“…The animal can overcome the disorganizing effect of high levels of activation when the response is made stronger. Granger (1969) has already shown that for a simple task (runway) there is no drop in performance. The results given here show that for a more complex task (Skinner box), the drop in performance can be prevented by overtraining or training under high activation.…”

In Experiment 1, 2 groups of 9 rats were trained in a Skinner box under 24 hr. of water deprivation. Group 1 was trained for 15 daily training sessions, compared with 30 sessions for Group 2. In Experiment 2, 4 groups of 9 rats were also trained in a Skinner box but under different conditions of water deprivation (24, 36, 48, and 60 hr., respectively). In both experiments, the relationship between performance and activation was evaluated by submitting each group to successive and independent conditions of water deprivation (24, 36, 48, 60, and 72 hr.). Heart rate was used as an index of activation during training and during the test phase. The major findings were that overtraining (Experiment, 1) and high activation during training (Experiment 2) could prevent the occurrence of the drop in performance usually observed under high levels of activation.1 This article is based on a dissertation submitted by the author in partial fulfillment of the requirements for the doctoral degree at TJniversit6 de Montreal.

A review is presented as to the neurochemical basis of the straight runway task, usually consisting of an acquisition phase followed by an extinction phase. During the acquisition of the appetitive runway task, running speeds from the start box to the goal box progressively increase over trials and then decrease when the reward is withheld. Runway extinction is susceptible to lesions of the limbic system, including the medial frontal cortex, the hippocampus, the septum, the amygdala, and the dorsomedial thalamus. When specific neurotransmitter systems are examined, extinction was delayed when noradrenaline transmission was impeded, perhaps involving noradrenergic projections to the hippocampus and neocortex. Extinction was likewise delayed after either facilitation or blocking of dopamine transmission, a result implicating an inverted U-shaped function caused by dopamine’s role in behavioral activation or reward processes. Extinction was also delayed by indirect GABAA receptor agonists injected during acquisition, explained by druginduced disinhibitory tendencies. This simple paradigm may provide information about the effects of a physiological manipulation on both cognition and emotion.
