(A) Experimental protocol for Experiment 5. (B) Mean (±SEM) serum estradiol levels during the different phases of the experiment. T2 * = p< 0.05; Placebo vs. Estradiol. (C) Mean (±SEM) differential SCRs during conditioning, and differential SCRs during early and late extinction. * = p<0.05; Early vs. Late Ext. (D) Mean (±SEM) percent recovery of SCRs at extinction recall in Experiment 5 (Ns = 15–16/group). * = p<0.05; Placebo vs. Estradiol (E) A selection of estradiol (N = 13) and placebo-treated (N = 10) women were matched for conditioning strength. Estradiol-treated women exhibited significantly less percent recovery of fear at extinction recall than placebo-treated women when matching for conditioning strength. * = p< 0.05; Estradiol vs. Placebo.
