Final answer:
Newborn infants prefer their mother's voice, recognize her scent, and turn towards her smell.
Step-by-step explanation:
Newborn infants have a preference for their mother's voice over other women's voices. Research has shown that newborns listen to their mother's voice longer than other sounds, and they show stronger sucking reflex when they hear their mother's voice. Additionally, newborns can recognize their mother's scent and turn towards the smell of their own mother.
