摘要: Family practice physicians read a case vignette describing patient with history of lung cancer, new transient neurological disturbance, and normal computerized tomographic (CT) scan the head. They then estimated probabilities two diagnoses: ischemic attack (TIA) brain tumor. Probability estimates TIA were lower if cancer was presented at end rather than beginning. This recency effect found for both more less experienced whether subjects prompted single end-of-sequence probability judgment or multiple step-by-step judgments after each piece information. These results are inconsistent Hogarth Einhorn's (1992) belief-adjustment model, which predicts condition but primacy condition.
