Key Studies of Culture and Behaviour

Welcome, students 👋 This lesson explores how psychologists study the relationship between culture and behaviour in the Sociocultural Approach. By the end, you should be able to explain the key ideas, describe important studies, and use evidence to answer IB Psychology HL questions. The big question is simple but powerful: how much of what we think, feel, and do is shaped by the culture around us?

What the Sociocultural Approach Tries to Explain

The sociocultural approach says that behaviour is influenced by the social groups and cultural environment people grow up in. Culture includes shared beliefs, values, customs, language, and ways of living. Social context matters too, because people change their behaviour depending on who they are with and what their society expects.

A key idea in this topic is that behaviour is not only the result of biology or individual choice. Instead, it is shaped by social learning, social norms, roles, and cultural expectations. For example, in some cultures, children are encouraged to speak openly and challenge adults, while in others they are taught to be quiet and respectful. Both behaviours may be seen as appropriate depending on the cultural setting.

In IB Psychology HL, you must be able to explain terms such as culture, enculturation, acculturation, social norms, stereotyping, and conformity. You also need to understand that psychologists often compare cultures to see whether a behaviour is universal or culture-specific.

Why do researchers compare cultures?

Comparing cultures helps psychologists identify whether behaviour is shaped mainly by shared human processes or by cultural experience. If a behaviour appears in many very different cultures, it may be a more universal pattern. If it changes a lot from one culture to another, culture is likely playing a major role.

However, culture is not easy to study. Researchers must be careful about bias, especially ethnocentrism, which is judging another culture using the standards of one’s own culture. Good research tries to avoid this by using clear methods and comparing groups fairly.

Key Studies on Culture and Behaviour

Several studies are especially important because they show how culture influences memory, thinking, obedience, and social behaviour. These studies help psychologists understand whether behaviour is shaped by individualism or collectivism, and how cultural values affect everyday actions.

Bartlett and the role of culture in memory

One early and famous study is by Frederic Bartlett. He used a story called “War of the Ghosts” and asked British participants to remember it over time. He found that people did not recall the story exactly. Instead, they changed details so the story fit their own expectations and cultural background.

Bartlett showed that memory is not like a camera taking a perfect picture. It is reconstructive, meaning people rebuild memories using what they already know. This is important for culture because people often use schemas, which are mental frameworks based on experience. If a story or event does not match someone’s cultural schema, they may simplify or alter it.

For example, if a student in one country hears a story about a traditional ritual from another culture, they may misunderstand details that are obvious to someone from that culture. Bartlett’s study suggests that culture affects what we notice, remember, and explain.

Berry and cross-cultural differences in conformity

John Berry compared conformity in different cultures and found that people in collectivist cultures often show higher conformity than those in individualist cultures. Collectivist cultures emphasize group harmony, cooperation, and belonging. Individualist cultures emphasize independence, personal choice, and self-expression.

Berry’s work helped show that conformity is not the same everywhere. In a collectivist society, agreeing with the group may be seen as respectful and socially responsible. In an individualist society, standing out and expressing an original opinion may be valued more.

This is useful in IB because it shows how social norms vary across cultures. If students is asked to explain conformity, you can mention that culture influences whether conformity is encouraged or discouraged.

Zhang and the Holtz study on thinking styles

Some studies show that culture influences how people think about the world. Research by Zhu and colleagues, and similar work by Nisbett and others, has found differences between holistic and analytic thinking. Holistic thinking focuses on relationships, context, and the whole picture. Analytic thinking focuses on individual objects and categories.

In many East Asian cultures, people tend to be more holistic in their thinking, while in many Western cultures, people tend to be more analytic. This does not mean everyone in a culture thinks the same way, but it does suggest broad cultural patterns.

For example, if a person sees a fish swimming in front of rocks, a holistic thinker may remember the background and relationship between the fish and the environment. An analytic thinker may focus mainly on the fish itself. These differences show that culture can shape perception and cognition.

