SEX DIFFERENTIATION OF MORPHOLOGICAL CHARACTERISTICS AND MOTOR SKILLS IN PRESCHOOL-AGED CHILDREN

The research was conducted with the aim of determining preschool-aged children’s sex differentiation using the multivariate and univariate variance analyses (MANOVA/ANOVA). A battery of measuring instruments comprising 17 variables (8 morphological characteristics variables and 9 motor skills variables) was carried out on a sample of 69 children (49 boys and 20 girls), aged 5 and 6, from the Primorje-Gorski Kotar County in the Republic of Croatia. The results showed that, between boys and girls of this age, there are multivariate statistically significant differences in arithmetic meanings at the level of p = .022 in the entire system of morphological and motor variables, whereas univariate values did not show a statistical significance. The conclusion is drawn that in the morphologic space in children between the ages of five and six years, there are quite equal developmental processes based on sex differentiation and genetic determinations (4:4) ; however, this is more pronounced in the motor space in favor of the girls (2:7) at this age.
