles are a natural part of group development. Understanding this stage helps us see conflict not as a failure, but as a necessary step towards establishing a clear hierarchy and vision.
3. Norming: The model explains how groups overcome conflict to establish norms and a shared identity. This stage shows the development of cohesion and a positive group identity, where members agree on rules of behaviour.
4. Performing: This stage describes the mature phase where the group structure is stable and accepted. The group is now focused and efficient, working collaboratively towards its goals. This helps us understand when a group is at its peak productivity.
5. Adjourning: For temporary groups, like a project committee, this stage explains the process of disbanding after the task is complete. It acknowledges the end of the group's life cycle.

1. Social Loafing: This is a phenomenon where an individual exerts less effort when working on a collective task than when working alone. Because individual contributions are pooled and not separately evaluated, members may feel less responsible and motivated. This is common in tasks like a tug-of-war, where it is difficult to measure each person's effort.
2. Group Polarisation: Groups tend to make more extreme decisions than individuals would on their own. After discussion, the group's initial position on an issue becomes stronger. This happens because members hear new, persuasive arguments supporting their views, feel their opinions are validated by others (a bandwagon effect), and conform to the perceived ingroup view.
3. Groupthink: In highly cohesive groups, the desire for unanimity can override the realistic evaluation of alternative courses of action. Members may suppress dissenting opinions to maintain harmony, leading to irrational and poor decisions. The group develops an exaggerated sense of its own power and becomes out-of-touch with reality. The text cites the escalation of the Vietnam War by U.S. advisors as an example.

• Making the efforts of each person identifiable: Assign specific tasks to each member so their individual contribution is clear.
• Increasing the pressure to work hard: Make group members committed to the successful performance of the task.
• Increasing the apparent importance or value of a task: Emphasise the significance of the group's goal.
• Making people feel that their individual contribution is important: Show how each member's role is crucial for success.
• Strengthening group cohesiveness: Foster a strong sense of team spirit and belonging, which increases motivation.

• Situation: In a four-person group for a science project, two members were doing most of the research and construction, while the other two contributed very little, assuming their lack of effort would go unnoticed in the final group grade.
• Overcoming it: We addressed this by breaking down the project into distinct parts: research, report writing, model construction, and presentation. Each part was assigned to one member, making their individual contribution identifiable and essential. We set clear deadlines for each part. This made everyone feel that their contribution was important and held them accountable, which significantly reduced the loafing.

• Situation: Our class was responsible for decorating the school grounds for Sports Day. It was a large task, and initially, many students were standing around and chatting, leaving the hard work to a few motivated individuals. The overall task was so large that individual efforts seemed insignificant.
• Overcoming it: To overcome this, our class teacher strengthened group cohesiveness. She initiated a small speech about class pride and the importance of working together to make our school look the best. She then divided the class into smaller, competing teams, each responsible for a specific zone (e.g., entrance, main field, stage). This increased the pressure to work hard and made the task feel more valuable. By making the teams smaller and their goals clearer, individual contributions became more visible, and participation improved dramatically.
