将描述用于匹配心理刺激的物理和感知空间的算法。每个刺激类别的目标点必须在多维感知空间中选择。物理空间由多维测量空间组成，其中对大量受试者的每个刺激进行测量。确定从测量空间到感知空间的线性变换，使得目标点和变换的测量点之间的均方距离最小化。不要求测量空间和感知空间的维数相同。因此，该算法可用于以更少的维度重新定义测量空间，从而最大化与预定义刺激类别的对应关系。该过程已使用 /hVd/ 上下文中说出的元音、测量参数的六个主要成分以及三维感知空间进行了测试。感知空间中的目标位置是......
An algorithm for matching physical and perceptual spaces for psychological stimuli will be described. Target points for each stimulus class must be chosen in a multidimensional perceptual space. The physical space consists of a multidimensional measurement space, in which measurements are made of each stimulus for a large number of subjects. A linear transformation from the measurement space to the perceptual space is determined such that the mean square distance between target points and transformed measurement points is minimized. There is no requirement that the dimensionality of the measurement and perceptual spaces be the same. Thus the algorithm can be used to redefine the measurement space with fewer dimensions such that the correspondence with predefined stimulus categories is maximized. This procedure has been tested using vowels spoken in an /hVd/ context, six principal components for measurement parameters, and a three‐dimensional perceptual space. Target positions in the perceptual space were ...
