集中注意法对健康人押韵真词的分听研究

The Dichotic Listening Research for Rhyming True Words by Focused Attention on Healthy Subjects

目的 :探讨健康人对汉语中押韵真词及其中韵字与非韵字的认知与加工 .方法 :在集中注意状态下 ,用自行设计的押韵真词 ,对 6 3名健康被试 (组 1=2 0 ,组 2 =43)进行耳优势的检查 .结果 :组 1:①真词的均数 ,左右耳未见显著差异 (P >0 0 5 ) ;②左耳中真词的非韵字均数显著大于韵字均数 ,但右耳却相反 .组 2 :①真词均数为右耳大于左耳 (P <0 0 5 ) ;②押韵真词中非韵字均数大于韵字均数 (P <0 0 5 ) .结论 :汉语真词的加工与认知以左侧半球占优势 ,右侧半球起协同作用 ,和西方语音文字相比 ,其参与程度更高或协同性更好 。

Objective: To study the mechanism by which rhyming true words are processed. Methods: The study examined the ear advantage of 63 healthy subjects (group 1, n =20, n =43) using self-designed a kind of rhyming true words by the method of focused attention. Results: group 1 (1) The means of the true words have no significant difference in both ears (P>0.05). (2) For true words in left ears, the means of non-rhyming Chinese characters are higher than those of rhyming Chinese characters. But it is opposite in fight ears. Group 2: (1) The means of true words in right ears are highter than those in left ears (P<0.05). (2) For rhyming words, the means of non-rhyming Chinese characters are higher than those of rhyming Chinese characters (P<0.05). Conclusion: For process and cognition of true words on healthy subjects, the left hemisphere has main dominance. The right hemisphere is inferior to the left. Compared with westen Latine language, however, the participant role of the right hemisphere is much more. Moreover, the younger the subject is, the more paticipating the right hemisphere is or the two hemispheres cooperated better.
