Three pigeons were trained on oddity matching in which either 1, 4, 8, 16, or 32 sample‐key observing responses were required to turn off the sample stimuli and turn on the comparison stimuli. Oddity accuracy increased when the observing‐response requirement was raised and decreased when the requirement was lowered. Next, while the observing requirement was maintained at one response, the number of responses required to the comparison stimuli was either 1, 4, 8, 16, or 32. Under these conditions, choice was defined as the comparison that first accumulated the required number of responses. In general, increasing the comparison‐response requirement decreased accuracy and lowering the comparison requirement increased accuracy. The fixed‐ratio observing requirements appeared to facilitate control by stimuli serving an instructional function.
