Comparisons of mean scores (± SEM) of the same eight inbred strains on the same tests in three independent experiments done at the University of Windsor. Experimenters differed across all 3 experiments. The three data sets for a single test are plotted with the same scale on the X axis, and a dashed line is drawn at the same value of X across the three graphs to facilitate comparisons. A. Experiment 1 involved independent groups of mice that received saline and ethanol but no other treatment. B. Experiment 2 shows strain values averaged over two light-dark cycle conditions. C. Experiment 3 shows values averaged over standard and enriched housing.
