Effects of Birth order, Sex, and Family Size on Field Dependence and Locus of Control

Abstract

The effects of birth order, sex, and family size were assessed on college students' performance on the rod-and-frame test and locus-of-control scale. No significant effects were obtained except for sex. These data were similar to other studies which failed to find any significant relationships between birth order and personality. The results were discussed in terms of current issues in the birth-order literature.
