Figure 2.

Learning curves showing working memory performance by females and males across six blocks of training. Upper panels show number of WMEs committed during the first six choices of AE2. Lower panels show number of correct choices before making a WME during the first six choices of AE2. Data represent group means ± sem. *, Ovx females differed significantly from both intact and Ovx+E groups (P < 0.05); §, Ovx+E differed significantly from both intact and Ovx groups (P < 0.05); ††, Ovx differed significantly from intact group (P < 0.002 by comparison of marginal group means); §§, intact males differ significantly from castrate group (P < 0.05 by comparison of marginal group means).
