Abstract:

Albina rats, trained on a multiple fixed-ratio FR, differential reinforcement of low rate DRL schedule for food reinforcement were repeatedly exposed to increased pressure equivalent to 100, 200, and 300 feet of sea water breathing compressed air or an 80 helium-20 oxygen mixture Heliox. Response rates on the two schedules were less disrupted when the heliox mixture was used, although decrements in performance were still observed. Repeated exposure to the same depths produced some behavioral adaptation to pressure effects. Differential rate changes on the two schedules under hyperbaric conditions were observed as a function of schedule contingencies. Author
