Social Psychology Concepts: Group Dynamics, Social Loafing, Deindividuation, and Individual Differences

Group Polarization

Group Polarization is defined as a group-produced exaggeration of members’ preexisting tendencies. This phenomenon has three key features:

1. It refers to the average tendency, not a split within the group.

2. The entire group becomes more extreme in its initial direction.

3. It does not occur if a dissenter is present.

How Group Polarization Occurs

Group polarization happens through two main processes:

1. Social Comparison: This involves viewing extreme positions in a favorable direction as better, driven by normative influence.

2. Mutual Persuasion: Members introduce new, persuasive information and arguments, which is an informational influence.

Groupthink

Groupthink is a phenomenon where group members share such a strong motivation to achieve consensus that they lose the ability to critically evaluate alternative points of view. Historical examples include Pearl Harbor and the Bay of Pigs.

Conditions Leading to Groupthink

1. The group is highly cohesive.

2. The group is isolated from contrary opinions.

3. The group is led by a dominant leader who makes their wishes known.

Symptoms of Groupthink

1. The group begins to feel invulnerable.

2. The group becomes close-minded.

3. The group feels increased pressure toward unanimity.

Social Loafing

Social Loafing is the tendency for people to exert less effort when they pool resources toward a common goal than when they are individually accountable. It often occurs in additive tasks, where each member performs similar duties, and the final product is the sum of all contributions.

Latane et al. (1979) Experiment

In a study by Latane et al. (1979), subjects wore headphones and were blindfolded. They were told they would hear cheering and clapping and were tasked with making the same noise as loudly as possible.

Conditions:

• Control (alone)

• Two-person group

• Four-person group

• Six-person group

The results indicated that sound pressure per person decreased as group size increased.

This can be seen from the plot of the experimental data where the sound pressure $P$ for a group of size $N$ can be modeled approximately:

$P(N) = \frac{P<em>1}{N^k}$ Where $P</em>1$ is the sound pressure exerted by a single individual and 0 < k < 1 is a constant that determines the rate of decay.

Additionally, when examining performance as a percentage of individual performance, it was found that the percent decreases as the group size increases.

Factors that Reduce Social Loafing

Social loafing is less likely to occur when:

1. The contribution of each member is identifiable.

2. The task is challenging, interesting, or meaningful.

3. Group performance is rewarded or punished.

4. The other group members are one’s friends.

Deindividuation

Deindividuation is the loosening of normal constraints on behavior when people are in a crowd or their identity is concealed. This leads to an increase in impulsive and deviant acts.

Conditions Promoting Deindividuation

1. Anonymity

2. Focusing attention away from self

Johnson & Downing (1979) Experiment

In an experiment by Johnson & Downing (1979), subjects were told their task was to recommend an increase or decrease in shock level for another subject (a confederate).

Clothing Conditions:

• KKK robe

• Nurse outfit

Deindividuation Conditions:

• Deindividuation (face covered)

• Control

Results:

The dependent variable was the increased or decreased shock level (up to 3 levels in either direction).

• KKK condition, no hood: $+0.75$

• Nurse condition, no hood: $-0.30$

• KKK condition, hood: $+0.97$

• Nurse condition, hood: $-1.6$

Gergen et al. (1973) Experiment

In an experiment by Gergen et al. (1973), four male and four female subjects were put in a room for one hour with no rules and told they wouldn’t see each other after the study.

Conditions:

• Control (lights on)

• Deindividuation (lights out)

Results:

• Talking: The control condition talked more.

• Touching others: 0% touched others in the control condition; 90% touched others in the deindividuation condition.

• Hugging/kissing: 0% hugged or kissed in the control condition; 50% hugged/kissed others in the deindividuation condition.

Individual Differences and Dispositions

Personality can be described as individual differences in dispositions.

• Individual differences: The study of variation.

• Dispositions: Enduring characteristics of a person.

Dispositions

Dispositions are:

• Carried into situations.

• Socialized.

• Biologically-based.

• In clay, not concrete.

What is Social Psychology?

Social psychology is:

• "The scientific attempt to understand and explain how the thoughts, feelings, & behaviors of individuals are influenced by the actual, imagined, or implied presence of others." (G. Allport)

• "The scientific study of how people think about, influence, and relate to one another" (D. Myers)

• Situationism: The belief that the social situation has the most powerful impact on behavior.

Situations

Situations exert influence on:

• The attitudes we form and change.

• The stereotypes we adhere to or fight against.

• The attraction we feel toward friends/potential mates.

• The help we give and the hurt we dish out.

• The obedience, compliance, and conformity we exhibit.

Social Psychological View of Behavior

1. Limited information processing; many heuristics and biases (automatic).

2. Self-centered and self-aggrandizing.

Group Polarization

Group polarization is defined as a group-produced exaggeration of members’ preexisting tendencies or beliefs. This phenomenon has three key features:

1. It refers to the average tendency of the group members—meaning it reflects the general direction in which group members lean, rather than implying a division or split within the group.

2. The entire group tends to become more extreme in its initial direction after discussing ideas or issues, resulting in stronger opinions and commitments.

3. Group polarization does not occur if a dissenter is present, as the presence of disagreement can provide alternative viewpoints that prevent the extreme convergence of opinions.

How Group Polarization Occurs

Group polarization can happen through two main processes:

1. Social Comparison: This involves members of the group perceiving extreme positions as more socially acceptable or desirable, influenced by normative pressures. Group members compare their beliefs with those of others to gain social approval, leading to a shift towards more extreme views.

2. Mutual Persuasion: Members of the group share new, persuasive information and arguments with each other. This interaction enhances their beliefs through informational influence, where each member learns and feels validated in their views, ultimately promoting a collective movement towards more radical stances.

