Figure 3.

(A) Overall freezing during a 4 minute test of CFC. Planned comparison identified significant levels of freezing in 240, 152 and 30 sec groups relative to the 3 sec PSI group (p < .05) (B-E) Freezing during each test minute of the 4 minute test of CFC. 3-way analysis of variance (ANOVA) for Sex and PSI (30, 152, 240 sec) as between subject factors and Test Minute (1–4) as a within subject factor identified a significant sex difference at minute 1 for (B) 240 (p<.05), but not (C) 152 (p=.07) sec, (D) 30 sec, or (E) 3 sec PSI; n=54, 6–9 animals per group. * denotes significant difference between males and females at minute 1, while colored * denotes significant difference within sex.
