What characterizes sensorimotor development in early infancy?

• A. Reflexes that dominate movement and behavior, indicating neurodevelopmental maturation.
• B. Deliberate planning and goal-directed movement.
• C. Abstract reasoning and symbolic thought.
• D. Fine motor precision without reflexes.

Answer: (A)

In early infancy, movement is driven by reflexes—automatic responses to sensory input that are the building blocks for later voluntary control. Newborns rely on reflexes such as rooting, sucking, grasping, and the Moro reflex to interact with the world, and these patterns reflect immature neural pathways. Over time, these reflexes become integrated and voluntary, goal-directed actions emerge, but at this stage the behavior is still dominated by automatic patterns rather than deliberate planning. Abstract reasoning and symbolic thought don’t appear yet in this period, and fine motor control with precise, reflex-free movements develops later. So, reflexes dominating movement and behavior best characterizes sensorimotor development in early infancy.
