Mediated models for postural expansiveness, dominance, and romantic attraction (self-reported and receiving a “yes” response from one’s interaction partner). Study 1: Statistics for direct effect (unstandardized betas) are shown above the path and for total indirect effect are shown below the path. Results from Monte Carlo method simulations (resample size = 20,000; see online tool in ref. 42) indicate significant mediation of postural expansiveness on romantic attraction and on getting a “yes” response through perceived dominance, controlling for one’s affiliative displays. The indirect effect of each model is similarly significant when affiliative displays are not included in the model. The Monte Carlo method accounts for repeated assessments of each individual speed-date participant (i.e., within-person variability). **P < 0.01; *P < 0.05.
