People start stereotyping early. Even toddlers react positively to members of their own race, but often distrust those from different groups. ___1___ are planted in most everyone. Everyone, that is, except people with a rare genetic condition called Williams syndrome.
Williams syndrome ___2___ heart defects, mental retardation, and a lack of social anxiety that produces exceedingly friendly human beings. And a new study published in the journal Current Biology finds that children with Williams syndrome ___3___.
Researchers re-did previous social-bias experiments on 20 children with Williams syndrome and 20 control kids. The children viewed pictures of people of ___4___ races and genders and assigned negative or positive storylines to each picture. True to form, the control group preferred their own race and gender. The children with Williams syndrome, however, had no racial preference—although they still discriminated by gender.
The results imply a nuanced neural mechanism to stereotyping, the further study of which quote“may suggest ways of reducing ___5___ towards vulnerable or marginalized groups.”

偏见自小就有，就算是踉跄学步的小孩子也是对自己种族的人比较亲昵，而对其他种族的人往往保持距离。几乎每一个人身上都有种族偏见的种子在萌芽，不过患有罕见的威廉斯综合症的人们就另当别论了。 威廉斯综合症的特征是：心脏、智力存在缺陷，因缺乏社交焦虑而过分友好。《当代生物学》中的一项新研究发现，威廉斯综合症患儿无种族偏见。 研究人员再一次在20名威廉斯综合症患儿身上进行了一次测试社交偏见的实验，并以另外20名正常儿童作为对照组。研究人员让孩子们看各种族、不同性别人的照片，并让他们给每张照片上的人编一段故事。对照组的孩子们一如既往地偏爱和自己同一种族、同一性别的人，而威廉斯综合症患儿尽管仍有性别偏好，但却没有种族偏好。 研究结果显示出微妙的神经机制对偏见的影响，对偏见的进一步研究“很有可能有助于减少对弱势、边缘群体的偏激举动”。
