Abstract
In experiment 1 the species generality of schedule-induced polydipsia was investigated by exposing two chinchillas (Chinchilla lanigera) to a series of fixed-interval schedules ranging from 15 to 180 seconds and exposing four other chinchillas and two Long Evans hooded rats to a series of fixed-time schedules ranging from 15 to 180 seconds for two chinchillas and 15 to 240 seconds for the other subjects. It was found that all subjects increased their water intake over apparatus baseline levels when exposed to the intermittent schedules, that the rats drank more than any chinchilla subject, and that the chinchillas exposed to the FI schedules drank more than the chinchillas exposed to the FT schedules, but, conclusions on the effects of a response requirement would be premature. An analysis of the temporal distribution of licking after food delivery showed that chinchillas tended to drink in the first 30 seconds post-food, but that licking occured at later times also. In experiment 2, four other food-deprived chinchillas were exposed to 100 sessions of FT 30 then 100 sessions of FI 30 in an environment that provided the opportunity to drink, run, sand-bathe, socialize, tunnel, gnaw, eat, and lever press. The proportion of time occupied by these responses in a session, the temporal distribution of responses within the interfood-interval, and the sequencing between response categories were measured. It was found that chinchillas exposed to FT and FI 30 schedules of food delivery developed reliable patterns of responding in the inter-food interval. These patterns varied from chinchilla to chinchilla and between schedule types. Drinking was found to be enhanced on both schedules. The sequential analysis of responding found that the FI schedule produced more switches among responses and that the sequencing of responses was determined by food delivery, while the sequence found during baseline were reflected response preference. The results of experiment 1 and 2 discussed in terms of the current controversy over what constitutes a schedule-induced response.
