Explanation:

The development of an infant's motor abilities begins with the development of reflexes at birth. These reflexes include the rooting reflex, the grasping reflex, the Moro reflex, the sucking reflex, and the Babinski reflex.

The Moro reflex is a startle reflex observed in infants when they hear a sudden, unexpected sound. It involves the extension of the infant's arms and legs followed by an embracing posture. The infant usually cries during or after the Moro reflex.

According to Piaget, the brain development of a child is the product of assimilation and accommodation. Assimilation is the addition of a new experience to the infant's existing schema. On the other hand, accommodation is the introduction of new schemas that takes place when there is a mismatch between the existing schema and the new information that has been gained.

At birth, the infant’s motor abilities are limited to (12) reflexes such as sucking, rooting, Moro, Babinski, and grasping. The (13) Moro reflex is a startle reflex. Brain development in infancy involves two processes: (14) assimilation and (15) accommodation.
