【摘要】：目的:研究部件字形加工难度对听写困难儿童字形-空间捆绑编码的影响。方法:采用变化检测范式,从苏州某小学四至六年级的儿童中筛选年龄和智商匹配的听写困难儿童、对照组儿童各25名,实验材料以部件字形的相似程度作为部件加工难度的指标,对比听写困难组儿童和对照组儿童在字形-空间记忆任务上的成绩差异。结果:两组被试在成绩上组别主效应不显著,但在反应时数据上,组别和材料的交互作用显著,听写困难儿童在部件字形高相似条件下的反应时明显高于字形低相似条件,而对照组被试在两个实验条件下的反应时没有明显差异。结论:在字形-空间的捆绑编码时,听写困难儿童存在明显的字形难度效应,在字形加工难度较低时,听写困难儿童的捆绑加工水平较为正常,但是,一旦提高字形加工难度,听写困难儿童就表现出字形-空间捆绑缺陷。
[Abstract]:Objective: to study the effect of the processing difficulty of part glyph on glyph space binding coding in children with dictation difficulties. Methods: change detection paradigm was used. Children with age and intelligence quotient matching were selected from children in grade 4 to 6 in a primary school in Suzhou, and 25 children in control group. The similarity of the shape of parts was used as the index of difficulty in processing parts. Results: the main effect of the two groups was not significant, but in response time data. The interaction between groups and materials was significant, and the response time of children with dictation difficulties under the condition of high similarity of components was significantly higher than that of low similarity of glyph. However, there was no significant difference in the reaction time between the control group and the control group under the two experimental conditions. Conclusion: in the binding coding of glyph space, there is a significant glyph difficulty effect in the children with dictation difficulties, and when the processing difficulty is low. The children with dictation difficulties have a normal level of binding processing, but once the processing difficulty is increased, the children with dictation difficulties have the defect of glyph and spatial binding.

【正文快照】： 听写困难(spelling difficulties)是指在没有阅读障碍病史的情况下,由于某种原因导致儿童的特定拼写技能显著受损(包括口头与笔头正确拼写单词的能力受损),主要表现为拼写成绩落后于同龄(或同智力水平)儿童的现象。听写困难不是由于教育不当、视觉缺陷或精神等问题所致,目前,
