In the drug-present preference test, MALDR-2 mice exhibit CPA, regardless of dose. Shown are mean ± SEM sec/min on the grid floor (A) and beam breaks (B) measured during 30-min place preference tests for animals conditioned with MA on the grid (G+) or hole (G-) floor. Measurements were taken in a drug-present preference test in which animals (n = 7-13 per line, group and dose; see text for explanation of reduced n) were administered MA before the test. Differences in pharmacological effects of MA during the same place preference test (C) are also presented as, percent (%) time on MA-paired floor. ***p<.001 for the main effect of conditioning group (A) and, for the main effect of line (C). †††p<.001 for the main effect of dose (C). MAHDR-2, MA high drinking replicate 2; MALDR-2, MA low drinking replicate 2.
