Mean suppression ratio to the target cue (X; left) and the overshadowing cue (A; right) in Experiment 3. During training, X was paired with a surrogate outcome (S, which was later paired with a foot-shock US), either alone (in the Acq groups) or in compound with an overshadowing cue (A; in the OV groups). S-alone exposures were administered before X → S pairings in the Pre groups and after X → S pairings in the Post groups, whereas no S-alone exposure was administered in the Ctrl groups. Testing was conducted after a long (25-day) retention interval. Error bars represent the standard error of the mean.
