10名放射科医生在两种观看条件下观看了一系列10个正常和10个异常胸片：0.2秒闪光灯和无限观看时间。结果进行了比较的口头内容，诊断准确性和置信水平。考虑到不可能进行搜索，整体准确性令人惊讶地高（70%真阳性）。免费搜索的性能得到了预期的提高（97%的真阳性）。这些数据支持这一假设，即视觉搜索开始于建立内容的全球响应，检测与正常的总偏差，并组织随后的中央凹检查固定进行详细检查的歧义。总的搜索策略，然后由一个有序的序列散布的全球和检查固定。
Ten radiologists were shown a series of 10 normal and 10 abnormal chest films under two viewing conditions: a 0.2-second flash and unlimited viewing time. The results were compared in terms of verbal content, diagnostic accuracy, and level of confidence. The overall accuracy was surprisingly high (70% true positives) considering that no search was possible. Performance improved as expected with free search (97% true positives). These data support the hypothesis that visual search begins with a global response that establishes content, detects gross deviations from normal, and organizes subsequent foveal checking fixations to conduct a detailed examination of ambiguities. The total search strategy then consists of an ordered sequence of interspersed global and checking fixations.
