【摘要】：目的:觀察學習漢語語音20 h的墨西哥漢語習得者普通話上聲識別的腦偏側化情況,討論聲調(diào)的言語信息量與腦偏側化的關系。方法:用非隨機任意抽樣法抽取15名(男8名,女7名)以西班牙語為母語的墨西哥漢語習得者作為研究對象,年齡20~32(中位年齡24)歲。習得者學習漢語語音20 h后,用普通話的上聲元音音節(jié)作為實驗材料,用雙耳分聽技術對其進行普通話上聲識別測試,分別計算正確反應時間和錯誤率。結果:學習漢語普通話語音20 h的墨西哥漢語習得者上聲雙耳識別的反應時間和錯誤率經(jīng)Wilcoxon檢測顯示:左右耳(大腦左右半球)反應時間的差別無統(tǒng)計學意義(Z=-0.341,P=0.733);左耳(大腦右半球)的錯誤率顯著低于右耳(大腦左半球)(Z=-2.091,P=0.036)。結論:墨西哥漢語習得者的聲調(diào)感知的腦偏側化與聲調(diào)所表示的言語信息量有關,墨西哥漢語習得者的聲調(diào)音義范疇的建立是逐步建立起來的。
[Abstract]:Objective: to observe the brain lateralization of Mandarin recognition in Mexican Chinese learners who have been learning Chinese pronunciation for 20 hours, and to discuss the relationship between tone speech information and brain lateralization. Methods: fifteen Mexican Chinese learners (8 males and 7 females) with Spanish as their mother tongue were selected by non-random sampling. The age was 20 鈮，
