Key Studies of Culture and Behaviour

students, imagine moving from one country to another and suddenly noticing that people stand farther apart in line, greet each other differently, or expect students to speak up in class more often. 🌍 These differences are not random. They reflect how culture shapes behaviour, thinking, and social expectations. In IB Psychology SL, the sociocultural approach explains behaviour by looking at the influence of other people, groups, and cultural norms. This lesson focuses on key studies of culture and behaviour, showing how psychologists investigate whether behaviour is universal or shaped by culture.

Learning goals

By the end of this lesson, students, you should be able to:

• Explain the main ideas and terminology behind key studies of culture and behaviour.
• Apply IB Psychology reasoning to cultural research.
• Connect these studies to the sociocultural approach.
• Summarize how culture affects behaviour through evidence.
• Use examples from real studies in exam answers. ✍️

What do psychologists mean by culture?

Culture is the shared beliefs, values, customs, and practices of a group of people. It can influence how people think, feel, communicate, and behave. A key idea in this topic is that behaviour is not only based on biology or personality; it is also shaped by social learning and cultural expectations.

In IB Psychology, you will often see two important terms:

• Individualist cultures: value independence, personal achievement, and individual goals.
• Collectivist cultures: value group harmony, family ties, and shared responsibility.

These terms matter because researchers often compare cultures to see whether people from different societies behave differently in similar situations. For example, a student from an individualist culture may be encouraged to give personal opinions in class, while a student from a collectivist culture may be encouraged to avoid conflict and respect group consensus.

Why do psychologists study culture?

Psychologists study culture to answer questions such as:

• Are certain behaviours universal across all human societies?
• Are some behaviours learned through cultural norms?
• How does culture affect social perception, memory, or decision-making?
• How do people adapt when moving between cultures?

This fits the sociocultural approach because it focuses on how the social environment affects behaviour. It also connects to identity, stereotyping, enculturation, acculturation, and globalization.

One important exam idea is that culture can affect both what people do and how psychologists interpret what people do. That means researchers must be careful when generalizing findings from one group to all humans.

Key study 1: Berry’s research on conformity

One important study often used in this area is Berry’s cross-cultural research on conformity. Berry compared different societies, including hunter-gatherer, farming, and industrial groups, to see whether conformity levels changed with the type of social organization.

The basic idea was that cultures with more interdependence and stronger group cooperation would encourage more conformity, while cultures with more individual independence would encourage less conformity. Berry found that conformity varied across cultures, suggesting that social structure influences behaviour.

This study is important because it shows that a behaviour often seen as “personal” may actually be shaped by cultural expectations. If a society depends on cooperation for survival, then conforming to group norms may be more adaptive. If people live in more individualistic settings, independent decision-making may be more valued.

Why this study matters

Berry’s work supports the idea that behaviour is culturally learned. It also shows how the same psychological process can look different in different societies. For example, in a school group project, students in one culture may quickly agree with the group leader, while students in another culture may openly debate ideas. Neither pattern is “better”; they reflect different cultural values.

Exam tip

When using Berry in an answer, students, explain the aim, the cross-cultural comparison, and the conclusion that conformity is influenced by cultural context. Then link it to the sociocultural approach by stating that behaviour is shaped by social norms and group life.

Key study 2: Cole and Scribner on memory

Another major study is Cole and Scribner’s research on memory among people from different cultural backgrounds. They investigated how cultural practices, especially schooling, affect memory performance.

Their findings suggested that memory is not just a fixed mental ability. Instead, memory strategies can depend on what people learn in their environment. People who had experience with formal schooling were more likely to use memorization strategies that improved recall in laboratory tasks.

This is a powerful example of enculturation, which means learning the norms, values, and skills of one’s own culture. If a culture teaches children to practice certain ways of remembering, then those methods become part of everyday thinking.

Why this study matters

This study shows that test performance may reflect cultural experience rather than pure intelligence. For example, a student who has practiced memorizing lists for school may do well on a memory task, while someone whose culture emphasizes storytelling or practical problem-solving may use different strategies that are just as useful in daily life.

