Types of Neuropathy. Peripheral neuropathy is a disorder of the peripheral nervous system, which includes the sensory and autonomic nerves that connect the spinal cord and muscles, skin and internal organs. It usually affects the limbs, causing numbness, prickling and pain.
Gibson and Walk (1960) hypothesized that depth perception is inherent as opposed to a learned process. To test this, they placed 36 infants, 6 to 14 months of age, on the shallow side of the visual cliff apparatus.
Depth perception is very complex, but it is not literally age-related. Depth perception is most helpful for tasks performed within 30 inches of our eyes. The two major causes of altered depth perception are reduced vision in one or both eyes, and secondly, eye muscle weakness. If the loss of depth perception involves literal double vision, neurological disorders must be considered.
