Some effects of the interfood interval on schedule-induced drinking
Schedule-induced drinking was studied in four male albino rats when food was presented at regular intervals ranging from 15 to 480 secs. Water was available at all times during the course of the experiment. Several measures of schedule-induced drinking were examined as a function of the interfood interval. The measures were referred to as reflecting either the strength of drinking or its temporal location. The temporal location was assessed by determining the frequency distribution of both time between pellet delivery and the first lick (initiation time) and time between pellet delivery and the last lick (termination time)

Schedule-induced drinking: rate of food delivery and Herrnstein's equation.
Schedule-induced drinking was measured in four rats exposed to fixed-time schedules of food ranging from 30 to 480 seconds. Herrnstein's (1970, 1974) equation relating rate of a single response as a hyperbolic function of reinforcement rate provided a good fit to three measures of drinking: lick rate, ingestion rate, and relative time spent drinking. The functions relating the three measures of drinking to reinforcement rate were of similar form. Herrnstein's equation also provided a good description of some already published data on schedule-induced drinking. The fit both to the present data and to the already published data was improved somewhat by computing the measures by subtracting from the time base a latency constant representing the minimal time required to consume the food pellet and travel to the water source. The data from this study provide two correspondences between operant behavior and schedule-induced behavior: (a) conformity to Herrnstein's equation and (b) equivalence of rate and relative time measures
