Acculturation in the Sociocultural Approach to Understanding Behaviour

students, imagine moving to a new country, starting at a new school, or joining a community with different customs, foods, language, and rules 🌍. You may keep some of your original traditions while also learning how to fit into the new environment. That process is called acculturation. In IB Psychology HL, acculturation is important because it helps explain how culture shapes behaviour, identity, and social adjustment.

In this lesson, you will learn how to:

• explain the main ideas and terminology behind acculturation,
• apply acculturation to real-life situations and IB-style reasoning,
• connect acculturation to the broader Sociocultural Approach to Understanding Behaviour,
• and use evidence and examples to show how acculturation affects people.

Acculturation is not just about learning a new language or customs. It is about how people and groups change when they come into contact with another culture. This makes it a key idea in understanding identity, social cognition, stereotyping, and behaviour.

What is Acculturation?

Acculturation is the process of cultural and psychological change that happens when individuals or groups come into continuous contact with a different culture. This can happen through migration, studying abroad, adoption, marriage, work, or living in a multicultural society.

A key idea is that acculturation is not the same as simple copying. People do not automatically lose their original culture when they meet a new one. Instead, they may combine, adapt, or resist cultural influences. That means acculturation can affect language, values, food, clothing, beliefs, social behaviour, and even self-identity.

A useful concept in this topic is the acculturative stress that some people experience. This is the stress that can happen when someone struggles to adjust to a new culture. It may come from language barriers, discrimination, homesickness, or confusion about social rules. For example, students, a student who moves to a new country may understand the schoolwork but still feel anxious because the social expectations are unfamiliar.

Acculturation is especially important in psychology because it shows that behaviour is shaped by both the individual and the social environment. It helps psychologists understand how culture influences what people think is normal, respectful, polite, or successful.

Main Acculturation Strategies

Psychologist John Berry proposed a well-known model of acculturation. His model explains that when people enter a new culture, they usually face two main questions:

1. Is it important to maintain my original culture?
2. Is it important to interact with the new culture?

Based on the answers, Berry identified four acculturation strategies:

1. Integration

Integration happens when a person keeps important parts of their original culture while also taking part in the new culture. This is often seen as the healthiest and most balanced strategy when the host society is open and supportive.

Example: A teenager from India moves to Canada. They still celebrate Diwali with family, but they also join school clubs, make friends from different backgrounds, and adapt to Canadian school routines.

2. Assimilation

Assimilation happens when a person gives up much of their original culture and adopts the new culture.

Example: A student who moves to another country may stop using their home language and avoid cultural traditions in order to fit in with peers.

3. Separation

Separation happens when a person maintains their original culture and avoids the new culture.

Example: A family may live in an immigrant community, speak only their home language, and mainly socialize with people from the same culture.

4. Marginalization

Marginalization happens when a person feels disconnected from both the original culture and the new culture.

Example: A young person may not feel accepted by their family’s culture or by the host society. This can lead to isolation and identity confusion.

Berry’s model is useful because it gives psychologists a clear way to describe how people adapt. However, students, remember that real life is more complex than a simple four-box model. People may use different strategies in different situations, and their choices can change over time.

Acculturation and Identity

Acculturation matters because culture is closely tied to identity. Identity includes the beliefs, roles, values, and social groups that help people answer the question, “Who am I?” When someone enters a new culture, they may experience changes in their sense of self.

This can lead to bicultural identity, where a person identifies with two cultures and can move between them depending on the context. For example, a student may behave one way at home and another way at school, not because they are being fake, but because they are adapting to different social expectations.

Acculturation also links to social cognition. Social cognition is how people think about themselves and others in social situations. Newcomers may learn new rules about eye contact, personal space, greetings, or classroom participation. If they misunderstand these rules, others may judge them unfairly. This can create stereotypes and misunderstandings.

