目标。本研究调查了书写速度慢和正常的儿童在知觉运动测量和持续注意力方面的差异以及这些因素之间的关系。方法。台湾小学的 34 名慢速手写者和 35 名正常速手写者（7 至 11 岁）接受了三项知觉运动测试和一项评估持续注意力的警惕任务。使用多元方差分析和回归分析来分析这些措施的表现。结果。慢速书写者和正常书写者在上肢协调性、视觉记忆空间关系、形式恒定性视觉顺序记忆、图形背景、视觉运动整合和持续注意力方面存在显着差异。对于慢速书写者来说，预测书写速度的三个重要因素是年龄、视觉顺序记忆和视觉运动整合。对于正常速度的书写者来说，年龄、上肢速度和灵巧度是仅有的两个显着的预测因素。结论。慢速和正常速度的手写者通过不同的感知运动系统来响应手写需求。虽然拉链肢的速度和灵活性似乎在正常速度的手写体中发挥着重要作用，但慢速的手写体似乎更多地依赖于视觉引导过程，包括序列记忆和视觉运动整合。
Objectives. This study investigated differences in perceptual-motor measures and sustained attention between children with slow and normal handwriting speed and the relationship between these factors.Method. Thirty-four slow handwriters and 35 normal speed handwriters (7 to 11 years of age) attending elementary schools in Taiwan were given three perceptual-motor tests and a vigilance task to assess sustained attention. Performances on these measures were analyzed using multivariate analysis of variance and regression analyses.Results. A significant difference was found between slow and normal handwriters in upper-limb coordination, visual memory spatial relation, form constancy visual sequential memory, figure ground, visual-motor integration, and sustained attention. The three significant predictors of handwriting speed for the slow handwriters were age, visual sequential memory, and visual-motor integration. For the normal speed handwriters, age and upper-limb speed and dexterity were the only two significant predictors.Conclusions. Slow and normal speed handwriters responded to handwriting demands through different perceptual-motor systems. Whereas zipper-limb speed and dexterity seems to play an important role in normal speed handwriters, slow handwriters seem to rely more on visually directed processes, including sequence memory and visual-motor integration.
