Mediated moderation models examining mediational pathways that differ according to number of group members smiling explaining alcohol reward-sensitivity among extraverted individuals

All variables are centered. Gender is coded such that Male = −.5 and Female = .5 and Alcohol is coded such that No Alcohol= −.5 and Alcohol = .5.

Simultaneous smiling = target group member smiles simultaneously with either one or two other group members; Unilateral smiling = only target group member smiling; Dyadic smiling = target group member smiles simultaneously with one other group member; Golden moments = target group member smiles along with both other group members.

^*Coefficient represents the mediated moderation effect of interest in the present research

⁺The overall moderating effect of extraversion on alcohol response (Extraversion X Alcohol) is significant, p = 0.0215, when the mediated moderational pathway is not included in the model.
