Do impressions of health, dominance, and warmth explain why masculine faces are preferred more in a short-term mate?

From the book : Evolutionary Psychology 5 issue 1 : 15-27.
Men high in facial masculinity are preferred more as a short-term partner (STP) than a long-term partner (LTP).
We used a representative sample of natural faces to examine whether the greater preference for masculine-looking men as a STP could be explained by the fact that they look healthier, more dominant, or lower in warmth.
None of these attributes explained the greater preference for facial masculinity in a STP.
Rather, masculinity mediated the greater preference for healthy and dominant looking men as a STP.
Women also preferred men who appeared high in warmth more as a LTP than a STP, an effect independent of facial masculinity, but mediated by facial expression.
Our results suggest that women do not prefer masculine- looking men more as a STP than a LTP simply because they look healthier, more dominant, or less warm.
