本研究通过四个实验考察了注意定势是否影响视觉瞬间(起始点和偏移点)捕捉注意的能力。在实验中，对身份定义的目标进行了视觉搜索。在前三个实验中，目标显示要么完全开始，要么通过抵消伪装线段来显示字母。在目标显示之前，在一个潜在的目标位置处有一个非信息性的提示，要么是开始，要么是偏移。与目标显示器具有相同瞬变特征的提示吸引了人们的注意。缺乏可预测的目标瞬变导致所有形式的瞬变都会引起注意力捕捉。在没有偏移量或开始的情况下，最终的亮度变化实验显示，当亮度变化较大时，注意力会被捕获。结果表明，注意力设置可以广泛或狭隘地调整，以检测亮度的变化。
Four experiments were conducted to examine whether attentional set affects the ability of visual transients (onsets and offsets) to capture attention. In the experiments, visual search for an identity-defined target was conducted. In the first 3 experiments, the target display either onset entirely or was revealed by offsetting camouflaging line segments to reveal letters. Prior to the target display, there was a noninformative cue, either an onset or an offset, at one of the potential target locations. Cues that shared the same transient feature as the target display captured attention. The lack of predictable target transients led to attentional capture by all forms of transients. The final experiments with luminance changes without offsets or onsets showed attentional capture when the luminance changes were large. The results suggest that attentional set can be broadly or narrowly tuned to detect changes in luminance.
