Figure 4.
A retrieval trial after extinction is more effective in reducing fear recovery when presented shortly after extinction than when delayed. (A) Mean (±SEM) levels of CS-elicited freezing for retrieval either 10 min or 6 h after extinction in Experiment 4. (B) Mean (±SEM) levels of CS-elicited freezing at test in the extinction context B and the training context A in Experiment 4 (n = 15 for each group).
