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 کاملPreference between variable-ratio and fixed-ratio schedules: local and extended relations.
Although it has repeatedly been demonstrated that pigeons, as well as other species, will often choose a variable schedule of reinforcement over an equivalent (or even richer) fixed schedule, the exact nature of that controlling relation has yet to be fully assessed. In this study pigeons were given repeated choices between concurrently available fixed-ratio and variable-ratio schedules. The fi...
متن کاملExtended pausing by humans on multiple fixed-ratio schedules with varied reinforcer magnitude and response requirements.
We conducted three experiments to reproduce and extend Perone and Courtney's (1992) study of pausing at the beginning of fixed-ratio schedules. In a multiple schedule with unequal amounts of food across two components, they found that pigeons paused longest in the component associated with the smaller amount of food (the lean component), but only when it was preceded by the rich component. In o...
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...
