(2) Developmental psychology is a field of psychology that looks at how people grow. One thing this field looks at is infants and their growth. For example, when a baby is born, it has very poor vision. The baby cannot make out detail, only large shapes. Also, infants can only make out differences in bright red balls. Vision improves as infants get older.
(3) Infant’s vision is almost the same as adults. They call tell not only the rough shape of objects, but also extreme details. For example, they can tell the difference between bright red colors and light blue colors.
(4) Researchers should train infants in their vision ability. After six-month training, infants can develop an important ability they needed when they grow up. The training programs including processes like shape recognition as well as color training. Therefore, vision improves greatly as infants grow up.
