Are you a man who grew up in a house full of girls? While it might seem like you'd have some advantages in dating, what with being familiar with the ways of women and all, new research shows that men who grow up with only sisters are viewed as less sexy by other women。

　　Researchers at the University of Texas have just published a study in the journal Psychological Science where they detail their findings on the behavior of rats raised in particular groups. The male rats that were raised solely with female rats - their "sisters" - were found to be less sexually active later on than the male rats that were raised with other male rats。

　　Then researchers found that female rats were less likely to invite sexual activity from the rats that had been raised with many females。

　　The study's author, David Crews, stressed how the study shows the importance of family and that the findings of rat's behavior can be linked to humans as well. "Families are particularly important in shaping personalities. The environment where you were raised doesn't determine personality, but it helps to shape it," he said。

　　你是和众姐妹一起长大的男孩子吗？虽然可能对约会有些好处，可研究发现，像你这样熟悉了女人生活种种的男生，在其他女生眼里，却是没有男性魅力的。

　　美国《时代》周刊24日报道，美国德克萨斯大学的研究人员日前在《心理科学》期刊上发表了一篇研究论文，详细阐述了他们关于在特定群体下成长的小白鼠行为的研究活动。研究人员发现，在日后的交配活动中，被放在雌鼠群体里抚养的雄性小鼠——这些雌鼠相当于他的“姐妹们”——不如那些同雄鼠群体一起长大的雄性小鼠活跃。

　　研究人员还发现雌鼠不太愿意邀请那些在雌鼠群体里长大的雄性小鼠完成交配活动。

　　该研究论文的撰稿人大卫-克鲁斯强调该研究揭示了家庭的重要性和这些鼠类行为的发现对人类的实际意义。“家庭在个性形成方面具有尤其重要的影响。成长的环境虽不决定你的个性，但确是塑造了它，”他说。
