Which developmental principle is demonstrated by the infant motor milestones of lifting one's head, pivoting the upper body, sitting, and finally standing?

cephalocaudal sequence

Explanation:

The cephalocaudal theory refers to the general pattern where the greatest growth occurs at the top of the body, i. e. the head, and gradually the physical development shifts downward: e. g. back, arms, spine, etc. It is a general pattern of physical and motor development with a continuum from infancy to puberty and follows a development pattern from head-to-toe.
