Walk at Cornell University to investigate depth perception in human and animal species. This apparatus allowed them to experimentally adjust the optical and tactical stimuli associated with a simulated cliff while protecting the subjects from injury. The visual cliff consists of a sheet of Plexiglas that covers a cloth with a high-contrast checkerboard pattern. On one side the cloth is placed immediately beneath the Plexiglas, and on the other, it is dropped about 4 feet below. Since the Plexiglas supports the weight of the infant this is a visual cliff rather than a drop off. Using a visual cliff apparatus, Gibson and Walk examined possible perceptual differences at crawling age between human infants born preterm and human infants born at term without documented visual or motor impairments.

Artists were barred from work on the basis of their alleged membership in or sympathy with the Communist Party USA, or their refusal to assist investigations into the party's activities. Even during the period of its strictest enforcement, from the late 1940s through to the late 1950s, the blacklist was rarely made explicit or verifiable, but it directly damaged the careers of scores of individuals working in the film industry.
