Perseveration In Organic And Non-Organic Mentally Retarded Children

In order to compare perseverative tendencies of organic and non-organic S's, twenty mentally retarded institutionalized central nervous system damaged patients were compared with twenty non-organic institutionalized mentally retarded patients. S's were paired with regard to age, sex, and IQ. The findings of earliest research indicated that the perseveration tendency is greater in organic than in non-organic S's.
