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.
Infant perception, process by which a human infant (age 0 to 12 months) gains awareness of and responds to external stimuli. At birth, infants possess functional sensory systems; vision is somewhat organized, and audition (hearing), olfaction (smell), and touch are fairly mature. However, infants lack perceptual knowledge, which must be gained through experience with the world around them.
