Abstract : The research activity led to a number of contributions of techniques for systematic study of individual differences in psychological phenomena. Much of this research was theory-oriented involving appropriate statistical and mathematical forms and computational procedures. In order to assess properties of procedures and validity of results, experimental trials were conducted of each technique considered using both simulated data and real observations. Work was concentrated on situations involving multiple observations of behavior of individuals. This emphasis led to consideration of various properties, applications, and extensions of factor analysis. The work of Professor Ledyard Tucker on determination of parameters of a functional relation by factor analysis was extended and applied to studies in psychological scaling, learning phenomena, and human judgment. A significant development involved the extension of factor analytic techniques from being limited to two-way tables of data to cases in which the data may be classified in three or more ways, or 'modes of classification'.
