Studied the relation between cognitive functioning, as evidenced by IQ and achievement test performance, and Diagnostic and Statistical Manual of Mental Disorders (DSM-III) categories of conduct disturbance, using data from Black adolescents who were members of collaborative perinatal project from birth to age 7 yrs.

The reaction range implies an upper and lower limit for phenotype expression possible from a given genotype.
