Key Studies of Globalisation and Behaviour

Welcome, students 🌍. In this lesson, you will learn how psychologists study the effects of globalisation on behaviour. Globalisation means the increasing connection of people, cultures, businesses, and media across the world. It can change how people think, what they value, how they act, and even how they see themselves. In IB Psychology, this topic belongs to the sociocultural approach because it looks at how social groups and cultural forces shape behaviour.

What you will learn

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

• explain the main ideas and key terms connected to globalisation and behaviour,
• describe important research studies in this area,
• use psychological evidence to support arguments about globalisation,
• connect these studies to enculturation, acculturation, identity, and social influence.

Globalisation affects everyday life in visible ways. A teenager in one country may wear the same brand of shoes, listen to the same music, and use the same social media apps as a teenager on the other side of the world. But the key question for psychologists is not just what spreads. It is how global forces change behaviour, identity, and relationships. 📱

Globalisation: the big idea

Globalisation is the process by which people, products, ideas, and media move across national borders more easily than before. It is driven by travel, trade, migration, and digital communication. Psychologists are interested in how this process influences behaviour because behaviour does not happen in a vacuum. People respond to what they see around them, and globalisation changes that environment.

One important idea is cultural convergence, which means cultures may become more similar over time. For example, many cities around the world now have fast-food chains, streaming services, and similar fashion trends. However, globalisation does not simply erase cultural differences. Sometimes people adapt global influences to local traditions, creating hybridity or “glocalisation,” where global and local elements mix together.

Another important concept is social influence. People often change behaviour to fit in with peers, family, or society. Global media can expand the range of people who influence us. A student may now compare themself not only with classmates but also with influencers, celebrities, and online communities from many countries.

Key study 1: Arnett and youth identity in a global world

One major psychologist linked to this topic is Jeffrey Arnett, who studied how globalisation affects adolescents and emerging adults. He argued that young people are especially influenced by global culture because they are still developing identity and values.

Arnett suggested that globalisation gives young people access to new ideas, lifestyles, and identities. This can be exciting because it increases choice. For example, students, a teenager might learn about music styles, social causes, or career paths that would have been less visible in the past. At the same time, more choice can create stress because it can be harder to decide who to be.

Arnett also described how global media can shape a shared youth culture. Teenagers in different parts of the world may enjoy the same songs, fashion, or slang. This does not mean all young people become identical, but it does show that global forces can influence identity development.

Why this matters in psychology

Arnett’s work is useful because it links globalisation to identity formation, a major topic in the sociocultural approach. Identity is shaped by both personal choices and social surroundings. Globalisation increases the number of cultural messages people receive, so it can widen identity options while also increasing pressure to compare oneself to others.

For IB exam answers, you can explain that globalisation may lead to both opportunity and challenge. It may help adolescents explore identities, but it can also increase confusion, consumer pressure, or feelings of not belonging. 🌐

Key study 2: Berry and acculturation in a global context

Another important name is John Berry, whose work on acculturation is central to sociocultural psychology. Acculturation refers to the process of cultural and psychological change that happens when people from different cultures come into contact. Globalisation increases these contacts through migration, tourism, international education, and online communication.

Berry identified four acculturation strategies:

• Integration: keeping aspects of the original culture while also participating in the new culture,
• Assimilation: giving up the original culture and adopting the new one,
• Separation: maintaining the original culture and avoiding the new one,
• Marginalisation: losing connection with both cultures.

These strategies help explain how people respond to globalisation. For example, a family moving to a new country may keep traditional foods and language at home while also joining school events and local customs. That would be integration.

Real-world example

Imagine students moves to another country because of a parent’s job. At school, students may adapt to new social norms, clothing styles, or language use. At home, students may still celebrate festivals from the family’s original culture. This shows that globalisation does not produce one simple reaction. Instead, it creates many possible responses depending on identity, support, and context.

Berry’s theory is valuable because it explains that adaptation is not just about “fitting in.” It also involves psychological well-being, belonging, and cultural continuity. In many studies, integration is linked to more positive outcomes than marginalisation because it allows people to keep important parts of identity while building new connections.

Key study 3: Cultural change through media and consumer behaviour

A third important line of evidence in this topic comes from studies of media influence and consumer behaviour. Globalisation spreads advertising, celebrities, and brand images across countries. Psychologists examine how this changes attitudes and behaviour, especially among young people.

Research in sociocultural psychology shows that repeated exposure to media images can shape beliefs about success, attractiveness, gender roles, and lifestyle. For example, global advertising often links happiness with buying products. This can influence consumer behaviour by making people more likely to want the same items as those shown in media.

This is a strong example of normative social influence. People may copy behaviours because they want acceptance or fear rejection. If a certain brand, hairstyle, or online trend becomes popular globally, teenagers may follow it to feel included. Social media intensifies this because trends can spread very quickly.

What psychologists conclude

The key psychological point is that globalisation changes the social environment. Behaviour changes when the environment changes. If people are repeatedly exposed to similar images and norms, they may start to think that these are normal or desirable. This can affect spending, self-esteem, and identity.

However, psychologists also note that people are not passive. They interpret media in different ways depending on age, culture, and personal experience. Two people may see the same video and react very differently. This is why sociocultural explanations always consider both external influence and individual response. 📺

Linking the studies to the sociocultural approach

The sociocultural approach explains behaviour by focusing on the influence of social groups, culture, and interaction. The key studies of globalisation fit this approach because they show how large-scale cultural change affects the individual.

Here is the connection:

• Culture and behaviour: global culture changes the norms, values, and behaviours that people learn.
• Enculturation: children learn shared beliefs and behaviours from family, school, and media.
• Acculturation: migrants and minority groups adapt when exposed to another culture.
• Identity and social cognition: people form ideas about themselves partly through the messages they receive from society.
• Stereotyping: global media can spread simplified images of groups, which may reinforce stereotypes or challenge them.

For example, a global film may show one culture in a limited way. That can shape how viewers think about people from that culture. At the same time, international media can also introduce more diverse representations and reduce prejudice. The effect depends on the content and the audience.

How to use these studies in an IB answer

When answering IB Psychology questions, you need more than a definition. You need explanation, example, and analysis. A strong response should do three things:

1. define globalisation or the key concept,
2. describe a study or theory accurately,
3. explain how the evidence shows behaviour is shaped by sociocultural forces.

For example, if asked whether globalisation changes identity, you could say that Arnett’s research suggests global media gives adolescents more identity options, while Berry’s acculturation theory shows that people respond to global contact in different ways depending on their context. Then you could explain that social media and advertising can affect norms through social influence.

A top-quality answer also includes evaluation. You might mention that globalisation is not experienced equally by everyone. Access to technology, migration status, language, and local traditions all affect the outcome. This means globalisation is powerful, but not identical in every society.

Conclusion

Globalisation is a major force shaping behaviour in the modern world. It spreads ideas, products, and media across borders, influencing identity, consumer choices, values, and social norms. Key studies by Arnett, Berry, and research on media influence help psychologists understand how people respond to these changes. students, the main lesson is that behaviour is shaped not only by personal traits but also by cultural contact and global social forces. The sociocultural approach helps explain why people in different places may become more similar in some ways, while still keeping important cultural differences. 🌍
