机械特征相似程度不同情况下类别联想对类别学习的影响

The Influence of Prior Knowledge on Category Learning under Different Degrees of Similar Rote Features

探讨机械特征相似程度不同情况下类别联想对类别学习的影响,共包括2个实验。被试是广州某大学70名学生。探讨类别内部机械特征相似程度不同情况下,由主题特征激活的类别联想对类别学习的影响。结果表明:(1)在类别内部项目机械特征相似程度高的情况下,一致主题特征激活的类别联想对类别学习起促进作用;不一致主题特征激活的类别联想没有对类别学习起阻碍作用。(2)在类别内部项目机械特征相似程度低的情况下,不一致主题特征激活的类别联想对类别学习起阻碍作用。

The study examined the effect of prior knowledge on category learning by 2 experiments. Participants in the research consisted of 70 college students. Experiment 1 used three animal categories as materials and Experiment 2 used two animal categories as materials, by which we can study how prior knowledge affects category learning under different degrees of similar rote features. The results showed that （1） When the rote features of category intra - items were rather similar, consistent prior knowledge would improve category learning; inconsistent prior knowledge would not hinder category learning. （2） When the rote features of the category intra-items were not so similar, inconsistent prior knowledge would hinder category learning.
