The ANOVA for wall-climbing scores in adolescent subjects yielded a significant interaction between treatment during conditioning and ethanol dose, F(2, 68) = 3,79; p< 0.05. Post-hoc tests indicated similar levels of wall-climbing in P33 animals given 0.5 g/kg, regardless of nature of the contingency between sucrose and ethanol in Phase 1. In contrast, adolescents in groups EP and LP previously given 2.0 g/kg ethanol during Phase 1 exhibited more wall climbing during the transfer phase (in which no ethanol was given) than their unpaired controls (both ps < 0.05). Descriptive data (i.e., means and standard errors) relative to locomotion, head-shaking and wall-climbing can be found in Table 1.
