...parents are facing the issue of whether or not their children are ready for the big step into the classroom. Before entering kindergarten children need to develop their perceptual skill (depth perception). As humans we need depth perception for detection, discrimination, and identification of objects. Depth perception is a difficult topic to access due to the fact that the world is three dimensional and human visions are two dimensional. When transmitted to the brain, an image on the retina is not a picture; rather it is a pattern of nerve impulses, aroused by a light pattern that terminates in the visual area of the cerebral cortex. Through some activity of the occipital lobes of the cerebral cortex, human beings apparently perceive the external world in a three-dimensional manner that is correlated with the retinal-image pattern in some orderly manner.
Psychologists are particularly interested in the cues which enable people to perceive depth and distance. Stimulus patterns for arousing a depth experience occur when individuals are given specific cues. The cues may be monocular, effective when using one eye as well as two, or binocular, requiring the usage of both eyes. The cues may also be psychological, depending only on the visual image, or physiological, originating from the structure and movement of the eyes.
In this paper I will explain perceptual development and how it relates to animals, infants, and blind infants. Infancy is the period of life in which development occurs most rapidly. Development occurs in a variety of different ways and has been categorized with the study of infancy into physical, motor, and perceptual development. Each of these forms of development occurs simultaneously and progress in each facilitates the progress of the other. There are many studies I will assess to further explain how they contribute to explaining the...
