Key Studies of Culture and Prosocial Behaviour
Welcome, students 🌍🤝! In this lesson, you will explore how culture can shape prosocial behaviour, which means actions that help other people or benefit society. By the end of this lesson, you should be able to explain key ideas, use important terminology, and connect research findings to the broader IB Psychology topic of Human Relationships.
Introduction: Why do people help? 😊
Prosocial behaviour includes helping, sharing, comforting, cooperating, and donating. These actions can happen in everyday life, such as helping a classmate understand homework, donating food to a shelter, or standing up for someone who is being excluded. Psychologists study prosocial behaviour because it reveals how people build relationships, support groups, and maintain social harmony.
Culture matters because it influences what people see as “normal” or “good” behaviour. In some cultures, helping may be strongly linked to family loyalty and group responsibility. In others, it may be more connected to individual choice and personal values. That means the same action can have different meanings depending on the cultural context.
Learning objectives
By the end of this lesson, students, you should be able to:
- explain the main ideas and terminology behind key studies of culture and prosocial behaviour,
- apply IB Psychology SL reasoning to these studies,
- connect the studies to Psychology of Human Relationships,
- summarize why they matter in the topic area,
- use evidence and examples in exam-style responses.
Understanding prosocial behaviour and culture
Prosocial behaviour is any voluntary action intended to benefit another person or group. Important examples include helping, sharing, cooperating, donating, and comforting. Researchers often compare prosocial behaviour across cultures to see whether people help in similar ways everywhere or whether social norms influence helping.
Culture is a shared system of values, beliefs, customs, and rules that guides how people think and behave. A key distinction in psychology is between individualist cultures and collectivist cultures. Individualist cultures tend to emphasize independence, personal goals, and individual achievement. Collectivist cultures tend to emphasize group goals, family duty, and social harmony. These differences can affect when, why, and how people help others.
One important idea is social responsibility, which is the belief that people should help those in need. Another is norms, which are informal rules about how to behave. For example, in a community where cooperation is strongly valued, helping may happen more often because people learn that supporting others is expected.
Key Study 1: Levine et al. and helping across cultures
One major study in this topic is by Levine and colleagues, who investigated helping behaviour across different cities around the world. Their goal was to compare how likely people were to help strangers in various real-world situations. This study is often used because it provides a broad cross-cultural view of prosocial behaviour.
What they did
Researchers used a naturalistic method in several cities and created situations where help was needed, such as a person dropping papers, being visually impaired and needing assistance, or carrying an item that made movement difficult. Observers recorded whether bystanders helped.
What they found
Helping rates were not the same in every country or city. Some places showed higher rates of helping strangers than others. The results suggested that culture, urban environment, and social norms can influence helping behaviour. In some locations, people were more likely to assist strangers quickly, while in others they were less likely to do so.
Why this matters
This study is useful because it shows that prosocial behaviour is not only a matter of personality. The social environment matters too. It also demonstrates that helping can be studied in real-life situations rather than only in laboratories. That makes the findings more realistic and closely connected to everyday human relationships.

For IB, students, remember that this study supports the idea that cultural context affects behaviour. It also helps you discuss ecological validity, because the helping situations happened in everyday settings rather than artificial tasks.
Key Study 2: Whiting and Whiting and children’s prosocial development
Another important line of research comes from Whiting and Whiting, who studied children in different cultures to understand how socialization affects prosocial behaviour. They looked at how children were taught to behave and how culture shaped helping and sharing.
What they did
They observed children in several societies and compared their behaviour in natural settings. They paid attention to how children were raised, what tasks they were expected to do, and how much responsibility they had for helping at home or in the community.
What they found
Children in cultures that expected cooperation and family contribution often showed more helpful behaviour. In these settings, children learned early that helping is part of daily life. In cultures where children were given more independence and fewer family responsibilities, helping behaviour appeared differently.
Why this matters
This study suggests that prosocial behaviour is learned through socialization. Children do not simply “become helpful” by accident. They learn through observation, practice, rewards, and expectations from adults and peers. This helps explain why culture can shape relationship behaviour from a young age.