Groupthink

Groupthink is a psychological phenomenon that occurs when members of a cohesive group prioritize consensus and harmony over critical analysis and dissenting opinions. This often leads to poor decision-making and significant errors. Several historical instances of groupthink include the lack of preparedness evident during the attacks on Pearl Harbor and the flawed decision-making in the Bay of Pigs invasion.

Conditions Leading to Groupthink

The following conditions contribute to the emergence of groupthink:

1. High Cohesion: When group members feel strong ties to one another, they may suppress dissenting opinions to maintain group harmony.

2. Isolation from Contradictory Opinions: Groups that shield themselves from differing perspectives can become overly confident in their decisions.

3. Dominant Leadership: A leader who is vocal about their preferences can stifle alternative viewpoints and discourage critical discussion.

Symptoms of Groupthink

Groupthink manifests through several symptoms that compromise decision-making:

1. Illusion of Invulnerability: Members may develop an inflated sense of confidence, believing that their group is incapable of making mistakes, thereby ignoring risks.

2. Close-mindedness: The group may dismiss any opposing views and avoid contemplating alternative ideas, resulting in a narrow view of possibilities.

3. Pressure Toward Unanimity: Group members may feel pressured to conform to the majority opinion, stifling individual contributions and discussions.

Social Loafing

Social loafing refers to the tendency for individuals to exert less effort when working in a group compared to when they are working alone. This phenomenon is most prevalent during additive tasks, where the group's combined output is the sum of individual efforts, leading to a diffusion of responsibility.

Latane et al. (1979) Experiment

In a pivotal study by Latane et al. (1979), subjects wore headphones and were blindfolded, instructed to produce noise as loudly as possible. The experimental conditions varied by group size:

• Control (Alone)

• Two-person group

• Four-person group

• Six-person group

The results revealed that as group size increased, sound pressure produced per person decreased. This trend is represented in the experimental data indicating that sound pressure $P$ for a group of size $N$ can be modeled approximately by:

$P(N) = \frac{P1}{N^k}$
Where $P1$ is the sound pressure exerted by a single individual and 0 < k < 1 is a constant that determines the rate of decay. Additionally, the percentage of performance relative to individual efforts decreased with increasing group size.

Factors that Reduce Social Loafing

Social loafing is less likely to occur under the following conditions:

1. Identifiable Contributions: When individual contributions are visible, members are more likely to exert effort to avoid social loafing.

2. Task Engagement: Tasks that are perceived as challenging, interesting, or meaningful tend to encourage higher levels of effort from each member.

3. Reward Systems: Group performance being tied to rewards or penalties can motivate individuals to contribute more effectively to group tasks.

4. Friendship: When group members are friends, they are usually more invested in each other's success, decreasing the likelihood of social loafing.

Deindividuation

Deindividuation is the psychological state characterized by a diminished sense of self-awareness and reduced accountability, often occurring in groups or crowds. This can lead to an increase in impulsive and deviant acts, as individuals feel anonymous and unrestrained.

Conditions Promoting Deindividuation

Deindividuation is likely to occur under these conditions:

1. Anonymity: People lose their sense of individuality and accountability when they feel anonymous in a crowd or group context.

2. Focused Attention Away from Self: When the attention is diverted from an individual to the group as a whole, self-regulation can become weakened, encouraging uninhibited behavior.

Johnson & Downing (1979) Experiment

In Johnson & Downing's experiment, subjects were told to recommend shock level adjustments for another participant (a confederate). They were assigned clothing that influenced their behavior:

• KKK Robe Condition

• Nurse Outfit Condition

The deindividuation conditions were:

• Deindividuation (face covered)

• Control

Results showed varied levels of shock application:

• KKK condition, no hood: $+0.75$

• Nurse condition, no hood: $-0.30$

• KKK condition, hood: $+0.97$

• Nurse condition, hood: $-1.6$

Gergen et al. (1973) Experiment

In another study, Gergen et al. (1973) observed subjects in a room for one hour with no rules while telling them they wouldn’t see each other after the study. The conditions were:

• Control (lights on)

• Deindividuation (lights out)

Results indicated significant differences in behavior:

• Talking: The control group conversed more.

• Touching: 0% in the control group gestured towards others, whereas 90% did in the deindividuation condition.

• Hugging/Kissing: 0% in the control group engaged in hugging or kissing; 50% did so in the deindividuation condition.

Individual Differences and Dispositions

Personality can be understood as the study of individual differences in dispositions, which are considered as enduring characteristics of a person.

1. Individual Differences: This involves the examination of variability among individuals in psychological traits.

2. Dispositions: They are intrinsic qualities that can impact behaviors and ways of thinking.

Dispositions

Dispositions are notable for several reasons:

1. They are carried into various situations.

2. They are shaped through socialization processes and experiences.

3. Some dispositional characteristics may have biological roots.

4. They are flexible and subject to change, as indicated by the metaphor 'in clay, not concrete.'

What is Social Psychology?

Social psychology can be defined as:
"The scientific attempt to understand and explain how the thoughts, feelings, and behaviors of individuals are influenced by the actual, imagined, or implied presence of others." (G. Allport)
"The scientific study of how people think about, influence, and relate to one another." (D. Myers)

Furthermore, situationism asserts that the social context exerts the strongest influence on behavior by affecting:

• Attitudes formation and alteration.

• Stereotypes adhered to or resisted.

• Attraction towards friends or potential mates.

• The help provided versus the harm inflicted.

• Levels of obedience, compliance, and conformity exhibited by individuals in social contexts.

Social Psychological View of Behavior

The social psychological framework suggests that:

1. Information processing is limited, leading individuals to rely on heuristics and cognitive biases, often resulting in automatic responses.

2. People tend to exhibit self-centered and self-aggrandizing behaviors, influenced by their motivations and social interactions.
