title: Age changes in assembly performance: a component analysis.
abstract: 100 children from Kindergarten to Grade 9 (i.e., 5 to 15 yr.) performed a one-handed manual dexterity assembly task. The videotaped performances were analyzed for the components, Grasping, Transporting, Positioning, Reaching, and Pauses. All five components contributed significantly to the improvements in the lower grades. The Grasping component deteriorated significantly in the older children, but Reaching and Positioning continued to improve up to Grade 9. There were no sex differences.
