Self-report ratings before and after startle probe sessions as a function of drug dose. Data represent mean values (±SEM). Overall arousal ratings were similar before and following test sessions but higher after meclizine administration (both doses) than after placebo intake (top-left panel). Mean valence ratings decreased after test sessions but were not affected by meclizine (top-right panel). Similarly, drowsiness levels increased continuously after pill intake and throughout testing but were not differentially affected by drug condition (bottom panel).
