Question

Sherri grasps for her rattle at 3 months of age but cannot quite get hold of it. However, by 11 months Sherri is holding and moving the rattle with total control. Which developmental principle does Sherri's behavior illustrate?A. the principle of hierarchical integration
B. the proximodistal principle
C. the cephalocaudal principle
D. the principle of the independence of systems

Answer 1

Answer: the principle of hierarchical integration.

Explanation: The principle of hierarchical integration in child development explains that simple skills are developed separately and independently then overtime, they are integrated into more complex skills.

Like in the question above, Sherri at 3 months old can hold the rattle but not quite comfortably (simple skill developing independently). At 11 month, she can hold comfortably and shake the rattle (simple skill developed into more complex skill).
