Reviewing Prosocial Behaviour
Prosocial behaviour is a fundamental aspect of human interaction that helps society function smoothly. This session will help you consolidate your understanding of why people help others and what factors influence helping behaviour.
Key Definitions:
- Prosocial behaviour: Actions that benefit others, such as helping, sharing, donating, co-operating and volunteering.
- Altruism: Helping others with no expectation of personal gain or reward.
- Bystander effect: The phenomenon where individuals are less likely to offer help in an emergency when other people are present.
💡 Why Study Prosocial Behaviour?
Understanding prosocial behaviour helps psychologists explain:
- Why people help others even at personal cost
- How to encourage more helping in society
- Why some people help in emergencies while others don't
- How to design environments that promote cooperation
📖 Exam Tips
For high marks in exams:
- Always use psychological terminology correctly
- Link explanations to specific studies
- Evaluate theories by discussing strengths and limitations
- Consider real-world applications of prosocial research
Explanations of Prosocial Behaviour
Psychologists explain prosocial behaviour using three main approaches: biological, psychological and social.
Biological Explanations
These focus on how evolution and genetics might explain helping behaviour.
🌈 Kin Selection Theory
We're more likely to help relatives who share our genes. This helps ensure our genetic material survives into the next generation. For example, parents making sacrifices for their children.
Evidence: Burnstein et al. (1994) found people were more likely to help close relatives than distant ones, especially in life-or-death situations.
👪 Reciprocal Altruism
We help others with the expectation they'll help us in the future. This creates mutually beneficial relationships that aid survival.
Evidence: Trivers (1971) observed this behaviour in many species, including humans, where individuals remember and reciprocate helpful acts.
Evaluation of Biological Explanations
Strengths: Explains universal helping patterns across cultures; supported by animal studies showing similar behaviours.
Limitations: Doesn't fully explain helping strangers or anonymous donations; overlooks cultural differences in helping behaviour.
Psychological Explanations
These focus on internal mental processes that motivate helping.
🙂 Empathy-Altruism Hypothesis
Feeling empathy for someone in need creates a genuine desire to help them, regardless of personal benefit.
Evidence: Batson's studies showed people who felt empathy helped others even when they could easily avoid doing so.
😒 Negative State Relief Model
We help others to reduce our own negative feelings (like guilt or sadness) that arise when we see someone suffering.
Evidence: Cialdini found people in sad moods were more likely to help if they believed helping would improve their mood.
Case Study Focus: Batson's Empathy Experiments
Batson et al. (1981) conducted experiments where participants watched a person receiving electric shocks. Those who felt high empathy offered to take the shocks themselves, even when they could easily leave the situation. This suggests genuine altruism exists, driven by empathy rather than selfish motives.
Social Explanations
These focus on how external factors and social learning influence helping behaviour.
👥 Social Norms
Cultural rules that guide behaviour, including:
- Reciprocity norm: Help those who help you
- Social responsibility norm: Help those who need it
🏫 Social Learning
We learn to help by:
- Observing helpful role models
- Being rewarded for helping
- Seeing others rewarded for helping
🛠 Situational Factors
External circumstances like:
- Number of bystanders present
- Clarity of the emergency
- Time pressure and convenience
The Bystander Effect
One of the most studied phenomena in prosocial behaviour is the bystander effect, which helps explain why people sometimes fail to help in emergencies.
Case Study Focus: Kitty Genovese (1964)
Kitty Genovese was murdered outside her apartment in New York while reportedly 38 witnesses failed to intervene or call police. This case inspired research into the bystander effect, although later investigations revealed the original reports were exaggerated. Nevertheless, it sparked important research into why people don't always help in emergencies.
Factors Affecting Bystander Intervention
Latané and Darley (1970) proposed a five-step decision model explaining why bystanders may fail to help:
👀 The Bystander Decision Model
- Notice the event - You must first be aware something is happening
- Interpret as an emergency - You must recognise it requires help
- Take responsibility - You must feel personally responsible to act
- Know how to help - You must have the skills to assist
- Implement the help - You must actually perform the helping behaviour
Failure at any step can prevent helping behaviour.
🔎 Key Research Findings
- Diffusion of responsibility - As the number of bystanders increases, individual responsibility decreases
- Pluralistic ignorance - Looking to others for cues about how to interpret an ambiguous situation
- Audience inhibition - Fear of embarrassment if intervention is inappropriate
Darley and Latané (1968) found 70% of alone participants reported smoke filling a room, compared to just 10% when in groups of three.
Applying Your Knowledge
Understanding prosocial behaviour has important real-world applications:
🏥 Emergency Services
Training programmes teach people to overcome the bystander effect and take action in emergencies. Clear instructions like "You in the red shirt, call 999" can overcome diffusion of responsibility.
💰 Charity Campaigns
Charities use psychological principles to increase donations, such as showing identifiable victims to increase empathy or emphasising social norms by showing that others are donating.
🎓 Education
Schools implement programmes to increase prosocial behaviour through modelling, reinforcement and empathy training to reduce bullying and increase cooperation.
Exam Practice Question
Question: "Explain two factors that might influence whether someone helps in an emergency situation." [4 marks]
Sample Answer: One factor is the number of bystanders present. Research by Latané and Darley showed that as the number of bystanders increases, the likelihood of any individual helping decreases, due to diffusion of responsibility. Another factor is the clarity of the emergency. When a situation is ambiguous, people may experience pluralistic ignorance, looking to others to determine if help is needed. If no one else is reacting with concern, individuals are less likely to interpret the situation as requiring intervention.
Summary of Key Points
- Prosocial behaviour includes helping, sharing and cooperating with others

- Psychological explanations include the empathy-altruism hypothesis and negative state relief model
- Social explanations consider social norms, learning and situational factors
- The bystander effect explains why people sometimes fail to help in emergencies
- Latané and Darley's five-step model outlines the decision process for helping
- Key factors affecting helping include diffusion of responsibility, pluralistic ignorance and audience inhibition
