The Characteristics Of Implicit Working Memory In Children With Different Kinds Of Learning Disabilities: Evidence From ERP

Today, the children with different kinds of learning disabilities are becoming more and more widespread concern. Among them, the development of dyslexia in th e all type of development of learning disabilities children accounted for the majority proportion. It is one of the main types of the development of learning disabilities; an d the development of dyscalculia children is about 3%-6.5%. With the deep researchon the children learning disabilities, people found that working memory defect may lead all kinds of learning disabilities. The study found that the development of childr en with learning disabilities in short-term memory span and working memory have di fferent degrees of defects, there were deficiencies in children with the development o f dyslexia in all system of working memory. There were dificiencies in children withthe development of dyscalculia have defects in central executive system and visual s pace system defects in working memory.Hassin et al(2009) on the basis of the previous studies of implicit memory i n work formally proposed the existence of this proposition, the experimental paradigm u sing modified visual-pattern reversal, using the experimental design clever proved implic it working memory does exist. This research through the experimental paradigm of vis ual- pattern reversal, with high time resolution of ERP technology from the electrophysi ological proves that the students with mathematical learning difficulties the existence of i mplicit working memory and implicit working memory defect, and investigate the elec trophysiological mechanism, memory research on implicit learning difficult work will b e conducive to learning difficulties of potential development of learners, and provides a n ew perspective for evaluation and education intervention learning difficulties.Experiments using ERP technology from the electrophysiology in visual leve l mathematical proof that children with learning difficulties also exist implicit working m emory, experiment two based on one experiment, to explore the mathematics learning dif ficulties in children and normal children the existence of implicit working memory diffe rences from the electrophysiology. The results showed that:(1) the difference between t he experimental one from pattern and broken pattern conditions that, children with mat hematical learning disabilities exist implicit working memory.(2)The studied in two chil dren with learning difficulties and normal children in implicit working memory, that lear ning disabled children and normal children, hidden working memory waveform is basic ally the same. The children with learning difficulty P300 is relatively small, reflecting t he children with learning difficulties or the lack of attention resource is not adequate t o allocation of attentional resources, that children with learning difficulties have attentio n defect.
