A. Acoustic eyeblink startle response elicited during the viewing of affective faces (rectified, smoothed, and baseline-corrected raw EMG signal averaged across participants within each facial expression category). B. Magnitude of the startle response (M±SE) elicited in male and female observers as a function of facial expression category. Data corrected for habituation effects are shown (residual values from regression analysis over 46 startle trials).
