The Power of the Situation: Social Influences on Behaviour

13.1 The Power of the Situation: Social Influences on Behaviour

This section explores how social situations and group contexts influence individual behaviour. Key concepts include mimicry, social norms, roles, group dynamics, obedience, the bystander effect, and altruism. Understanding these factors is essential for analyzing how people act in social settings and why they sometimes help or fail to help others.

Situational Influence on Behaviour: Mimicry, Norms, and Roles

Social situations can powerfully shape individual actions through mechanisms such as mimicry, adherence to norms, and the adoption of social roles.

• Mimicry: The unconscious or automatic imitation of others' behaviours, gestures, or expressions. Mimicry can facilitate social bonding and increase likability.

• Norms: Shared expectations or rules about how people should behave in specific situations. Norms guide behaviour and help maintain social order.

• Roles: Sets of behaviours expected of individuals in specific positions within a group or society (e.g., student, teacher, leader). Roles can strongly influence actions, sometimes leading to behaviour that aligns with group expectations rather than personal values.

• Example: The Stanford Prison Experiment demonstrated how quickly individuals adopt roles and conform to associated behaviours, sometimes resulting in extreme actions.

Group Dynamics

Group dynamics refer to the ways in which individuals interact and influence each other within a group context. These dynamics can affect decision-making, conformity, and performance.

• Conformity: Adjusting one's behaviour or thinking to match group norms or expectations. Classic studies by Solomon Asch showed that people often conform to group opinions even when they are clearly incorrect.

• Groupthink: A phenomenon where the desire for harmony or conformity in a group leads to poor decision-making. Group members may suppress dissenting opinions to maintain consensus.

• Social Facilitation: Improved performance on simple or well-learned tasks in the presence of others, but sometimes impaired performance on complex tasks.

• Social Loafing: The tendency for individuals to exert less effort when working in a group compared to when working alone.

• Example: In group projects, some members may contribute less (social loafing), while others may conform to the majority opinion even if they disagree (conformity).

To Act or Not to Act: Obedience, the Bystander Effect, and Altruism

Social psychology examines why people obey authority, help others, or fail to intervene in emergencies.

• Obedience: Following direct commands, usually from an authority figure. Stanley Milgram's experiments showed that people are surprisingly likely to obey authority, even when asked to perform actions conflicting with their personal conscience.

• Bystander Effect: The tendency for individuals to be less likely to help a victim when other people are present. The greater the number of bystanders, the less likely any one person is to help (diffusion of responsibility).

• Altruism: Selfless concern for the well-being of others, often resulting in helping behaviour without expectation of reward.

• Example: The case of Kitty Genovese, where multiple witnesses failed to intervene during an attack, is often cited as an example of the bystander effect.

Working the Scientific Literacy Model: The Bystander Effect

The scientific literacy model encourages critical evaluation of psychological phenomena, such as the bystander effect, by considering evidence, alternative explanations, and real-world applications.

• Key Steps:

  1. Identify the phenomenon (e.g., bystander effect).

  2. Review empirical evidence (e.g., classic studies by Darley and Latané).

  3. Consider situational variables (e.g., ambiguity, diffusion of responsibility, perceived danger).

  4. Apply findings to real-life situations (e.g., emergency response training).

• Example: Research shows that people are more likely to help when they are alone or when they feel personally responsible for intervening.

Module 13.1 Summary

• Social situations exert powerful influences on individual behaviour through mechanisms such as mimicry, norms, and roles.

• Group dynamics can lead to conformity, groupthink, social facilitation, and social loafing.

• Obedience to authority, the bystander effect, and altruism are key topics in understanding why people act (or fail to act) in social contexts.

• Applying the scientific literacy model helps critically evaluate and apply psychological research to real-world issues.
