A later experiment with kittens raised in the dark and then placed on the visual cliff showed that depth perception was not innate in all species as the kittens would walk on either side of the visual cliff. After six days of being in the light, the kittens would avoid the deep side of the visual cliff (Rodkey, 2015).
Together they proposed perceptual learning as a process of seeing the differences in the perceptual field around an individual. An early example of this is the classic research study done by Eleanor Gibson and R. D. Walk, the visual cliff experiment. In this experiment an infant that was new to crawling was found to be sensitive to depth of an ...
The major components of the visual system can be broken up into visual acuity, depth perception, color sensitivity, and light sensitivity. By providing a better understanding of the visual system, future medical treatments for infant and pediatric ophthalmology can be established. By additionally creating a timeline on visual perception ...
A combination of 1) wanting to get the most use out of the rats along with, 2) inspiration from both Eleanor's experience with the goats and a similar previous experiment done by Lashley & Russell in 1934, [13] produced the idea of studying depth perception with the visual cliff. [12] Walk & Gibson studied visual depth perception in rats ...
In one experiment, done in 1959, they inserted a microelectrode into the primary visual cortex of an anesthetized cat. They then projected patterns of light and dark on a screen in front of the cat. They found that some neurons fired rapidly when presented with lines at one angle, while others responded best to another angle. Some of these ...

A related phenomenon is the visual system's capacity to calculate time-to-contact (TTC) of an approaching object from the rate of optical expansion – a useful ability in contexts ranging from driving a car to playing a ball game. However, the calculation of TTC is, strictly speaking, a perception of velocity rather than depth.
A water cliff is a visual cliff with water in the deep end of the apparatus, and can measure an infant's potential perception of danger, as well as sensitivity to water. [6] The results indicating that crawling experience was a greater indicator of avoidance align with the environmentalism theory in that infants learn through experiences with ...
