Unit 11 Overview: Prosocial Behavior and Altruism
11.1 Factors Influencing Helping Behavior
11.2 Theories of Altruism and Prosocial Behavior
11.3 Bystander Effect and Intervention

The bystander effect shows how people are less likely to help in emergencies when others are around. This happens because responsibility feels spread out, and we look to others for cues on how to act. It's a key part of understanding group behavior in crises.

Knowing about the bystander effect helps us see why people might not step up when needed. By breaking down the decision-making process and looking at real-life examples, we can find ways to overcome this tendency and encourage more helping behavior.

Bystander Effect and Social Influence

Understanding the Bystander Effect

  • Bystander effect describes the phenomenon where individuals are less likely to offer help in an emergency when other people are present
  • Occurs due to the presence of others diluting individual responsibility to act
  • Inversely related to the number of bystanders present in a given situation
  • First identified and researched by social psychologists John Darley and Bibb Latané in 1968
  • Manifests in various settings (emergencies, accidents, crimes)

Psychological Mechanisms Behind Bystander Behavior

  • Diffusion of responsibility spreads the perceived obligation to help across all present individuals
  • Results in each person feeling less personally responsible for taking action
  • Increases with larger groups, leading to decreased likelihood of intervention
  • Pluralistic ignorance causes individuals to misinterpret others' inaction as a sign that help is not needed
  • Leads to a collective misunderstanding of the situation's severity
  • Can result in no one taking action, even when help is urgently required

Social Influences on Bystander Behavior

  • Social influence shapes individual behavior in group settings
  • Includes conformity to perceived group norms and expectations
  • Can lead to inaction if others appear unconcerned or uninvolved
  • Audience inhibition prevents individuals from intervening due to fear of embarrassment or social judgment
  • Concerns about appearing foolish or overreacting can override the impulse to help
  • More pronounced in situations with ambiguous signs of distress

Factors Affecting Bystander Intervention

Situational Factors Influencing Intervention

  • Bystander intervention refers to actions taken by witnesses to help in emergency situations
  • Situational ambiguity affects the likelihood of intervention
  • Clear emergencies (visible injuries, explicit calls for help) more likely to prompt action
  • Ambiguous situations (unclear distress signals, subtle signs of trouble) often lead to delayed or no intervention
  • Environmental factors such as lighting, noise levels, and physical barriers can impact intervention likelihood
  • Time pressure and perceived urgency of the situation influence decision-making processes

Decision-Making Process in Bystander Intervention

  • Latané and Darley's decision model outlines five steps bystanders go through before intervening:
    1. Notice the event
    2. Interpret the situation as an emergency
    3. Accept personal responsibility
    4. Decide how to help
    5. Implement the helping behavior
  • Each step presents potential barriers to intervention
  • Failure at any stage can result in non-intervention
  • Model helps explain why bystanders may not act even in clear emergencies

Historical Context and Real-World Applications

  • Kitty Genovese case in 1964 sparked initial research into the bystander effect
  • Genovese was murdered in New York City, allegedly while multiple witnesses failed to intervene
  • Initial reports of 38 witnesses were later disputed, but the case remains influential in psychology
  • Subsequent research revealed complexities in witness behavior and reporting
  • Case highlights importance of understanding bystander psychology in real-world scenarios
  • Led to development of emergency reporting systems and increased focus on community responsibility

Key Terms to Review (16)

