Journeymen electronics maintenance personnel judged the complexity of 16 avionics circuits using four different psychological scaling procedures on two separate occasions. The scale values representing these eight variables were intercorrelated the resulting coefficients were factor analyzed separately for each of the 16 circuit stimuli to test the hypothesis that two factors would account for the data. After considering one, two, three, and four factor solutions, a two factor solution was chosen. These two factors suggested the taxonomy of cognitive discrimination and contextual uncertainty to account for the subjects scaling behavior. Most frequently, the paired comparison and the constant sum methods were loaded heaviest on factor 1, cognitive discrimination. The rank order and the magnitude estimation methods were most consistently loaded heaviest on contextual uncertainty, factor 2. The findings are interpreted in their relationship to certain customary psychological scaling classificatory schemes. Author
