BETANCOURT MAINHARD, Ronald; INOSTROZA PARODI, Marion  e  LABORDA ROJAS, Mario A.. Ocassion setting of associative tolerance to ethanol. Rev. Latinoam. Psicol. [online]. 2008, vol.40, n.2, pp. 243-257. ISSN 0120-0534.

There is evidence that drug-paired cues not only become associated with the drug effects but also become occasion setters that modulate the association of other cues with the drug effects, contributing to the development of associative tolerance (Ramos, Siegel, & Bueno, 2002). Using a feature-positive discrimination training, we evaluated the contribution of contexts as occasion setters of the ataxic effect of ethanol in rats. The results suggest that the context acquire occasion setter properties of the drug tolerance, and that these properties can be extinguished.
