依据和目标：我们测试是否有临床信息将提高知觉或简单的decisionmaking.METHODS：64儿科胸部和腹部X光片，其中一半有异常，提出了9个放射科医生在两个条件之一。在一种情况下，在检查前为阳性和匹配的阴性病例提供与阳性病例实际存在的异常一致的病史。在第二种情况下，只有在检查完成且X光照片不再可用之后才提供该信息。由于详细的视觉记忆是短暂的，当检查后提供历史时，图像信息不再可用。一个控制条件测量检测无history.Results：检测显着更好的历史检查前提供。检测没有不同的检查和检查后提供的历史没有history.CONCLUSION：历史条件之间的唯一区别是在历史是否影响感知，历史影响决策在这两种条件。临床病史影响解读X光片的感知，而不仅仅是决策。
RATIONALE AND OBJECTIVES: We tested whether having clinical information would improve perception or simply decision making.METHODS: Sixty-four pediatric chest and abdominal radiographs, half of which had abnormalities, were presented to nine radiologists under one of two conditions. In one condition, history consistent with abnormalities actually present for positive cases was provided for positive and matched negative cases before inspection. In a second condition, this information was provided only after inspection was completed and the radiograph was no longer available. Because detailed visual memory is short-lived, the image information was no longer available when the history was provided after inspection. A control condition measured detection without history.RESULTS: Detection was significantly better with history provided before inspection. Detection did not differ for history provided after inspection and inspection without history.CONCLUSION: The only difference between conditions with history was in whether history influenced perception; history affected decision making in both conditions. Clinical history affected perception in interpreting radiographs, not simply decision making.
