虽然以前的研究表明，深度知觉对视觉工作记忆（VWM）的影响不一致的结果，最近的一项研究表明，知觉接近的深度项目更好地记住比远项目时，相一致的差距和相对大小的线索相结合。在这项研究中，我们采用了类似的变化检测范式，研究饱和度和亮度，单独或与双目视差相结合，对VWM的影响。通过改变记忆项目的外观，我们的目的是操纵视觉显著性以及模拟空中透视线索，诱导深度知觉。我们发现，变化检测的准确性显着提高了更明亮，更饱和的项目，但不是单独的项目与更高的饱和度。此外，结合饱和度与全等视差线索显着提高记忆性能的感知更接近的项目比更远的项目。用饱和度消除差异提示消除了对较近项目的记忆益处。这些结果表明，饱和度和亮度可以调节深度对VWM的影响，视觉显著性和深度知觉可能通过共同的注意选择优先级机制影响VWM。
Although previous studies show inconsistent results regarding the effect of depth perception on visual working memory (VWM), a recent finding shows that perceptually closer-in-depth items are better remembered than farther items when combining the congruent disparity and relative size cues. In this study, we employed a similar change detection paradigm to investigate the effects of saturation and brightness, alone or in combination with binocular disparity, on VWM. By varying the appearance of the memory items, we aimed to manipulate the visual salience as well as to simulate the aerial perspective cue that induces depth perception. We found that the change detection accuracy was significantly improved for brighter and more saturated items, but not for items solely with higher saturation. Additionally, combining saturation with the congruent disparity cue significantly improved memory performance for perceptually closer items over farther items. Conflicting the disparity cue with saturation eliminated the memory benefit for the closer items. These results indicate that saturation and brightness could modulate the effect of depth on VWM, and both visual salience and depth perception affect VWM possibly through a common underlying mechanism of setting priority for attentional selection.
