Sex Differences Among Personality Correlates of Mathematical Ability in High School Seniors

Abstract

To help explain female inferiority in mathematical performance, sex differences in personality correlates of mathematical ability were examined. Three instruments, Rotter's I-E Scale, Miller Adult Locus of Evaluation Scale, and Byrd's Attitude Concerning Life and Self were administered to measure four personality factors: locus of control, locus of evaluation, identity confusion associated with resolution of the adolescent identity crisis, and self-esteem. Each personality score was correlated separately by sex with Scholastic Aptitude Test mathematical and verbal scores. The sample included 68 females and 63 males, randomly selected from college-bound seniors in a predominantly white, middle-class, suburban high school, chosen to limit the effects of social, economic, racial and educational differences. Two variables were partialed out for control purposes: number of mathematics courses completed and IQ (Otis-Lennon Mental Ability Test). For females only, internal locus of control and self-esteem were significant correlates of mathematical ability, and were seen as facilitators of female mathematical functioning in the face of environmental impediments to female mathematical performance.
