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.
In fact, by 3-4 months infants have color perception similar to adults (Adams, 1995). At 1 week, the infant can discriminate the desaturated red from gray At 2 months, the infant can discriminate the desaturated blue from gray What do babies hear? Hearing is the most mature sense at birth. In fact, some sounds trigger reflexes even without conscious perception. The fetus most likely heard these sounds in the womb during last trimester Sudden sounds startle babies-making them cry, some rhythmic sounds, like a heartbeat/lullaby put a baby to sleep.
