* Fixed patterns of action that occur in response to particular stimulation.
* Examples are rooting, sucking and swallowing, tonic neck, startle, grasping, and stepping.
* These are not fully automatic as some occur when an infant is feeling something (ex. rooting is more likely when an infant is hungry).
* Some neo-natal reflexes disappear, but some - coughing, sneezing, blinking, and withdrawing from pain - remain throughout life.
