D) infants will refuse to attempt to walk if held upright.

Question

Quizplus · Accepted Answer

The pattern of alternating steps on each leg, which is a fundamental component of walking, is present even before infants can walk independently. This has been demonstrated through studies where infants, when supported in an upright position on a treadmill, will begin to make stepping motions with their legs. This indicates that the neural mechanisms for walking are present early in development, even if the muscles and coordination are not yet developed enough for independent walking.
