The aim of our study was to compare two neurodevelopmental disorders (Williams syndrome and autism) in terms of the ability to recognize emotional and nonemotional facial expressions. The comparison of these two disorders is particularly relevant to the investigation of face processing and should contribute to a better understanding of social behaviour and social cognition. Twelve participants with WS (from 6;1 to 15 years) and twelve participants with autism (from 4;9 to 8 years) were matched on verbal mental age. Their performances were compared with those of twelve typically developing controls matched on verbal mental age (from 3;1 to 9;2). A set of five tasks assessing different dimensions of emotional and nonemotional facial recognition were administered. Results indicated that recognition of emotional facial expressions is more impaired in Williams syndrome than in autism. Our study comparing Williams syndrome and autism over a small age range highlighted two distinct profiles which call into question the relationships between social behaviour/cognition and emotion perception.
我们研究的目的是比较两种神经发育障碍（威廉姆斯综合征和自闭症）在识别情感和非情感面部表情方面的能力。这两种障碍的比较对于面部加工的研究尤为重要，并且应该有助于更好地理解社会行为和社会认知。12名威廉姆斯综合征患者（年龄从6岁1个月到15岁）和12名自闭症患者（年龄从4岁9个月到8岁）在言语心理年龄上进行了匹配。他们的表现与12名在言语心理年龄上匹配的典型发育对照组（年龄从3岁1个月到9岁2个月）的表现进行了比较。实施了一组五项任务，以评估情感和非情感面部识别的不同维度。结果表明，威廉姆斯综合征患者在识别情感面部表情方面比自闭症患者受损更严重。我们在较小年龄范围内比较威廉姆斯综合征和自闭症的研究突出了两种不同的特征，这对社会行为/认知与情感感知之间的关系提出了质疑。
