Comparing
Adolescent and Middle-age Groups on Spatial Task Performance: A
Developmental-differentiation Approach
S. K. Kunjayi |
Adolescent
boys and girls were compared with middle-aged men and postmenopausal
women on their performance on 3-dimensional space perception test.
Results indicate that sex difference was evident only for the adolescent
group and not for the middle-aged. Adolescent boys performed significantly
better compared to girls. Age difference on spatial task performance
was obtained only for males and not for females where postmenopausal
women outperformed adolescent girls. Findings are explained in terms
of progressive hemispheric lateralization and psychological differentiation
across the life span. Key words: spatial ability, sex differences, age differences, life span development, lateralization |
