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.
Babies this age can focus on shapes that are close by, but see distant objects as blurry because they are nearsighted. As babies grow, eyesight improves. By the end of 3 months, they can follow a moving object, are more interested in shapes and patterns, and can spot familiar faces, even at a distance. Human faces are one of their favorite things to look at, especially their own or a parent's face.
