Figure 4.
Reacquisition does not differ as a function of the extinction session duration. (A) Overview of the design of Experiment 4. The times listed represent the total time of exposure to the context for a given session. A “+” sign indicates a single 0.75 mA shock and a “−” sign indicates the exposure to the context without shock. (B) Mean freezing during each extinction session. (C) Mean freezing during the test for each group. Tick marks on the X-axis reflect 3-min time blocks. Error bars represent standard error of the mean.
