The locus of control as measured by the Nowicki-Strickland Locus of Control Scale was investigated for 68 rural, southern elementary gifted students, ages 8 to 14 years. The scores became more internal with older ages, and the girls (n = 34) tended to have more internal locus of control across grades.
