Effects of cocaine on briefly signaled versus completely signaled delays to reinforcement

Article Abstract:

Chronic and acute administration of cocaine induce different rates of key pecking in pigeons. Two sets of pigeons show similar behavioral responses whether delays were briefly or completely signalled. Chronic cocaine administration makes the pigeons tolerant to the rate-decreasing effects. For acute administration, while larger doses reduce the response rates, small to intermediate doses results in an increase, or in no change. Brief and complete delay signals are equally effective as conditioned reinforcers in maintaining key pecking by pigeons.

How research in behavioral pharmacology informs behavioral science

Article Abstract:

Behavioral pharmacology is a maturing science that has made significant contributions to the study of drug effects on behavior, especially in the domain of drug-behavior interactions. Three general strategies are outlined in behavioral pharmacology research that are employed to increase understanding of behavioral processes and examples are provided of the general characteristics of the strategies and of implications of previous research of behavior theory.

Some questions about unification of conditioning processes, stimulus-response psychology, and neural network models

Article Abstract:

Donahoe, Palmer and Burgos have stirred people in the discipline to become critically aware of the conditioning processes. The clear characterization of behavioral science as historical science was one point generally appreciated. However, questions with regards to the vagueness of the idea on the unification of the concepts, as well as the use of neural network models, were raised.
