Recall of the Rey Complex Figure (RCF) by patients with left (N = 26) or right (N = 18) temporal lobe epilepsy was scored in terms of the qualitative approach developed by Loring, Lee, and Meador. Patients with right temporal lobe epilepsy exhibited significantly more qualitative errors on recall of the RCF than patients with left temporal foci, whereas standard RCF scores failed to differentiate the groups. A linear discriminant function analysis showed that 66% of patients were correctly classified into lateral focus groups on the basis of qualitative scores, with a sensitivity of 50% and specificity of 77%. Although unsuitable for clinical use in its present form, the qualitative approach appears to be a promising one. The findings offer support for the position that some aspects of nonverbal memory are critically dependent on the integrity of the right temporal lobe. The implications of this for reorganization of cerebral representation are examined.
