摘要
探讨在多类别情境中新项目与类别成员的关系对特征推理的影响。共包括两个实验,被试是212名大一学生。实验1与实验2分别探讨类别特征的竞争性与相似性对特征推理的影响。结果表明:无论当非靶类别中目标与关键特征维度是否结合及是否预先归类时,类别特征的相似性与竞争性影响特征推理,验证了类别学习的特征概率模型。
The present study explored the influence of relations between new items and category members on feature induction through the paradigm of multiple categories. 212 freshmen participateds in two experiments, which investigated the influence of rivalrousness and similarity of category features respectively. The results showed that the rivalrousness and similarity of category features affected feature predictions, no matter whether the objectives and pivotal features of non-target categories were combined and no matter whether the subjects were asked to classify items in advance or not, a finding which validated the Features＇ Probability Model of Category Learning.
