The stimulus set was represented by an a priori stimulus classification model, defined by positions (i.e., degrees of arc) on a unit circle that specified the relationships among the form and color features. An analysis of YEP deviation wave shapes (VEP: deviations around average YEP for each electrode) showed that the a priori unit circle model predicted morphologies of the YEP wave shapes, as well as the overall relationships between wave shapes obtained for the form and the color attributes. Further analyses demonstrated that individual 6. YEP wave shapes for color and for form were located on the circumference of a unit circle at the positions (angle) specified by the a priori model. The studies show that formal modeling of the way humans classify stimulus attributes provides a quantitative and predictive model of the way VEPs become classified and organized according to psychological principles. @ 1993 Academic Press, Inc.