Groupthink: Groupthink is a psychological phenomenon where the desire for harmony and conformity in a group leads to irrational or dysfunctional decision-making. It often results in a loss of individual critical thinking as group members prioritize consensus over the quality of their decisions, affecting various aspects of social judgment, memory, influence, group dynamics, and cultural behaviors.
Social Influence Theory: Social influence theory is a psychological framework that explores how individuals change their thoughts, feelings, or behaviors as a result of real or imagined pressure from others. This theory sheds light on various dynamics such as conformity, obedience, and group behavior, revealing the powerful role that social contexts play in shaping individual actions. By understanding these influences, we can better grasp how people navigate social situations and the factors that encourage or discourage conformity and intervention.
Situational ambiguity: Situational ambiguity refers to a lack of clarity or certainty in a social situation, which can lead individuals to be unsure about how to respond or what actions to take. This uncertainty can significantly influence behavior, often resulting in conformity or non-intervention, as people look to others for cues on how to act. In social contexts where the appropriate response is unclear, individuals may rely on group dynamics or the behavior of others to guide their actions.
Victim blaming: Victim blaming refers to the phenomenon where the victim of a crime or harmful act is held partially or fully responsible for the harm they experienced. This mindset can lead to a misunderstanding of the true nature of the situation, often shifting focus away from the perpetrator's actions and placing undue blame on the victim instead. It plays a significant role in social contexts, impacting how society perceives and responds to victims of violence or wrongdoing.
Egoism: Egoism is a philosophical and ethical theory that suggests individuals act in their own self-interest as the primary motivation for their actions. It highlights the importance of self-preservation and personal gain, often contrasting with altruistic behaviors, where individuals act for the benefit of others. In the context of social interactions, egoism can influence how people decide whether or not to intervene in emergencies, impacting responses to situations involving bystanders.
Cultural Norms of Intervention: Cultural norms of intervention refer to the shared expectations and rules within a society that dictate how individuals should respond to emergencies or crises, particularly regarding helping behavior. These norms influence whether bystanders will step in during a situation requiring assistance and can vary significantly across different cultures, impacting the likelihood and nature of intervention. Understanding these norms is crucial for analyzing the bystander effect, where individuals may be less likely to help when others are present due to social influences.
Kitty Genovese Case: The Kitty Genovese case refers to the tragic murder of Kitty Genovese in 1964, which became a pivotal event in understanding the bystander effect. This case highlighted how a large number of witnesses failed to intervene or even call for help during her assault, leading to widespread public discussion about the phenomenon where individuals are less likely to offer help in emergencies when others are present. It raised awareness about the psychological barriers that can prevent people from acting during critical situations.
Pluralistic Ignorance: Pluralistic ignorance refers to a psychological phenomenon where individuals mistakenly believe that their own thoughts, feelings, or behaviors are different from those of the group, leading them to conform to perceived norms rather than expressing their true opinions. This often occurs in situations where people are unsure about what is appropriate, especially in emergency situations or when deciding whether to help someone in need, impacting the likelihood of intervention and social influence.
Darley and Latané's Experiments: Darley and Latané's experiments are foundational studies in social psychology that demonstrated the bystander effect, where individuals are less likely to help a victim when others are present. The experiments highlighted the diffusion of responsibility phenomenon, showing how the presence of more people can lead to decreased likelihood of intervention during emergencies. These findings are crucial for understanding how social dynamics impact helping behavior in critical situations.
Audience inhibition: Audience inhibition refers to the reluctance of individuals to act in a prosocial manner when they are aware of being observed by others. This phenomenon occurs when individuals feel that their actions might be judged or criticized, leading them to hold back from intervening in situations that require help or support. It connects strongly to the social dynamics at play in both altruistic behavior and the bystander effect, illustrating how the presence of others can significantly impact personal decision-making.
Diffusion of Responsibility: Diffusion of responsibility is a social phenomenon where individuals feel less compelled to take action in emergencies when they believe that others are present. This reduction in personal accountability can lead to inaction, particularly in situations that require assistance or intervention, as people assume someone else will step in. Understanding this concept helps explain how group dynamics can influence helping behavior and the likelihood of intervention during critical moments.
Bystander effect: The bystander effect is a social psychological phenomenon where individuals are less likely to offer help to a victim when other people are present. This occurs due to diffusion of responsibility, where each bystander feels less compelled to take action because they assume someone else will intervene. The presence of others can lead to a decreased likelihood of prosocial behavior, connecting the concept to altruism, social influence, and the various factors that affect helping behavior.
Empathy: Empathy is the ability to understand and share the feelings of another person, which involves both emotional resonance and cognitive awareness. This skill allows individuals to connect with others on a deeper level, fostering compassion and social bonding. It plays a crucial role in human interactions by influencing behaviors related to helping, relationship maintenance, and reducing negative social attitudes.
Moral reasoning: Moral reasoning refers to the cognitive process individuals use to determine what is right or wrong, guiding their ethical decision-making and behavior. This process is influenced by personal values, social norms, and cultural beliefs, shaping how individuals react to moral dilemmas. It plays a crucial role in understanding altruism and prosocial behavior, as well as how people decide whether to intervene in emergencies or help others in need.
Altruism: Altruism refers to the selfless concern for the well-being of others, often leading individuals to engage in prosocial behaviors that benefit others at a personal cost. This concept is crucial for understanding how and why people help one another, influencing theories about the motivations behind such behaviors, the dynamics of bystander intervention, and the various factors that affect an individual's willingness to offer assistance in different situations.
Social Loafing: Social loafing is the tendency for individuals to put forth less effort when working in a group compared to when they are working alone. This phenomenon often occurs because people feel less accountable in a group setting, leading them to rely on others to do the work. As a result, social loafing can impact group dynamics and overall performance, influencing aspects such as memory recall, decision-making processes, and leadership effectiveness.
