Mean percentage freezing (± SEM) during the training session (post-shock) and the context (CTX) and tone tests in Experiment 2A (panel A) and Experiment 2B (panel B). In Experiment 2A, training took place before surgery. After recovery from surgery, context fear was assessed in Context A (CTX A) and tone-specific fear was assessed in Context B. In Experiment 2B, re-training occurred in Context B, context fear was assessed in Context B (CTX B1) and tone-specific fear was assessed in Context C. *p < .05
