With a pair of oppositely valenced stimuli, rating the first one sometimes leads to a more extreme evaluation for the second (e.g., if the second is negatively valenced, rating the first stimulus would lead to a more negative rating for the second). We considered an evaluation bias in the case of clinical diagnosis relating to eating disorders. A population sample which included experienced clinical psychologists and psychiatrists showed partial evidence of an evaluation bias, when judging descriptions of individuals designed to be consistent with eating disorders or not. Quantum probability theory, the probability rules from quantum mechanics without any of the physics, is particularly well-suited to modeling the evaluation bias (and constructive influences generally), because a measurement (or judgment) can change the state of the system. We applied a previous quantum model to the present result, an extension of the model embodying noisy processes, and belief adjustment model. We discuss how model fits inform an examination of rationality in the observed behavior.

临床判断中的建设性偏见

对于一对相反价的刺激，评价第一个刺激有时会导致对第二个刺激的更极端的评价（例如，如果第二个是负价，评价第一个刺激会导致对第二个刺激更负面的评价）。在与饮食失调有关的临床诊断中，我们考虑了评估偏差。包括经验丰富的临床心理学家和精神病学家在内的人群样本在判断是否符合饮食失调的个体描述时显示出部分评估偏倚证据。量子概率论，即没有任何物理学的量子力学的概率规则，特别适合模拟评估偏差（以及一般的建设性影响），因为测量（或判断）可以改变系统的状态。我们将先前的量子模型应用于目前的结果、体现噪声过程的模型的扩展和信念调整模型。我们讨论了模型拟合如何通知对观察到的行为的合理性的检查。
