摘要: 了解任务难度对发展性阅读障碍儿童执行功能的影响，为改善儿童执行功能状况提供参考。采用儿童HR神经心理成套测验中的连线测验，对22名阅读障碍儿童和21名正常儿童进行测试。在完成时间上，任务难度(F = 14.95, p = 0.001)和组别(F = 6.69, p = 0.014)主效应、任务难度 × 组别的交互效应(F = 8.33, p = 0.006)均差异显著；在完成错误数上，除任务难度主效应(F = 14.95, p = 0.001)差异显著外，其余差异均不显著；在干扰量上，阅读障碍组结果明显大于正常对照组，二者差异显著(t = 2.87, p = 0.006)。任务难度不仅影响阅读障碍儿童的执行功能，而且对他们的活动效果带来不利作用。
Abstract: To investigate the influence of task difficulty on the executive functions of children with developmental dyslexia and improve the executive function of children, 22 children with developmental dyslexia and 21 normal children were tested with TMT in children’s HR neuropsychological test. The main effect of task difficulty (F = 14.95, p = 0.001) and group (F = 6.69, p = 0.014), and the interaction effect of task difficulty × Group (F = 8.33, p = 0.006) were significantly different in the completion time. At the same time, there was no significantly difference in the number of errors except the main effect of task difficulty (F = 14.95, p = 0.001). In the quantity of interference, the dyslexic group significantly higher than the normal control group, the score had significant difference (t = 2.87, p = 0.006). The task difficulty not only affects the execution function of children with dyslexia, but also has a negative effect on their activity.
