Shaping men's memory: the effects of a female's waist-to-hip ratio on men's memory for her appearance and biographical information

Previous research has shown that people are better at remembering attractive faces than unattractive faces, possibly because physical attractiveness is a sign of increased mate value. However, perceivers may rely on additional appearance cues (e.g., bodily features, dress) when assessing mate value. Thus, men may remember more about a female target when she possesses more attractive bodily features, such as a waist-to-hip ratio that approaches the optimal .70. Two studies were conducted to examine whether female waist-to-hip ratio influences the number of details men recall and recognize about a female target. Study 1 utilized a free recall method, whereas Study 2 consisted of a recognition method. Results indicated that men who viewed a female target with a waist-to-hip ratio of .50 or .90 recalled and recognized significantly fewer details than men who viewed a female target with a waist-to-hip ratio of .60, .70, or .80. These data illustrate adaptive memory, whereby perceivers better remember information of greater adaptive value to them, because this information may lead them to make better fitness-related decisions about whom to potentially mate with. Limitations regarding the realism of the photographs and generalizability of the data are also discussed.
