Abstract
A discrimination was established in a Skinner box in which the SD was a bright light for half the rats and a dim light for the remaining Ss. On the day following criterion performance all Ss were tested with the stimulus lights off (Extinction 1), followed by extinction with the original stimuli present (Extinction 2). In Extinction 1 all dim SD groups responded significantly more than all bright SD groups. In Extinction 2 all bright SD groups responded significantly more to SD than all dim SD groups. The results were as predicted by Spence’s discrimination model when no light is the lower end of the stimulus dimension; Zeiler’s adaptation level theory also accounts for the results.
