Frequency distribution of rejection volumes for male and female rats across all delays tested. The dotted lines indicate the percentages of animals exhibiting optimal reward maximization. Gray shaded regions represent the percentages of animals exhibiting overharvesting, whereas the open boxes represent the percentages of animals exhibiting underharvesting at delays of 0 s ((a) males; (b) females), 6 s ((c) males; (d) females), 12 s ((e) males; (f) females), 18 s ((g) males; (h), females), and 24 s ((i), males; (j), females). n = 896 (males) and 898 (females).
