What is the common factor when considering psychomotor skills?

• A. Mental ability
• B. Weight
• C. Age range
• D. Height

Answer: (C)

Psychomotor skills hinge on development and maturation of the nervous system, which progresses with age. As people grow, reaction time, coordination, balance, and the precision of movements improve in predictable ways, making age range a consistent factor when considering how these skills are performed or taught. Mental ability touches cognitive processes and, while related to overall performance, it isn’t the defining factor for motor skill execution. Height and weight are physical dimensions that can influence certain task performances, but they don’t establish the typical level of psychomotor capability across a broad range of skills. So, age range best captures the common factor in psychomotor development and performance.
