注意缺陷多动障碍患儿生物运动感知能力的研究

目的 探讨注意缺陷多动障碍(ADHD)患儿生物运动感知能力.方法 采用时距辨别任务对46例ADHD患儿和46例健康对照组进行生物运动感知能力测试.结果 健康对照组的主观相等点(PSE)(-0. 30 ± 0. 35)为负值,与检验值"0"比较,差异有统计学意义(t=-5. 83,P<0.05).与健康对照组的PSE相比,ADHD患儿的PSE(0.06 ±0. 63)为正值,且明显增大,差异有统计学意义(0=0. 34, P<0. 05) . Pearson相关分析显示,ADHD患儿的生物运动感知能力与其发病年龄关系密切(r=-0.91,P<0. 05) .结论 ADHD患儿存在生物运动感知能力障碍,发病年龄越小,表现越差,且这种感知能力障碍可能与ADHD患儿额叶功能异常有关.

Biological motion perception in children with attention deficit hyperactivity disorder

Objective To explore biological motion perception in children with attention deficit hyperactivity disorder (ADHD) and further to investigate the factors related to the impairments. Methods A duration discrimination task was operated by forty-six children with ADHD and forty-six matched health controls (HCs). Results The point of subjective equality (PSE) was negative value (-0. 30 ±0. 35) for HCs, and there was a significant difference compared with" PSE =0 " by one sample t test ( t =-5. 83,P < 0. 05 ). Compared with HCs,the PSE for ADHD was positive vaule (0. 06 ±0. 63), and significantly increased(t =0. 34 P< 0. 05 ). Pearson correlation analysis showed that there was significant correlation between the biological motion perception and the age of onset (r=-0. 91, P <0. 05). Conclusion The children with ADHD have an impairment of biological motion perception and the younger the age of onset, the worse the performance. The disorder might be attributed to the dysfunction of the frontal lobe.
