%0 Journal Article %T A Research Note on the Influence of Relationship Length and Sex on Preferences for Altruistic and Cooperative Mates %A Ken Manktelow %A Manpal Singh Bhogal %A Niall Galbraith %J Psychological Reports %@ 1558-691X %D 2019 %R 10.1177/0033294118764640 %X Previous literature suggests that altruism may have evolved as a sexually selectable trait. Recent research suggests that women seek altruistic traits for long-term, not short-term relationships, as altruism can serve as an honest signal of one¡¯s character. We tested this hypothesis by asking 102 participants to complete a modified version of Buss¡¯s Mate Preferences Questionnaire. We found that women placed higher importance on altruism in a mate compared to men, and this preference was greater when seeking a long-term mate, compared to a short-term mate. We also found that although women placed greater importance on cooperativeness in a mate compared to men, this preference was not influenced by whether they were seeking a short-term or a long-term mate. We successfully replicate previous literature exploring the role of altruism in mate choice %K Altruism %K cooperation %K sexual selection %K mate choice %K mate preferences %K prosocial behaviour %U https://journals.sagepub.com/doi/full/10.1177/0033294118764640
