Task complexity and genre effects
While genre-related second language (L2) research has primarily focused on written production and isolated linguistic dimensions, limited attention has been paid to how genre modulates task complexity and linguistic performance in L2 oral contexts. Grounded in two theoretical frameworks—the limited attentional capacity model and the cognition hypothesis—this study investigates how expository and narrative genres influence the complexity, accuracy…
Verb-centric or balanced?
Similar Semantic Category Distributions but Distinct Noun Choices in Nonacademic Second Language Writing of Graduate Students With Different Disciplinary Backgrounds
The disciplinary background of second language (L2) writers can shape their writing style, including their lexical choices. This study examines lexical differences in nonacademic argumentative essays on the same topic by L2‐English graduate students with humanities‐related or science‐related majors. Using natural language processing (NLP) techniques, the study extracts nouns from these writers’ essays and classifies them into 21 semantic categori…
Processing of passives using morphological information within the verb in a second language
This study aims to illuminate the underlying mechanisms of sentence processing in L2 speakers. The phenomenon of interest in the study is the passive structure, which prior research has shown can be challenging for both L1 speakers and L2 speakers to process compared to active structures. Using a visual-world eye-tracking paradigm, this study investigates whether L1-English speakers and L1-Cantonese L2-English speakers employ a morphological cue …
Can large language models be viewed as a cognitive model of human language? Not yet, regardless of reasoning capability and size
Can large language models (LLMs) be viewed as a cognitive model of human language? Do they possess human-like language competence? To address these questions, this study takes a multifaceted approach, comparing the performance of 10 recent LLMs (n = 4000 responses) and 94 humans (n = 3760 responses) on grammaticality judgments and sentence interpretations, focusing on five linguistic phenomena that involve missing material. The analyses show that…
Genre-specific features of second language speech
Each genre is characterized by its distinct linguistic features, which are designed to achieve the particular purpose of its discourse. Despite the wealth of research documenting genre effects, showing higher levels of linguistic complexity in non-narrative genres compared to narrative genres, most studies have focused on written language and linguistic features at the lexical and syntactic levels. To address these gaps, the current study investi…
Individual Differences in Second Language Speakers’ Retrieval and Prediction Processes
Aims and Objectives: Adopting an individual differences approach to second language (L2) processing, the present study examines the roles of internal (L2 proficiency, age of L2 onset) and external (length of L2 immersion) factors in two types of L2 processing—specifically, retrieval and prediction. Methodology: This study focuses on honorifics in Korean, where the use of the honorific verbal suffix is conditioned upon whether the subject refers t…
Effects of goals and strategies on predictive processing
There is ongoing debate about whether prediction is driven solely by bottom-up associative links or is modulated by top-down goals and strategies. The current study attempts to address this issue by investigating the role of top-down factors in Korean speakers’ predictive processing of honorific agreement. Two visual-world eye-tracking experiments were conducted, analyzing participants’ anticipatory eye movements while manipulating two top-down f…
Grammar Searches for Wh‐Questions in Beginning‐Level Child Second Language Learners
It is important for learners to be able to ask wh ‐questions in interaction. However, making wh ‐questions can be difficult for beginning‐level EFL leaners, particularly for those learners whose L1 and L2 differ in the way wh ‐questions are formed. Based on this point, we investigated the grammar searches of such EFL learners for wh ‐questions in interaction, using both conversation analysis (CA) and phonetic analysis. Sixty‐four beginning‐level …
Prediction of there -associated nouns based on verbs in expletive sentences
This study examines the effects of cue validity, proficiency, and immersion experience on the predictive processing of there -associated nouns in expletive sentences. A visual-world eye-tracking task manipulated the validity of the predictive cue by varying verb number (singular; plural) and aspect (simple; perfect): For example, There {is/are/has been/have been} just {one apple/two apples}. The results show that both L1 speakers and L2 learners …
Generative AI is useful for second language writing, but when, why, and for how long do learners use it
Numerous studies have highlighted the benefits of recent advancements in generative artificial intelligence (AI) technology for second language (L2) writing. However, most of these studies have relied on pretest/posttest designs or interview/questionnaire methods that reflect the researchers’ perspectives. To expand the research on this topic, we take two approaches. Firstly, we investigate how L2 learners of English utilize ChatGPT in a writing …
The Impact of Subordination Type and Finiteness on Second Language Development in Timed Impromptu Writing
The use of subordination enables language users to achieve syntactic efficiency by allowing them to connect ideas in temporal/logical relation. Although the importance of subordination has been recognized in previous research on second language (L2) writing, it has been typically assessed with global indices that measure overall ratio of subordination. In order to capture more nuanced patterns in the development of L2 writing, this study measures…
Sensitivity to honorific agreement
Language processing involves active engagement with linguistic cues to predict future information while integrating available information in a bottom-up manner. Recent research in this area suggests that individual differences play a role in predictive processing. However, the exact ways in which individual factors contribute to these differences remain a topic that warrants further investigation. Additionally, most previous studies in this area …
