Welcome to the Funhaler Study!
In this chapter, we are looking at a brilliant piece of contemporary research by Chaney et al. (2004). This study is part of the Developmental Area and focuses on the key theme: External influences on children's behaviour. While the classic study by Bandura showed how children learn through observation, Chaney explores how we can change children's behaviour using rewards and reinforcement.
The Big Idea: Why do we care?
Imagine you are a parent of a small child with asthma. You know they need their medicine to stay healthy, but the inhaler is boring, scary, or uncomfortable. Many children resist taking their medication, which is a big problem for doctors. Chaney wanted to see if Operant Conditioning—the idea that we repeat behaviours that have positive consequences—could help children use their inhalers correctly.
Background: Operant Conditioning
Before we dive into the study, you need to know one key term: Positive Reinforcement. This is when a behaviour is followed by a "reward," making it more likely that the behaviour will happen again. In this study, the "behaviour" is using the inhaler, and the "reward" is the fun toys attached to it.
Quick Note: This study is the "contemporary" pair to Bandura’s study on aggression. While Bandura looked at how children imitate what they see (Social Learning Theory), Chaney looks at how children’s behaviour is shaped by the consequences of their actions.
The Research Method
This was a field experiment. It didn't happen in a lab; it happened in the children's own homes. The researchers used a repeated measures design, which means every child was tested twice: once with their normal inhaler and once with the "Funhaler."
The Sample
The study included 32 children (22 male and 10 female). Their age range was \(1.5\) to \(6\) years old, with a mean age of \(3.2\) years. All the children had been diagnosed with asthma for some time.
The "Funhaler" Device
The Funhaler was a special inhaler designed to be attractive to children. It included:
• A spinning disk that only moved if the child breathed in deeply enough.
• A whistle that sounded when the child exhaled correctly.
These toys acted as incentives and provided immediate reinforcement for correct technique.
The Procedure: Step-by-Step
1. Parents were first interviewed using a structured questionnaire about their current inhaler (the standard one).
2. Parents were given the Funhaler to use with their child for two weeks at home.
3. During these two weeks, parents were contacted randomly to see if the child had used the Funhaler the previous day.
4. At the end of the two weeks, parents completed a second questionnaire to see if their attitudes and the child's behaviour had changed.
Common Mistake to Avoid: Don't forget that the Funhaler was compared to the child’s usual inhaler, not a placebo. This allows the researchers to see if the "fun" element specifically improved compliance.
Key Findings (The Results)
The results were very clear! The Funhaler led to much better medical adherence.
1. Usage: When using the standard inhaler, only \(59\%\) of parents had medicated their child the previous day. With the Funhaler, this rose to \(81\%\).
2. Technique: Children were much more successful at the "deep breath" technique required. Only \(10\%\) of children were successful with the standard inhaler, compared to \(80\%\) with the Funhaler.
3. Attitude: Parents reported feeling much more positive. They were less likely to "struggle" with the child, and the children were less likely to cry or resist.
Summary Table of Results:
• Medication taken: \(59\%\) (Standard) vs \(81\%\) (Funhaler)
• Correct technique: \(10\%\) (Standard) vs \(80\%\) (Funhaler)
• Parents "always" successful: \(10/32\) (Standard) vs \(22/32\) (Funhaler)
Conclusions
Chaney concluded that Operant Conditioning (using the Funhaler) is an effective way to improve health behaviours in children. By using positive reinforcement (the whistle and spinner), children learned to use their medication correctly without needing to be nagged or forced.
Evaluation (The "Critical Thinking" Bit)
Strengths
• Ecological Validity: Because the study took place in the children’s own homes, the behaviour was very natural.
• Practical Application: This study is incredibly useful! It shows how we can design medical devices to help people stay healthy by making them rewarding to use.
Weaknesses
• Social Desirability: Since parents filled out the questionnaires, they might have lied (or exaggerated) to make themselves look like "good parents."
• Sampling Bias: The sample was quite small (\(n = 32\)) and only from one area in Australia, which might make it hard to generalise the results to everyone.
Did you know? This study is often praised for being ethical. The researchers obtained informed consent from the parents, and the Funhaler actually improved the children's health, which follows the principle of protection from harm.
Quick Review: Key Takeaways
• Area: Developmental (how we change over time).
• Key Theme: External influences (how rewards shape behaviour).
• Psychological Theory: Operant Conditioning / Positive Reinforcement.
• The Result: Fun = Better medical adherence!
• Comparison: While Bandura (1961) showed how children imitate models, Chaney (2004) shows how children respond to consequences.
Don't worry if the percentages seem hard to remember at first—just focus on the fact that the Funhaler was significantly more effective than the standard inhaler in every category!
