Prosocial Behaviour: Comprehensive Study Notes

Prosocial Behaviour: Comprehensive Study Notes

  • Definition and scope

    • Prosocial behaviour is defined as doing something that is good for other people or for society as a whole. \text{Prosocial behaviour} = \text{actions that benefit others or society}

    • Prosocial behaviour includes actions that respect others or help society function; it builds relationships. Antisocial behaviour is the opposite (acts that harm others or society).

    • Daily-life examples: obeying traffic laws (e.g., stopping at a stop sign), not cheating on quizzes, paying for goods/services, volunteering, helping an elderly person cross the street, assisting a friend in need.

    • Prosocial behaviours include: \text{Cooperation}, \text{Forgiveness}, \text{Obedience}, \text{Conformity}, \text{Trust}

    • Rule of law: when society members respect and follow rules; crucial for social functioning.

    • The rule of law and prosocial norms support the stability and cohesion of communities.

  • Norms and motivations for helping

    • Born to reciprocate

    • Reciprocity: the obligation to return in kind what another has done for us. Folk wisdom: "You scratch my back, and I’ll scratch yours." Reciprocity norms are found across cultures.

    • Reciprocity norms can apply even when you did not ask for the favour; you may feel obligated to return it when given a present or a gesture.

    • Gratitude: a positive emotion from benefiting from someone’s costly, voluntary action. \text{Gratitude} = \text{positive emotion from benefiting from others' benevolent actions}

    • Fairness norms

    • Norms are standards established by society about typical or expected behaviour.

    • Equity: benefits proportional to contribution. \text{Equity} = \text{benefits} \propto \text{contribution}

    • Equality: everyone gets the same amount. \text{Equality} = \text{uniform distribution of benefits}

    • Under-benefited vs. Over-benefited: getting less or more than deserved, respectively.

    • Reciprocity, gratitude, fairness, and cooperation interplay to shape helping behaviour.

    • Review concept chart (reciprocity, gratitude, norms, equity, equality).

  • Role of morality in prosocial behaviour

    • Morality is a key factor in prosocial behaviour; all known human societies have moral rules about right vs. wrong.

    • Moral rules encourage actions that benefit the social group, often restraining selfish impulses.

    • Time-of-day effects: a morning morality effect suggests higher virtue early in the day (linked to self-control) and increasing immoral actions later as self-control resources deplete.

    • Moral conflicts arise when tempted to do something morally wrong for personal gain.

    • Distinguish between:

    • Moral reasoning: using logical deductions to judge right vs. wrong based on abstract principles.

    • Moral intuitions: automatic judgments driven by emotion.

    • Five moral foundations (predominant in political ideology discussions):

    • 1) Disapproval of hurting others

    • 2) Fairness

    • 3) Respect for legitimate authority

    • 4) Loyalty to one’s group

    • 5) Purity and sanctity

    • Summary: morality helps explain why people restrain selfish impulses and engage in prosocial acts; moral reasoning vs intuition illustrate different pathways to moral judgments.

  • Types of prosocial behaviours: cooperation, forgiveness, obedience, conformity, trust

    • Cooperation: Working together for mutual or reciprocal benefit. Prisoner’s Dilemma and non-zero-sum vs zero-sum games illustrate cooperation dynamics.

    • Forgiveness: Ceasing to feel anger or seek retribution after hurt or betrayal; important for repairing relationships.

    • Obedience: Following orders from an authority figure; often essential for functioning in groups, but can lead to immoral outcomes in extreme cases (Milgram).

    • Conformity: Going along with the crowd; can promote social harmony and cooperation but may lead to mindless following.

    • Trust: Confidence that others will provide benefits or not harm you, even if tempted to act otherwise; foundational for cooperative cultures.

    • Review concept chart: includes definitions and links between the concepts above (e.g., Prisoner’s Dilemma, non-zero-sum vs zero-sum, altruistic punishment).

  • The Milgram obedience study and its influence

    • Background and purpose

    • Milgram explored obedience to authority in the context of World War II atrocities; asked how ordinary people could harm others under instruction.

    • Procedure (baseline study)

    • Participants were instructed to act as a teacher delivering electric shocks to a learner for mistakes; shocks increased in 15-volt increments from a mild shock to severe and potentially dangerous levels (up to 450\text{ volts}). The learner (a confederate) was not actually shocked, but produced screams to simulate distress.

    • Verbal prods were used by the experimenter to compel continued shocks.

    • Later variations showed the proximity of the learner and the setting influenced obedience.

    • Key findings

    • The majority of participants delivered extreme shocks under orders; baseline figure: 62.5\% continued to the maximum shock level.

    • Replications (e.g., Burger, 2009) found nearly identical results but halted at lower voltages for ethical reasons; about 70\% continued beyond the point of initial distress.

    • Interpretations and implications

    • Obedience can be strong in the face of legitimate authority, even when actions conflict with personal morals.

