1、26JournalofAudiologyandSpeechPathology2014.Vol22.No.1·临床研究·墨西哥汉语习得者普通话声调识别的脑偏侧化倡1王红斌【摘要】目的观察以西班牙语为母语的墨西哥汉语习得者在识别普通话四声时的脑偏侧化情况。方法以非随机任意抽样法抽取24名(男10名,女14名)以西班牙为母语的墨西哥汉语习得者作为研究对象,年龄20~27岁,平均21.29±2.3岁,在其学习汉语60~70小时后,用双耳分听技术对其进行普通话四声测试,分别统计普通话四声识别的正确反应时间及错误率。结果在受试者识别普通话四声的正确反应时间上
2、,“阴平”的识别显示出右耳(大脑左半球)是优势耳(脑)。在双手主效应上,“阴平”显示出左手优势;受试者在识别“阳平”时,在左手作为反应手时,右耳(大脑左半球)是优势耳(脑),在右手作为反应手时,左耳(大脑右半球)是优势耳(脑);受试者在识别“上声”时,在错误率方面,当受试者左手或右手作为反应手时,都显示出右耳(大脑左半球)是优势耳(脑);去声的识别则未显示出脑偏侧化。结论墨西哥汉语习得者识别普通话四声时出现了脑偏侧化,识别阴平、上声的优势大脑半球是大脑的左半球;对阳平处理的优势脑随反应用手不同而不同;识别去声时,则没有显示出明显的脑偏侧化。【关键
