After having initially been trained for a classroom demonstration, a pigeon was tested for retention following a 12-year period without intervening training. Strong evidence was obtained of stimulus control and substantial evidence was found of schedule control by the fixed-interval and fixed-ratio components of the multiple schedule used in initial training.
