For “POMS”, the mean change in self-reported mood score (post-stimulation minus pre-stimulation) is reported for each of the six factors of mood items (tension-anxiety, depression-dejection, anger-hostility, vigor-activity, fatigue-inertia, confusion-bewilderment). For “Forced Choice Arousal”, the numbers of participants reporting “increased,” “decreased,” or “no change” in arousal for each stimulation condition are reported. For “SCRs (IAPS)”, mean SCRs to each picture type (neutral and arousing) are reported, with standard errors in parentheses. For “Subjective Ratings (IAPS)”, mean subjective arousal ratings to each picture type are reported, with standard errors in parentheses. For “Moral Judgment”, mean levels of endorsement of the proposed action are reported, with standard errors in parentheses. For “CalCAP”, mean RT differences (post-stimulation minus pre-stimulation) for each subtest (CRT and SRT) are reported in msec, with standard errors in parentheses. There was no significant effect of stimulation condition on any of the measures.
