• support from recent split brain research. gazzaniga showed that split brain participants perform better than connected control on certain tasks. they were faster at identifying odd one in an array of similar objects than normal controls. in normal brain LH better cognitive strategies watered down by inferior RH. supports sperrys findings of left and right brain distinct
• hard to establish cause and effect. behaviour of sperrys participants compared to neurotypical control group. issue is none of participants in control group had epilepsy. major confounding variable. any differences observed between 2 groups may be result of epilepsy rather than split brain. so some unique features of split brain participants cognitive abilities due to their epilepsy.
