Experiment 2: Extinction sessions 1–5 for 10-min extinction and 72-h extinction groups. Mean percent time freezing (± SEM) during the first 8 min of each trauma context (A) extinction (Ext) session. The delayed (72 h) extinction group (n = 12) showed higher levels of freezing compared to the immediate (10 min) extinction group (n = 12). A mixed-design ANOVA revealed results similar to those observed in Experiment 1; there was a significant main effect of both group and extinction sessions p < 0.001 but no interaction. A planned post-hoc t-test revealed that freezing was not significantly different between the groups by the final extinction session.
