An auditory stimulus, cheeping, was used in an attempt to establish a preference in 40 DeKalb No. 131 and 40 Ghostley chicks for the deep side of a visual cliff. Approximately 80% of all responses were made to the shallow side. The cheeping, however, did have a differential effect on the number of deep responses by the two strains; in one strain a significantly greater number of deep responses was made when the deep side of the cliff faced in the direction of the noise, while in the other strain this difference was not observed. Some theoretical aspects of depth perception are discussed.
