Global/local scoring modifications for the Rey-Osterrieth Complex Figure: relation to unilateral temporal lobe epilepsy patients.
Observation of figural reproductions of right temporal lobe epilepsy (RTLE) patients have revealed overall configuration errors, whereas in left temporal lobe epilepsy (LTLE) patients, the global aspect of performance is generally preserved. This study compared performance of individuals with temporal lobe epilepsy (LTLE, n=83; RTLE, n=63) on a global/local modification of the Rey-Osterrieth Complex Figure Test (RCFT). In Phase I, neuropsychologists (n=6) and neuropsychology fellows (n=3) completed a survey identifying the global and local aspects of the RCFT. Questionnaire responses were used to categorize a list of global and local items (five global, five local) for re-scoring the protocols of TLE patients during study Phase II. Results showed that the RTLE and LTLE groups were not differentiated according to the global or local indices F(1,141) = .385; p = not significant. There were lower local scores for both groups in the copy F(1,142) = 5.23; p = .024, immediate F(1,142) = 445.26; p < .001, and delay trials F(1,142) = 427.82; p < .001, indicating less retention of local information over time. Results suggest general declines in figural memory for local stimulus properties in both unilateral TLE groups. However, this relationship was weakened after controlling for global and local item verbalizability.
