Osgood, Suci, and Tannenbaum in their work with the semantic differential developed a technique with which data from an individual could be represented by a three-dimensional model. The model is derived from distance scores based upon profile ratings of concepts such as mother or self, on subscales such as kind-cruel, weak-strong, etc. Osgood identified three main dimensions for meaning (and models)--evaluation, potency, and activity--which are assumed to be orthogonal. The models are fascinating and useful but involve a great deal of work. This paper describes procedures which yield a good approximate model in 3-5 hours; less time is required with experience. Further, the approximate model can serve as the basis to build the exact model in less time than would have been possible otherwise. The improvements include computer cards which can be used for doing the ratings, FORTRAN computer programs, a special apparatus for use as a frame for building the model, directions, and a template for drawing the model in perspective. Several hundred undergraduate students have completed the models and a few clinical cases have been evaluated. Appendices include administration instructions; sample computer cards, programs, and outputs; and plans for building the model. (Author/CTM)
