title: Melanin as a predictor in the acquisition of developmental skills.
abstract: Seventy-two subjects were randomly drawn across grades K-12 and administered an instrument designed to measure developmental skills within seven skill area categories. A three-way ANOVA, fixed effects model, was used for data analysis. Subjects were blocked by eye color, sex, and grade level for the purpose of investigating the relationship between eye color and sex to self-paced and reactive behaviors. Significant differences were obtained on the main effect of eye color in five of the seven categories examined. There were three significant first order interactions (sex X eye color) and one three-way interaction. The findings support the hypothesis of Worthy that eye color is a dependable predictor of subjects' general behavioral competency area (self-paced or reactive) and adds considerable support for his thesis that self-paced and reactive behaviors are to some degree inherited.
