Copying strategies and memory on the Complex Figure Test in psychiatric patients.
We assessed three copying strategies on the Rey-Osterrieth Complex Figure Test among 50 psychiatric patients. The strategies were featural (detail-focused), contextual (framework-focused), and mixed. Reliable classification of each patient's copying strategy showed 7 patients used a featural and 7 patients used a contextual strategy. The remaining 36 used a mixed strategy involving both elements. Analysis indicated that patients who met DSM-III-R criteria for schizophrenia tended to use a mixed strategy. Nonschizophrenic patients also favoured the mixed approach. Moreover, when subjects were divided into groups based on their strategies, there were no differences in copying accuracy. However, the groups differed on immediate and delayed recall of the Complex Figure Test. Patients who adopted a featural strategy on the copy trial had the lowest recall scores. "Process" variables may be important in understanding neurocognitive functioning in schizophrenia; however, there is little evidence that schizophrenic patients use copying strategies consistent with lateralized impairment of brain function.
