【摘要】:本研究采用組群研究(group study)的方法,使用延遲選擇范式(Choice-DelayTask, C-DT),以ADHD和正常對照組兒童為對象,在加入不同性質(zhì)額外刺激的條件下,考察了兩組兒童延遲厭惡水平的變化。 本研究包括兩個實(shí)驗(yàn)。實(shí)驗(yàn)1在延遲選擇任務(wù)中加入兩種不同性質(zhì)的視覺額外刺激,分別考察兩組兒童在基線、單調(diào)圖片刺激、有意義圖片刺激三種條件下的延遲厭惡水平。結(jié)果發(fā)現(xiàn),基線條件下,,ADHD組與正常對照組差異顯著;單調(diào)圖片刺激條件下,ADHD組與正常對照組差異顯著;有意義圖片刺激條件下,ADHD組與正常對照組差異顯著;ADHD組在基線條件下與有意義圖片刺激條件下的成績差異顯著。實(shí)驗(yàn)2在延遲選擇任務(wù)中加入兩種不同性質(zhì)的聽覺額外刺激,分別考察兩組兒童在基線、單調(diào)聲音刺激、有意義聲音刺激三種條件下的延遲厭惡水平。結(jié)果發(fā)現(xiàn),基線條件下,ADHD組與正常對照組差異顯著;單調(diào)聲音刺激條件下,ADHD組與正常對照組差異顯著;有意義聲音刺激條件下,ADHD組與正常對照組無顯著差異。本研究得到以下結(jié)論: 1)ADHD兒童存在延遲厭惡傾向。 2)有意義視覺額外刺激的加入可以降低ADHD兒童延遲厭惡水平;單調(diào)視覺刺激的加入對ADHD兒童延遲厭惡水平?jīng)]有顯著的降低作用。 3)有意義聽覺額外刺激的加入,可以使ADHD兒童表現(xiàn)趨向正;,未表現(xiàn)出延遲厭惡傾向;單調(diào)聽覺額外刺激的加入對降低ADHD兒童延遲厭惡水平?jīng)]有顯著的作用。 4)在單調(diào)和有意義條件下,視覺刺激與聽覺刺激對ADHD組兒童延遲滿足的促進(jìn)效應(yīng)量均沒有顯著差異;正常組兒童在單調(diào)條件下,聽覺刺激的促進(jìn)效應(yīng)量顯著小于視覺刺激的促進(jìn)效應(yīng)量,而有意義條件下,兩種刺激的促進(jìn)效應(yīng)量沒有顯著差異。
[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.
