信号检测论在刑事诉讼认定证据中的应用

The Application of Signal Detection Theory in Criminal Proceedings

证据的认定是法律职业人涵摄证据材料特性与理解证据标准之后所作出的比较与匹配。将比较与匹配的心理过程凸显 出来有助于对证据认定的把握与理解。而信号检测论能满足这一要求并将辨别力的客观指标与主观变量分开来,还可以深入揭示判 断的影响因素及其对结果的预测。在一定程度上,运用信号检测论来解释认证过程比理想化地假设法官是理性的更切合实际。

Determination of evidence is the result of comparing and matching the features and criteria of evidence. To make the psychological process of comparing and matching prominent helps to grasp and understand the determination of evidence. While signal detection theory can meet this demand by distinguishing the objective factors from the subjective variables, it further reveals the factors influencing determination and predication of the result. To some extent, it is more practical to explain the process of determination by using signal detection theory than holding the ideal hypothesis of regarding the judge as reasonable.
