Abstract
Investigated personality and cognitive differences of male students according to their self-reported eye color, ethnic origin, family size, and birth order. It was hypothesized that light-eyed Ss would be more successful in cognitive tests and more emotionally stable than dark-eyed Ss. 144 Sephardi (Eastern origin) and 180 Ashkenazi (Western origin) Jewish males aged 20-26 yrs served as Ss. Results show that ethnic origin accounted for the variance on cognitive performance and neuroticism and also for environmental variables such as family size and birth order. It is concluded that eye color should be studied in the context of other social-psychological variables.
