Bandura et al. (aggression)

Welcome to the World of Bandura!

Ever wondered why children sometimes copy what they see on TV or how they pick up habits from their parents? In this chapter, we explore a famous study by Albert Bandura and his colleagues from 1961. This study is a cornerstone of the Learning Approach in psychology. We are going to look at how aggression isn't just something we are born with—it’s something we can learn by watching others!

Don't worry if this seems like a lot of information at first. We will break it down piece by piece so it makes perfect sense.

The Big Idea: The Learning Approach

Before we dive into the study, remember two main assumptions of the Learning Approach:

1. We are born as a "blank slate" (Tabula Rasa). Everything we become is shaped by our environment.
2. Behaviour is learned through Social Learning, which means we learn by observing others and imitating them.

1. The Background: Why did they do this study?

At the time, many people thought that watching aggression would actually help people "get it out of their system" (this is called catharsis). Bandura disagreed! He believed that if children saw an adult acting aggressively, they would be more likely to act that way themselves. This is called Social Learning Theory.

Quick Review: Social Learning Theory = Observation + Imitation.

2. The Aims

Bandura wanted to test four main hypotheses (predictions):

1. Children who see an aggressive model will imitate that aggression.
2. Children who see a non-aggressive model will be even less aggressive than those who saw no model at all.
3. Children are more likely to imitate same-sex models (boys copy men, girls copy women).
4. Boys will generally be more aggressive than girls, especially in physical aggression.

3. The Procedure: What actually happened?

The Participants (The Sample)

There were 72 children (36 boys and 36 girls) from the Stanford University Nursery School. Their average age was about 4 years old.

The Setup

The researchers used a Laboratory Experiment. They matched the children in groups based on how aggressive they already were (this is called a Matched Pairs Design). This ensured that one group didn't just happen to have all the "naturally" angry kids!

Stage 1: Watching the Model (Modeling)

The child was taken to a room to play. In the corner, an adult (the model) was also playing. Depending on the group the child was in, the adult did different things:

Group A (Aggressive): The adult spent 10 minutes attacking a 5-foot tall inflatable "Bobo Doll." They punched it, kicked it, sat on it, and hit it with a mallet while saying things like "Pow!" and "Kick him!"
Group B (Non-Aggressive): The adult played quietly with Tinkertoys and ignored the Bobo Doll.
Group C (Control): These children saw no model at all.

Stage 2: The Frustration Room

To make sure the kids were in a "ready to be aggressive" mood, the researchers took them to a room with very pretty toys. But after two minutes, they told the children they couldn't play with them because they were "the best toys" and reserved for other children. (Think of it like being told you can't have your favorite snack right after seeing it—it makes you a bit grumpy!)

Stage 3: Testing for Imitation

The child was then taken to a final room containing both aggressive toys (mallet, Bobo Doll, peg board) and non-aggressive toys (tea set, crayons, farm animals). Researchers watched through a one-way mirror for 20 minutes and recorded what the child did.

F - Frustration (Get Annoyed)
I - Imitation (Copy)
Just remember: My Friend Imitates!

4. The Results: What did they find?

The Aggressive Group: Children who saw the aggressive model were significantly more aggressive than the other groups. They copied the exact same physical and verbal acts they saw the adult do!

Gender Differences:
- Boys were more likely to imitate physical aggression.
- Girls were more likely to imitate verbal aggression.
- Children were much more likely to copy a same-sex model. For example, boys copied the "tough" male model more than the female model.

The Non-Aggressive Group: These children showed very little aggression, though not significantly less than the control group.

5. Conclusions

Bandura concluded that behaviour can be learned through observation without any rewards. This supported his Social Learning Theory. He also showed that children are particularly influenced by adults of the same gender.

Key Takeaway: Watching violence doesn't help us release it; it teaches us how to be violent.

6. Evaluating the Study (Strengths and Weaknesses)

Strengths

High Control: Because it was in a lab, the researchers controlled exactly what the models did and said. This makes the study Reliable (easy to repeat).
Matching: By matching the kids for their natural aggression levels, they made sure that the "type of kid" didn't ruin the results.

Weaknesses

Low Ecological Validity: A lab is a strange place for a kid. Playing with a Bobo Doll (which is designed to be hit) isn't the same as being aggressive in real life.
Ethics: Is it right to intentionally make children frustrated? Or to teach them how to hit things? Many psychologists argue this study caused psychological harm to the children.

Common Mistakes to Avoid

Mistake 1: Thinking the kids were rewarded for being aggressive. Actually, they were never given prizes; they copied the behaviour just by watching.
Mistake 2: Forgetting the "Frustration" stage. This stage is important because it ensured all children were in the same emotional state before they were tested.
Mistake 3: Saying the Bobo Doll was a real person. It was an inflatable doll! This is a common point used when discussing if the aggression was "real" or just "play-fighting."

Quick Review Quiz (Mental Check)

1. What is the name of the doll used in the study? (Bobo Doll)
2. How many children were in the study? (72)
3. Did the kids copy same-sex or opposite-sex models more? (Same-sex)
4. Which approach does this study belong to? (Learning Approach)

You've got this! Bandura's study is all about the power of "Monkey see, monkey do." Keep that simple analogy in mind, and you'll do great!
