1. Introduction

Introduced the origin, development, and application of construction grammar as an important theory of cognitive linguistics in the field of first language acquisition. Discussed the attempts and achievements of construction grammar in second language acquisition research, including the studies of Cadierno U0026 Eskildsen, De Knop U0026 Gilquin, Shi Chunhong, and others. At the same time, it is pointed out that there is controversy in the application of construction grammar theory in second language acquisition, especially regarding the issue of self consistency with generative grammar. The article raises questions and opinions on the application of construction grammar in adult second language acquisition by studying Goldberg's works.

What is the unit of construction grammar?

Explored the concept and development of construction as the fundamental unit of language in construction grammar. Goldberg defines construction as the pairing of form and meaning, proposing that the extension of construction can extend from morphemes to discourse, emphasizing that grammatical knowledge is presented through a construction network. However, Goldberg still relies on traditional terminology in practical use and has not fully implemented the concept of construction. The chapter points out that although structural grammar is reasonable, the hierarchy and combination of grammatical units are still important. It is recommended to use traditional terminology to improve economy and clarity.

Can learners automatically summarize constructions from examples?

Explored the question of whether second language learners can automatically summarize constructions from language examples. Goldberg emphasizes the importance of generalization ability in first language acquisition, but the author questions whether second language learners possess the same ability. Bencini u0026 Goldberg's experiment showed that even with prompts, adult English native speakers still primarily rely on verbs rather than constructions when classifying. Dong Yanping and Liang Junying's experiment found that Chinese English learners at the beginner level rely more on verb cues, while learners at the intermediate and advanced levels tend to use constructions. Cadierno u0026 Robinson and Zhu Minwen's research also shows that Chinese second language learners with different native language backgrounds perform weaker in structural output. Kong Lingyue's research found that even high-level learners find it difficult to achieve automation in extracting the form and meaning of constructions. These research findings indicate that second language learners have limited ability to summarize constructions during the acquisition process, making it difficult for them to automatically form a complete construction awareness.

Is the construction more readily available than the verb?

Explored the role of construction grammar in second language acquisition, particularly the comparison between constructions and verbs in predicting sentence meanings. Goldberg proposed that constructions have cue validity equivalent to verbs, and believed that constructions are the preferred factor for predicting sentence meaning. However, the author questions this and points out that in actual language use, the appearance of feature words may activate semantic cognition more directly than the complete syntactic structure. By analyzing the oral data in the interlanguage corpus, it is found that learners may first determine the use of feature words and then construct the entire structure during the language production process. Therefore, constructions may not necessarily be more readily available in second language comprehension and production than verbs or other feature words. Utilizing feature words to store or trigger semantic information may be a more cost-effective strategy in adult second language acquisition.

Does the frequency and quantity of instances play a decisive role?

Explored the role of instance frequency and quantity in the acquisition of construction grammar. Research has shown that the frequency and variability of instances are important foundations in children's language acquisition, and the frequency of constructions contributes to the clarity of language representation. However, there is no consensus on the reasons for the frequency effect in second language acquisition. Some high-frequency words are difficult to acquire, and high-frequency input does not necessarily lead to a significant improvement in second language proficiency. The high-frequency examples within the structure may promote structure generalization, but the language proficiency of the learner is the decisive factor in the output performance of the structure. Adult second language acquisition may be more inclined to use rule-based approaches rather than implicit learning relying on a large number of instances.

6. Are adults conservative when acquiring a second language?

Explored the issue of conservatism in adult second language acquisition. Goldberg proposed that children exhibit conservatism in the early stages of first language acquisition, but adult conservatism is negatively correlated with age. Adults are able to use new words in argument constructions even if they have not seen this usage before. Empirical research supports that adults are willing to expand their verb usage when learning new constructions. By analyzing the interlanguage corpus, it was found that adult second language learners have rich verb usage in the "ba" and "increasingly X" constructions, and the output content exceeds the input range, indicating that adult second language learners can quickly generalize the use of new constructions from the beginning.

How do you view the impact of a single word?

Explored the application of construction grammar in second language acquisition and its relationship with first language influence. Goldberg proposed that adult second language acquisition is different from child first language acquisition, as adults have mature metacognition and cognitive abilities that may not fully conform to the interpretation of construction grammar. One language has negative effects on second language acquisition, such as conceptual space distortion, heavy cognitive load, and overgeneralization, but it also has positive effects, such as using one language vocabulary and structural categories to promote second language learning. However, Goldberg holds a pessimistic attitude towards the negative effects of the first language and has not provided a solution, indicating the limitations of construction grammar in second language acquisition.

How to view rules?

Explored the application of construction grammar in second language acquisition and its fuzzy handling of rules. Goldberg proposed that constructs can be freely combined, but the combination rules are not clear, which may increase the burden on learners. Children's first language acquisition relies on the accumulation of examples, but it takes a long time, while second language acquisition based solely on usage and induction has a high time cost and may reduce the sense of achievement of adult learners. Supporters believe that second language teaching should not rely solely on rule descriptions, but should be combined with rules. In error correction problems, targeted feedback from direct negative evidence on second language learners' errors is a positive way to promote learning. It should be combined with clear rule explanations to improve acquisition speed and effectiveness, in line with adult cognitive needs.

Why isn't the second language acquisition research labeled as "construction grammar" based on usage?

Doubts have been raised as to whether many current second language acquisition studies that claim to be "construction grammar" are truly based on the theory of construction grammar. It is pointed out that these studies often only borrow the concept of construction grammar, and still use traditional grammar research paradigms in terms of methods, such as acceptability judgment and error analysis. Although there have been studies attempting to verify the role of key factors in construction grammar theory in second language acquisition, these studies often use controlled experimental methods and are not based on natural language use. The author emphasizes that the theory based on usage should examine the structural properties based on the corpus in the natural context, and currently there are few studies that use methods such as regular longitudinal recordings, qualitative interviews, or large-scale interlanguage corpus analysis to explore the process of second language acquisition in depth. Therefore, although many studies are labeled with construction grammar, they do not fully reflect their core spirit based on usage.

10. Conclusion: There should be some trade-offs in the application of construction grammar in second language acquisition

Discussed the application of construction grammar in second language acquisition, emphasized its new perspective for second language acquisition, and proposed four aspects to consider when applying it: accepting Goldberg's construction definition, not fully accepting Pan Constructivism; Adult second language acquisition may be based on rules rather than just usage; Attention should be paid to both positive and negative transfer of words; Accept research methods based on usage, such as follow-up interviews and corpus analysis.
