Spatial aversion conditioning with ethanol.

To determine whether dose level affected ethanol's ability to establish a preference or aversion for an associated spatial location, two groups of male albino rats each received five pairings of an IP injection of ethanol (1 or 2 g/kg) with exposure to a distinctive compartment for 15 min. On alternate days, each rat was exposed to a different compartment after a saline injection. A choice test indicated that aversions were established at both dose levels, and thus failed to confirm a previous report of conditioned location preference at the lower dose level.
