erences can have large effects. - Why? - Preference mechanisms motivate us to engage in behaviors that tended to increase fitness under the environmental conditions in which they were selected. - Eating ripe fruit supplies our ancestors bodies w/ vital nutrients & calories. - Sexual attracting to sexually mature members of opposite sex increased our ancestors chances of reproducing. - In short, many preferences are present because they increased the probability that their bearers would interact w/ preferred stimulus in ways that tended to increase the distribution of the suite of alleles linked w/ development of that preference. - A main point in this talk: in mating, cues to life stage plays important roles in determining reproductive value - Female Attractiveness & Cues to Mate Value - Cues to sex - Phenotypic quality - Health - Symmetry - Clear skin - Shiny hair - Residual reproductive value - Fertility - Industriousness - Kindness - Trustworthiness - Female beauty & cues of youth linked because residual reproductive value highest @ 1st ovulatory cycle - Evolutionary Mismatches, Byproducts, & Chance - Individuals may be attracted to objects that exhibit cuesCourse Intro (Day 1) 1/11/17 - Associated w/ fitness enhancing properties under ancestral conditions but lack fitness enhancing properties themselves - Individuals may also have preferences for cues that were not under selection per se - Not all interpersonal attraction is sexual - Mate - Offspring - Allies - Alloparents - Friends - Physical Attractiveness for Mating - Fundamental adaptive problem is finding mate who is - Same species - Opposite sex - Reproductive life stage - Fertility & reproductive value - Other important problems - Good genes - Good phenotypic condition - Social / political position & skills - Ability & willingness to invest - Symons says - People don’t come prelabeled - Selection is predicted to result in adaptations associated w/ - High female reproductive value - Particularly if male can monopolize female reproduction - But also because # of fertile days in woman’s life are limited - Peak fertility - Note: Preference for cues of peak residual reproductive value hasn’t seemed to pan out in survey research. - Some of this information can be assessed physically. One cue reproductive value may be waist to hip ratio. - But how does psychology that generates attractiveness assessment come about? And what assessment adaptations do we have?
