Abstract:
Members of over 100 families were administered the Wechsler Adult Intelligence Scale (WAIS) as well as various psychometric tests of personality. Individual cognitive and personality measures often were associated. Parent personality scale scores often were associated with offspring WAIS scores and vice versa. Stepwise multiple regressions demonstrated that knowledge of parental personality test scores substantially increased the predictability of offspring WAIS scores.
