Deficits in perceptual constancies from early infancy have been proposed to contribute to autism and exacerbate its symptoms (Hellendoorn et al., Frontiers in Psychology 6:1-16, 2015). Here, we examined size constancy in adults from the general population (N = 106) with different levels of self-reported autistic traits using an approach based on negative afterimages. The afterimage strength, as indexed by duration and vividness, was also quantified. In opposition to the Hellendoorn and colleagues' model, we were unable to demonstrate any kind of relationship between abilities in size constancy and autistic traits. However, our results demonstrated that individuals with higher degrees of autistic traits experienced more persistent afterimages. We discuss possible retinal and post-retinal explanations for prolonged afterimages in people with higher levels of autistic traits.
婴幼儿期早期感知恒常性的缺陷被认为与自闭症有关，并会加重其症状（海伦多恩等人，《心理学前沿》6:1 - 16，2015年）。在此，我们使用基于负后像的方法，对来自普通人群的106名具有不同自我报告自闭症特征水平的成年人的大小恒常性进行了研究。同时，还对以持续时间和生动程度为指标的后像强度进行了量化。与海伦多恩及其同事的模型相反，我们未能证明大小恒常性能力与自闭症特征之间存在任何形式的关系。然而，我们的结果表明，自闭症特征程度较高的个体经历的后像持续时间更长。我们讨论了自闭症特征水平较高的人后像延长的可能视网膜及视网膜后解释。
