Explanation:

The proximodistal principle states that motor development progresses from the center of the body outward, starting with larger, whole-body movements before fine, precise movements. Alexander first uses his whole fist (a larger, more proximal movement) and later develops the ability to use his thumb and forefinger (a fine, distal movement), which matches this principle.

Answer:

proximodistal
