Applied implications of reinforcement history effects.

30 Dec 2008 Although the influence of reinforcement history is a theoretical focus of behavior analysis, the specific behavioral effects of reinforcement history have received relatively little attention in applied research and practice. We examined the ...

Progressive ratio schedules of reinforcement.

30 Dec 2008 Pigeons' pecks produced grain under progressive ratio (PR) schedules, whose response requirements increased systematically within sessions. Experiment 1 compared arithmetic (AP) and geometric (GP) progressions. Response rates increased as a function ...

Effect of reinforcer magnitude on performance maintained by progressive-ratio schedules.

30 Dec 2008 This experiment examined the relationship between reinforcer magnitude and quantitative measures of performance on progressive-ratio schedules. Fifteen rats were trained under a progressive-ratio schedule in seven phases of the experiment in which ...

The probability of small schedule values and preference for random-interval schedules.

30 Dec 2008 Preference for working on variable schedules and temporal discrimination were simultaneously examined in two experiments using a discrete-trial, concurrent-chains arrangement with fixed interval (FI) and random interval (RI) terminal links. The ...

A comparison of four models of delay discounting in humans.

25 Dec 2008 The present study compared four prominent models of delay discounting: a one-parameter exponential decay, a one-parameter hyperbola [Mazur, J.E., 1987. An adjusting procedure for studying delayed reinforcement. In: Commons, M.L., Mazur, J.E., Nevin, ...

Whisking in air: encoding of kinematics by trigeminal ganglion neurons in awake rats.

22 Dec 2008 Active sensing requires the brain to distinguish signals produced by external inputs from those generated by the animal's own movements. Because the rodent whisker musculature lacks proprioceptors, we asked whether trigeminal ganglion neurons encode ...

Early deprivation leads to long-term reductions in motivation for reward and 5-HT1A binding and both effects are reversed by fluoxetine.

22 Dec 2008 Early life stress is a risk factor in aetiology of depression. In rats, early life stress can lead to pro-depressive biomarkers in adulthood. The present study in male Wistar rats investigated the effects of early life deprivation and fluoxetine on ...

Alterations of prodynorphin gene expression in the rat mesocorticolimbic system during heroin self-administration.

8 Dec 2008 Opiate-induced alterations in the gene expression of the opioid propeptides prodynorphin (PDYN) and proenkephalin (PENK) in the brain have previously been described. However, there are no studies examining opioid propeptide system alterations due to ...

Self-administration of cocaine-pentobarbital mixtures by rhesus monkeys.

Dec 2008 A number of experiments have evaluated self-administration of the combination of a stimulant and an opioid. Less is known about the combination of a stimulant and a CNS depressant. The present experiment was designed to examine self-administration ...

Reinforcement magnitude modulation of rate-dependent effects of fluvoxamine and desipramine in the rat.

29 Nov 2008 Reinforcement magnitude modulates the effects of the antidepressants fluvoxamine and desipramine in the pigeon. Increasing reinforcement magnitude diminishes the rate-dependent effects of these drugs. Whether this is also the case in other species ...
