Question 3

research

Answer 3

sperry gathered 11 ppts who had undergone a corpus callosotomy for epilepsy.

testing LH- there was a black cross in the middle of the white screen to divide VF. he flashed a word/image on the right visual field for 0.1 secs and same for left (while other eye was blindfolded)
findings- since the language centre is on the left hemisphere, the ppt could verbally say the word when shown to the right visual field but not when shown to the left.
therefore the LH is responsible for the language centre.
