Correct Answer - Option 3 : Development proceeds from the center of the organism to its periphery.
Motor development refers to the development of control over body movements. The child’s capacity to sit, stand, walk, hold an object, eat, write, climb stairs, run, etc. is included in motor development.
Motor development makes the child mobile, increases his/her range of activity, and helps him/her to explore the surroundings. This also helps in cognitive development.
The physiological development of the human being manifests itself in a universal and orderly process of structural change marked by two interrelated kinds of sequence: (i) The Cephalocaudal and (ii) The Proximodistal
The Proximodistal- In this,
- The middle part of the body develops quicker than the outer part of the body.
- The growth of tissue and structure that is closer to the center of the body is a little faster than the maturation of tissues and systems that are located in its periphery.
- First, whole arm or leg movements are seen, then elbow and knee joint control, and finally the specialized reaching movements of the fingers.
Cephalocandal sequence-
- As the name indicates, is a progression of differentiation and structural maturation from the head, through the trunk, to the extreme parts of the body.
- This means that the infant’s brain and head grow faster and reach maturity earlier than visceral organs.
Thus from the above-mentioned points, it is clear that the Proximodistal principle of motor development means that development proceeds from the center of the organism to its periphery.
