Left nd right h of brain are responsible for different functions
The 2 hemispheres each have?
Diff functions nd roles
Left hem is responsible for?
Language
-Broca’s area= speech production
-wernicks area= understanding language

Contralateral wiring
The left hem receives info from?
Right visual field

AO3 strength
P-sperry,using split brain pt w severed corpus collosum
E-found= ppt shown image of object to RVF, name it verbally
E-presented to LVF, not name it verbally but could identify obj pointing
L-supp Brain lateralised resp for diff functions left for lang. inc validity
AO3 limitation
P-individual diff in ppt, how lateralised their Brain was
E-degree which corpus collosum was severed for each ppt varied greatly, some greater disconnection between 2 H than other
E-mean= may still be some ability to communicate between 2 H
L-weakness may. It be measuring true effects coz of counfounding variables reducing internal val
Discusssion AO3
EB-lacks pop val
AO3 limitation
EB suffered brain damage removal of his left hem
Despite manage to regain language ability
