The present paper shows the usefulness of various methods of three-mode factor analysis for the cross-cultural comparisons of value concepts. Data were obtained from 300 German and 300 American students, using theindividual and Organizational Values SYMLOG rating form. The comparative structural analyses of the saqtples made it apparent that the SYMLOG rating forms .· used did not yield the expectect correspondence to' the theoretical three-dimensional value space. The reasons and corisequenc'es of these' findings for further studies in this field are discussed. The methodological approach outlined in this paper can supplement the criteria formulated Bales et aL (1987) for adaptation of SYMLOG rating items to particular populations and cultural contexts and it provides more adequate procedures for data analysis.

A discrete, categorical model is presented for three-mode (conditions by objects by attributes) data arrays with binary entries xijk 2 f0; 1g. Basically, the model attempts a simultaneous classification of the entities or elements of the three modes in a number of common clusters. Clusters are denied by three-mode submatrices of maximum size with entries xijk = 1. In performing a discrete representation of the data structure, the model may be classified as a non-hierarchical clustering procedure. It involves a reorganization of the data array such that the clustering solution is interpreted directly on the data, and it allows for overlapping as well as nonoverlapping clusters. The method is similar to three-mode component models such as CANDECOMP and SUMMAX in the model function to predict the data. An application concerning recall data in a study of social perception is provided. [less ▲]

The present paper is concerned with methods of three-mode factor analysis to obtain a dimensional representation of three-way data. Classifying the methods by the number of derived spaces and their interrelations yields two distinct classes of models: CANDECOMP (Carroll & Chang, 1970), PARAFAC (Harshman, 1976) and SUMMAX (Orlik, 1980) rest on a basic trilinear decornposition of the data defining a separate space for each mode, whereas Tucker's (1964a thrce-mode factor analysis and SUMMA X in its extended form use a quadeilinear model specifying an additional core matrix. Associated with the current classification are different properties of the two model classes which refer to the number of substantial dimensions, their interpretation and the orientation of dimensions which is subject to rotations within the quadrilinear dass and uniquely determined by trilinear methods. Considering the different characteristics of the methods, formal relations between the classes have been found under very restrictive conditions only. However, there exist some general connections between trilinear and quadrilinear models. CANDECOMP and PARAFAC derive from the trilinear SUMMAX model by rescaling and permutation of axes, and the methodological link between the Tucker model and SUMMAX is given by orthogonal rotations of the SUMMAX configuration. These relationships are shown in an empirical example and their implications for the distinct concepts of individual differences within the two classes of methods are discussed. [less ▲]

The present paper is focused on the topic of a structural representation of adjectives describing interpersonal behavior in ordinary Janguage. 40 students of the University of Saarland were presented 117 adjectives selected on the basis of studies in the domain of verbal behavior descriptions by considering the concept of frequency of use. Subjects were asked to partition this set of adjectives into groups under the aspect of similarity of meaning. In order to analyse the relations between the investigated words and to provide a representation of all relevant relations simultaneously, the data of the sorting-task were inspected by hierarchical dustering and multidimensional scaling techniques. Thus a dimensional configuration reflecting inter-dass-relations was obtained and various dustering methods generated concordant dasses of adjectives which appeared to be interpretable at two different Ievels of analysis.