    • Milgram’s work highlighted situational factors over dispositional traits in many obedience scenarios.

    • Obedience has prosocial benefits in organizing group life, but it can be dangerous when authorities issue immoral commands.

    • Criticisms and ongoing debates

    • Ethical concerns about participant distress; debates about external validity and cultural generalizability; later work explored individual differences (e.g., agreeableness, political orientation).

  • Motives for helping: explanations and motives

    • Evolutionary explanations

    • Kin selection: Helping relatives to ensure the survival of shared genes. Help tends to be strongest for close kin (e.g., siblings over nephews or cousins).

    • Example: Parent-child helping may be more likely than child-parent helping due to gene propagation differences.

    • Empathy and altruism

    • Empathy: emotional resonance with another’s distress; seeing someone suffer triggers empathic concern.

    • Two broad motives for helping: altruism (helping to increase another’s welfare) and egoism (helping to increase one’s own welfare).

    • Altruism vs egoism (historical debate)

    • Auguste Comte described two forms of helping: egoistic (help for personal gain) and altruistic (help to increase another’s welfare without expectation of return).

    • Empathy-altruism hypothesis: high empathy motivates helping to reduce another’s distress; low empathy may lead to helping to reduce one’s own distress or escape the situation.

    • Experimental evidence

    • High-empathy condition: participants traded places with Elaine, even when escape was easy or difficult, supporting empathy-driven altruism.

    • Low-empathy condition: participants helped mainly when escape was difficult, indicating egoistic helping under certain conditions.

    • Key terms

    • Kin selection, Empathy, Egoistic helping, Altruistic helping, Empathy-altruism hypothesis.

  • Who is most likely to help and who is most likely to receive help

    • Key determinants of helping tendencies

    • Helpful personality, Similarity, Gender, Appearance (beautiful victims), Belief in a just world, Mood and emotion.

    • Research highlights

    • People show greater willingness to help those who are similar, and to help attractive individuals; the latter is sometimes explained via perceived need and status cues.

    • Belief in a just world can influence helping: people may help only if they perceive the recipient as deserving.

    • Receiving help

    • Females are more likely to receive help than males, regardless of the helper’s gender, across various contexts.

    • Gender differences in helping

    • Men are more likely to help in public, emergency, or high-risk situations; women tend to help more in family settings and in sustained volunteering.

    • Summary: helping is influenced by personality, social similarity, gender norms, and perceived deservingness.

  • Five steps in bystander intervention

    • Kitty Genovese case and bystander effect

    • In emergencies, presence of others reduces likelihood of helping; group contexts can impede individual action.

    • The five steps to helping (Darley & Latané)

    • Step 1: Notice something is happening. Obstacles include distraction and being in a hurry; presence of others increases distraction.

    • Step 2: Interpret the event as an emergency. Obstacles include pluralistic ignorance: others’ inaction leads to misinterpretation that nothing is wrong; ambiguity about the emergency.

    • Step 3: Take responsibility for providing help. Diffusion of responsibility: the sense that someone else will help when others are present.

    • Step 4: Know how to help. Obstacles include lack of competence or fear of being ill-equipped to help.

    • Step 5: Provide help. Obstacles include audience inhibition (fear of looking foolish) and cost to helping relative to benefits.

    • Pathways to action

    • The presence of a crowd increases diffusion of responsibility, which reduces helping likelihood. Direct instruction and clear assignment of responsibility can increase helping.

  • Ways to increase helping and prosocial engagement

    • Public settings: reduce uncertainty about who is responsible and what to do; identify a specific helper to approach.

    • Provide helpful models: live, filmed, or media-based models that demonstrate helping behavior increase subsequent helping.

    • Volunteering: planned, long-term engagement to help others; increases prosocial behavior and social connectedness.

    • Teach moral inclusion: expand ingroup boundaries to include all humanity; reduces outgroup hostility and increases helping.

    • The Identification With All Humanity scale: measures the extent to which people identify with all humanity; higher identification correlates with greater prosocial behavior, empathy, and humanitarian concern.

    • Publicizing and modeling prosocial behavior can foster a culture of helping and cooperation.

  • Reciprocity, fairness, and belonging in social life

    • Reciprocity and fairness norms shape everyday interactions and expectations for mutual aid.

    • Equity vs equality: fairness requires considering contribution and needs; equality distributes benefits evenly regardless of contribution.

    • Norms of fairness and cooperation contribute to the stability of social groups and reduce conflict.

    • The link between fairness and mental health: perceiving fairness in social exchanges reduces negative outcomes such as depression from feeling exploited.

  • Cooperation, punishment, and social enforcement in groups

    • Cooperation as a foundation of culture

    • Cooperation allows groups to achieve outcomes greater than the sum of individual efforts; it is built on trust and shared norms.

    • Prisoner’s Dilemma and non-zero-sum games

    • In the Prisoner’s Dilemma, mutual cooperation yields better outcomes than defection; however, if one party defects while the other cooperates, defection yields the best payoff for the defector.

