Perhaps an appropriate subtitle for this paper would be “Some Speculations on the Interrelations of Psychological Methodologies.” The Scale Grid is a name I have given to a model which presumes to define the underlying continuities between such diverse areas as psychophysics, objective testing, attitude studies including questionnaire and interview techniques, learning experiments, rating scale methods, essay examinations, and projective instruments. The intent of the Scale Grid is to make explicit the fundamental similarities and differences of the methodologies among these various areas of psychological research.

I wish to express my deep appreciation of the courtesies, assistance, and critical audience furnished me in the preparation of this paper by Professor H. C. J. Duijker and Professor A. DeGroot of the University of Amsterdam, while I was a Fulbright Research Fellow there in 1955—56.
