Tolerance to effects of cocaine on behavior under a response-initiated fixed-interval schedule.
Tolerance to effects of cocaine can be modulated by schedules of reinforcement. With multiple ratio schedules, research has shown an inverse relationship between ratio requirement and amount of tolerance that resulted from daily administration of the drug. In contrast, tolerance to the effects of cocaine on behavior under multiple interval schedules generally has developed regardless of interva...
متن کاملPrenatal methylmercury exposure increases responding under clocked and unclocked fixed interval schedules of reinforcement.
Recent experiments have suggested that developmental methylmercury exposure produces perseverative behavior in adulthood. In the present experiment, interactions between developmental low-level methylmercury (MeHg) and nutritionally relevant dietary selenium (Se) on operant behavior and its persistence were examined in aged animals. Female rats were exposed, in utero, to 0, 0.5, or 5 ppm mercur...
متن کاملSchedule-induced polydipsia as a function of fixed interval length.
Rats were trained to bar-press for Noyes pellets on an FI schedule which was increased serially through several values from 2 sec to as high as 300 sec. Concurrently, water was freely available. As FI length was increased, the degree of polydipsia increased linearly to a maximum value.
متن کاملInstrumental Uncertainty as a Determinant of Behavior Under Interval Schedules of Reinforcement
Interval schedules of reinforcement are known to generate habitual behavior, the performance of which is less sensitive to revaluation of the earned reward and to alterations in the action-outcome contingency. Here we report results from experiments using different types of interval schedules of reinforcement in mice to assess the effect of uncertainty, in the time of reward availability, on ha...
متن کاملReinforcement Schedule Effects on Long-Term Behavior Change.
OBJECTIVE The primary aim of this study was to determine whether different schedules of contingency management (CM), in conjunction with psychosocial treatment, produced different rates of abstinence and treatment attendance among individuals dependent on methamphetamine. METHODS Individuals were randomized into 1 of 3 conditions that sought to equate total potential reinforcer magnitude whil...
