A patient has an injury to the parietal lobe and has a selective deficit in processing information about the spatial location of visual stimuli.You hypothesize that this region of the brain is distinct in function from other visual areas in the temporal lobe,in which you suspect shape perception information is processed.To establish a double dissociation between the two functions and brain regions,you would need to find another person who had damage to the
A)same part of the parietal lobe but did NOT have a visuospatial deficit.
B)temporal lobe and had both visuospatial and shape perception deficits.
C)same part of the parietal lobe and had only a shape perception deficit.
D)temporal lobe and had only a shape perception deficit.

To establish a double dissociation, you need a case where damage to the temporal lobe results in a shape perception deficit without affecting visuospatial processing, which would complement the case of parietal lobe damage affecting visuospatial processing without affecting shape perception.
