Abstract
In 1984 I had the opportunity to travel to New Zealand for two years to collect data for a program of research into predictors of delinquent behavior. I had proposed to investigate in particular the relationship between self-report delinquency and neuro-psychological variables, and had identified an ongoing longitudinal study of the health and social development of a birth cohort of 1037 New Zealand children that would be the ideal context for my investigation. Prospective data were to be made available to me concerning the subjects’ perinatal, medical and neurological health, their educational achievement, and childhood behavior disorders. The subjects would become 13 years old soon after I arrived, a suitable age to measure both emerging delinquency and neuropsychological status.
