"JEAB"'s first decade featured control of individual behavior by operant contingencies, where the experimenter could interact with a subject in real time and obtain fairly immediate evidence of control, with the possibility of direct extension to applied settings. In subsequent decades, emphasis shifted toward long-term parametric studies with…

Recent progress in mouse genetics has led to an increased interest in developing procedures for assessing mouse behavior, but relatively few of the behavioral procedures developed involve positively reinforced operant behavior. When operant methods are used, nose poking, not lever pressing, is the target response. In the current study differential…
