The Perception and Memory of Stereoscopic Depth Information in Naturalistic Scenes

Thomas A. Busey

Abstract

In three experiments with 432 participants, we examined the role of stereoscopic depth cues in the memory for objects and scenes. Stereoscopic depth cues are formed by disparities in the locations of objects in the images formed on the two eyes, and represent one possible cue to the depth that exists between objects. Using naturalistic pictures, we determined that stereo depth cues do persist in memory, as long as the observer is given several seconds to view the image and extract the depth relations from the scene. However, we did not find direct evidence that stereoscopic depth cues increase the rate of information extraction from scenes. Implications for theories of object recognition are explored.
