The purpose of the current study was to assess meaningful variability in visual-perceptual skills using a standardized assessment of visual perception, the Test of Visual Perceptual Skills (TVPS), across children with and without autism spectrum disorder (ASD). In addition to assessing overall accuracy across subtests of the TVPS, we also assessed response variability at the item-level, and the linear relationship between quantitative measures of ASD symptoms, task performance, and item-level variance. We report a significant linear relationship between ASD features and performance on the TVPS Figure Ground subtest. Additionally, results of an item-level analysis point to a significant relationship between within-task variability on the Figure Ground subtest and quantitative ASD traits, with a less variable response pattern being associated with increased ASD symptoms. Findings presented here suggest variability in perceptual processing across ASD may be influenced by individual differences in trait distribution.

自闭症谱系障碍视觉感知技能的综合评估。

本研究的目的是使用标准化的视觉感知评估，即视觉感知技能测试 (TVPS)，在患有和不患有自闭症谱系障碍 (ASD) 的儿童中评估视觉感知技能的有意义的变化。除了评估 TVPS 子测试的整体准确性外，我们还评估了项目级别的反应变异性，以及 ASD 症状的定量测量、任务表现和项目级别方差之间的线性关系。我们在 TVPS Figure Ground 子测试中报告了 ASD 特征和性能之间的显着线性关系。此外，项目级分析的结果表明，Figure Ground 子测试的任务内可变性与定量 ASD 特征之间存在显着关系，与 ASD 症状增加相关的反应模式变化较小。此处提出的研究结果表明，ASD 感知处理的变异性可能受到性状分布的个体差异的影响。
