【摘要】：本研究采用组群研究（group study）的方法，使用延迟选择范式（Choice-DelayTask, C-DT），以ADHD和正常对照组儿童为对象，在加入不同性质额外刺激的条件下，考察了两组儿童延迟厌恶水平的变化。本研究包括两个实验。实验1在延迟选择任务中加入两种不同性质的视觉额外刺激，分别考察两组儿童在基线、单调图片刺激、有意义图片刺激三种条件下的延迟厌恶水平。结果发现，基线条件下，，ADHD组与正常对照组差异显著；单调图片刺激条件下，ADHD组与正常对照组差异显著；有意义图片刺激条件下，ADHD组与正常对照组差异显著；ADHD组在基线条件下与有意义图片刺激条件下的成绩差异显著。实验2在延迟选择任务中加入两种不同性质的听觉额外刺激，分别考察两组儿童在基线、单调声音刺激、有意义声音刺激三种条件下的延迟厌恶水平。结果发现，基线条件下，ADHD组与正常对照组差异显著；单调声音刺激条件下，ADHD组与正常对照组差异显著；有意义声音刺激条件下，ADHD组与正常对照组无显著差异。本研究得到以下结论： 1）ADHD儿童存在延迟厌恶倾向。 2）有意义视觉额外刺激的加入可以降低ADHD儿童延迟厌恶水平；单调视觉刺激的加入对ADHD儿童延迟厌恶水平没有显著的降低作用。 3）有意义听觉额外刺激的加入，可以使ADHD儿童表现趋向正常化，未表现出延迟厌恶倾向；单调听觉额外刺激的加入对降低ADHD儿童延迟厌恶水平没有显著的作用。 4）在单调和有意义条件下，视觉刺激与听觉刺激对ADHD组儿童延迟满足的促进效应量均没有显著差异；正常组儿童在单调条件下，听觉刺激的促进效应量显著小于视觉刺激的促进效应量，而有意义条件下，两种刺激的促进效应量没有显著差异。
[Abstract]:In this study, a cluster study group study was used to investigate the changes of delayed aversion levels in two groups of children under the condition of adding additional stimuli of different properties, using the delayed selection paradigm Choice-DelayTask.C-DTT, and taking ADHD and normal children as subjects.This study includes two experiments.In experiment 1, two kinds of visual extra stimuli of different properties were added to the delayed selection task, and the delay-aversion levels of the two groups were investigated under three conditions: baseline, monotone picture stimulation and meaningful picture stimulation.The results showed that there were significant differences between ADHD group and normal control group under baseline condition, and significant difference between ADHD group and normal control group under monotone picture stimulation.There were significant differences between ADHD group and normal control group under the condition of meaningful picture stimulation, and the scores of ADHD group under baseline condition and meaningful picture stimulation condition were significantly different.In experiment 2, two kinds of auditory extra stimuli of different properties were added to the delayed selection task. The delay-aversion levels of the two groups were investigated under three conditions: baseline, monotone sound stimulation and meaningful sound stimulation.The results showed that there was significant difference between ADHD group and normal control group under baseline condition, significant difference between ADHD group and normal control group under monotonic sound stimulation, and no significant difference between ADHD group and normal control group under meaningful sound stimulation.The conclusions of this study are as follows:Children with 1)ADHD have a tendency to delay aversion.2) the addition of significant visual extra stimulation can reduce the delayed aversion level of ADHD children, but the addition of monotone visual stimulation has no significant effect on the delayed aversion level of ADHD children.3) the addition of meaningful auditory extra stimulation could normalize the performance of children with ADHD without showing a tendency of delayed aversion, but the addition of monotone auditory extra stimulation had no significant effect on reducing the level of delayed aversion in children with ADHD.4) under monotonic and meaningful conditions, there was no significant difference between visual and auditory stimuli in promoting the delayed gratification of children in ADHD group, while in normal group, there was no significant difference between the two groups.The stimulative effects of auditory stimuli were significantly smaller than those of visual stimuli, but there was no significant difference between the two stimuli under meaningful conditions.
