Children with Rett syndrome manifest profound impairments in their ability to speak and use their hands, and exhibit a very limited repertoire of abilities to express themselves, to be neuropsychologically tested, and consequently to be understood. This study examined nonverbal cognitive abilities and visual preferences by analyzing the pattern of visual fixation in 49 girls with Rett syndrome, compared with a group of typical control subjects. The girls with Rett syndrome demonstrated a tendency toward socially weighted stimuli/social preferences. They looked at people, and into people's eyes. Eye tracking represents a feasible method to assess cognition, and provide insights into the burden of isolation of these children and the mismatch between their social preferences and incompetence, caused by movement disorder and apraxia.
患有雷特综合征的儿童在言语和手部使用能力方面存在严重缺陷，并且在表达自己、接受神经心理测试以及被他人理解方面的能力非常有限。本研究通过分析 49 名雷特综合征女孩的视觉注视模式，与一组典型的对照组进行比较，研究了非言语认知能力和视觉偏好。雷特综合征女孩表现出对社会加权刺激/社会偏好的倾向。她们看着人，看着人的眼睛。眼动追踪是一种评估认知的可行方法，它可以深入了解这些孩子被孤立的负担，以及运动障碍和失用症导致的他们的社会偏好和能力不匹配。