This is important for IB Psychology because it reminds us not to treat psychological tests as culturally neutral. A task designed in one country may not measure the same thing in another country.

Key study 3: Cole and Scribner on categorization and reasoning

Cole and Scribner also studied how people categorize objects and solve problems in different cultural settings. Their research showed that cognitive tasks are influenced by how people are taught to think in their own communities.

For example, some cultures emphasize grouping objects by practical relationships, while others emphasize abstract categories. This means that cognitive style is partly shaped by education and daily social experience.

The lesson here is that reasoning is not identical everywhere. A person’s way of solving a problem may be closely connected to the activities valued in their culture. A student used to helping family businesses may think in practical, context-based ways, while a student trained in formal classroom reasoning may focus on abstract rules.

Key study 4: Matsumoto and cultural display rules

A highly relevant area in culture and behaviour is emotional expression. Matsumoto researched how display rules influence the way people show emotions across cultures.

Display rules are cultural rules about when, where, and how emotions should be shown. For example, some cultures encourage open emotional expression, while others expect people to hide emotions in public to preserve harmony or respect.

Matsumoto found cultural differences in emotional expression and recognition. This suggests that although humans may experience similar basic emotions, cultures shape how emotions are displayed and understood.

Real-world example

students, think of a student who receives a disappointing test grade. In one culture, they may openly show frustration and seek support. In another, they may hide disappointment to avoid embarrassing themselves or their family. The feeling may be similar, but the expression is culturally guided.

This is a good example of how behaviour is influenced by social norms. It also helps explain why people can misunderstand each other across cultures. A quiet face may be seen as calm in one culture and cold in another.

Enculturation and acculturation in cultural studies

Two essential terms in this topic are enculturation and acculturation.

• Enculturation is the process of learning one’s own culture.
• Acculturation is the process of adapting to a new culture after contact with it.

Key studies of culture and behaviour often help psychologists understand both processes. For example, when a child learns how to greet adults, speak in class, or show respect, that is enculturation. When a family migrates to a new country and learns new social rules, that is acculturation.

Acculturation can affect behaviour, identity, and even mental health. A student may feel caught between the values of their home culture and the new culture at school. This can influence confidence, social relationships, and choices.

How to use these studies in IB Psychology answers

When answering exam questions, students, do not just name the study. You should explain the psychological idea and link it to the question.

A strong answer often includes:

1. A clear definition of the cultural concept.
2. A named study.
3. The key finding.
4. A link to behaviour and the sociocultural approach.
5. A real-world or exam-specific example.

For example, if asked whether culture affects memory, you could write that Cole and Scribner found memory strategies differ across cultural contexts, showing that cognitive processes are shaped by social learning and education.

If asked about conformity, you could use Berry to show that social structure and group interdependence influence how much individuals follow group norms.

Strengths and limitations of cultural studies

Cultural studies are valuable because they reveal that behaviour is not universal in every detail. They help psychologists avoid assuming that one culture represents all humans.

However, there are also limitations:

• Cross-cultural comparisons can be hard because cultures are complex and not easy to define.
• People within the same culture are not all identical.
• Some studies may use tasks that favour one cultural group over another.
• Researchers must be careful about ethnocentrism, which is judging other cultures using one’s own cultural standards.

These limitations do not make the studies useless. Instead, they show why careful design and interpretation are important. Good psychology asks not only “What did the study find?” but also “In what context did it find it?”

Conclusion

Key studies of culture and behaviour show that human behaviour is deeply influenced by the social world. Research on conformity, memory, reasoning, and emotional expression demonstrates that culture shapes what people learn, how they solve problems, and how they interact with others. These studies are central to the sociocultural approach because they reveal that behaviour cannot be fully understood without considering the cultural context. For IB Psychology SL, students, the main message is clear: culture does not just surround behaviour; it helps create it. 🌎
