Abstract
Serial dependency of components of the rat’s water-reinforced operant responding was observed after acute intraperitoneal ethanol injections (1.0 g/kg) and after an aversive CS+ tone. It was found that either the aversive CS+ or ethanol injections decreased behavioral variability, but there was no additional decrease in uncertainty of responding in a combined treatment group. The results were interpreted as support for Devenport and Merriman’s theory of the behavioral effects of alcohol and discussed in terms of possible control mechanisms involved.
