原理和目的，作者进行了这项研究，以确定是否有缺陷的模式识别或有缺陷的决策是更多的责任满意度的搜索（SOS）的胸部X线摄影，材料和方法的错误。由20名观察员阅读了58张胸片，其中一半表现出不同的本地异常。X线片读取两次，一次添加模拟肺结节，一次未添加模拟肺结节。观察员口头描述了他们的注意力焦点，指出了他们在检查X光片时考虑的可疑特征和区域。观察者还提供了一个单独的帐户的异常，他们将包括在一个放射学报告。当作者只考虑那些没有提到模拟结节的报告时，他们发现在含有结节的病例中，适当的受试者工作特征（ROC）曲线下的面积没有减少。然而，通过分析在一种情况下而不是另一种情况下遗漏了天然异常的事件，证明了较小的SOS效应。口头协议表明SOS错误主要是由识别失败而不是错误的决策。描述他们的注意力焦点可能会促使观察者以更谨慎、更系统的方式检查X光片，从而减少SOS效应。有缺陷的模式识别比故障引起更多的剩余SOS错误！，决策。
Rationale and Objectives, The authors performed this study to determine whether defective pattern recognition or defective decision making is more to blame for satisfaction of search (SOS) errors in chest radiography,Materials and Methods. Fifty-eight chest radiographs-half of which demonstrated diverse, native abnormalities-were read by 20 observers. The radiographs were read twice, once with and once without the addition of a simulated pulmonary nodule. Observers provided a verbal account of their focus of attention, indicating suspicious features and regions considered during their inspection of the radiograph. Observers also provided a separate account of the abnormalities they would include in a radiologic report.Results. When the authors considered only those reports that did not refer to the simulated nodules, they found no reduction in the area under the proper receiver operating characteristic (ROC) curves in cases that contained nodules. A smaller SOS effect, however, was demonstrated with analysis of events in which the native abnormality was missed in one condition but not the other. Verbal protocols suggested that the SOS errors were mainly caused by recognition failure rather than faulty decision making.Conclusion. Describing their focus of attention may have prompted observers to inspect the radiographs in a more deliberate, systematic way, thus reducing the SOS effect. More residual SOS errors were caused by defective pattern recognition than by fault!, decision making.
