It has been repeatedly demonstrated that when performing a visual search task, items can pop out of a display such that they are identified rapidly, independent of the number of distractors present. It has been less clear whether this type of pop-out is limited to static displays (e.g., images) or whether it can also occur in scenes containing movement, more akin to how we experience the real world. Recently, Jardine and Moore (Journal of Experimental Psychology: Human Perception and Performance, 42, 617–630, 2016) examined whether pop-out also occurs in displays consisting of dynamic motion – wherein items in the display rotated continuously until a critical frame that would elicit pop-out under static presentation conditions – and found that search was greatly impaired. It remains unclear, however, whether such impairment is exerted equivalently across all types of dynamic motions or if it is specific to orientation. In the present study, we replicate the original Jardine and Moore (Journal of Experimental Psychology: Human Perception and Performance, 42, 617–630, 2016) finding and extend this examination to another dimension – color change. We also explore whether search efficiency can be improved with dynamic context if aspects of the display become predictable. The results suggest that not all types of dynamic change impair search performance. Specifically, oddball color targets continue to pop out even when the items in the display are dynamic. Interestingly, adding predictable context did not aid search accuracy as expected, rather resulting in poorer performance. Taken together, the findings suggest that the influence of dynamic context on search performance is not absolute.

已经反复证明，当执行视觉搜索任务时，项目可以从显示器弹出，从而可以迅速识别它们，而与存在的干扰物数量无关。目前还不清楚这种弹出式窗口是否限于静态显示（例如图像），或者是否也可以出现在包含运动的场景中，更类似于我们对现实世界的体验。最近，《怡和（Jardine and Moore）》（实验心理学杂志：人类的感知和表现，42，617–630，2016）检查了弹出动作是否也出现在由动态运动组成的显示器中-显示器中的项目不断旋转，直到在静态展示条件下会引起弹出的关键帧为止-并且发现搜索受到了极大损害。然而，尚不清楚这种损伤是否在所有类型的动态运动中均等地施加，或者是否特定于定向。在本研究中，我们复制了最初的《渣甸和摩尔》（《实验心理学杂志：人类的感知与表现》，第42页，617 – 630，2016年）找到并扩展到另一个维度-颜色变化。我们还探讨了如果显示的各方面变得可预测，则动态上下文能否提高搜索效率。结果表明，并非所有类型的动态变化都会削弱搜索性能。特别是，即使显示中的项目是动态的，奇怪的颜色目标也会继续弹出。有趣的是，添加可预测的上下文并不能像预期的那样帮助提高搜索准确性，反而会导致性能下降。两者合计，发现表明动态上下文对搜索性能的影响不是绝对的。
