非典型视觉知觉在自闭症谱系障碍(ASD)患者中的描述越来越多，并与没有自闭症谱系障碍的儿童和成人中存在的量化的自闭症样特征有关。我们在具有一系列临床特征的儿科样本中调查了视觉处理技能的个体差异是否与自闭症特征的量化测量有关。使用视觉感知技能测试(TVPS)来全面表征视觉处理，TVPS是一种标准化的视觉感知测试，有七个分测试，涵盖了一系列视觉处理能力。TVPS图形背景(TVPS-FG)子测试要求个体从较大的场景中取出较小的图形。TVPS-FG分测验分数与儿童自闭症症状问卷(BAP-Q)的父母报告所测量的自闭症特征呈正相关。与BAP-Q的相关性仅限于TVPS-FG分测验，其他TVPS分测验得分与BAP-Q无显著相关。这增加了越来越多的研究，证明非典型视觉处理与自闭症表型有关，并突显了在异质性发育性大脑疾病中捕获数量特征的重要性。
Atypical visual perception has increasingly been described in individuals with autism spectrum disorders (ASD) and linked to quantitative, autism-like features that are present in children and adults without ASD. We investigated whether individual differences in visual processing skills were related to quantitative measures of autism traits in a pediatric sample with a range of clinical features. Visual processing was comprehensively characterized using the test of visual perceptual skills (TVPS), a standardized test of visual perception with seven subtests that capture a range of visual processing abilities. The TVPS Figure Ground (TVPS-FG) subtest requires an individual to disembed a smaller figure from a larger scene. TVPS-FG subtest scores were positively correlated with children's autism features as measured by a parental report of the Broader Autism Phenotype Questionnaire (BAP-Q). The correlation with BAP-Q was specific to the TVPS-FG subtest, as the other TVPS subtest scores were not significantly related to the BAP-Q. This adds to the growing body of research documenting that atypical visual processing is associated with the autism phenotype and highlights the importance of capturing quantitative traits in heterogeneous developmental brain disorders.
