The purpose of this paper is to suggest a technique of cluster analysis which is similar in aim to the Interactive Intercolumnar Correlation Analysis (IICA), though different in detail. Two methods are proposed for extracting a single bipolar factor (a "contrast compenent") directly from the initial similarities matrix. The advantages of this general approach are that: (a) It helps avoid certain misclassification problems inherent in IICA; (b) It is related in a straightforward way to conventional techniques o multidimensional scaling and therefore allows a unified treatment of dimensional and "typal" structures; and (c) It provides an interesting solution to the problem of relations among linear contrasts based on different subsets of the stimuli.
