Abstract
When bar-pressing was reinforced with 45 mg Noyes pellets scheduled once per min on the average (VI 1), three rats drank more when 0.4% (w/v) saccharin was freely available than when the fluid was plain water. They consumed more saccharin than water under extinction (ext) conditions also, but not under a continuous schedule of reinforcement (crf). Saccharin consumption was less under crf than under ext, in accord with the observation that water-drinking occurs only immediately after eating (post-pellet) but that saccharin-drinking occurs on other occasions in addition (inter-pellet). Post-pellet drink durations of saccharin and of water were relatively stable within sessions, but inter-pellet drinking was erratic. Apparently palatability is not a factor in the post-pellet drinking responsible for schedule-induced polydipsia but is a stimulus for drinking in addition to that which is schedule-induced.
