为获得汉语辅音的知觉特征,我们采用了拟合的最佳品质因素的多维标度,对汉语辅音的知觉混淆矩阵进行分析。其结果是求得了作为拟合优度标准的归一化残差值(Stress)随维数增加而减少的函数关系,由此得到的结论是表征汉语辅音的知觉空间不得少于三维。从所求得的有代表性的三维结构中可以看出:第一维代表清音-浊音;第二维代表送气-不送气;第三维代表发音部位,因此可以认为清-浊、送气-不送气和发音部位是汉语最基本的区别特征。我们将21个汉语辅音的知觉特征形象化地表示于一个多维的心理空间,有助于对知觉特征的进一步研究,并且为汉语辅音的科学分类提供心理、物理实验的支持。本文简单介绍多维标度方法,讨论利用台式电子计算机进行多维标度的程序设计、空白记录的处理和初始结构的设定问题,并列举典型的分析结果。这些结果将在另一篇关于汉语辅音知觉特征的文章中作详细讨论。
To obtain the consonant features of Chinese consonants, we use a multidimensional scaling of the best fit quality factor to analyze the perceptual confusion matrix of Chinese consonants. As a result, the normalized residual (Stress) as the criterion for goodness of fit is reduced as the number of dimensions increases. The conclusion is that the perceived space for characterizing Chinese consonants should be no less than three dimensions. As can be seen from the representative three-dimensional structure obtained: the first dimension represents voiceless - dullness; the second dimension on behalf of the air - not aspirated; the third dimension on behalf of the articulation site, it can be considered clear - turbidity, aspirated - not aspirated And the pronunciation part is the most basic difference between Chinese characteristics. We visualize the conspicuous features of 21 Chinese consonants in a multidimensional psychological space, facilitate the further study of perceptual characteristics, and provide psychological and physical experimental support for the scientific classification of Chinese consonants. In this paper, we briefly introduce the multidimensional scaling method, discussing the programming of multi-dimensional scaling by using a desktop computer, dealing with the blank records and setting up the initial structure, and enumerating the typical analysis results. These results will be discussed in detail in another article on the perceptual characteristics of Chinese consonants.
