Sex and eyedness in a sample of Turkish high school students

The relationship of sex with eyedness was examined in 176 boys and 129 girls ages 15 to 21 years (M = 16.9 yr., SD = 1.8) in Turkish high schools. Sex was significantly associated with handedness; the rate of left-handedness was 10.8% in boys and 2.3% in girls and was not related to eyedness. Rate of left-eyedness in the sample was 7.9% for boys and 8.5% for girls. One may wonder whether eyedness shows a reverse sex effect, less than handedness, but methods of measurement must be compared.
