Experiment 2: Trauma context test on Day 3. Mean percent time freezing (± SEM) in the trauma context 1 day following the novel context memory test. The no trauma group (n = 12) showed no fear to this environment, while the trauma/no extinction (Ext) group (n = 12) showed a high level of fear. A one-way ANOVA revealed significant differences among the groups p < 0.001. Tukey’s HSD tests specified that levels of freezing in the 72-h extinction group (n = 12) were significantly different from the trauma/no extinction group, p < 0.05. The 10-min extinction group (n = 12) did not significantly differ from the trauma/no extinction group.
