To examine whether children with specific language impairment (SLI) differ from normally developing peers in motor skills, especially those skills related to timing.
Standard measures of gross and fine motor development were obtained. Furthermore, finger and hand movements were recorded while children engaged in 4 different timing tasks, including tapping and drawing circles in time with a metronome or a visual target. Fourteen children with SLI (age 6 to 8 years) and 14 age-matched peers who were typically developing participated.
As expected, children with SLI showed poorer performance on a standardized test of gross and fine motor skill than did their normally developing peers. However, timing skill in the manual domain was equivalent to that seen in typically developing children.
Consistent with earlier findings, relatively poor gross and fine motor performance is observed in children with SLI. Surprisingly, rhythmic timing is spared.
探究特定语言障碍（SLI）儿童与正常发育儿童在运动技能方面是否存在差异，尤其是与时间相关的技能。
获取了粗大运动和精细运动发展的标准测量结果。此外，当儿童参与 4 种不同的计时任务（包括用节拍器或视觉目标进行敲击和画圈）时，记录了手指和手部运动。14 名 SLI（6 至 8 岁）儿童和 14 名年龄匹配的正常发育儿童参与了研究。
正如预期的那样，与正常发育的同龄人相比，患有 SLI 的儿童在标准化的粗大运动和精细运动技能测试中表现较差。然而，在手部运动领域的计时技能与正常发育儿童相当。
与早期研究结果一致，患有 SLI 的儿童表现出相对较差的粗大运动和精细运动能力。令人惊讶的是，他们的节奏计时能力并未受到影响。
