RESUMEN
Sex differences in math/spatial performance demand explanations. Within the biological view, the complexity and number of variables make the explanation difficult at best. Laterality and age of pubertal onset have been investigated prominently in this context but rarely considered as interactions in the same study. Some 468 college subjects with SAT MATH (SAT M) scores were divided into 12 groups defined by sex, laterality, and age (early, middle, and late) of pubertal onset. Significant main effects for sex and age of onset emerged, as did an interaction between lateral preference and pubertal onset. Generally males outperformed females. The combination of maleness, sinistrality, and early maturation was associated with high SAT M scores. Sinistrality and late maturation among females predicted very poor math performance.

An archival study sampled personality test protocols with spontaneous handwriting specimens from 73 men and 168 women for signatures and scores on selected scales from the Minnesota Multiphasic Personality Inventory-2. Judges applied a 5-point scale to sort signatures for tidiness. Interrater agreement was .93. The mean handwriting tidiness score for men was 1.8 and 2.8 for women, a significant difference of 1 point. Correlations between handwriting tidiness and MMPI-2 scores did not support the hypothesis that erratic handwriting is associated with pathology but scores for gender role correlated significantly with handwriting tidiness. Masculine Gender Role predicted sloppy penmanship and Feminine Gender Role predicted tidy writing, independent of the writers' biological sex.
