Quizplus · Accepted Answer

The studies of infant stepping behavior on a treadmill have shown that the pattern of alternating steps on each leg precedes the ability to walk independently. This means that infants as young as a few months old can display the basic stepping pattern while being supported on a treadmill, even if they cannot walk on their own yet. Option B is incorrect because infants still need support when learning to walk, and cannot do so without assistance. Option C is incorrect because infants can track moving objects and adjust their movements accordingly. Option D is also incorrect because infants typically show an eagerness to take steps and explore their environment when given support.
