| 摘 要： | 作者用以大学生被试的一个实验考察归类不确定情景下样例的代表典型性对特征归纳预测的可能影响。实验结果表明,预测特征相对于目标特征的综合条件概率影响特征归纳预测,而样例的代表典型性并不影响特征归纳预测,没有出现样例的代表典型性效应。预测特征综合条件概率策略能预测解释这种结果。

| Abstract: | An experiment with participants of college students was done to examine the possible influence of representative typicality of examples on feature induction in uncertain categorization in the concentrative presentation of samples of category members.It is found that the overall conditional probability of a prediction feature relative to a target feature influences feature induction,whereas the representative typicality of examples does not influence feature induction.The overall conditional probability model of prediction features can explain the results. |

| Keywords: | categorization feature induction examples representative typicality the overall conditional probability |
