样例呈现方式对概念训练类别表征的影响

以往研究发现训练形式会影响类别学习的表征方式。实验采用学习-迁移范式,探究概念训练中样例的呈现方式对类别表征的影响。实验中被试通过不同呈现方式来学习类别知识,在学习3个block之后对其进行测验。实验结果表明:(1)学习单样例和同一类别比较学习的被试在测验阶段的成绩与学习阶段之间没有差异;(2)学习不同类别比较学习的被试在测验阶段的成绩大幅度下降。因此得出结论,在概念训练中,不同类别比较学习导致被试形成类别间信息的表征。

The Influence of Item-Presenting Mode to Concept Training in Category Representation

Previous studies have found that training methodology will affect the representation of category learning.This experiment adopts the learning-transfer paradigm to study the influence of the presentation of the sample on the category representation in the concept training.The participants study category knowledge through learning different item-presenting mode in the experiment.After studying 3 blocks,they will accept the test.Experimental results show:(1)there is no difference between the result of test phase and the learning phase of the participants who study single item and the participants who study comparison learning of same-category item-pairs.(2)The test results of the participants who studied comparison learning of different-category item-pairs declined significantly in the test phase.Therefore,it is concluded that in conceptual training,comparison learning of different-category item-pairs will lead to the formation of between-category representation to the participants.
