Draganski et al's study Flashcards
(9 cards)
What is the aim?
To see if brain structure would change when learning a simple juggling routine
What experimental method was it?
Lab experiment
Who were the participants?
Volunteers who had no prior experience with juggling
What was the experimental design?
mixed design (independent measures and repeated measures design)
What was the IV?
Jugglers and non-jugglers
What was the DV?
Changes in brain structure
What was the procedure?
2 groups of participants. One group that were asked to juggle for 3 months and then stop juggling for 3 months. The other group were told not to practice juggling at all. At the start of the experiment, an MRI scan was taken for every participant. Then after 3 months (where one group was practicing and the other was not) another MRI scan was taken. Then again after another 3 months where none of the participants were juggling
What were the results?
At the start of the experiment, there were no differences in the MRI scans between all participants. After 3 months when the scan was taken again, the group that had been juggling had an increased amount of grey matter in their mid-temporal area in both hemispheres of the cortex which is responsible for coordination and movement, in comparison to the other group. After 6 months where none of the participants were juggling, the juggling group still had more grey matter than the other group, but it was less than when they were practicing.
What was the conclusion?
The results show that there is a cause-and-effect relationship between learning and brain structure
