Answer #1
  • Sensory systems need two kinds input to develop: genetic instructions and stimulation from the environment. All of the senses except for vision are stimulated in the womb. The sense of touch is the first sensory system to develop in the womb and is likely the most mature at birth.
  • The sense of taste and smell also develop in the womb and vision develops later because babies are born without true depth perception, and color vision is very limited. Experiments also show that newborns recognize the smell of amniotic fluid and they like the scent of breast milk. Since mother's milk is sweet,and thats the first food babies taste therefore it develops much faster than other senses. Babies cannot taste salt until they are 4months old but sweetness they can because of first taste they get of the mother's milk.
