In our experiment, we tested object depth effect on change blindness. We used CAVE virtual reality system for presenting stimuli for efficient simulation of 3D cues. Observers were exposed with arrays of 5 or 20 objects under flicker conditions typically inducing change blindness. They had to see which object is changing (disappearance, color change, or spatial shift) between interruptions. Objects could be presented either randomly in space, or arranged in global regular configuration. In 2D condition, sets of squares were presented in frontal plane before observers. In 3D condition, sets of binocularly simulated cubes were presented in frontal plane. Both reaction times and error rates were measured in the experiment. We found in the result that change detection performance benefits from 3D arrays as compared to 2D arrays. Although the magnitude of effect slightly varied depending on set size, change type, and regularity, the superiority of 3D over 2D objects was essentially the same for all conditions. This principal finding is in line with previously made observations that 3D cues play an important role in deployment of attention over visual scenes [Enns & Rensink, 1990, Psychological Science, 1, 326-323; Nakayama & Silverman, 1986, Nature, 320, 264-265].
