symmetrical features are an 'honest' signal of strong, healthy genes which we desire in our partner as an attractive partner should produce attractive, healthy offspring who will survive + reproduce successfully
they trigger a caring response from the partner neotenous features are characteristic of young children + trigger development of the attachment bond in parents & children females who want to reproduce sneed to be cared for during pregnancy/birth females with features that trigger the caring response reproduce most successfully
give a strength of evolutionary explanations in physical attractiveness
:) valid explanations - neotenous features are consistent across cultures so preference is decided by natural selection - Cunningham et al found female features like large eyes, prominent cheekbones and high eyebrows rated as attractive by white, Hispanic and Asian males
genetically programmed to desire the most attractive partner but there are few highly attractive people + they'll be in high demand so unless we're also highly attractive, very attractive people are likely to reject us necessary to make a compromise and balance our genetically programmed desire with fear of rejectionwe judge our own level of attractiveness + settle for someone with the same level
:) importance of physical attractiveness in interpersonal attraction supported by research evidence e.g. Feingold et al - did meta-analysis of 17 studies - found significant correlation in attractiveness between romantic partners - study has high ecological validity as it assessed actual partners - matching hypothesis is a valid explanation
:( Feingold et al research is correlational so cause and effect can't be established - effect may be other way around e.g. people become more similar when spending lots of time together (similar diet, similar value to personal grooming) - hypothesis isn't properly validated as the explanation is weak :( research has failed to confirm predictions of the matching hypothesis e.g. Taylor et al studied activity on an online dating agency - found participants sought dates with most attractive partners, irrespective of their own attractiveness - study has high ecological validity as it looked at actual choices - matching hypothesis is likely an invalid explanation
