The Effects Of Bundled And Unbundled Features Interference On The Visual Object Working Memory Of Children With ADHD

The research is aimed at discussing the characteristics and differences of the visualobject working memory of children with ADHD and the control group in the interferencecondition of bundled and unbundled features. The experiments mainly use the singledetecting change detection paradigm.The participants are30children who meet thediagnostic criteria of DSM-IV and33normal children,their ages and genders aresuited.Both of the two experiments are2×2mixtured experimental designs.Theindependent variables are group and type of interference.The group contains ADHD groupand normal group and the type of interference contains colour interference and shapeinterference.The dependent variable is the effect size of the interference.The results showthat in the task with bundled features interference,the main effect of group isoutstanding,so is the interaction between group and type of interference.The ADHDchildren’s effect size of the visual object working memory of the colour is significantlyhigher than that of normal children.While in the task with unbundled featuresinterference,the difference of the effect size of group is outstanding,but the interactionbetween group and type of interference is not outstanding. So the research draws thefollowing three conclusions: Firstly,in general,in the aspect of visual object workingmemory,ADHD children exist detects.Secondly,bundled features have impacts on ADHDchildren’s visual object working memory and the impacts depend on the types ofinterference features.Thirdly,compared with bundled features,unbundled features also haveimpacts on ADHD children’s visual object working memory,while the types of interferencefeatures have no impacts on them.And there exists consistence in the influence ofunbundled features interference on children with ADHD.
