Behavioral variables were analyzed by separate two-way mixed analyses of variance (ANOVAs). The between-group factors were treatment during conditioning [unpaired (UP), early pairing (EP) or late pairing (LP)] and ethanol dose (0.5 or 2.0 g/kg). The loci of significant main effects or interactions were further examined by means of pairwise post-hoc comparisons (Fisher’s Least Mean Significant tests, with alpha level set at 0.05).
