An infant transitioning from putting her hands in her mouth to placing her feet in her mouth illustrates which concept of development?

  1. Proximodistal

  2. Cephalocaudal

  3. General to specific

  4. Sterognosis

The correct answer is: Cephalocaudal

The concept of development illustrated by an infant transitioning from putting her hands in her mouth to placing her feet in her mouth is primarily related to cephalocaudal development. Cephalocaudal development refers to the pattern of growth that proceeds from the head to the lower parts of the body. In this case, the infant is demonstrating increasing motor control and awareness of her body's parts, starting with her hands, which are closer to her head compared to her feet. This pattern is typical in infant development; as they gain more control over their head and upper body, they naturally progress to manipulating and exploring their lower body. While the other concepts, such as proximodistal and general to specific development, describe important patterns in growth, they do not fit this scenario as well as cephalocaudal development. Proximodistal growth refers to development from the center of the body outward, and general to specific refers to a progression from broad skills to more refined abilities. Sterognosis, on the other hand, involves the ability to recognize objects through touch, which is not relevant to this particular example. Thus, the correct framework for understanding this developmental milestone is rooted in the cephalocaudal principle.
