Approximating Implicit Objects,t the evaluation of manipulated variables. When a variety of restrictions on ethanol availability have been imposed, sensitive self-administration baselines have been established which have permitted the direct experimental assessment of some of the determinants of ethanol self-administration.

Bernard Dacorogna,Paolo Marcellinieby the subsequent drug effect. Experiments measuring the depletion of catecholamines following synthesis inhibition with αMT, or changes in the specific activity of norepinephrine after tritium labeling, have shown that operant behavior alters the metabolism of catecholamines.

What is needed are a series of sensitive measures that might, together or separately, indicate the presence of a potentially poisonous substance.gentle 发表于 2025-3-28 04:18:14

Adding a discriminative stimulus when the response requirement was fulfilled increased the likelihood that a switch would occur only after the appropriate number of pecks had been em
