Concurrent drinking by pigeons on fixed-interval reinforcement schedules.
Three experienced pigeons were exposed to at least ten consecutive 100-min sessions on each of three food-reinforced fixed-interval (FI) schedules: FI 50-sec, FI 100-sec and FI 200-sec. Water was freely available. Drinking was largely confined to the first third of each fixed interval, and the mean sessional water intake was directly related to the food-reinforcement rate for each animal. The a...

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 کاملThe effects of variable-interval and fixed-interval signal presentation schedules on the auditory evoked response.
Averaged auditory evoked responses to 1000-Hz 20-msec tone bursts were obtained from normal-hearing adults under two different intersignal interval schedules: (1) a fixed-interval schedule with 2-sec intersignal intervals, and (2) a variable-interval schedule of intersignal intervals ranging randomly from 1.0 sec to 4.5 sec with a mean of 2 see. Peak-to-peak amplitudes (N1P~) as well as latenci...
متن کاملComparison of fixed-ratio and progressive-ratio schedules of maintenance of stimulant drug-reinforced responding.
The effectiveness of doses of i.v. cocaine and nomifensine in maintaining lever-press responding in rhesus monkeys was evaluated under two schedules, fixed- and progressive-ratio (FR, PR). The doses that maintained maximum rates of responding under the fixed-ratio schedule were 0.32 mg/kg per injection cocaine and 0.10 mg/kg per injection nomifensine. The fixed-ratio rates maintained by this do...
