Results: Children who observed aggressive models were more likely to exhibit aggressive behavior towards the Bobo doll than children who observed non-aggressive models or those in the control group.

Conclusion: The study provided strong evidence for the role of observation and imitation in learning aggressive behavior.

Strengths: The study used a controlled experiment, allowing researchers to manipulate the independent variable (model behavior) and measure the effect on the dependent variable (child behavior).

The study involved a relatively large sample size, increasing the generalizability of the findings.

Weaknesses: The study's findings may be limited to the specific behavior (aggression) and the specific context (playing with a Bobo doll).

The study used children as participants, which may not be generalizable to adults.

Psychology Investigated: The use of classical conditioning to treat phobias.

Background: Classical conditioning theory suggests that phobias can develop through association between a neutral stimulus and an unconditioned stimulus.

Aim: To use classical conditioning to treat a child with a phobia of buttons.

Procedure: The study involved a series of therapy sessions.

The therapist used a hierarchy of stimuli, starting with buttons that were furthest from the child's phobia (e.g., buttons on a picture) and gradually working towards buttons that were more similar to the child's phobia (e.g., buttons on a garment).

The therapist used a combination of relaxation techniques and exposure therapy to help the child overcome their fear.
