One visual-perceptual test, four visual-motor tests, and a test of motor impairment were administered to 22 children with learning disabilities and 22 children without learning disabilities, aged 5 to 8 years. The children with learning disabilities were divided into two groups--"clumsy" and "nonclumsy"--based on their scores on the motor impairment test. It was hypothesized that the clumsy children with learning disabilities would score significantly lower on visual-perceptual and visual-motor tests than the nonclumsy children with learning disabilities who, in turn, would score significantly lower than the children without learning disabilities. It was further hypothesized that there would be a significant correlation between the degree of clumsiness and the degree of visual-perceptual and visual-motor deficit. Analysis of the data indicated that, as expected, the clumsy children with learning disabilities scored significantly lower than the children without learning disabilities (the control group). There was no significant difference between the clumsy and nonclumsy children with learning disabilities or between the nonclumsy children with learning disabilities and the control group. Degree of clumsiness significantly correlated with scores on four of five tests. Results are discussed in terms of subtypes of learning disabilities and sample size.
对22名患有学习障碍的儿童和22名无学习障碍的5至8岁儿童进行了一项视觉感知测试、四项视觉运动测试以及一项运动障碍测试。根据运动障碍测试的得分,患有学习障碍的儿童被分为两组——“动作笨拙型”和“非动作笨拙型”。研究假设,动作笨拙的学习障碍儿童在视觉感知和视觉运动测试中的得分会显著低于非动作笨拙的学习障碍儿童,而非动作笨拙的学习障碍儿童的得分又会显著低于无学习障碍的儿童。进一步假设,动作笨拙程度与视觉感知和视觉运动缺陷程度之间存在显著相关性。数据分析表明,正如预期的那样,动作笨拙的学习障碍儿童的得分显著低于无学习障碍的儿童(对照组)。动作笨拙的学习障碍儿童与非动作笨拙的学习障碍儿童之间,以及非动作笨拙的学习障碍儿童与对照组之间均无显著差异。动作笨拙程度与五项测试中的四项得分显著相关。研究结果从学习障碍的亚型和样本量方面进行了讨论。
