Annotation	Previous research has demonstrated that spatial attention is "depth aware": reaction times (RT) are greater for shifts in depth and two-dimensional (2-D) space than in 2-D space alone. 12 younger (age 18-25) and 12 older (age 62-85; mean 68.2 years) observers viewed stereoscopic displays in which one of four spatial locations was cued. Two of the locations were at a near depth location, and two at a far depth location. When the focus of visual attention was shifted to a new location in space (because of an invalid cue), the cost in RT for switching attention (measured as the difference between RT on valid cue and invalid cue trials) was greater when observers had to switch attention between different depth locations in 2-D space than for shifts in 2-D space alone. The effect was observed for both younger and older observers, suggesting that the ability to orient attention in a depth location is maintained with age. (RH).
