THE PSYCHOLOGICAL DIMENSIONALITY OF BASIC ELEC TRONIC CIRCUITS: I. THE STABILITY OF THE SCALING TECHNIQUES,
Abstract
This is the first of a series of reports concerned with the use of multidimensional scal ing in identifying electronic circuit character istics which make their functions difficult for electronics technicians to understand. Thirteen basic electronic circuits were analyzed. Scale values for the 78 possible circuit-pairs were derived by the multidimensional method of successive intervals. These were converted to interstimulus distances, which were analyzed for minimum dimensionality by three current methods of multidimensional scaling. Six dimensions were extracted. The first three of thea accounted for most of the variance in the interstimulus space. This report presents data on the reli ability of these multidimensional procedures. Estimates of reliability were computed for the successive steps in the method; inclugnng intra subject stabilities across replications, distance scale stabilities, and coefficients of congruence for final dimensions across replications, groups, and methods.
