Abstract
Two experiments on classification were carried out with stimuli consisting of a pair of dots which could vary in Position, Distance between dots, and Orientation of the dots. In free classification, stimulus sets are presented to subject, who dichotomously classifies according to any attribute he chooses. In this task choices are affected by individual preferences for attributes as well as by discriminability of the attribute chosen and discriminability of competing attributes. In constrained classification, the subject is required to sort stimulus sets according to the attribute specified by experimenter and speed of sorting is measured. In this task, only discriminability of the criterion attribute affects performance.Keywords
