Six hundred and ninety six preschoolers were trained on two-choice discrimination problems. Stimuli were geometric figures differing in form and color. In analysis I with form relevant and color irrelevant, a square-triangle problem was learned more readily than a circle-triangle problem, and a circle-triangle more readily than a cross-star problem. In analysis II with color relevant and form the same, no significant difference was found between red and blue in each pair. In analysis III with form relevant and color irrelevant (two dimensions), square-triangle problems were learned more readily than circle-triangle problems, and circle-triangle more readily than cross-star problems. In analysis IV with color relevant and form irrelevant (two dimensions), no significant difference was found between red and blue in each pair-set.
