Schedule-Induced Polydipsia: An Atypical Case
An atypical case of drinking and bar-press behavior in a rat exposed to time-dependent and response-dependent food schedules is described. The analysis indicated that schedule-induced behaviors in some Ss may be related to a failure to discriminate programmed from non-programmed (i.e., adventitious) response contingencies and that parametric manipulation of the schedule requirements, as well as a temporal and sequential analysis of responding in the inter-pellet interval is needed to assess the degree of dependence of responding upon scheduled food delivery.
