在神经发育研究中，整体运动知觉常被用作背视流功能的指标。然而，整体运动知觉与视运动控制（背侧流的主要功能）之间的关系尚不清楚。我们测量了606名出生时有神经发育异常风险的4.5岁儿童的整体运动知觉（运动连贯阈值；MCT）和运动功能标准化测量的表现。视觉敏锐度、立体敏锐度和语言智商也进行了评估。在调整语言智商或视敏度和立体敏度后，MCT与运动功能的所有组成部分都有适度但显著的联系，除了大运动得分。在另一项分析中，立体敏锐度，而不是视觉敏锐度，与粗大和精细运动得分都有显著关联。这些结果表明，运动知觉和立体视觉的发展与学龄前儿童的运动功能有关。
Global motion perception is often used as an index of dorsal visual stream function in neurodevelopmental studies. However, the relationship between global motion perception and visuomotor control, a primary function of the dorsal stream, is unclear. We measured global motion perception (motion coherence threshold; MCT) and performance on standardized measures of motor function in 606 4.5-year-old children born at risk of abnormal neurodevelopment. Visual acuity, stereoacuity and verbal IQ were also assessed. After adjustment for verbal IQ or both visual acuity and stereoacuity, MCT was modestly, but significantly, associated with all components of motor function with the exception of gross motor scores. In a separate analysis, stereoacuity, but not visual acuity, was significantly associated with both gross and fine motor scores. These results indicate that the development of motion perception and stereoacuity are associated with motor function in pre-school children.
