Rosenzweig, Bennett and Diamond's study
To investigate the effect of rat's brain growth and chemistry in different environments
Aim
Three male rats were chosen at random and allocated in different conditions
Method
The brains of rats in enriched environments were different from the brains from the rats in poorer environments
Results
Conclusion
The enriched environment had a great impact on the cerebral cortex of the rats’ brains. Their neurons and synapses grew and the chemical activity of the brain also increased.
Evaluation
Limitations
- Ethical issues as living animals are used in the study
- Rats are not identical to humans
Strengths
- Learning that brain weight cannot be changed
- Find out there is a cause-effect relationship
-Study is replicable and has been repeated several times
The brain of the rats changed depending on the condition and environment the rats were placed in
Relationship of study with brain plasticity
