虽然任务驱动和刺激驱动的注意力偏差之间的经典区别乍一看似乎是二分法，但似乎还有第三类，它取决于主动表征和即将到来的刺激之间的对比或差异，可以被称为新颖性、惊喜或预测失败。对于之前差异-注意联系的论证，刺激驱动的成分（显着性）可能发挥了决定性作用。本研究的目的是评估显示器中的差异-注意联系，其中新颖的和熟悉的刺激等同于显着性。眼动追踪用于确定对新奇和熟悉的刺激的注视，作为注意力的代表。结果显示，新颖颜色的注意力优先，而熟悉颜色的优先级降低，这种颜色在第二次注视时明显存在，并跨越接下来的几次注视。另一方面，显着性并没有对显示中的项目进行优先排序。因此，结果强化了新颖性能够吸引并吸引注意力的观念。
While the classical distinction between task-driven and stimulus-driven biasing of attention appears to be a dichotomy at first sight, there seems to be a third category that depends on the contrast or discrepancy between active representations and the upcoming stimulus, and may be termed novelty, surprise, or prediction failure. For previous demonstrations of the discrepancy-attention link, stimulus-driven components (saliency) may have played a decisive role. The present study was conducted to evaluate the discrepancy-attention link in a display where novel and familiar stimuli are equated for saliency. Eye tracking was used to determine fixations on novel and familiar stimuli as a proxy for attention. Results show a prioritization of attention by the novel color, and a deprioritization of the familiar color, which is clearly present at the second fixation, and spans over the next couple of fixations. Saliency, on the other hand, did not prioritize items in the display. The results thus reinforce the notion that novelty captures and binds attention.
