【摘要】：目的：探討注意缺陷多動(dòng)障礙(ADHD)兒童及對照組兒童在捆綁和非捆綁特征干擾下視覺客體工作記憶的特點(diǎn)及其差異。方法:本研究實(shí)驗(yàn)主要采用單探測的變化檢測范式，，根據(jù)美國精神疾病診斷和統(tǒng)計(jì)手冊第4版(DSM-IV)，對符合ADHD診斷標(biāo)準(zhǔn)的30名門診患兒及年齡、性別相匹配的33名正常兒童，進(jìn)行兩組2（組別：ADHD組、正常組）×2（干擾類型：顏色干擾、形狀干擾）的混合實(shí)驗(yàn)設(shè)計(jì)，因變量是干擾效應(yīng)量。結(jié)果：在捆綁特征干擾任務(wù)中，組別主效應(yīng)及組別與干擾類型的交互作用顯著，ADHD兒童對形狀特征的視覺客體工作記憶效應(yīng)量顯著高于正常組兒童；在非捆綁特征干擾任務(wù)中，組別主效應(yīng)差異顯著，組別與干擾類型的交互作用不顯著。結(jié)論：（1）總體而言，ADHD兒童在視覺客體工作記憶方面存在缺陷；（2）捆綁特征會(huì)對ADHD兒童的視覺客體工作記憶造成影響，但這取決于干擾特征的類型；（3）非捆綁特征也會(huì)對ADHD兒童的視覺客體工作記憶造成影響，但不存在具體的干擾特征維度對其的影響，非捆綁特征干擾對ADHD兒童的影響存在一致性。
[Abstract]:Aim: to investigate the characteristics and differences of visual object working memory in children with attention deficit hyperactivity disorder (ADHD) and control children under the interference of bundled and unbundled features. Methods: according to the American Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), 30 out-patient children and their ages who met the diagnostic criteria of ADHD were investigated by using the single-detection paradigm of change detection in this study, according to the American Diagnostic and Statistical Manual for Mental Disorders (4th Edition). Three hundred and thirty-three normal children were randomly divided into two groups: group 2 (group ADHD, group normal) 脳 2 (interference type: color interference, shape interference). The dependent variable was the amount of interference effect. Results: in bundled feature interference task, the main effect of group and interaction between group and type of interference were significant. The working memory effect of visual object of ADHD children was significantly higher than that of normal group. In non-bundled feature interference task, the main effect of group was significantly different, and the interaction between group and interference type was not significant. Conclusion: (1) in general, ADHD children have defects in working memory of visual objects, (2) bundling features can affect the working memory of visual objects in ADHD children, but this depends on the type of interference features. (3) non-bundling features also affect the working memory of visual objects in ADHD children, but there is no specific interference feature dimension affecting them, and the influence of non-bundling features interference on ADHD children is consistent.
