Abstract : A combination is achieved of two lines of psychometric interest: multidimensional scaling and factor analysis. This is accomplished with the use of three-mode factor analysis of scalar product matrices, one for each subject. Two of the modes are the group of objects scaled and the third mode is the sample of subjects. Results are an object space, a person space and a system for changing weights given to dimensions and of angles between dimensions in the object space for individuals located at different places in the person space. The development is illustrated with data from an adjective similarity study. (Author)
