positive affect factor of the PANAS. Additionally, there
were no group differences in reported in any variable, with
the exception of the arousal ratings during the control
condition. During the no-shock control condition the RHD
and LHD groups reported significantly less arousal than the
LH NCS, but not the RH NCS.
Reward condition
Positive and negative affect schedule. Repeated
measures analyses of variance (ANOVAs) were used to explore
positive affect factor (PA) and negative affect factor (NA)
for the reward conditions. The between subject factor was
group (LHD, LH NCS, RHD, RH NCS) and the within subject
factor was condition (reward, no-reward control). Results
revealed that there was a significant main effect of
condition for PA [F(l,44) = 7.52 P < .01]. The mean score
was 33.38 for the reward trial and 30.26 for the control
trial indicating that subjects reported more positive affect
during the reward compared to the reward-control trial.
Examination of means revealed no significant main effects or
interaction were found for NA. These two ANOVA tables,
Table C-77 and C-78, are presented in Appendix C.
Self-assessment manikin. Valence, arousal, and
dominance ratings were analyzed using Wilcoxon and Kruskal-
Wallis Tests. Examination of the verbal report ratings of
valence, arousal, and dominance during the reward and
reward-control trials revealed a main effect for trial for
