Bottom Line: Heightened emotional reactivity may have driven AD to punish the proposer rather than acting as a rational economic agent.An implication of present findings is that AD might have difficult to cope with unfair situations triggered by social interactions.Future studies are needed in order to examine whether-emotional and behavioral-reactivity to unfairness during the UG could impact alcohol consumption and relapse in AD.

ABSTRACT
Recent empirical findings suggest that alcohol dependence is characterized by heightened sensitivity to unfairness during social transactions. The present study went a step further and aimed to ascertain whether this abnormal level of sensitivity to unfairness is underlined by an increased emotional reactivity. Twenty-six recently abstinent alcohol-dependent (AD) individuals and 32 controls performed an ultimatum game (UG), in which participants had to respond to take-it-or-leave-it offers, ranging from fair to unfair and made by a fictive proposer. Emotional state was recorded during UG offers presentation and was indexed by the amplitude of skin conductance response (SCR). Results showed that AD decided to reject unfair offers more frequently than their controls, confirming previous data. The proportion of rejected unfair UG offers was correlated with SCR, in the AD but not in the control group. This finding suggests that deciding to accept or reject unfair UG offers is influenced by arousal-affective activity in AD, but not in controls. Heightened emotional reactivity may have driven AD to punish the proposer rather than acting as a rational economic agent. An implication of present findings is that AD might have difficult to cope with unfair situations triggered by social interactions. Future studies are needed in order to examine whether-emotional and behavioral-reactivity to unfairness during the UG could impact alcohol consumption and relapse in AD.

In the alcohol-dependent group (n = 26), proportion of accepted unfair offers was negatively correlated with SCR amplitude triggered by unfair offers (Spearman Rho = –0.41, p = 0.04).

Figure 2: In the alcohol-dependent group (n = 26), proportion of accepted unfair offers was negatively correlated with SCR amplitude triggered by unfair offers (Spearman Rho = –0.41, p = 0.04).

Mentions: A Friedman test was performed separately in each group in order to examine the effect of the type of offers (fair vs. medium-fair vs. unfair) on SCR (in mS). These analyses showed no significant SCR differences, in each group (all p > 0.05), between the fair (control group: mean = 0.315, median = 0.254, 25th = 0.09, 75th = 0.42; alcohol group: mean = 0.41, median = 0.33, 25th = 0.138, 75th = 0.583), the medium-fair (control group: mean = 0.296, median = 0.18, 25th = 0.10, 75th = 0.47; alcohol group: mean = 0.288, median = 0.19, 25th = 0.008, 75th = 0.413) and the unfair offers (control group: mean = 0.292, median = 0.33, 25th = 0.071, 75th = 0.45; alcohol group: mean = 0.41, median = 0.33, 25th = 0.138, 75th = 0.583). We then performed correlation analyses (Spearman Rho) between SCR and proportion of acceptance, for each types of offer and each group separately. These analyses showed that, in the alcohol dependence group, proportion of acceptance is negatively correlated with SCR for the unfair offers (Spearman Rho = –0.41, p = 0.04; see Figure 2). This association did not reach significance in the control group. We observed no significant correlation for the fair and medium fair offers, in both control and AD groups.
