Question | Answer |
---|---|
What was the AIM of Draganski's study? | To study if the brain can change structure in response to environmental demands |
What was the METHOD of Draganski's study? | Random sampling experiment |
What was the PROCEDURE of Draganski's study? | He made a group of non-jugglers and jugglers. He took a brain scan of everyone beforehand, then had the jugglers learn how to juggle for 3 months. Then he scanned them again, told them to stop juggling, then scanned them again 3 months later. |
Why did Draganski perform a brain scan after 3 months of no activity? | In order to see if the juggling had changed their brain structure in any way. |
What were the RESULTS of Draganski's brain scans? | Draganski found that the juggling group had significantly more grey matter in their mid-temporal area than the control group, even when it shrunk |
What was the CONCLUSION of Draganski's study? | That learning a new skill leads to an increase in gray matter in the brain. |
What was the AIM of the Maguire study? | To study the relationship between the size of the hippocampus and spacial ability |
What was the METHOD of the Maguire study? | Quasi-experiment(people aren't randomly assigned to groups, so it can't prove cause and effect) |
What was the PROCEDURE of the Maguire study? | 16 healthy right-handed male London taxi drivers were given MRIs. Those scans were compared to scans of 50 healthy people in other professions. |
What were the RESULTS of the Maguire study? | London taxi drivers had similar hippocampus size compared to control groups. However, the control group's front of the brain was larger, and the taxi drivers had a larger back of the brain. |
Why is there NO CONCLUSION in the Maguire study? | There is no conclusion in the Maguire study because it is a quasi experiment, therefore you can't prove a definite cause. |
