Answer (Section A — ~450 words):​

Pro-social behaviour refers to voluntary actions intended to benefit another person or group — sharing, cooperating, comforting, and helping. Altruism is the purest form: helping motivated by concern for another's welfare, with no expectation of personal gain. Social psychology has extensively studied why people help (and why they do not).

Latané and Darley's 5-Step Model (1970): Latané and Darley's research into the Kitty Genovese murder (1964) — where 38 bystanders failed to help — produced a sequential decision model of emergency helping. A person will help only if they successfully navigate five steps:

  1. Notice the event — Preoccupation, distraction, or hurry reduce noticing.
  2. Interpret as emergency — Pluralistic ignorance: when others appear unconcerned, individuals interpret the situation as non-emergency. Ambiguity inhibits helping.
  3. Assume responsibility — Diffusion of responsibility: the more bystanders present, the less personal responsibility each individual feels.
  4. Possess requisite skills — Helping requires the belief that one has the competence to help effectively.
  5. Decide to implement help — Evaluation apprehension: fear of embarrassment for intervening unnecessarily inhibits help.

Theories of Pro-social Behaviour:

Empathy-Altruism Hypothesis (Batson, 1991): Perspective-taking produces empathic concern (other-focused emotion) which motivates genuinely altruistic helping — regardless of whether the helper will personally benefit. Batson's research demonstrated that when empathy was induced, participants helped even when escape was easy and personal benefit minimal. This is the strongest evidence for genuine altruism.

Negative-State Relief Model (Cialdini): People in a negative mood help to alleviate their own distress — helping is ultimately self-motivated. The sadness-induced helping effect: sad people help more, but only when helping will improve their mood.

Social Exchange Theory: Helping behaviour is motivated by the balance of costs and benefits. People help when the rewards (esteem, reciprocity, avoiding guilt) outweigh the costs (time, danger, effort).

Kin Selection (Evolutionary): Hamilton's inclusive fitness theory predicts that helping behaviour should be greatest towards genetic relatives, because it increases the helper's own genetic representation in future generations. Supportive evidence comes from studies of grandparental investment and risk-taking.

Norm of Social Responsibility: Cultural norms prescribe helping those in need who depend on us — children, elderly, and people unable to help themselves. Norms of reciprocity (return favours) and equity (restore fairness) also motivate helping.

Factors Affecting Helping: Situational factors: number of bystanders (diffusion of responsibility), clarity of need, time pressure. Victim characteristics: similarity to helper, attractiveness, perceived deservingness. Helper characteristics: empathy, positive mood, feeling competent, prior commitment to helpfulness.

In conclusion, pro-social behaviour is determined by a complex interplay of situational, motivational, and personality factors. Increasing individual responsibility, reducing pluralistic ignorance, and cultivating empathy are effective strategies for promoting helping.

📝 Other Questions​

Define altruism and the bystander effect (Section C — ~100 words)​

Altruism is behaviour that benefits another person at some cost to the helper, motivated purely by concern for the other's welfare rather than personal gain. It is the hallmark of genuinely pro-social motivation.

Bystander Effect (Latané and Darley, 1968): The presence of multiple bystanders reduces each individual's likelihood of helping in an emergency. Two mechanisms operate: diffusion of responsibility (each bystander feels less personally responsible when others are present) and pluralistic ignorance (each bystander looks to others' calm reactions to judge whether the situation is an emergency). The more bystanders, the less likely any single one will intervene.

💡 Exam Tips​

  • Section A: Define pro-social behaviour → Latané-Darley model (5 steps, each explained) → theories (name 3–4) → factors → conclusion.
  • Always mention the Kitty Genovese case when discussing bystander effect — it provides powerful historical context.
  • Distinguish altruism (Batson) from self-interested helping (Cialdini's negative-state relief) — this contrast is frequently tested.
