Introduction: Does TV Change How We Behave?

Have you ever watched an action movie and felt like you could take on the world? Or maybe you’ve heard adults worry that playing violent video games or watching "nasty" TV shows makes children more aggressive. This is a huge debate in Criminal Psychology.

While Bandura (1961) showed that children might imitate what they see in a lab, Charlton et al. (2000) wanted to see what happens in the real world. They had a unique opportunity to study a remote island that was getting television for the very first time. Let’s dive into what they found!

The Study: Charlton et al. (2000)

This study is known as a natural experiment. This means the researchers didn't manipulate the environment themselves; they just took advantage of a naturally occurring change—the arrival of TV on a remote island.

The Aim

The researchers wanted to investigate whether the introduction of broadcast television to a remote community would lead to an increase in aggressive and antisocial behaviour in children.

The Procedure

The study took place on St Helena, a tiny, isolated island in the South Atlantic Ocean. Before \(1995\), the island had no TV broadcasts.

1. The Timeline: The researchers began observing the children in \(1994\) (before TV arrived) and continued for five years after TV was introduced.
2. The Participants: They focused on children aged \(3\) to \(8\) years old from two primary schools on the island.
3. Data Collection: The researchers used naturalistic observation. They set up video cameras in the school playgrounds to record the children’s behaviour during break times.
4. Coding Behaviour: To make the study objective (fair and factual), they used a coding system to count specific behaviours: Pro-social behaviours: Things like sharing, playing together, or showing affection. Anti-social behaviours: Things like kicking, pushing, or fighting.

The Findings: Results and Conclusions

The Results

You might be surprised by what the researchers found! After analyzing hundreds of hours of footage, they discovered: No significant increase in aggressive or antisocial behaviour. The children on St Helena remained generally well-behaved and maintained high levels of pro-social behaviour. In fact, anti-social behaviour was very rare both before and after the TV arrived.

The Conclusions

Charlton et al. concluded that television does not automatically cause aggression. Even though the children were exposed to the same violent content as children in the UK, they didn't imitate it.

The researchers suggested that the community played a big role. St Helena was a very close-knit island where everyone knew each other, and adults supervised children closely. This social control prevented the children from acting out, even if they saw it on the screen. This links to Social Learning Theory, suggesting that we don't just "copy" everything—our environment and consequences matter too!

Quick Review: Think of it like this—seeing a character jump off a building on TV doesn't mean you'll do it, especially if your parents and teachers are right there telling you it’s dangerous!

Evaluating the Study

To do well in your exam, you need to be able to look at the strengths (the good bits) and weaknesses (the flaws) of this research.

Strengths

+ High Ecological Validity: Because it was a natural experiment in a real playground, the children behaved naturally. They weren't in a fake lab environment like Bandura’s study.
+ Longitudinal Study: By following the children over five years, the researchers could see the long-term effects of TV, not just a "one-off" reaction.
+ Use of Video: Using cameras allowed multiple researchers to watch the footage and agree on the scores. This makes the findings more objective and reliable.

Weaknesses

- Low Generalisability: St Helena is a very unique and remote place. Because the community was so close-knit, the results might not apply to big, anonymous cities like London or New York where social control is different.
- Selection Bias: Some people argue that the programs shown on St Helena might have been less violent than those in other countries, or that the "culture of the island" was simply too strong for the TV to influence.
- Researcher Bias: Although they used a coding system, the researchers might have subconsciously looked for certain behaviours that supported their ideas.

Common Mistakes to Avoid

Don't confuse this with Bandura (1961)! Bandura found that children did imitate aggression in a lab. Charlton found they did not in a real-life setting. Make sure you know which is which!
Don't say the kids became "better" behaved. The results simply showed that their behaviour didn't change significantly for the worse.

Key Takeaway for Exam Success

When answering a question on Charlton et al. (2000), always mention that it was a natural experiment on St Helena and that it contradicted the idea that TV always causes violence. Remember to use the terms pro-social and anti-social behaviour to score those top marks!
