背侧视觉处理流包括V1、运动敏感区V5和后顶叶，支持视觉引导的运动功能。最近的两项研究报告了整体运动知觉（V5处理的行为测量）与学龄前和学龄儿童运动功能之间的关联。这表明了视觉和运动发育之间的关系，也支持使用整体运动知觉来评估人类神经发育研究中的整体背流功能。我们调查了视力和运动功能之间的联系是否存在于2岁时，这是一个相当早期的发展阶段。对404名2岁（± 4周）儿童进行了Bayley III婴幼儿发育测试和视力测量，包括视力（卡迪夫视力卡）、立体视（Lang立体测试）和整体运动知觉。通过观察视动性眼球震颤对不同相干性的随机点运动图的反应来评估整体运动感知（量化为运动相干性阈值）。线性回归显示，整体运动知觉是适度的，但在统计学上与Bayley III复合运动（r2 = 0.06，p < 0.001，n = 375）和粗大运动评分（r2 = 0.06，p < 0.001，n = 375）显著相关。当语言成绩被纳入回归模型时，这种关联仍然显着。此外，当模型中包含语言评分时，立体视觉与综合运动和精细运动评分显着相关，但裸眼视力与任何运动评分均无统计学显着相关。这些结果表明，整体运动知觉和双眼视觉与运动功能在早期发展阶段。整体运动知觉可以作为一个部分措施的背流功能从幼儿期。
The dorsal visual processing stream that includes V1, motion sensitive area V5 and the posterior parietal lobe, supports visually guided motor function. Two recent studies have reported associations between global motion perception, a behavioural measure of processing in V5, and motor function in pre-school and school aged children. This indicates a relationship between visual and motor development and also supports the use of global motion perception to assess overall dorsal stream function in studies of human neurodevelopment. We investigated whether associations between vision and motor function were present at 2 years of age, a substantially earlier stage of development. The Bayley III test of Infant and Toddler Development and measures of vision including visual acuity (Cardiff Acuity Cards), stereopsis (Lang stereotest) and global motion perception were attempted in 404 2-year-old children (± 4 weeks). Global motion perception (quantified as a motion coherence threshold) was assessed by observing optokinetic nystagmus in response to random dot kinematograms of varying coherence. Linear regression revealed that global motion perception was modestly, but statistically significantly associated with Bayley III composite motor (r2 = 0.06, p < 0.001, n = 375) and gross motor scores (r2 = 0.06, p < 0.001, n = 375). The associations remained significant when language score was included in the regression model. In addition, when language score was included in the model, stereopsis was significantly associated with composite motor and fine motor scores, but unaided visual acuity was not statistically significantly associated with any of the motor scores. These results demonstrate that global motion perception and binocular vision are associated with motor function at an early stage of development. Global motion perception can be used as a partial measure of dorsal stream function from early childhood.
