In the context of various principles of child development, which of the following statements is most scientific and accurate regarding the 'Cephalocaudal' and 'Proximodistal' trends that fall under the 'Principle of Directional Trend'?

Understanding the Principle of Directional Trend

The 'Principle of Directional Trend' is a fundamental concept in child development and growth. It comprises two primary directions:

• Cephalocaudal Trend: Development proceeds from head to toe. Infants gain control over their head and neck movements before they learn to crawl or walk.
• Proximodistal Trend: Development proceeds from the center of the body outward toward the extremities. Children gain control of their torso and shoulders before mastering fine motor skills in their hands and fingers.

Therefore, option (b) correctly defines both academic terms within child development.