Milgram, obedience, and cultural variation

Although Stanley Milgram’s obedience study is often discussed under social influence, it also connects to culture. Later cross-cultural research suggested that obedience levels can differ across countries. This means authority is not understood in exactly the same way everywhere.

In some cultures, authority figures such as teachers, parents, or government leaders are given strong respect. In others, people are more likely to question authority. This matters because cultural values can influence whether someone obeys commands even when they feel uncomfortable.

When using Milgram in an essay, students should remember that the original study was done in one cultural context, so psychologists must be careful about applying its findings to all societies without checking for cultural differences.

How These Studies Fit the Bigger Sociocultural Picture

The key studies of culture and behaviour connect directly to the main ideas of the sociocultural approach. They show that behaviour is influenced by the group and environment people live in, not just by individual personality.

Enculturation and acculturation

Enculturation is the process of learning the norms, values, and behaviours of one’s own culture from a young age. Children learn this from parents, teachers, peers, media, and community practices. Acculturation is the process of adapting to a new culture after moving to a different country or environment.

The studies above help explain both processes. For example, Bartlett’s work suggests that as people learn cultural schemas, they remember and interpret events through that cultural lens. Berry’s findings suggest that people may adapt differently depending on whether they are moving into a collectivist or individualist society.

A real-world example is a student who moves from a country where group decisions are common to one where individual opinions are encouraged. At first, the student may feel unsure about speaking up in class. Over time, they may acculturate and adjust their behaviour to fit the new setting.

Culture and social influence

Culture affects social influence because people learn what is acceptable by watching others. Norms guide behaviour, and groups reward people who follow them. This can shape conformity, obedience, and even memory.

For example, a teenager in a culture that values family duty may feel strong pressure to choose a career that supports the family. In another culture, the same teenager may be encouraged to choose independently based on personal interests. The sociocultural approach helps explain why these choices differ.

Globalisation and changing behaviour

Globalisation is the spread of ideas, products, and values across the world. It can reduce differences between cultures, but it can also create tension when global influences conflict with local traditions.

For example, social media may spread individualist values such as self-promotion and personal branding. At the same time, many communities continue to value collectivist traditions. Psychologists study these changes to understand how culture and behaviour evolve over time.

How to Use These Studies in IB Answers

When writing an exam response, students should do more than name a study. You need to explain the finding, link it to culture, and show why it matters.

A strong paragraph structure is: define the concept, describe the study, explain the result, and connect it to the question. For example:

Bartlett showed that memory is reconstructive because participants changed details of a story to fit their cultural expectations. This suggests that culture shapes cognition through schemas. Therefore, what people remember is not only influenced by the event itself but also by the cultural framework they use to interpret it.

Another useful technique is to compare cultures carefully. Do not say one culture is better or worse. Instead, explain that different cultural values lead to different behaviours. That keeps your answer scientific and balanced.

Common exam-ready terms

• $\text{Culture}$: shared beliefs, values, customs, and practices in a group
• $\text{Enculturation}$: learning one’s own culture
• $\text{Acculturation}$: adapting to a new culture
• $\text{Collectivism}$: emphasis on group goals and harmony
• $\text{Individualism}$: emphasis on personal goals and independence
• $\text{Schema}$: a mental framework that helps organize information
• $\text{Ethnocentrism}$: judging another culture by your own standards

Conclusion

The key studies of culture and behaviour show that psychology cannot fully understand people without considering their social and cultural context. Bartlett demonstrated that memory is shaped by cultural schemas. Berry and later researchers showed that conformity and thinking styles differ across cultures. Together, these studies support the sociocultural view that behaviour is learned, guided, and interpreted through culture.

For IB Psychology HL, students should remember that the goal is not just to memorize facts. The goal is to explain how culture influences behaviour, use studies as evidence, and connect them to broader themes such as identity, social cognition, stereotyping, enculturation, acculturation, and globalisation. 🌍
