Skin conductance responses (SCRs) during the extinction memory recall test. Mean differential SCRs during the first two trials of the CS+E minus the first two trials of the CS+U during the extinction memory recall test. Difference scores greater than zero reflect greater responding to the CS+E, difference scores equal to zero reflect no difference in responding between the CS+E and CS+U, and scores less than zero reflect greater responding to the CS+U (LaBar et al., 1998; LaBar et al., 1995). PBO (green bars) and THC (red bars).
