Comparisons across valences (loss vs. gain) and across amounts (50 vs. 10) are illustrated in Fig. 8 along with Bonferroni adjusted significance levels. For the ORP measures, both Gain and Large amount ‘50’ conditions showed significantly higher amplitude and shorter latency than Loss and Small amount ‘10’ conditions respectively, in control as well as alcoholic groups. The findings in ORN measures are: 1) amplitude differences between valences (loss vs. gain) were obvious only in the alcoholic group (panel A-1), whereas latency differences were explicit in both groups (panel B-1); and 2) Alcoholics, in contrast to controls, showed more ORN amplitude for small amount ‘10’ than for Large amount ‘50’ (panel A-3).
