研究了概念结构演化和原型抽象的几何模型。多维尺度被用来评估一个概念空间包含多个类别从一个相对未分化的状态，反映了必要的类别学习的转变。三个实验，每个使用20名大学生，包括一个共同的评级阶段，涉及21个刺激（原型加6个样本，从每个3类），与3个实验区分的抽象量提供了3个类别的事先操纵。在3个实验中，整个概念空间的类别结构的程度得到加强，类别结构的变化是最大的那些类别定义的许多模式在学习过程中。此外，原型在每个类别中占据了理想的位置，类别内距离与类别间距离的比值对于原型来说是最小的。有人建议，使用多维缩放作为一种辅助类别抽象的效用是，可以跟踪整个概念空间的结构变化，作为变量的基础类别抽象系统地操纵。(22参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Investigated a geometric model for the evolution of conceptual structure and prototype abstraction. Multidimensional scaling was used to assess the transformation of a conceptual space containing multiple categories from a relatively undifferentiated state to one that reflected the requisite category learning. Three experiments, each using 20 undergraduates, included a common rating phase involving 21 stimuli (prototype plus 6 exemplars from each of 3 categories), with the 3 experiments distinguished by prior manipulations of the amount of abstraction afforded the 3 categories. Across the 3 experiments, the degree of category structure for the entire conceptual space was enhanced, and the change in category structure was greatest for those categories defined by numerous patterns during learning. In addition, the prototype occupied an ideal location in each category in that the ratio of within-to between-categories distance was smallest for the prototype. It is suggested that the utility of using multidimensional scaling as an adjunct to category abstraction is that the changing structure of an entire conceptual space may be tracked, as variables underlying category abstraction are systematically manipulated.(22 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
