Split-brain research Flashcards
biopsychology
Who are the participants in split-brain research?
Split-brain patients, they have had a corpus callostomy usually to treat conditions such as epilepsy
What does a corpus callostomy result in?
The two hemispheres can no longer communicate with one another
Who conducted split-brain research?
Sperry and Gazzaniga did the case of WJ
What was the procedure of WJ’s case?
Stimuli was flashed into either the right or left field of vision and WJ had to press a button every time this happened and was asked what he saw
What were the findings of WJ’s case

Indicating that the right hemisphere had noticed the stimuli but as he wasn’t able to communicate what he saw because the right and left hemisphere couldn’t communicate.
What’s a strength of the split-brain research?
Many other studies have found similar results - P.S. 13 year old boy - supports earlier findings - high reliability
What’s a limitation of split-brain research?
nature of ample sizes- patients have different degrees of damage - cannot be certain the findings apply to others
