Co-activation Experiment Of Cross-language Cross-word Classes In Thai-Chinese Bilinguals In Sentence Context

In the process of bilingual language understanding,the state of non-target language is one of the hot topics in the bilingual research.With regard to this problem,there are mainly two opposing theories: selective processing theory and non-selective processing theory.The existing researches mainly use the isolated vocabulary as the material to examine the non-target language state when the bilingualists use the target language,that is,whether there is a phenomenon of cross-language activation.According to the bilingual language representation theory,cross-language activation may occur at the conceptual level or lexical level.With the deepening study of cross-language activation,the researchers began to integrate the sentence context into the study of cross-language activation,and first focused on whether there is the cross-language activation phenomenon in the sentence context.In cross-language activation research based on isolated vocabulary,it is commonly found that there is cross-language speech activation in the weak language,while it does not necessarily appear in the language understanding task in sentence context.So,will the sentence context has a certain impact on the cross-language activation? And what is the impact of the sentence context on the cross-language activation? This is a question that needs to be explored.At the same time,it should be noted that the study about the cross-language activation in the sentence context is rare,and the key reason lies in the research paradigm.How to design a reasonable paradigm to examine the phenomenon of cross-language activation in the context,is the direction that needs researchers to explore.For example,Vandeberg et al.(2011)research paradigm is not sufficient to support its findings.In this study,we adopted and revised the research paradigm of Vandeberg et al.(2011),adopted the dual task paradigm,asked the subjects to listen to Chinese sentences at the same time to see the picture,and select the skilled and unskilled Thai-Chinese bilinguals,to examine whether the Chinese and Thai language that do not belong to the same text system produce speech-based cross-language activation in the sentence context.The experimental results show that there is a coactivity between the Thai and Chinese bilinguals in the context of sentences,and the coactivity of the unskilled ThaiChinese bilinguals is more pronounced than the skilled bilinguals.The results support the nonselective processing theory.This paper explains the experimental results from two aspects of theory and practice.
