Which test uses timed peg placement to evaluate dexterity?

• A. Purdue Pegboard
• B. Denver Developmental Screening Test II
• C. Bayley Scales of Infant Development
• D. Peabody Developmental Motor Scales

Answer: (A)

Timed peg placement to evaluate dexterity is best captured by the Purdue Pegboard. This test is specifically designed to quantify fingertip dexterity and hand–eye coordination by having a person place pins into small holes on a board as quickly as possible, with separate trials for one hand, both hands, and sometimes an assembly task. The speed and accuracy from these timed tasks provide a clear measure of fine motor dexterity. The other assessments cover broader developmental or motor domains rather than a focused, timed peg-placement task. The Denver Developmental Screening Test II screens overall development with a variety of age-appropriate tasks across domains, not a timed dexterity drill. The Bayley Scales of Infant Development assess cognitive, language, and motor development with a wide range of tasks, not specifically a timed pegboard activity. The Peabody Developmental Motor Scales evaluate gross and fine motor skills through multiple tasks, emphasizing overall motor ability rather than a single timed dexterity measure.
