title: Role of faulty decision making in the satisfaction of search effect in chest radiography.
abstract: OBJECTIVE
  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.
  
  
  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.
  
  
  CONCLUSIONS
  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 faulty decision making.
