Abstract: Tests of facial recognition and spatial learning were administered to presurgical patients with unilateral temporal lobe EEG foci. Right temporal lobe patients obtained lower facial recognition scores than let temporal lobe patients. The groups performed equally on the spatial learning test. A factor analysis revealed two independent factors: a general visuospatial factor and a more specific facial identification faster. The findings provide support for the existence of two dissociable visual processing systems. Memory impairments associated with right temporal lobe dysfunction may be characterized as an impairment in a ventral visual processing system responsible for facial memory and pattern recognition.
