Individuals with Williams syndrome (WS) are well known for their friendly behaviour and tendency to approach strangers indiscriminately as if everybody were their friend. This tendency to approach strangers is mirrored in their ratings of unfamiliar face stimuli. Here we examined their perception of unfamiliar expressive faces and found that individuals with WS do not always see faces as being highly approachable. Happy faces were rated as more approachable by individuals with WS than by controls. In contrast, the other less approachable face stimuli were rated lower on approachability by individuals with WS than by controls. Thus, it appears that although individuals with WS will discriminate people in terms of approachability, they have difficulty inhibiting their strong compulsion towards social interaction. The form of this strong pro-social compulsion is discussed both in terms of friendliness and in terms of the heightened salience of social stimuli (social stimulus attraction).
患有威廉姆斯综合征（WS）的个体以其友好行为以及不分青红皂白地接近陌生人的倾向而闻名，就好像每个人都是他们的朋友一样。这种接近陌生人的倾向在他们对陌生面孔刺激的评分中也有所体现。在此，我们研究了他们对陌生表情面孔的感知，发现患有WS的个体并不总是将面孔视为非常容易接近的。与对照组相比，患有WS的个体对笑脸的可接近性评分更高。相反，其他不太容易接近的面孔刺激，患有WS的个体对其可接近性的评分低于对照组。因此，尽管患有WS的个体能够根据可接近性来区分他人，但他们难以抑制对社交互动的强烈冲动。这种强烈的亲社会冲动的形式将从友好性以及社会刺激（社会刺激吸引力）的高度显著性这两个方面进行讨论。
