Social Influence And Group Processes

The phenomenon where some children are actively singing while others are only moving their legs or not participating at all during a group activity like a school assembly can be explained by Social Loafing.

Social Loafing refers to the tendency of individuals to put less effort into a task when they are part of a group compared to when they are working alone. This occurs because the individual responsibility is diluted when the task is performed collectively. In the context of the assembly, some children might believe that their contribution (singing) is not crucial due to the presence of others, and therefore, they may put in less effort (only moving legs or not singing). This results in uneven participation levels.

The phenomenon described in the question is known as "Social Loafing." This occurs when individuals exert less effort to achieve a goal when they work in a group compared to when they work alone. In the context of the question, when people clap in a large group, each participant tends to put in less effort due to the diffusion of responsibility among the group members, leading to a decrease in the noise output per person.

The other options:

• Social facilitation: Refers to the tendency for people to perform tasks better when they are in the presence of others.
• Social rejection: Involves the feeling of being excluded or ignored by a group.
• Social participation: Means actively engaging and being part of a group or community activities.

Therefore, the correct answer is Social Loafing.

To determine the correct options regarding the concept of 'Balance' in Attitude Change as described by Fritz Heider:

1. Heider's P-O-X triangle theory describes the psychological relationship between three elements: Person (P), Other person (O), and an attitudinal object or topic (X). This statement is confirmed as correct because it's the foundation of Heider's theory, reflected in option (A).
2. In the triangle, P indicates the person whose attitude is being studied, O is another person, and X is the object/topic of attitude. This description is also accurate and matches option (B).
3. Imbalance occurs when the product of the relationships between P-O, O-X, and P-X is negative, leading to possible attitude change to restore balance. Imbalance or balance isn't necessarily about all sides being positive or negative but rather about achieving an overall positive product of relationships. Thus option (C) is correct, capturing the essence of needing a balance in attitudes.
4. Contrary to the statements in options (D) and (E), balance is not determined by whether all sides are positive or negative but by the overall product being positive, balancing the relationships.

Thus, the correct options identifying the core of the balance theory according to Heider are (A), (B) & (C) only as these reflect the accurate propositions of the theory.

Tuckman's model of group development describes the stages that groups typically go through as they form and mature. The stages must be arranged in sequence as follows:

1. Forming (B) - This is the initial stage where the group gets together and members are introduced. There is high dependence on the leader for guidance and direction.
2. Storming (C) - In this stage, members begin to push against the boundaries established in the forming stage. Conflicts arise as individuals start to assert their personalities and power structures start to take shape.
3. Norming (A) - At this point, the group begins to establish norms and roles. There is a greater sense of cohesion as members work towards common goals, and cooperation replaces conflict.
4. Performing (D) - The group reaches a stage where it can function effectively and productively together. Members are motivated and can handle decision-making without supervision.
5. Adjourning (E) - This final stage involves the dissolution of the group as the project is completed and members go their separate ways.

Thus, the correct sequence of stages according to Tuckman's model is (B), (C), (A), (D), (E).

In psychology, group formation is often influenced by various factors such as proximity, similarity, status, and self-esteem needs. When examining why Reena and Rabiya, both dog lovers, are likely to form a group, the most accurate factor is similarity.

Similarity refers to the tendency of individuals to associate with others who share common interests, characteristics, or activities. Since both Reena and Rabiya have a shared interest in dogs, this similarity fosters a connection that is likely to lead to group formation. This principle is rooted in the idea that people prefer to affiliate with others who are like themselves, making their interactions more predictable and enjoyable.

Other potential factors were:

• Proximity: While physical closeness can lead to group formation, it is not the primary reason in this scenario.
• Status: Status similarities or differences may influence group dynamics, but it is not applicable here.
• Self-esteem needs: This entails forming groups to enhance one's self-esteem, but isn't the direct reason for Reena and Rabiya's grouping due to shared interests.

Therefore, the most fitting explanation for their likelihood to form a group is similarity based on their mutual love for dogs.
