基于时间序列模型分析的ADHD儿童听觉持续性注意研究

The research of audio sustained attention in ADHD based on time series model

通过建立时间序列模型,对ADHD儿童与正常儿童的听觉持续性注意水平进行拟合,并分析2组被试间的差异,动态地观测ADHD儿童的注意缺陷水平,并实现对ADHD儿童注意水平的预测.被试选取ADHD儿童30名,正常儿童10名,对被试进行听觉持续性操作测试,对每个序列的平均正确率进行时间序列模型分析,比较2组被试间的差异.根据数据的特征选用Holt模型对ADHD儿童的持续性注意水平进行建模及拟合,而正常儿童组则选用简单模型(Simple).与正常儿童相比,ADHD儿童存在显著的注意缺陷特征,持续性注意水平随时间变化表现出明显的下降趋势.

The purpose of this research is to fit the curve of hearing sustainable level by establishing time series model,analyzing the differences between the two test groups-normal children and ADHD children.Observe the attention defects level of ADHD children dynamically,and to predict ADHD children＇s attention level.Method： To sample 30 ADHD children,10 normal children,test their hearing sustainable level.Analyze average accuracy of each series by time series model,and compare the differences between two tester groups.Result： Holt model was chosen to construct model and fit the ADHD children＇s attention level according to the characteristics of the data and choose simple model to test normal children.Compared with normal children,ADHD children have significant characteristics of attention deficit and their persistent attention level indicates obvious decline tendency as time changes.
