Performance differences for 120 elementary school children from three grade levels were identified using a novel motor skill. Females performed the tasks faster and with less variable error than males, and the older children performed better than the younger subjects. These results provide support for a developmental progression of motor skill, based upon maturation and environmental influence.
使用一种新颖的运动技能对来自三个年级的120名小学生的表现差异进行了识别。女生完成任务的速度比男生快，且误差变量比男生小，年龄较大的孩子比年龄较小的孩子表现更好。这些结果为基于成熟度和环境影响的运动技能发展进程提供了支持。
