Tap to reveal answer

Answer

The Babinski reflex occurs when a baby moves his or her big toe upward in response to feeling a stroke on the bottom of his or her foot. The other three reflexes described in the answer choices all have different names. When something touches the roof of a baby's mouth, the baby will suck, which is referred to as the sucking reflex. The walking/stepping reflex is when a baby makes a stepping motion after feeling one of his feet touch a flat surface. Finally, the palmar grasp reflex is when a baby grasps his hand in response to feeling a stroke on his palm.
