Comparisons for Psychomotor Tasks: Grade and Sex of Secondary School Youths

Abstract

Youths in Grades 7 through 10 ( N = 815) were tested on simple reaction time, pursuit rotor, hand tapping, or arm-hand steadiness tasks. The results, which provide normative data, show that all four tasks are grade-or age-dependent; subjects in higher grades performed better than those in lower grades. Reaction time and hand tapping were sex-dependent; boys scored better than girls. An interaction of sex × grade was observed for time on target on the pursuit rotor; boys were better in Grades 7 through 9 while girls were better in Grade 10.
