First, I suggest that you do an INDSCAL on the set of subject matrices
and find out the common matrix and the individual saliences for the

As to comparing the common subject space and the expert space, I recall

The result of this card sorting task is a symmetrical matrix with 56 rows and 56 columns. What I want to do is to correlate two matrices which represents an expert's categorisation of the cars and a subject's categorisation. Here I have the problem. I do not know how to do this. Can you help me in solving my problem? I am reasonably familiar with SPSS. Is it possible to do this with SPSS? Or do I need another program?
