Abstract In the present investigation we studied the effect of caffeine on memory task inhibitory avoidance and habituation to a new environment. Caffeine impaired retention scores in mice submitted to inhibitory avoidance and habituation when administered 30 min before training at the doses of 10-30 mg/kg. These effects cannot be explained by state-dependency since the administration of caffeine 30 min before the test session did not reverse the effect of pre-training caffeine administration, but can more probably be explained by an impairment in the acquisition or by interference with attentional processes. On the other hand, caffeine improved the inhibitory avoidance (but not habituation) retention scores when administered immediately after the training or 30 min before the test session at the doses of 1-30 mg/kg or 3-10 mg/kg, respectively. These results suggest that caffeine differentially affects the different stages of memory processing and that this effect depends on particularities of the memory task under study.
