Neural mediators of attraction, acceptance, and rejection
Researchers from the University of Minnesota are reporting at the June meeting of the Organization for Human Brain Mapping that an attractive woman’s acceptance of a date with a male participant makes her appear more physically attractive to him and increases his brain activity in areas associated with reward or positive feelings. This does not occur if the woman is rejecting or unattractive. This finding provides new insights into how the male brain combines information about a woman’s physical attractiveness and the woman’s acceptance of him to influence his perceptions of her (further work is necessary to determine whether a similar effect occurs in women). more
