【摘要】：反应时是一种可靠的心理活动指标,能反映人体神经与肌肉系统的协调性和快速反应能力。为探讨智障青少年这一特殊群体的反应时与运动时特征及其影响因素,本研究对190名10~21岁智障青少年进行了反应时与运动时的测定与分析。结果显示:智障青少年的反应时与运动时在青少年早期表现出随年龄增长而减少的趋势,具有明显年龄特征。智障青少年的反应时与运动时绝对值无明显性别差异,但其随年龄增长而发展的趋势存在较为显著的性别差异。智障青少年的反应时及运动时与其智商无显著相关关系。唐氏智障青少年的反应时特征与普通智障青少年存在差异,但罹患自闭症对智障青少年的反应时未产生影响。系统的运动训练使智障青少年的反应时与运动时缩短。
[Abstract]:Response time is a reliable index of psychological activity, which can reflect the coordination and rapid response ability of human nerve and muscle system. In order to study the characteristics and influencing factors of reaction time and exercise time in a special group of adolescents with mental retardation, this study measured and analyzed the response time and exercise time of 190 adolescents with mental retardation aged 10 to 21 years. The results showed that the reaction time and exercise time of mentally retarded adolescents decreased with the increase of age at the early stage of adolescence and had obvious age characteristics. There was no significant difference in the absolute value of reaction time between mentally retarded adolescents and those in exercise, but there was a significant gender difference in the trend of their development with the increase of age. There was no significant correlation between reaction time and exercise time and intelligence quotient of mentally retarded adolescents. The reaction time characteristics of Down's mentally retarded adolescents are different from those of normal mental retarded adolescents, but autism has no effect on the reaction time of mentally retarded adolescents. Systematic exercise training shortens the reaction time and exercise time of mentally retarded adolescents.
