Men and women have distinct preferences for certain traits in their romantic partners, which can

be elegantly explained by evolutionary theories of sexual selection. Specifically, men and

women highly value the mate characteristics of warmth, attractiveness, and resources in a

relationship partner, which all enhance their reproductive fitness. By manipulating different

combinations of these attributes, the current research aimed to examine thresholds of acceptance

and desirability in different temporal relationship contexts. It also explored the effect of a

previously unexplored cue to health, a physical disability, on mating preferences. In Study One,

568 participants were shown a photograph of a stimulus person, either with or without a

physical disability, paired with manipulated descriptions of economic status and warmth. They

were asked to indicate their willingness to engage in both a short-term and long-term

relationship with the individual in the vignette, as well as complete questionnaires on

sociosexuality and social desirability. The results showed the importance of warmth in the longterm

for both men and women, the value of economic status for women in the long-term, the

significance of health on short-term relationships, and predicted individual variations according

to sociosexual orientation. However, when the effects of social desirability were taken into

consideration, health was not found to have an effect on the reported desirability of short-term

relationships. Study Two used a slightly different methodology to replicate the findings from

Study One with a different sample of 566 participants, and explored the impact of heritability on

both short-term and long-term relationship preferences. The results from Study Two generally

replicated the results from Study One, with the exception of health. The impact of a physical

disability, whether inherited or not, was not found to be significant in Study Two, nor did social

desirability. By exploring the evolutionary logic behind disability-based prejudice in

relationships, the current studies aimed to contribute to the existing knowledge on mate

preferences and deepen our understanding about the contemporary negative attitudes towards

relationships with individuals with disabilities.
