Comparison 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...
متن کاملEffects of phentermine on responding maintained under multiple fixed-ratio schedules of food and cocaine presentation in the rhesus monkey.
Drugs that decrease drug-maintained responding at doses that do not decrease other behaviors in animals may be suitable candidates for development as medications to treat drug abuse in humans. The present study examined whether this effect could be obtained with phentermine, a drug that has been reported to decrease cocaine intake in humans. Rhesus monkeys were trained under multiple fixed-rati...
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 کاملReinforcer magnitude and demand under fixed-ratio schedules with domestic hens.
This study compared three methods of normalizing demand functions to allow comparison of demand for different commodities and examined how varying reinforcer magnitudes affected these analyses. Hens responded under fixed-ratio schedules in 40-min sessions with response requirement doubling each session and with 2-s, 8-s, and 12-s access to wheat. Over the smaller fixed ratios overall response r...
