Thick bundle of nerve fibres connecting the hemispheres
Sperry (1968)
Quasi experiment of 11 patients who had undergone a corpus collosotomy compared to a control, images were projected into each field of view, asked to say, pick up or draw what they saw
Left hemisphere = spoken, but not drawn or picked up
Right hemisphere = drawn and picked up, but not spoken
Gazzaniga (1983)
Patients had undergone corpus collosotomy
Found that when presented with faces, right hemisphere was more able to recognise them
Right hemisphere = facial recognition
(-) A03: Sperry's Research
Sperry used participants with varying amounts of corpus collosum cut, each participant had already undergone drug therapy and the control group hadn't had history of epilepsy; creating ungeneralisable research
(-) A03: Lack Mundane Realism
Tasks performed by Sperry and Gazzaniga were lacking mundane realism, participants lived normal lives just moving their heads side to side rather than using different fields of view
(+) A03: Methodology
Specialised and standardised procedures used to control, using fixation points where an image would pop up for 1/10 of a second so there was no time for both eyes to see, making only 1 hemisphere recieve info
