Abstract:
The responses to the High School Personality Questionnaire and the Million Adolescent Personality Inventory of a series of neonatally identified 47, XXY adolescent males and age-matched controls were compared. The extra X males' results indicated that they were more assertive, impulsive and prone to conflict than controls. Individual differences in these characteristics among the extra X cases had little relationship to quality of parenting but were related to indices of pubertal development.
