Rey-Osterrieth Complex Figure Test (Rey test) was administered to autistic adults with mild to moderate mental retardation (autism group) and normal university students (student group). While all subjects could executed on the copy trial of the Rey test, some autistic individuals with the moderate mental retardation failed to execute on the 3-minutes delayed recall trial. No significant differences existed between both groups on Copy-ACC, Copy-ORG, and Copy-time, as well as Recall-ACC and Recall-time, indicating that these variables is not sensitive to the problems of planning possibly existed in the autism. The autism group showed significantly higher score of S3 among 6 sections of the Copy-ORG than the student group and this finding was interpreted in terms of the weak central coherence of the autism. The Copy-ORG was revealed to be positively and significantly correlated with the Recall-ACC in the student group. This means that, in normal people, copy organization strategy can predict the performance of the recall. Nevertheless, on the other hand, the autism group showed a negative and nonsignificant correlation between the Copy-ORG and Recall-ACC. Then it was concluded that the experience of the copy organization has no facilitative effects on the encoding of the complex figure in the autism.
