THE EFFECT OF AGE AS A VARIABLE ON THE SCORES OF THE HARRIS-GOODENOUGH DRAWING TEST OF EDUCABLE RETARDATES.
LEVY, IRWIN S.
IN ORDER TO DETERMINE THE RELIABILITY OF PERFORMANCE OF RETARDED ADOLESCENTS ON THE HARRIS REVISION OF THE GOODENOUGH DRAW-A-MAN TEST (DAM) AND WHETHER THE DECLINE IN PERFORMANCE WHICH OCCURS IN NORMAL ADOLESCENTS AT THE MID-TEENS ALSO OCCURS WITH RETARDED ADOLESCENTS, 213 MALE AND 130 FEMALE SUBJECTS, AGED 11-20 YEARS AND WITH IQ'S OF 56-72, IN INTERMEDIATE AND SECONDARY CLASSES FOR THE EDUCABLE MENTALLY HANDICAPPED (EMH) IN NORTH CAROLINA WERE TESTED. THE DAM WAS ADMINISTERED IN GROUP FORM TO ALL THE SUBJECTS IN THEIR OWN CLASSROOMS. IT WAS READMINISTERED AFTER 7 MONTHS. OVERALL MEAN CHANGE FOR THE 343 SUBJECTS BETWEEN TEST AND RETEST WAS SIGNIFICANT (P IS LESS THAN .05). ANALYSIS OF VARIANCE PRODUCED SIGNIFICANT F-RATIOS SHOWING THAT STANDARD DEVIATIONS OF THE CHANGE DIFFERED AT VARIOUS CHRONOLOGICAL AGE GROUPS FOR THE MALES. RESULTS INDICATED THAT THE TEST-RETEST RELIABILITY WAS SIGNIFICANT (P IS LESS THAN .01). THE TEST IS USEFUL WITH EMH FEMALES TO AGE 16 AND WITH EMH MALES TO AGE 20 YEARS. ALTHOUGH THE MAXIMUM CHRONOLOGICAL AGE DIVISOR OF 15 WAS ESTABLISHED BY HARRIS, THE INTRA-SCORER RELIABILITY COEFFICIENT AFTER 6 WEEKS WAS .99. IN CONCLUSION, THE DAM TEST AS A MEASURE OF CONCRETE CONCEPT FORMATION SEEMS TO BE A RELIABLE INSTRUMENT FOR GAINING INFORMATION ABOUT MILDLY MENTALLY HANDICAPPED ADOLESCENTS. TWENTY-FIVE REFERENCES AND 19 TABLES ARE INCLUDED. (DT)
