The main aim of this review is to evaluate the proposal that several developmental disorders affecting vision share an impairment of the dorsal visual stream. First, the current definitions and common measurement approaches used to assess differences in both local and global functioning within the visual system are considered. Next, studies assessing local and global processing in the dorsal and ventral visual pathways are reviewed for five developmental conditions for which early to mid level visual abilities have been assessed: developmental dyslexia, autism spectrum disorders, developmental dyspraxia, Williams syndrome and Fragile X syndrome. The reviewed evidence is broadly consistent with the idea that the dorsal visual stream is affected in developmental disorders. However, the potential for a unique profile of visual abilities that distinguish some of the conditions is posited, given that for some of these disorders ventral stream deficits have also been found. We conclude with ideas regarding future directions for the study of visual perception in children with developmental disorders using psychophysical measures.
本次综述的主要目的在于评估以下观点，即几种影响视觉的发育障碍存在背侧视觉流损伤。首先，我们考虑了当前用于评估视觉系统内局部和整体功能差异的定义和常见测量方法。接下来，我们针对以下五种发育障碍疾病，评估了评估早期到中期视觉能力的背侧和腹侧视觉通路的局部和整体处理情况：发育性阅读障碍、自闭症谱系障碍、发育性运动障碍、威廉姆斯综合征和脆性 X 综合征。综述证据广泛支持这样一种观点，即背侧视觉流在发育障碍中受到影响。然而，鉴于某些情况下也发现了腹侧流缺陷，因此我们假设存在可区分某些病症的独特视觉能力特征。最后，我们提出了使用心理物理学测量方法研究发育障碍儿童视觉感知的未来方向的想法。