IB Psychology link
This study connects to the broader topic of human relationships because early family interactions affect later social behaviour. It also shows the role of social learning and cultural norms in shaping relationships with others.
Key Study 3: Cross-cultural comparisons of fairness and sharing
Research on fairness and sharing also helps explain prosocial behaviour. In many studies, psychologists test whether people in different cultures divide resources equally or in ways that reflect local norms. These studies often use games or sharing tasks to examine how people make decisions about helping and fairness.
What these studies suggest
In some cultures, equal sharing is strongly valued. In others, sharing may depend on family status, age, obligation, or group membership. People may be more willing to help members of their own group than strangers. This is important because prosocial behaviour is not always universal in the same form.
Example in real life
A student may share lunch with a friend because friendship creates a sense of obligation. Another student may donate money to a charity because their school encourages social responsibility. In both cases, the helping behaviour is shaped by social expectations and relationships.
Why this matters
These studies show that prosocial behaviour can be influenced by in-group loyalty, fairness norms, and cultural values. They also remind us that helping is not always purely spontaneous; sometimes it follows deeply learned social rules.
How to use these studies in IB Psychology answers ✍️
When writing an IB Psychology response, students, you should do more than just describe the studies. You need to explain what the findings mean and how they connect to the question.
A strong answer usually includes:
- a clear definition of prosocial behaviour,
- a description of culture as a factor in behaviour,
- at least one named study,
- evidence from the study,
- a link to the question asked.
For example, if asked whether culture affects prosocial behaviour, you could explain that Levine et al. found different helping rates across cities, suggesting that helping is influenced by cultural and social contexts. You could then add that Whiting and Whiting showed how children learn helping through socialization, which supports the idea that prosocial behaviour develops within cultural settings.
Evaluation: strengths and limitations of the research
IB Psychology expects evaluation, so it is important to think critically about these studies.
Strengths
- Many of these studies use real-life behaviour, which increases ecological validity.
- Cross-cultural research provides a wider view of human behaviour than studies from one country alone.
- The findings are useful for understanding everyday relationships, community life, and social responsibility.
Limitations
- Cultural categories can be too broad. Not every person in a culture behaves the same way.
- Helping behaviour may be affected by many variables, such as city size, public safety, time pressure, and economic conditions.
- Some studies observe behaviour without fully knowing the participants’ reasons for helping.
- Cross-cultural comparisons can risk oversimplifying differences between societies.
These limitations do not make the studies useless. Instead, they show that psychology must be careful when making generalizations about culture and prosocial behaviour.
Connection to Psychology of Human Relationships
This lesson fits into Psychology of Human Relationships because prosocial behaviour is one of the ways people maintain positive relationships. Helping, sharing, and cooperating support trust and social bonding. Cultural norms influence whether people are expected to help family, friends, strangers, or community members.
Prosocial behaviour is also important in group dynamics and conflict. When people cooperate, relationships often improve and conflict may decrease. When people only help their own group, relationships with outsiders may become weaker. Understanding culture helps explain why some groups are more cooperative, why some communities show strong social responsibility, and why helping can differ across settings.
In real life, this matters in schools, workplaces, and communities. A school with a strong culture of inclusion may encourage students to help one another more often. A workplace that values teamwork may create more cooperation. A community facing hardship may rely heavily on mutual support. These are all examples of prosocial behaviour in human relationships.
Conclusion
Key studies of culture and prosocial behaviour show that helping is shaped by both human nature and social environment. Research by Levine and others shows that helping rates vary across cultures. Studies by Whiting and Whiting suggest that children learn prosocial behaviour through socialization. Together, these findings show that culture influences when, how, and why people help others.
For IB Psychology SL, students, the main takeaway is that prosocial behaviour cannot be understood only as an individual trait. It is also a social and cultural behaviour that reflects values, norms, and relationships. This makes it a powerful part of the Psychology of Human Relationships 🌎🤝.
