近年来，研究人员对偏离预期对认知处理，特别是注意力部署的影响越来越感兴趣。先前关于意外注意力关联的证据是基于注意力分配的间接测量。在这里，我们使用眼动追踪来直接观察一种新颖的颜色对其未经宣布的首次展示的影响，我们认为这是一个令人惊讶的情况。结果表明，眼球运动很快就能对新颖的颜色做出反应，并且在相当长的时间内目光都没有移开。这些结果是直接证据，表明偏离预期会导致注意力优先顺序出现偏差，并导致对偏离刺激的处理增强。
In recent years, researchers have become increasingly interested in the effects that deviations from expectations have on cognitive processing and, in particular, on the deployment of attention. Previous evidence for a surprise-attention link had been based on indirect measures of attention allocation. Here we used eyetracking to directly observe the impact of a novel color on its unannounced first presentation, which we regarded as a surprise condition. The results show that the novel color was quickly responded to with an eye movement, and that gaze was not turned away for a considerable amount of time. These results are direct evidence that deviations from expectations bias attentional priorities and lead to enhanced processing of the deviating stimulus.
