三个实验考察了在标准概念习得任务中，知识如何影响概念的形成和表征。主要的比较是在具有无意义特征的任意概念、具有来自不同领域的有意义特征的有意义概念以及具有通过共同知识相互联系的有意义特征的综合概念之间进行比较。实验一发现，整合概念的学习效果更好，但作为特征意义函数的差异不大。实验二表明，整合的被试正在学习形成一种基于知识的图式作为其概念表征，因为他们没有区分频率不同的特征的典型性。实验3引入了一个类别，其特征来自同一领域，但在其他方面没有关联。这个概念和有意义的概念一样难以学习和使用。这些比较有助于明确知识影响和不影响概念形成的方式。
Three experiments investigated how knowledge influences concept formation and representation in a standard concept acquisition task. The primary comparison was among arbitrary concepts, which had meaningless features; meaningful concepts, which had meaningful features from different domains; and integrated concepts, which had meaningful features interconnected by common knowledge. Experiment 1 found that learning was superior for the integrated concepts but that there was little difference as a function of feature meaningfulness. Experiment 2 suggested that the integrated Ss were learning to form a knowledge-based schema as their concept representation because they did not distinguish the typicality of features that differed in frequency. Experiment 3 introduced a category whose features were from the same domain but were not otherwise related. This concept was as difficult to learn and use as the meaningful concepts were. These comparisons help specify the ways in which knowledge does and does not influence concept formation.
