Animals trained during the active phase of the light cycle showed a trend toward committing more reference memory errors than animals trained during the inactive phase ( F 1,22 = 3.8, p < 0.065); this effect interacted with day of training ( F 4,88 = 3.0, p < 0.03) such that the difference between active vs. inactive phase trained animals diminished over training ( p < 0.02 on first day of training; comparisons on other days not significant, Figure 6 A).
