title: Shifting visual attention in stereographic displays: a time course analysis.
abstract: According to a growing number of studies, the stereographic presentation of three-dimensional information improves overall performance relative to displays with only monocular depth cues. Based on studies using real-world, three-dimensional stimuli, however, the efficiency (i.e., speed) of shifting attention between objects located at different depths is impaired relative to that of attention shifts between objects located at the same depth. In the present study we tested whether similar impairments occur when attention is shifted in stereographic space. We compared the time course of attention shifts across and within depth planes using a spatial cuing task. Contrary to the results from studies of real-world stimuli, we found no difference between the time course of within-plane and across-plane attention shifts.
