Moro reflex - answer-a startle response in which the infant arches his back and throws out his arms and
legs. The infant behaves much as we would if we felt like we were falling and tried to grab something to
protect ourselves. Thus, some researchers believe that this reflex has a survival value.
Rooting reflex - answer-involves the baby turning her head when her cheek or mouth is touched. It
presumably aids feeding as the infant finds something to suck.
Grasping reflex (palmar grasp) - answer-most adults know that placing a finger in an infant's palm will
trigger the grasping reflex. This grasp can be extreme.y strong! It appears to be a stepping stone to
additional motor development, as when an infant becomes able to grasp things voluntarily.
Babinski reflex - answer-when the sole of the foot is firmly stroked, the big toe bends back toward the
top of the foot and the other toes fan out. This is a normal reflex up to about 2 years of age.
Stepping reflex - answer-involves the infant making stepping motions when held above a surface. Again,
it may serve as a building block for future motor development.
