The Environmental Security Hypothesis (ESH) proposes that when the environment is less secure, people will show greater preference for mates with survival-promoting traits (Pettijohn and Jungeberg in Personality and Social Psychology Bulletin, 30(9), 1186–1197, 2004). In this study, we manipulated perceived environmental security and measured preference for different body and face characteristics as well as attitudes toward long-term (LTM) and short-term mating (STM) strategies. Participants (N = 100) received a cover story designed to lead experimental, but not control, participants to believe they would be required to handle a poisonous snake. Participants then completed a measure of sociosexual orientation and selected the three opposite-sex face and body types that they found most attractive from image matrices depicting physical characteristics varying systematically across body and face shape. Female bodies varied in body fat and waist-to-hip ratio, and male bodies varied in muscle mass and waist-to-chest ratio. Face stimuli varied in masculine–feminine facial shape and masculine–feminine facial coloration. Results indicated that, compared to controls, men in the environmental-threat condition showed a preference for higher body fat, and women in the environmental-threat condition showed a preference for higher muscle mass and more masculine faces. These women also showed a more positive attitude toward STM, but not LTM. In line with the ESH, our findings predominantly support a context-specific pattern of mate preference and sexual strategies.
