Visual perception development

The development of visual perception changes through the caurse of life time from birth through adulthood. Sight is produced by taking "stimulation in the form of light and converting it to electrochemical signals to the brain." Most of the development of visual perception takes place in infants and then declines in old age.

In Young infants is when visual perception begins to grow and develop. A new born can see changes in brightness and is able to see the world in color. Earlier diserves believed new borns could only see in black and white. At four months babies seem to discriminate between colors where as a new born can see color but unable to discrimninate between differences. Babies prefer objects with a pattern as opposed to a blank object. Taking this knowledge observes came up with a way of mearuring babies eyesight by presenting a pair of disks with a pattern and gradually increasing the fine-grained stip disk to find the point where the baby cannot tell the difference between a pattern and a blank disk. The observes found that newborns can have as poor of an eyesight as 20/600 wich means object that adults can see 600 feet away a newborn can see only 20 feet away. Objects to


infants are blurry that are more than eight inches from their face unless the object is bold and has an extreme light/dark contrast (Singelman 145). Altgought babies are unable to discrminate between color, they can discriminate between different patterns. Robert Fantz, during the ealry 1960's, found that babies less than two days old can differenciate visual forms. Babies being attracted to visual forms show to take great interenst in the patterns in the human face. Young infants are also attracted to moving objects. Even though infants tracking of moving objects has not matured yet and moving things can be lost unless its moving very slow a moving object is more apt to gain a babies attention than a stationary object. Infants prefer moderate complex patterns than high complex patterns where they are unable to make out all the detail (Singlman 146). Another important factor in visual perception is depth perception. Depth perception involves perceiving depth and knowing when objects are near or far away. Infants have some abilitly to interpet special cues involving nearby objecs. They are able to recognixe objects of the same size at different distances. In a tudy of visual cliff, babies of croling age were tested to see if they could sence the drop off. Twenty seven out of thirtysix would cross the shallow end, while only three out of the thirty six would cross the deep end to reach Mommy. To test infants too young to crawlthey were lowered in to the shallow end and then into the deep end. To test fear they heart rte was monitored. It showed that a babies heart rate was slower when low