Growth of lexical and syntactic complexity, accuracy, and fluency in spoken production of first language and second language children
Complexity, accuracy, and fluency (CAF) research has largely focused on competition among the three constructs and their relationship with proficiency. However, it is largely unknown how CAF develops in the course of language acquisition, particularly in children. Furthermore, each construct has been treated as a unified phenomenon rather than as multidimensional. This study thus aims to examine developmental patterns of CAF in spoken production …
Learning contexts and proficiency matter
This study investigates L2 learners’ sensitivity to conventional and unconventional dative constructions in English. Experiment 1 focused on measuring EFL learners’ acceptability judgment and real-time processing of sentences containing both types of constructions. Experiment 2, involving ESL learners, aimed to explore the modulating effects of L2 learning contexts and proficiency. Results from Experiment 1 indicated that EFL learners demonstrate…
Effects of Lexical Frequency in Predictive Processing
This study explores how word frequency affects verb-mediated prediction in L1 and L2 speakers, using a visual-world eye-tracking task. By manipulating frequency of nouns within subjects (higher; lower) and type of verbs used as predictive cues (semantically restrictive; neutral) in sentences (e.g., The {doctor/surgeon} {opened/moved} the box), we investigated the impact of frequency of early-processed words on prediction, hypothesizing that highe…
Wanna contraction in first language acquisition, child second language acquisition, and adult second language acquisition
Contraction of want to to wanna is sometimes possible (e.g., Who do you want to/wanna stay with ___ ? ), but sometimes impossible (e.g., Who do you want ___ to/*wanna stay? ). This contrast is attributable to the grammatical constraint that a wh -trace blocks the contraction of want and to . Most first language (L1) and second language (L2) acquisition studies testing learner knowledge of this constraint have used elicited production tasks and fo…
Korean Syntactic Complexity Analyzer (Kosca)
Given the lack of computational tools available for assessing second language (L2) production in Korean, this study introduces a novel automated tool called the Korean Syntactic Complexity Analyzer (KOSCA) for measuring syntactic complexity in L2 Korean production. As an open-source graphic user interface (GUI) developed in Python, KOSCA provides seven indices of syntactic complexity, including traditional and Korean-specific ones. Its validity w…
Effects of pronominal reference on the integration of syntactic and semantic information in second language processing
This study investigated the effect of pronominal reference on the integration of syntactic and semantic information in second language (L2) processing. We conducted a self‐paced reading task involving 60 adult Korean‐speaking learners of English and 44 native English speakers. The experiment manipulated the semantic congruity between a subject and its adjectival predicate, as well as the reference type (pronoun vs. full noun) within the interveni…
Development of morphological diversity in second language Korean
Automatic Analysis of Constructional Diversity as a Predictor of EFL Students’ Writing Proficiency
One of the important components in second language (L2) development is to produce clause-level units of form–meaning pairings or argument structure constructions. Based on the usage-based constructionist approach that language development entails an ability to use more diverse, more complex, and less frequent constructions, this study tested whether constructional diversity and complexity predict L2 learners’ writing proficiency. Using a natural …
Sensitivity to syntactic dependency formation in child second language processing
This study investigates whether child second language (L2) learners can use syntactic information during the processing of sentences involving unbounded dependencies and how their processing patterns compare to those of child monolinguals and adult L2 learners. Through a self-paced reading experiment involving the numeral quantifier (NQ) construction in Korean, we tested participants’ sensitivity to agreement violations between a noun phrase (NP)…
Do position and lexical knowledge matter in children’s second language speech perception
Assessing Verb-Construction Integration in Young Learners of English as a Foreign Language
Extending previous findings on adult L2 learners' integration of verbal and constructional information, this study investigated how child learners of English as a foreign language produce verbs in target constructions and whether (a) receptive skills and (b) the specific production modality (spoken versus written) modulate the integration process. Written and spoken samples from 76 Korean-speaking children were analyzed for verb-construction asso…
Integration of Verbal and Constructional Information in the Second Language Processing of English Dative Constructions
This study investigated the effects of construction types on Korean-L1 English-L2 learners’ verb–construction integration in online processing by presenting the ditransitive and prepositional dative constructions and manipulating the verb’s association strength within these constructions. Results of a self-paced reading experiment showed that the L2 group spent longer times in the verb–construction integration in the postverbal complement region …

Effects of Written Versus Spoken Production Modalities on Syntactic Complexity Measures in Beginning‐Level Child EFL Learners
Learner corpus studies using syntactic complexity as a construct for characterizing learner proficiency have found that higher proficiency permits learners to produce more complex syntactic structures. However, the majority of previous studies have focused on writing, almost exclusively with adult second language (L2) learners. Given the fundamentally different mechanisms underlying speaking and writing activities, this study investigated (a) how…
