Question

when words were flashed on the left and on the right, why was joe unable to speak the words on the left?
his right hemisphere was detecting the words on the left, but speech is controlled by the left hemisphere.
his left hemisphere was not detecting the words on the left.
his right hemisphere was not detecting the words on the left.
his left hemisphere was detecting the words on the left, but speech is controlled by the right hemisphere.

Explanation:

This relates to brain lateralization: visual information from the left visual field is processed by the right hemisphere, while speech production is primarily controlled by the left hemisphere (Broca's area, typically in the left hemisphere). The right hemisphere cannot send the word information to the speech-controlled left hemisphere to produce spoken language.

Answer:

A. His right hemisphere was detecting the words on the left, but speech is controlled by the left hemisphere.
