The described response of arching the back, flailing arms outward, and then quickly bringing them together in an embrace is characteristic of the Moro reflex. This reflex is triggered by a sudden change in stimulation, such as a loud noise or sudden movement. The Babkin, rooting, and Babinski reflexes are not associated with this particular response.
