Figure 3

Mean time (±SEM) spent on the grid floor during five daily 60-min test sessions. The top panels depict Exp. 1 in which mice were trained and tested in the dark; the bottom panels depict Exp. 2 in which mice were trained and tested in the light. In one-compartment procedures, mice had access to the entire apparatus during conditioning trials (no barrier between sides) and the same floor cue was on both sides. In the two-compartment procedures, mice were confined to the left or right side of the apparatus on the assigned floor. Only the main effect of Conditioning Subgroup was significant (p < .0001) in the dark condition. That main effect (p < .0001) and the Conditioning Subgroup x Number of Compartments interaction (p < .05) were significant in the light condition. Each conditioning subgroup contained 11–12 mice.
