Babies can see clearly at the age of 4 weeks, the baby’s eyes begin to learn to detect in a single location by blinking. Because the baby’s eyes can not clearly distinguish the objects, at the age of 6 months babies start to learn to distinguish the human face and animal faces.
Newborns, generally attracted to faces he met. Babies can see all things in a round shape that has two eyes and a mouth in the right place. Preference is more apparent in infants, and infants can process the different faces of other objects.
The best sensor of infant the visual system is a motion sensor. A motion sensor on the infant the visual system, the sensor is developed early, quoted from CNNHealth, Wednesday, September 21, 2011.
Age of the baby entering the fourth week, the baby already knows how to blink in one location is almost as good as adults. Entered the seventh week of age, the baby can a already distinguish the direction of motion and entered the age of 20 weeks, the development of the baby is growing fast.
Age of the baby entering the 4 to 5 months, babies begin to learn the maturation of the fusiform face area, an area specialized for processing the temporally contexts face. This specialization allows the adult brain may be able to beat the best programs in the computer world in detecting subtle differences between faces.
In the fusiform face area began activated by faces that are often encountered when entering the the baby age of 2 months. The visual experience affects the development of the face that begins in infancy.
Age of your baby entering the 6 months, the baby have started to differentiate between humans and animals. When old baby 9 months, would be more perfect to identify people’s faces and animals lost the ability to recognize faces.
Vision in infants would be better in distinguishing the faces of their own racial group than in other racial groups. This may be because most infants have more visual experience with their own racial group than other races. This developmental process involves a process of refinement of synaptic connections by experience to improve perceptions of local environmental characteristics.
Vision in infants have experience in processing motion the most susceptible to interference. Aspects of motion processing may be delayed in some developmental disorders, including dyslexia, autism, fragile-X syndrome and Williams syndrome.
But on the contrary, children who experience vision problems such as cataracts from birth will have a different development with a normal baby. This condition causes the visual system in infants can not grow like normal conditions. Baby old 9 months, who was born with cataracts have not been able to look like other normal the baby.
In the baby experienced visual experience, to support the development of visual acuity in the baby is increasing. But at the age of 3 to 8 months of the first the baby has a sharpness on sight approximately 3 times worse than the baby at the age of 5 years of a normal.
The global development is influenced by the cataracts is only in the first 3 months of life. So for the development of visual acuity in infants, will still run well. But for this extraordinary case the role of parents is necessary here and need to be careful, that usually require extra attention.