For instance, if a student from one culture speaks less in class, a teacher from another culture might wrongly assume the student is uninterested. In reality, the student may be showing respect by listening carefully. This shows how culture influences behaviour and interpretation.

Evidence and Research on Acculturation

One important area of research looks at how acculturation affects well-being. Studies often show that integration is linked with better psychological adjustment than strategies like marginalization. This is because people usually feel more supported when they can keep a meaningful connection to their heritage culture while also participating in the new culture.

Research on immigrant and minority groups has also found that acculturative stress can affect mental health. People may experience anxiety, low self-esteem, or loneliness if they face language difficulty, prejudice, or pressure to change. Children and adolescents may be especially affected because they are developing identity while also trying to fit in with peers.

In IB Psychology HL, it is important to use evidence carefully. You do not need to memorize every detail of a study, but you should be able to explain how research supports a theory or concept. For example, evidence that people in integrated cultures often report higher life satisfaction supports Berry’s idea that balancing both cultures can be beneficial.

A real-world example can help strengthen an exam answer. Imagine a refugee family arriving in a new country after leaving a conflict zone. The parents may want to preserve their language and traditions at home, while the children quickly learn the host country’s language from school. Different family members may acculturate at different speeds, which can create conflict but also flexibility. This is a strong example of how acculturation operates in everyday life.

Acculturation in the Sociocultural Approach

Acculturation fits neatly into the Sociocultural Approach to Understanding Behaviour because this approach argues that behaviour cannot be understood without considering social and cultural context. People are influenced by the groups they belong to, the norms they learn, and the wider society around them.

Acculturation connects to several key parts of the topic:

• Culture and behaviour: acculturation shows how behaviour changes when people move between cultures.
• Enculturation and acculturation: enculturation is learning your own culture, while acculturation is adapting to another culture.
• Identity, social cognition, and stereotyping: acculturation affects self-concept and how people are judged by others.
• Globalisation and social influence: migration, media, and international contact increase the chances that people will experience acculturation.

This means acculturation is not an isolated topic. It is a bridge between culture and behaviour. In many countries today, schools, workplaces, and communities are multicultural. Because of globalisation, more people are living in environments where they must navigate more than one cultural system. Psychologists study acculturation to understand both the challenges and strengths of this process.

For IB-style application, students, you should be able to explain how a person’s behaviour is shaped by social pressure, cultural expectations, and group membership. If a question asks why someone behaves differently after moving to a new country, acculturation may be a strong explanation.

Conclusion

Acculturation is the process of adapting to a new culture through contact with another group. It can involve maintaining the original culture, adopting the new one, or combining both. Berry’s four strategies — integration, assimilation, separation, and marginalization — provide a useful framework for describing this process.

Acculturation matters because it affects identity, stress, relationships, and behaviour. It also helps psychologists understand the role of culture in everyday life. Within the Sociocultural Approach, acculturation is essential for explaining how people think, feel, and act in different social environments. In other words, students, acculturation shows that behaviour is not only personal — it is also shaped by culture, context, and connection to others 😊.

Study Notes

• Acculturation is the psychological and cultural change that occurs when people come into continuous contact with a different culture.
• It can affect language, values, customs, identity, and social behaviour.
• Acculturative stress is the stress caused by difficulty adjusting to a new culture.
• Berry’s four acculturation strategies are:
• Integration: keep original culture and engage with the new culture.
• Assimilation: adopt the new culture and reduce attachment to the original culture.
• Separation: keep the original culture and avoid the new culture.
• Marginalization: feel disconnected from both cultures.
• Integration is often linked to better adjustment and well-being.
• Acculturation can shape identity and create bicultural identity.
• It connects to social cognition because people interpret behaviour through cultural expectations.
• It is part of the Sociocultural Approach because behaviour is influenced by social groups, norms, and culture.
• Use real-life examples, such as migrants, refugees, international students, or multicultural families, when applying the concept.
• In IB Psychology HL, always link acculturation to both individual experience and wider cultural context.
