CSOBAN MIRKA, Eugenia. Role of contextual keys on the occurrence of the state-dependent learning phenomenon. Interam. j. psychol. [online]. 2008, vol.42, n.1, pp. 11-18. ISSN 0034-9690.

The role of context on the occurrence of state-dependent learning was explored in this research. The laboratory experiment was done with four groups of rats (Sprague-Dawley). Three groups were trained with an RF10 reinforcement program under the effects of 2,5mg/kg of diazepam and with the presence of a tone and a camphor solution. The last group received the same treatment but without diazepam. The role of context was tested first, varying either one or all training conditions. After extinction, drug or context effects were tested alone or in combination. State-dependent learning occurred when the tests were carried out without diazepam but did not occur in the absence of the stimuli of the context. Responses were under the control of diazepam while the context didn't have a discriminative function, neither during response acquisition nor after the extinction.
