The term that does not belong is Babinski.
Imprinting, Moro, and Rooting are all reflexes that are present in newborn babies. Imprinting is a process by which newborn animals develop a strong attachment to their mother, usually the first moving object they see. The Moro reflex is a startle reflex that causes newborns to throw out their arms and legs and then pull them back in. The Rooting reflex is a reflexive turning of the head and opening of the mouth when the baby's cheek is stroked, helping the baby to locate the nipple for breastfeeding.
Babinski, on the other hand, is a reflex that is tested in adults to assess neurological function. It involves stroking the sole of the foot, causing the toes to fan out and the big toe to extend upward. In infants, this reflex is normal until about 12 months, but in adults, a positive Babinski sign can indicate a problem with the central nervous system. Therefore, Babinski does not belong with the other three reflexes which are specific to newborn babies.
