Step 1:I'll solve this problem step by step, focusing on the concept of cephalocaudal development.
Step 2:: Understanding Cephalocaudal Development
Cephalocaudal development is a principle of growth and motor skill development that describes how human development proceeds from the head (cephalic) region downward to the feet (caudal) region. This means that infants typically gain control of head and upper body movements before gaining control of lower body and extremity movements.
Step 3:: Analyzing the Options
Let's examine each option through the lens of cephalocaudal development: A. Infant gains control over the arms before the hands - This follows the cephalocaudal principle, as control of larger muscle groups (arms) typically precedes control of smaller muscle groups (hands) B. Infant can sit up before it can walk - This also demonstrates cephalocaudal development, as sitting requires core and upper body strength before leg movement C. Infant can roll over before it can grasp a small object - This shows progression from larger muscle movements (rolling) to more precise fine motor skills D. Infant can hear before it can see - This is a sensory development sequence, not a motor skill progression
Step 4:: Identifying the Best Example
The most precise example of cephalocaudal development is Option A, where the infant gains control of arms before hands.
Final Answer
Infant gains control over the arms before the hands. This answer best illustrates the cephalocaudal principle of development, showing progression from larger muscle groups to more refined motor skills in a top-down sequence.
