Final answer:
Newborns have limited vision but can see human faces and objects in front of them. They have a preference for faces and are drawn to shiny objects, colors, and patterns. Their hearing is well developed and they respond more readily to female voices, especially their mother's voice. They also have a strong sense of smell and can distinguish their own mother's scent.
Step-by-step explanation:
Newborn infants' vision is not fully developed. They are only able to focus on objects that are directly in front of their face and about 46 cm away. However, this is sufficient for the baby to see the mother's face, as well as the areola and nipple. As the baby grows, their color perception and depth perception will improve.
On the other hand, their sense of hearing is well developed at birth. They usually respond more readily to female voices, with a preference for the mother's voice. Sounds that the baby heard before birth, such as the parent's breathing and heartbeat, are also comforting to the newborn.
Newborns also have a strong sense of smell and can distinguish the smell of their own mother from others. They have a preference for looking at human faces above all else and are drawn to shiny objects, sharp contrasting colors, and complex patterns.
