Final answer:
The yardstick test directly measures motor coordination, not reaction time.
Step-by-step explanation:
Motor coordination refers to the harmonious interaction of muscles and limbs during the performance of a motor skill or a complex movement. It involves the integration of sensory information, muscle contractions, and joint movements to execute precise and controlled actions. Motor coordination is crucial for a wide range of activities, from simple everyday tasks to more complex skills in sports, arts, and other domains.
The yardstick test directly measures motor coordination, not reaction time. The yardstick test involves dropping a yardstick and measuring how quickly the person can catch it. The ability to coordinate the movement of the hand and eye to catch the falling yardstick requires good motor coordination.
