Background: Human brains are divided into hemispheres; a left hemisphere & a right hemisphere. This division of tasks between the hemispheres is called lateralisation of function. They are joined by the corpus callosum.
AIM: to investigate the effects of hemisphere deconnection & to show that each hemisphere has different functions
METHOD: quasi experiment
SAMPLE: 11 'split-brain' patients
One task was to blindfold one of the participant's eyes & asking them to fixate with the other on a pointon a screen. They would then project a stimulus on either side of the fixation point. The time is so small to ensure that the participant does not have time for eye movement as this would 'spread' the information across both sides of the visual field & therefore across both sides of the brain.
Another involved asking patients to respond to tactile information. This involved presenting a stimulus to one of the hands of a split-brain patient so the participant could not see the stimulus & then asking the participant to name it
