Which statement about Phase 4 is accurate?

Which statement about Phase 4 is accurate?

• A. Sensory integration is typically well developed by ages 4 to 5
• B. It occurs only after adolescence
• C. It is achieved by age 2
• D. It is unrelated to age

Answer: (A)

Phase 4 reflects the point in development when sensory integration has matured enough that complex, coordinated responses are typical. By about ages 4 to 5, most children show well-organized processing across senses, better modulation, praxis, and bilateral coordination, which supports functional participation in classroom routines and social play. That’s why the statement that sensory integration is typically well developed by ages 4 to 5 is the best choice. The other options don’t fit because sensory integration development is not delayed until adolescence, not completed by age 2, and it does relate to age—development progresses through early childhood toward that mature integration.
