AP PSYCHOLOGY

Detailed explanation-1: -A dramatic reflex during these first few weeks is the Moro reflex. If your baby’s head shifts position abruptly or falls backward–or if he is startled by something loud or abrupt–he will extend his arms and legs and neck and then rapidly bring his arms together. He may even cry loudly.

Detailed explanation-2: -The Moro reflex is often called a startle reflex because it usually occurs when a baby is startled by a loud sound or movement. In response to the sound, the baby throws back his or her head, extends out the arms and legs, cries, then pulls the arms and legs back in.

Detailed explanation-3: -The Moro reflex is a normal reflex for an infant when he or she is startled or feels like they are falling. The infant will have a startled look and the arms will fling out sideways with the palms up and the thumbs flexed. Absence of the Moro reflex in newborn infants is abnormal and may indicate an injury or disease.

Detailed explanation-4: -Function. The Moro reflex may be a survival instinct to help the infant cling to its mother. If the infant lost its balance, the reflex caused the infant to embrace its mother and regain its hold on the mother’s body.

Detailed explanation-5: -The Babinski reflex occurs after the sole of the foot has been firmly stroked. The big toe then moves upward or toward the top surface of the foot. The other toes fan out. This reflex is normal in children up to 2 years old.
