The main purpose of the traditional second -language acquisition research is to clarify the learner's acquisition process and its influencing factors，The main research target is the intermediary corpus of the learner (natural output corpus or controlling output corpus)，is Product (Product)，instead of Processing (processing)，If you rely on intermediary language corpus, errors、Sequence of acquisition、Studies in the development process。You can see，The traditional research paradigm emphasizes the static offline research (off-line)，instead of processing process of intermediary language，Even if you understand it in an intermediary、Online (on-line) research。Such non -actual research paradigm failed to further explore the language acquisition mechanism of two -language learners。

In recent years，Research methods based on neurop awareness science have been widely used in the study of two -character acquisition。Scholars from the perspective of neurological linguistics，Adopting brain electrical and brain imaging technology to study the problem of two -language acquisition，Explore the second language learner online、The neural cognitive mechanism of real -time processing two -character machining。Under the background of the rapid development of cognitive science，Two -language Xibi research bet365 live casino games should keep up with the forefront of international research，Drawing and using the paradigm of cognitive neuroscience，Theoretical of enhancing discipline construction、Science and Times。

Event-related potential technology (Event-Related Potentials，ERP) as an example，The research of the use of this technology on the process of two -character processing shows a strong trend。ERP is one of the methods of cognitive neuroscience，Reflects the real -time electro -science indicators of the hidden brain neurons in the cognitive processing process，The characteristics of time resolution with millisecond -level and online real -time measurement。

grammar is one of the key contents of two -character learning。Chinese does not have morphological changes in a strict sense，Mainly use the sequence and virtual words to represent grammatical relationships and grammar meaning。Different languages ​​with the abundant shape，When you learn Chinese sentences，Except the rule of law，The acquisition of semantic and consolidated systems is also very important。Current，Internationally, some scholars have begun to use ERP to examine the cognitive neural mechanism of processing syntax。Among them, some studies are found，When expressing similar information in a sentence，Language devices with different grammarization，It may present different processing mechanisms。If in Indo -European language with tense，When processing time information, a formal sentence mechanism is used，In a language without bet365 live casino games tense，Time adverbs with rich processing semantics use vocabulary semantic mechanisms，Machining high grammatical body standards use a morphological sentence mechanism，Although the time information expressed in two types of sentences is similar。The concept and paradigm of the above research provides a reference for the study of Chinese two -language acquisition mechanism。

The acquisition is one of the issues of the second language processing research，Can those who can get the purpose of the purpose，Can it reach the level of language processing similar to mother tongue，All need to be answered。Only by observing the offline results of learners，May not be able to answer the above questions。For example，If you get a high score in some tests，This test result does not mean that the two -language person has a processing mechanism of a mother tongue，Because it is difficult for us to judge that they depend on language ability or explicit language knowledge，It is impossible to know the automation level of their language processing。Existing theory thinks，Factors affecting the processing of the second sentence are age、two -character level、Similarity of the first language and two languages、Learning environment、Difficulties in the structure of the sentence。Overseas Chinese learners' own particularity，To a certain extent, the advantage of acquiring Chinese，This may have a positive impact on its processing mechanism，So as to promote the fast gain of the level of language processing level。ERP is bet365 live casino games to explore the problem of acquisition of overseas Chinese learners、The cognitive mechanism of understanding its Chinese sentence processing provides breakthroughs。

In ERP research for sentence processing，违 违 违 违，Specific sentences that violate the sentences will form a greater stimulus on the subject compared to the correct conditions，Some specific stimuli will trigger a typical predictable ERP mode。Mother tongue ERP study related to sentence processing，Mainly N400、P600、An and other ERP ingredients。

N400 is a negative wave caused by the time window of about 400 milliseconds，Mainly related to semantic violations，Semantic contact、Disposity such as words and other words may produce N400。P600 is a positive wave of 500-900 milliseconds after stimulation，Usually reflect the form of violations、Sentence method Machining complexity, etc.。an (front forehead wave) will appear at different time windows。Scholars think，The front forehead wave of different time windows is caused by different stimuli，Early left front forehead negative wave (ELAN) that appeared at 100-300 milliseconds was caused by word violations，and appear on the left front forehead of 300-500 milliseconds (LAN), which is caused by morphological sentence processing。other，In grammar violation，It will cause ERP dual -phase mode (biphasic ERP Pattern)，It causes Lan to accompany P600。

n400 is usually used as an ERP index at the word semantic semantic level，P600、An is usually used as an ERP indicator bet365 live casino games at the clause level。But the literature display，Different types of sentences violate the early negative components induced in the same period，This is related to the degree of role of vocabulary semantic information in processing。If you rely more on vocabulary semantics，It is more like N400 in the incubation period and scalp distribution。Features combined with Chinese，Virtual Words are one of the important grammatical methods of Chinese，But some words are unknown，Although it is determined as a virtual word，But there are still some vocabulary semantics in the transitional state of grammar，It may also lead to N400。In the study of two -character processing，Usually based on the results of mother tongue processing as a reference to discuss the two -character processing。To understand the Chinese sentence processing mechanism of overseas Chinese learners，It needs to be processed by Chinese mother tongue as a reference，This is also the direction that needs further development in Chinese learning research。

In addition to the first language processing，Existing two -character processing research also brings us enlightenment。Related research indicates，In semantic violations，Two language also appears N400 caused by mother tongue processing，In the violation of the law of the law, P600 ingredients similar to their mother tongue processing are often caused，But the ERP incubation period delay observed during the processing of the second language，Small volatility。In some bet365 Play online games two -sentence sentence ERP studies，Stimulation of the same type，It will trigger different ERP components of different two -character levels，If a low -level learner trigger N400，and high -level learners have caused P600 ingredients that are similar to the mother tongue.。This shows that with the increase in the level of the second language，ERP effect may produce qualitative changes，P600 is even used as a logo similar to mother tongue processing in some studies。Two states may adopt different syntax processing strategies at different levels: from vocabulary semantics to syntax processing，When the processing information of more complicated processing，Low -level two -language person depends more on vocabulary semantics，High -level two -character, rely on the clause structure。

Features of Chinese grammar and semantics，We might as well make bold assumptions，Chinese as a second language and Indo -European language two language learning may be different。Of course，These assumptions need to be confirmed or falsified by cognitive neuroscience and technology。At present, domestic two -character acquisition research already has the conditions to establish a mature discipline theoretical system，Two -language learning research has also entered a new stage of development。In view of the characteristics of its interdisciplinary，Should follow the pace of the times，Absorption of cognitive neuroscience，Based on the empirical research paradigm further regulates the theoretical of the second language Bet365 lotto review acquisition discipline、Scientific construction。
