Some Psychological Test Characteristics of Klinefelter's Syndrome

Abstract

Males with chromatin positive Klinefelter's syndrome are observed to have one or more extra X chromosomes within their cells. Diagnosis is by buccal mucosa smear and chromosome analysis. Clinically they have delayed puberty, abnormal physique, small testicles and little facial hair. This paper presents some observed differences between Klinefelter patients who were being treated in subnormality units and other patients not having the condition but with similar I.Q.s.
