Description
Summary:"The paper has established the transposability of theorems in psychophysics and mental test theory, has reduced both fields to a common postulational basis, has derived the basic theorems of the method of equal-appearing intervals and the law of comparative judgment from the basic postulates and specific assumptions, and has derived the parallel theorems for the mental test field. It has added a new concept to the field of mental test theory--the variability of an individual score--and has pointed out the possibility of scaling individuals by the analog of the law of comparative judgment."
