Figure. 4. The reduction of stimulus discrimination from block 1 to block 4 during extinction.
Paired sample t-tests confirmed significant and gradual reduction of stimulus discrimination (CS+ minus CS-) in the reminder+OT group (R+OT), but not in the reminder+placebo group (R+PLC) or the no reminder+OT group (NR+OT). *P < 0.05, ** P < 0.01. Error bars represent standard errors.
