Abstract: To investigate auditory spatial and nonspatial short-term memory, a sound location discrimination task and an auditory object discrimination task were used in patients with medial temporal lobe resection. The results showed a double dissociation between the side of the medial temporal lobe lesion and the nature of the auditory discrimination deficits, suggesting that right and left temporal lobe structures are differently involved in auditory spatial and nonspatial short-term memory.
