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.
Created with CAST's UDL Book Builder. Robert Fantz made an important discovery in 1963 that advanced the ability of researchers to investigate infants' visual perception: Infants look at different things for different lengths of time. Fantz placed infants in a looking chamber, which had two visual displays on the ceiling above the infant's head.
