基于有一个年长的兄弟姐妹被诊断为自闭症谱系障碍(ASD)，为了探索自闭症谱系障碍(ASD)的高风险如何影响单词理解和语言处理速度，在一项横断面研究中，对18个月、24个月和36个月大的高风险和低风险ASD儿童进行了一项横断面研究，测试了接受语言的眼睛凝视测量，以衡量儿童观看命名目标图像的准确性和速度。18个月和24个月龄的高危ASD组和低危对照组之间无显著差异。然而，在ASD高危人群中，36个月大的婴儿在准确性测量上表现明显较差，但在速度测量上没有表现。我们认为，高危人群的语言加工效率没有受到影响，但其他词汇习得因素可能导致了高危36月龄婴儿在我们的测量中理解的名词明显减少。
To explore how being at high risk for autism spectrum disorder (ASD), based on having an older sibling diagnosed with ASD, affects word comprehension and language processing speed, 18-, 24- and 36-month-old children, at high and low risk for ASD were tested in a cross- sectional study, on an eye gaze measure of receptive language that measured how accurately and rapidly the children looked at named target images. There were no significant differences between the high risk ASD group and the low risk control group of 18- and 24-month-olds. However, 36-month-olds in the high risk for ASD group performed significantly worse on the accuracy measure, but not on the speed measure. We propose that the language processing efficiency of the high risk group is not compromised, but other vocabulary acquisition factors might have lead to the high risk 36-month-olds to comprehend significantly fewer nouns on our measure.