    • Tit-for-tat strategy: start with cooperation and then mimic the other’s previous move; promotes cooperation when both parties aim for mutual benefit.

    • Non-zero-sum games: both participants can win; zero-sum games: one’s gain is the other’s loss (e.g., poker, tennis).

    • Altruistic punishment and social enforcement

    • People are willing to incur costs to punish rule-breakers to maintain cooperation; gossip serves as a social mechanism to communicate trustworthiness and enforce norms.

    • Gender, communication, and cooperation

    • Communication improves cooperation; when partners discuss strategies, cooperation increases.

  • Trust and social exchange

    • Trust is the belief that strangers will act in reliable and beneficial ways; trust is essential for economic and social interactions (e.g., trust game).

    • Trust is higher for individuals with self-control and those who demonstrate dependable behavior; loneliness reduces trust.

    • Pronounced effects of name pronounceability on trust and perceived reliability demonstrate social-cognitive biases in forming trust.

    • Trust is slow to build and quick to unravel; betrayals dramatically reduce subsequent trust in long-running interactions.

  • Obedience, conformity, and the social life

    • Obedience (to authority) can be prosocial, enabling large groups to function (e.g., teams, military, organizations); Milgram’s findings highlight the potential for immoral action under legitimate authority.

    • Conformity supports functioning in large groups but can lead to dysfunctional or harmful behaviors if norms promote harmful actions.

    • Norms, laws, and rules help people know when to cooperate and how to act in public and private life; violations can undermine social order unless corrected.

  • Morality foundations, politics, and everyday judgments

    • Moral foundations often align with political orientation: liberals tend to emphasize disapproval of hurting and fairness; conservatives tend to emphasize all five foundations (including authority, loyalty, purity).

    • Subtle cues (e.g., purity cues) can influence political opinions and moral judgments in seemingly unrelated domains (e.g., hand sanitizer cues shifting political views).

  • Examples of notable bystander and cooperative phenomena

    • Real-world examples of bystander behavior and cooperative actions (e.g., crowds lifting a train to free a trapped person; rescuers and volunteers in flood situations).

    • Prosocial behaviour can be contagious, spreading through groups via social influence and norms.

  • Random acts of kindness and altruistic personality

    • Random acts of kindness are spontaneous acts intended to help others without expectation of reward.

    • Altruistic personality factors include high ethical values, sense of equity, empathy, and a bias toward universal human welfare.

    • Self-report altruism scales and cross-cultural studies suggest altruism is widespread and has a potential genetic component; similarity and ingroup/outgroup dynamics influence helping behavior.

  • Key formulas and definitions to remember

    • Equity: \text{Benefit}i \propto \text{Contribution}i

    • Equality: \text{Benefit}_{i} = \frac{\text{Total Benefit}}{n}

    • Non-zero-sum vs Zero-sum: Non-zero-sum allows mutual gains; Zero-sum sums to zero across participants. \text{Non-zero-sum} \rightarrow \text{Mutual Gain}, \quad \text{Zero-sum} \rightarrow \text{Gain Loss trade-off}

    • Prone to diffusion of responsibility: when multiple bystanders are present, individual responsibility decreases. If you are alone, the responsibility is 100%; with two people, it is about 50% each; with n people, each has 100%/n responsibility.

Test-yourself prompts (selected, representative items)

  • The norm that produces helping across a wide range of settings is the ____ personality.

    • a altruistic

    • b egoistic

    • c

  • When it comes to receiving help, males are more likely to help ____ and females are more likely to help ___.

    • b believe in a just world

    • c feel over-benefited

  • The five steps to helping in an emergency are: Notice, Interpret, Take responsibility, Know how to help, Provide help. The major obstacles to Step 2 include pluralistic ignorance; to Step 3 include diffusion of responsibility; to Step 4 include lack of competence; to Step 5 include audience inhibition. True/False statements for practice:

    • The bystander effect is stronger as the number of witnesses increases. (True)

    • Diffusion of responsibility increases the likelihood of helping. (False)

    • In emergencies, public settings can increase helping because people are more concerned with social approval. (True)

Summary: what makes us human in prosocial terms

  • Humans are cultural animals with a strong inclination to help others beyond kin. This is supported by evidence across cultures and ages (e.g., toddlers helping adults, cross-cultural prosocial acts).

  • Rule following, cooperation, reciprocity, and compassion are central to human social life and the functioning of large communities.

  • Obedience and conformity are not inherently bad; when aligned with moral principles and positive norms, they support social order; when misused, they can produce harm as highlighted by Milgram’s studies.

  • Empathy and moral reasoning together guide prosocial behaviour, with empathy often driving altruistic actions, while reasoning helps justify moral judgments in complex situations.

  • Final thought: prosocial behaviour is a multi-faceted phenomenon arising from evolutionary pressures, social norms, moral cognition, and emotional processes; it underpins the stability and advancement of human societies.
