Objective: Neuropsychologists (NP) have long labored over scoring the Rey Complex Figure Test (RCFT) in spite of the fact that “deficits” on this test are often observable to the “naked eye.” It is known that standard scoring systems are ineffective for lateralizing dysfunction associated with temporal lobe epilepsy (TLE). Development of more “qualitative” scoring systems has also been ineffective. This study examined accuracy of lesion lateralization in TLE using basic, subjective visual classifications of RCFT by experienced NPs. Method: This retrospective study examined data from 60 patients (60% female; M-age = 36yrs; M-educ = 13.9yrs; 72% R-handed) classified through VEEG as right (n = 35) or left (n = 25) TLE who completed RCFT during a presurgical evaluation. Copy and delayed recall (DR) scores were computed using standard criteria (SC) and converted to z-scores; a cut-off of z <−2 (‘impaired’) was classified as RTLE. Copy and DR productions were also classified as RTLE, LTLE, or unclear by three board-certified NPs. Inter-rater agreement was excellent (K = .86). Results: There were no differences in SC scores between RTLE and LTLE for copy and DR (p's = .64, .57). For RTLE cases, 62% were correctly lateralized using NPs ratings, while only 48% were correctly lateralized using SC. For LTLE cases, 28% and 49% were correctly classified with NPs ratings and SC, respectively. In sum, lateralization accuracy was equal (48%) for SC and NPs. Conclusion: There was a non-significant trend for NPs to lateralize RTLE more accurately using subjective ratings compared to SC, while the opposite was true for LTLE. Overall, quantitative scoring was no better at lateralizing TLE patients than NPs basic, subjective classifications.
