Abstract
Steady-state accuracy on matching to sample was studied in the pigeon. In Phases 1 and 3 of the experiment, geometric forms were used as stimuli. In Phase 2, the stimuli were colors. In each phase of the experiment, four comparison stimuli were used. Matching accuracy was substantially higher in the color matching phase than in either form matching phase. This result shows that steady-state differences in accuracy exist, under some conditions, between form matching and color matching. This finding extends the theory that differences between form and color matching exist in acquisition.
