OF LEARNING UNDER MOTIVATED AND SATIATED CONDITIONS IN THE WHITE RAT * BY HOWARD H. KENDLER * University of Colorado The influence on learning of satisfying acts and their conse- quences has been one ...
2, rats were extinguished or were run while satiated following deprived acquisition, and then were either shifted to the other condition or maintained under the same condition . A greater response ...
Employing a 4-unit maze, and a 10-unit elevated T-maze, groups of albino rats were run under differing conditions of hunger and satiation for the purpose of testing the hypothesis of externalization ...
so and thus we do not expect them to perform optimally (for reference see [42]). Gradient model. The first model we used to describe learning of synaptic weights under changing conditions , directly ...
. Previous lesion studies have suggested that vmPFC damage produces changes in preference, value comparison , future thinking and motivational modulation of action (Fellows, 2005; Wheeler and Fellows, 2008 ...
, are confounded by satiation , which reduces reward salience. Therefore, rodents are commonly food- or water-restricted prior to task performance to increase the motivational salience of an appetitive reward ...
) in each task. The number of training sessions required for a subject to reach criteria relied solely on the subject’s performance. Subjects were tested under two conditions : “high satiation ” (henceforth ...
Introduction Rodents, in particular rats and mice, have long been used in behavioral studies exploring the mechanisms underlying learning and memory [1,2]. Such experiments are particularly valuable ...
is a wasted opportunity). Given that sloth is energetically inexpensive (and thus appealing), the average reward theory predicts that the animal will occupy this motivational state under low DA conditions ...
