这些实验使用空间探针来测量在搜索八个字母阵列中的目标字母时，空间注意力如何在整个视野中分配。主要研究结果有三：注意强度是根据目标和干扰物之间的混淆程度灵活调整的。目标附近的干扰物位置比远离目标的位置受到更多的抑制，这表明附近的干扰物对目标识别的干扰更大。尽管事实上，一致的做法提高搜索速度，它并没有减少空间注意力的强度在这项任务中。
These experiments used spatial probes to measure how spatial attention is allocated across the visual field during search for a target letter in an eight-letter array. There were three main findings: Attentional strength is flexibly adjusted according to the confusability between target and distractors. Distractor locations near the target receive more inhibition than those farther from the target, indicating that the nearby distractors interfere more with target identification. Despite the fact that consistent practice improves search rate, it does not diminish the strength of spatial attention in this task.
