Introduction to the Use of Children in Research

Welcome to one of the most important "issues and debates" in your AS Psychology course! In this chapter, we explore why psychologists study children and, more importantly, the special rules they must follow to do it correctly. Since children are still developing, they see the world differently than adults do. This makes them fascinating to study, but it also means we have a huge responsibility to keep them safe and respected.

Why do we study children? We study them to understand how we grow, how we learn (like in the Bandura et al. study), and how to help them with fears (like in the Saavedra and Silverman study). Don't worry if this seems like a lot to remember—we will break down the ethics and the practicalities step-by-step!

The Ethical Rules: Protecting Young Participants

When researchers work with children, they must follow the same ethical guidelines as they do with adults, but with much higher standards because children are considered vulnerable. Here are the key ethical points you need to know for your exam:

1. Consent and Assent

In most countries, children under the age of \(16\) cannot give legal informed consent. This means researchers must ask the parents or guardians for permission. However, psychologists also try to get assent—this is the child’s own agreement to take part, explained in a way they can understand.

2. Protection from Harm

This is the most important rule. Researchers must ensure that the child is not stressed, frightened, or hurt during the study. Because children are more easily upset than adults, what might be a "minor" stress for an adult could be very scary for a child. Example: In the Bandura et al. study, children saw an adult being aggressive. Some psychologists argue this might have caused long-term "psychological harm" by teaching them that violence is okay.

3. The Right to Withdraw

Everyone in a study has the right to stop and leave at any time. However, children might feel pressured because the researcher is an adult and an "authority figure." Researchers must look for signs that a child is unhappy (like crying or turning away) and stop the study immediately, even if the child doesn't say "I want to leave."

4. Confidentiality and Privacy

A child's identity must be kept secret. In the Saavedra and Silverman study, the researchers referred to the participant simply as a "9-year-old boy" to protect his privacy while describing his treatment for a button phobia.

Quick Review: Think of the word SAFE.
S – Secret (Confidentiality).
A – Agreement (Consent from parents).
F – Feeling okay (Protection from harm).
E – Exit (Right to withdraw).

Methodological Issues: The Challenges of Studying Kids

It’s not just about ethics; it’s also about how we actually do the research. Using children creates specific "methodological" (how the study is done) challenges.

Language and Understanding

Children have a smaller vocabulary than adults. If a researcher uses "big words," the child might get confused and give an answer that doesn't make sense. This lowers the validity of the research (meaning the study isn't measuring what it's supposed to).

Demand Characteristics

Children are often taught to be helpful to adults. In a research study, they might try to guess what the "teacher" or "scientist" wants them to do and then do it just to be "good." This is a demand characteristic, and it can spoil the results because the child isn't acting naturally.

Short Attention Spans

Younger children get bored or tired much faster than adults. If a task is too long, they might stop trying, which affects the reliability of the data.

Did you know? In the Pozzulo et al. study on line-ups, researchers had to be very careful about how they asked children to identify suspects to make sure the kids didn't just pick someone because they felt they had to choose.

Core Studies Linked to This Issue

To do well in your Paper 1 exam, you must be able to link this debate to the 12 core studies. Here are the three most relevant ones for this chapter:

  • Bandura et al. (aggression): Used children aged \(3\) to \(6\) years. This study is often criticized because it deliberately exposed children to aggression, which could be seen as failing to protect them from harm.

  • Saavedra and Silverman (button phobia): This was a case study of one 9-year-old boy. It shows how research can be helpful to children by using therapy (like evaluative learning) to cure a phobia.

  • Pozzulo et al. (line-ups): This study compared children and adults to see who was better at identifying faces. It found that children were more likely to make a false positive (identify someone even if the "criminal" wasn't there) because they felt social pressure to pick someone.

Strengths and Weaknesses of Using Children

Strengths:
  • Understanding Development: It is the only way to find out how children's minds change as they grow.
  • Improving Lives: Research can help us create better teaching methods or treatments for childhood phobias and disorders.
  • Honesty: Younger children are often less likely to "filter" their behavior than adults, which can sometimes lead to more honest data.
Weaknesses:
  • Ethics: It is much harder to ensure a child is truly protected and understands their rights.
  • Communication: It can be difficult to know if a child truly understands the questions they are being asked.
  • Interpretations: Since adults are doing the observing, they might misinterpret a child’s play or behavior through an "adult lens."

Common Mistake to Avoid: Don't just say "it's unethical to use children." It is perfectly ethical as long as the specific guidelines (like parental consent and protection from harm) are followed. Always use the word vulnerable to describe why we need extra rules.

Key Takeaway Summary

The "Use of Children" issue is a balance between gaining valuable knowledge about human development and protecting a vulnerable group. Researchers must get parental consent, ensure the child is safe, and use methods that the child can understand. Core studies like Bandura, Saavedra, and Pozzulo show us both the benefits and the ethical "traps" of this type of research.
