Abstract
目的:探討漢語聽寫障礙兒童形音聯結缺陷的原因.方法:從小學三四五年級共412名兒童中,篩選出聽寫障礙組兒童21名,同時選擇年齡智力水平閱讀水平相當的對照組兒童21名.採用變化檢測範式,以符號日文韓文為視覺刺激材料;以單音節聲音為聽覺刺激材料,通過考察兩組兒童在探測刺激正確捆綁交換捆綁形變捆綁音變捆綁四種條件下的判斷正確率,探索聽寫障礙兒童的語音-音聯結缺陷源於跨形音聯結任務中的多源和跨加工缺陷加工缺陷加工缺陷跨加工缺陷跨加工缺陷跨加工缺陷跨加工缺陷或跨加工缺陷的通道缺陷.結果:1在探測刺激正確捆綁和形變捆綁條件下,兩組被試正確率差異沒有統計學意義;2在探測刺激交換捆綁條件下,聽寫障礙組正確率顯著低於對照組;3在探測刺激音變捆綁條件下,聽寫障礙組正確率低於對照組,達到邊緣顯著.結論:形音連結缺陷可能源自於視聽跨通道的連結缺陷和語音加工缺陷.
Objective: Based on previous studies, children with Chinese dictation difficulties have verbal-visual crossmodal association deficits. The aim of this research was to explore the cause of verbal-visual cross-modal deficits in them.Methods: Totally 412 children recruited from a primary school took part in the screening tests for participants. Forty-two children took part in the experiment, including 21 with spelling difficulties, and 21 age-, intelligence level-, and reading level-matched normal controls. Change detection paradigm was used. Symbols, Japanese hiragana, katakana, Korean alphabets were used as visual stimulus. Single syllable sound stimulus was used as verbal stimulus. In order to explore the cause of the visual-verbal association deficits, we compared two groups' accuracy rates of four probe stimulus types: right bound condition, exchanged bound condition, visual stimulus changed condition, and verbal stimulus changed condition. Results:1In the right bound condition and visual stimulus changed condition, the two groups showed no significant differences. 2In the exchanged bound and verbal stimulus changed condition condition, the performances in the diction difficulties group were both poorer than the control group. Conclusion: Verbal-visual connection deficit in children with Chinese dictation difficulties may caused by the visual-verbal cross-modal association deficits and underlying phonological deficits.
