Association of endogenous testosterone/cortisol ratio levels, obtained during the morning, with fear and extinction learning. Participants with preconditioning high salivary testosterone to cortisol (T/C) ratio (based upon median split of 39 participants with testosterone data who had Session 1 in the morning) show better extinction learning. Significance indicated for the T/C ratio main effect (large asterisk) and trial-by-trial (small asterisk). SCR1/2d: differential SCR, * p < .05 trial, ** p < .01. Error bars depict standard error of the mean.
