- A. The sequence and rate of motor development are consistent among infants
- B. Movement emerges from an interaction and cooperation of many systems
- C. Movement progresses from primitive reflexes to voluntary control
- D. Low-level skills are prerequisites for certain high-level skills
Correct Answer: B
Rationale: Neuromaturational theory emphasizes that motor development progresses in a predictable sequence and rate, starting from primitive reflexes to voluntary control. It also states that low-level skills are foundational for higher-level skills. However, the theory does not support the idea that movement solely emerges from an interaction and cooperation of many systems, as it focuses more on the hierarchical development of motor skills.
