Information on personality was found to significantly change the probability，showing that cognitive(认知的) processes modify(修改) judgments of attractiveness.“Thinking a person as having a desirable personality makes the person more suitable in general as a close relationship partner of any kind，” said Lewandowski.The findings show that a positive personality leads to greater expectation of being friends，which leads to greater expectation of being romantic partners and，finally，to being viewed as more physically attractive.
