Sorting by activity counts in a novel open field predicts rats’ relative 9% ethanol intake. Left: activity counts positively correlate with later daily 9% ethanol intake. Right: rats sorted into “low”, “middle”, and “high” subgroups according to their different activity counts go on to drink different amounts of 9% ethanol. Values are mean ± S.E.M. *p < 0.05 vs. low subgroup.
