Analysis of BDI scores yielded a main effect of Drinker Status, F 1, 32)=6.79, p=0.014, and no other significant effects, p's>0.07.
The ANCOVA of Confidence to Resist Gambling under AMPH yielded a main effect of Gambler Status, F 1, 31)=5.18, p=0.030, and no other significant effects, p's>0.15 (panel h).
A 2 × 2 × 5 ANOVA of RT to the five types of words under placebo yielded a main effect of Word Condition, F 4, 128)=10.95, p<0.001, and no other significant effects, p's>0.22.
Repeated NTG episodes also yielded a main effect for locomotor activity (Panel B), F 2,27) = 4.53, p = .02, in which mean photobeam breaks in the 3- and 5-NTG groups were significantly lower than the 0-NTG control group (ps = .036 and.04, respectively).
A repeated-measures ANOVA yielded a main effect of stimulus on intensity ratings [F 7, 77) = 19.97, p<.0001].
Thus, acceptability yielded a main effect, F 1,31) = 26.4, p<.001, whereas there was no effect of matching nor an interaction, Fs<1.
An analysis of duration of background fixations yielded evidence for a main effect of culture, due to longer fixation durations to backgrounds in the US participants compared to the Singapore participants (F 1, 29) = 7.67, p<.01, η2 = .21; 220.6 ms vs. 151.6 ms).
A mixed model ANOVA Groupp × Zone) yielded a borderline main effect of Group, F 1, 21) = 4.25, p =.052, a significant main effect of Corner, F 1, 21) = 321.8, p <.001, but no Group × Corner interaction (p >.1).
The two-way ANOVA for the time window of 230 270 ms yielded a significant main effect of change type, F 2,24) = 6.766, p = 0.005; both the main effect of electrodes and the interaction between the two were nonsignificant, all ps >0.2.
A Severity×Time ANOVAR yielded a significant Main Effect for Time, as expected, and Mean Effect of Severity (F (1, 44) 39.1, p=0.0001) and a significant interaction of Time and Severity (F (1, 44 =13.8, p=0.001).
Repeated-measures ANOVA yielded a significant main effect of time (P < 0.05), but no significant effect of vector (P = 0.77) nor interaction between vector and time (P = 0.43).
