不分青红皂白的社会接近行为是威廉姆斯综合征(WS)行为表型的一个显著特征。本研究考察了患有WS的学龄前儿童的接近行为，并评估了面孔在WS社会接近行为中的作用。方法10名WS学龄前儿童(3-6岁)和两组典型发育儿童，在时间或心理年龄上与WS组相匹配，参加了观察到的游戏课程。游戏会话包括社交和非社交两个部分，包括评估对陌生人的接近行为的两个部分；一个是可以看到陌生人的脸，另一个是陌生人的脸被遮盖。结果在游戏会话的非社交方面，WS组的行为与两个对照组相似。相比之下，患有WS的学龄前儿童明显比对照组更愿意与陌生人打交道，即使在看不到陌生人的脸的情况下也是如此。结论这一发现挑战了这样的假设，即对面孔的异常吸引力直接激发了WS患者的社交行为。
BackgroundIndiscriminate social approach behaviour is a salient aspect of the Williams syndrome (WS) behavioural phenotype. The present study examines approach behaviour in pre-schoolers with WS and evaluates the role of the face in WS social approach behaviour.MethodTen pre-schoolers with WS (aged 3-6 years) and two groups of typically developing children, matched to the WS group on chronological or mental age, participated in an observed play session. The play session incorporated social and non-social components including two components that assessed approach behaviour towards strangers; one in which the stranger's face could be seen and one in which the stranger's face was covered.ResultsIn response to the non-social aspects of the play session, the WS group behaved similarly to both control groups. In contrast, the pre-schoolers with WS were significantly more willing than either control group to engage with a stranger, even when the stranger's face could not be seen.ConclusionThe findings challenge the hypothesis that an unusual attraction to the face directly motivates social approach behaviour in individuals with WS.
