在校对中，注意力必须分配到整个文本，以检测句子上下文中的异常单词。由于专业校对员对空间注意力分配具有上级控制能力，因此假设他们的技能可以推广到某些其他任务。为了验证这一假设，专业校对进行了比较，新手使用变化盲视和视觉搜索任务。变化盲视任务的结果表明，校对检测到更多的目标（非预先指定的场景变化）比新手分配注意到整个场景。相比之下，新手的注意力往往被吸引到视觉场景的上部。结果的视觉搜索任务，其中包括计数预先指定的目标，校对和新手之间没有表现差异。这意味着校对员具有高度发达的空间注意力分配能力，通常适用于检测目标和干扰物都没有预先指定的注意力要求搜索情况。
In proofreading, attention must be allocated to the entire text in order to detect anomalous words within the sentence context. Because professional proofreaders have superior control of spatial attentional allocation, it is hypothesized that their skill may generalize to certain other tasks. To test this hypothesis, professional proofreaders were compared to novices using change blindness and visual search tasks. Results of the change blindness task showed that proofreaders detected more targets (non-predesignated scene changes) than novices by allocating attention to the entire scene. By contrast, novices' attention tended to be attracted to the upper part of visual scenes. Results of the visual search task, which involved counting predesignated targets, showed no performance differences between proofreaders and novices. This implies that proofreaders have a highly developed ability for spatial attentional allocation that is generally applicable to attentional demanding search situations where both detection targets and distractors are not predesignated.
