Infants are born with many basic reflexes such as the rooting reflex
(a touch on the cheek means a turn of the head), the eye-blink reflex
(the blink of the eye protecting from bright light), and the Palmer grasp reflex (the curling of fingers when the palm is touched).
Most of these reflexes fade within six months after birth.

If the parents are warm and responsive the a sense of trust will develop. If the parents are not present or act cold then a sense of mistrust will develop.

PSYCHOSOCIAL DEVELOPMENT
(NEVID, 2012)



Infants are born with simple schema, or an organized system of actions, of basic reflexes.
