Quizplus · Accepted Answer

The Moro reflex is commonly known as the startle reflex and is triggered by a sudden change in the environment, such as a loud noise. The infant's response includes arching their back, extending their limbs, and crying. The Palmar and Babinski reflexes involve different parts of the body and are not triggered by loud noises. The Premack principle is not a reflex but rather a theory about the use of preferred activities as a reinforcer for less-preferred activities.
