Developmental psychology = stages - Answer the physiological, behavioral, cognitive, and social changes that occur throughout human life, which are guided by both genetic predispositions (nature) and environmental influences (nurture).

This reflex is present from birth and persists throughout our lives in some form. The blink reflex is a protective response of the eyelids to potentially damaging objects around the eyes. Withdraw reflex - Answer If you poke an infant (softly) on the bottom of the foot with a sharp object, the infant will pull both legs into a crouching position, moving them away from the source of irritation. This reflex is present from birth, and it disappears as a simple reflex as the response becomes more complex with increased motor control. Grasp reflex - Answer This reflex is sometimes called the palmar reflex. When the palm of the infant's hand is touched or brushed, the hand closes in a grip. The infant's grip can be very strong. In fact, many infants can support their own weight for a short period of time. Stroking the back of the hand produces a
