This study examines the psychometrics of the perceptual component of the Style Analysis Survey (SAS) [Oxford, R.L., 1993a. "Style Analysis Survey (SAS)." University of Alabama, Tuscaloosa, AL]. The study is conducted in the context of questions over another perceptual learning-styles instrument, the "Perceptual Learning Styles Preferences questionnaire" (PLSP) [Isemonger, I.M., Sheppard, C., 2007. "A construct-related validity study on a Korean version of the Perceptual Learning Styles Preference questionnaire." "Educational and Psychological Measurement" 67 (2), 1-12; Reid, J.M., 1984.

"The construct validity of one learning-styles instrument." "System" 29, 385-403], and questions surrounding the usefulness and operationalization of learning styles generally [Curry, L., 1990. "A critique of the research on learning styles." "Educational Leadership" 48 (2), 50-55; Ferrari, J.R., 1996. "Psychometric properties of the revised Grasha-Riechmann student learning style scale."

"Educational and Psychological Measurement" 52, 701-708; Moran, A., 1991. "What can learning styles research learn from cognitive psychology." "Educational Psychology" 11, 239-245]. The study aimed to address the psychometrics of the perceptual constructs of the SAS, and by extension the issue of whether the problems with the PLSP are peculiar to the instrument or one instance of a more general problem with learning-styles instruments measuring perceptual constructs. The findings indicate possible problems with the perceptual constructs on the SAS, and raise the question of how well perceptual constructs operationalize. (Contains 2 figures and 2 tables.)
