背景：社交焦虑障碍（SAD）是一种典型的儿童期和青少年期起病的疾病。社会信息的不适应性处理可能有助于SAD的病因和维持。在人脸感知过程中，个体执行一系列视觉注视，称为扫描路径，这有助于信息处理。非典型的长扫描路径已报告在成人SAD，但没有数据存在从儿科样本。SAD也与面部感知过程中的非典型唤醒有关。这两个指标都在迄今为止最大的儿童SAD眼动追踪研究中进行了检查。研究方法：参与者是SAD儿童和青少年（n = 61）和健康对照组（n = 39），平均年龄为14岁（范围10 - 17），他们完成了情绪识别任务。使用眼动追踪检查视觉扫描路径和瞳孔扩张（唤醒的间接指标）。结果：青年SAD患者扫描路径短，分布少，注视次数少。这些发现得到了频率论和贝叶斯统计的支持。在SAD组中也观察到更高的瞳孔扩张，但尽管存在统计学显著性组间差异，但贝叶斯分析不支持该结果。结论：结果与成人研究的结果相反，但与与社会互动障碍相关的神经发育状况报告相似。受限的扫描路径可能会破坏已知有利于适应性社会理解的面部整体表征。
Background: Social anxiety disorder (SAD) has its typical onset in childhood and adolescence. Maladaptive processing of social information may contribute to the etiology and maintenance of SAD. During face perception, individuals execute a succession of visual fixations known as a scanpath which facilitates information processing. Atypically long scanpaths have been reported in adults with SAD, but no data exists from pediatric samples. SAD has also been linked to atypical arousal during face perception. Both metrics were examined in one of the largest eye-tracking studies of pediatric SAD to date. Methods: Participants were children and adolescents with SAD (n = 61) and healthy controls (n = 39) with a mean age of 14 years (range 10–17) who completed an emotion recognition task. The visual scanpath and pupil dilation (an indirect index of arousal) were examined using eye tracking. Results: Scanpaths of youth with SAD were shorter, less distributed, and consisted of a smaller number of fixations than those of healthy controls. These findings were supported by both frequentist and Bayesian statistics. Higher pupil dilation was also observed in the SAD group, but despite a statistically significant group difference, this result was not supported by the Bayesian analysis. Conclusions: The results were contrary to findings from adult studies, but similar to what has been reported in neurodevelopmental conditions associated with social interaction impairments. Restricted scanpaths may disrupt holistic representation of faces known to favor adaptive social understanding.
