抑制和易化条件下的双语优势效应(硕士)(论文28000字)
中文摘要
随着经济全球化的发展，各国之间的联系正在加强，掌握两国语言的双语者正逐步增多。随着对双语经验的重视，在心理学领域，研究者们开始关注学习二语对于学生在其他方面的优势，已有研究考察双语者的认知优势，比如双语者比单语者在涉及到任务转换、抑制干扰等能力上显著优秀，证实了双语优势效应的存在，但是关于双语优势效应的内在机制还没有一个定论。Green（1998）的双语语言产生抑制控制模型认为，双语者更好的抑制控制能力是双语优势效应的内在机制。然而，有少数研究发现，双语者较好的认知控制能力不仅在冲突任务中的抑制条件下存在，在一致条件下也发现了双语者更快的反应时和较低的错误率。对于这一发现，研究者们并没有得出统一的结果，其稳定性还需进一步的实验实证。因此，本研究在国内外研究的基础上，进一步考察不同熟练程度的双语者在抑制条件和易化条件下的双语优势效应现象。
本研究采用了三个实验来探讨这一问题。实验一采用Stroop范式考察了不同熟练程度双语者在冲突任务中抑制和易化条件下的双语优势效应，结果发现：熟练双语者不仅在抑制条件下的反应时显著短于非熟练双运者，在一致条件下的平均反应时也显著短于非熟练双语者；实验二采用Simon范式考察了不同熟练程度双语者在反应抑制条件和一致条件下的双语优势效应，结果发现在反应抑制条件下，熟练双语者的反应时短于非熟练双语者，在一致条件下熟练双语者的平均反应时也短于非熟练双语者；为更好的排除被试可能由于冲突任务中具有的较高的注意监控能力，实验三采用RSVP范式考察了完全易化条件下不同熟练程度双语者的双语优势效应，结果发现：熟练双语者在T2上反应时显著短于非熟练双语者，且错误率更低。

基于三个实验的结果，得到以下结论：
（1）熟练双语者相比于非熟练双语者在干扰抑制条件下具有更好的抑制控制能力，出现了双语优势效应。
（2）熟练双语者相比于非熟练双语者在反应抑制条件下具有更好的反应抑制能力，出现了双语优势效应。
（3）双语优势效应在易化条件下也可能存在

Abstract
With the development of economic globalization, the ties between various countries are being strengthened, and the number of bilinguals in both languages is gradually increasing. With the emphasis on bilingual experience, in the field of psychology, researchers have begun to pay attention to the advantages of learning L2 in other aspects. Studies have examined the cognitive advantages of bilinguals such as task switching, interference suppression and other abilities, confirming the existence of bilingual cognitive advantage effect, but there is unknow about the intrinsic mechanism of the bilingual advantage effect. On the basis of bilingual language production, Green(1998) proposed that the bilinguals’ ability to better control is the intrinsic mechanism of bilingual advantage effect. However, a few studies have found that bilinguals' better ability of cognitive control not only exists in the conflict condition, but also in consistent conditions. For this discovery, the researchers did not come to a unified result and a definite conclusion. Therefore, based on the researches, this study further examines the bilingual advantage effect in the conditions of inhibition and facilitation in bilinguals with different proficiency levels.

Three experiments were used to explore this issue. Experiment 1 used the Stroop paradigm to examine the bilingual advantage effect of bilinguals with different proficiency levels under the inhibition and facilitation conditions in the conflict task. The results show that not only the proficient bilinguals are significantly shorter than the non-proficient bilinguals, but also the mean reaction time in all conditions was also significantly shorter. Experiment two used Simon paradigm to examine the bilingual advantage effect of bilinguals with different degrees of proficiency. Experiment results showed that in the condition of reaction inhibition, proficient bilinguals responded shorter than non-proficient bilinguals, and were shorter in consistent conditions; for better exclusion higher attention in conflict tasks, In the third experiment, using the RSVP paradigm, we examined the bilingual advantage effect of bilinguals. The results showed that proficient bilinguals were significantly shorter than non-proficient   [资料来源：http://www.doc163.com]
bilinguals at T2 and had lower error rates.
Based on the results of the three experiments, the following conclusions are obtained:
(1) Proficient bilinguals have bilingual advantage compared with non-proficient bilinguals under interference inhibition.
(2) Compared with non-proficient bilinguals, proficient bilinguals have better response inhibition ability under the condition of reaction inhibition.
(3) Bilingual advantage effect may also exist in the condition of facilitation.
