Sperry - IVs
Patients with CoMM-iSS-uru-tom-y
Sperry - DV
How they perform in the Stimuli tests
Sperry - Aim
- Investigate effects of Commissurotomy
- To Map Lateralisation
- Show information can be Restricted to One Hemisphere
Sperry - Method
- Participants tested with tests that Displayed Information to Only 1 Hemisphere
- Wrote Down or Said what they Saw/Felt
Sperry - Sample
- 11 patients of CoMM-iSS-uro-tom-y
- Due to Epilepsy
- Opportunity
- Ethnocentric (English Speaking)
Sperry - Design
- Quasi (ppl already had the surgery)
- Lab Experiment
Sperry - Procedure
- Expose 1 or 2 Hemispheres to a Stimulus & elicit a Response
- Stimuli were either:
> Visual
> Tactual (touch)
> Auditory
Sperry - Applications
Indication of Brain Surgery Safety
Sperry - Link to Theme
- Illustrating the Function of the Corpus Callosum between Hemispheres
Sperry - Link to Area
- Studies how a Change in Brain Structure can effect Behaviour
SPERRY - Localisation
Limitation of a particular Brain Function to a particular Structure
SPERRY - Lateralisation
Limits a particular Function to One Hemisphere
SPERRY - CoMM-iSS-uro-tom-y
Where Brain Hemispheres have been separated (cut Commissures)
SPERRY - CoMM-iSS-ur-es
Structures that join Hemispheres consisting of nerve fibres
SPERRY - Visual Fields (RVF), (LVF)
The part of your Unfocused Vision to the Left or Right respectively

CASEY - Sample
- 562 Pupils aged 4
- Stanford’s Bing Nursery School
- 155 Repeated in their 20s
- Gynocentric
CASEY - Experiment 1
- 59 Participants
