Mandarin Chinese verbs are composed of one to four characters that function together as a conceptual unit. However, in modern spoken Chinese, most of these verbs are two-character compounds. This dissertation is focused on adult second language (L2) learners' acquisition of these two-character verb compounds. Specifically, the acquisition of a…

Generative approaches to language have long recognized the natural link between theories of knowledge representation and theories of knowledge acquisition. The basic idea is that the knowledge representations provided by Universal Grammar enable children to acquire language as reliably as they do because these representations highlight the…

This systematic review examines 22 studies (2024-2025) on the use of generative AI, primarily ChatGPT, for providing feedback in English writing instruction for language learners. It identifies the types of feedback AI offers, its effectiveness relative to teacher and peer feedback, and perceptions from students and teachers. Findings show AI…

VocQGen is an automated tool designed to generate multiple-choice cloze (MCC) questions for vocabulary assessment in second language learning contexts. It leverages several natural language processing (NLP) tools and OpenAI's GPT-4 model to produce MCC items quickly from user-specified word lists. To evaluate its effectiveness, we used the first…

This article offers a methodological synthesis spanning 35 years of instructed second language acquisition research on the efficacy of form-focused instruction. Eighty-eight (quasi-) experimental studies were sampled from six academic journals: "Applied Linguistics," "Language Learning," "Language Teaching Research,"…

We examined the lexical and grammatical skills of monolingual and bilingual school-age children with autism spectrum disorders (ASD). Thirteen monolingual and thirteen bilingual children with ASD without intellectual disability, were compared on standardized measures of vocabulary and morphology. Findings revealed that bilingual children performed…

The purpose of this study was to explore pre-readers' comprehension of a story with competing character goals. Fifty-eight children in three age groups (2½-3 years; 3-4 years; and 4-5 years) were read a story in which the protagonist's goal was unstated and conflicted with the goal of the secondary character. Understanding of explicit story…

Teaching grammar has always constituted a major part of language education in curricula around the world, although it has also been heavily debated. Most of the debate on grammar teaching focused on the rationales for teaching it, rather than on the linguistic content that should be taught. At the same time, there appears to be a renewed interest…

Using an oral sentence production task, we investigated how preschoolers (N = 28) produce agreement with complex noun phrases and compared their performance to college students (N = 32) to determine whether preschoolers produce agreement patterns that are qualitatively similar to adults'. We also conducted corpus analyses to investigate relevant…

The flipped classroom model (FC), as a new instructional approach, has been implemented by different disciplines over the past few years. However, the use of this model is still in its infancy in the field of foreign language education. The present study explored the efficacy of using the FC model in facilitating the acquisition of grammar among…

Through two elicited production experiments we investigated how preschool Italian-speaking children access the left periphery of the clause with respect to topics in Clitic Left Dislocation (ClLD) structures. Since the discourse conditions of the experiments are felicitous for the production of passives as well, we also investigated children's…

Scholars of language development have long been challenged to understand the development of functional categories. Traditionally, it was assumed that children's language development initially relies on lexical elements, while functional elements become accessible only at later periods; and that it is lexical growth which bootstraps grammatical…

Addressing themes from the Douglas Fir Group's (2016) transdisciplinary framework, this paper bridges boundaries between cognitive and social disciplines by showing how social contextual factors can affect the psycholinguistic development of complexity, accuracy, and fluency (CAF) in learner language. Sociolinguistic and sociocultural frameworks…

This article examines children's comprehension of the "get"-passive relative to the "be"-passive in an attempt to systematically compare the acquisition of both types of passives. It discusses the findings of two experiments (a picture-matching task and an act-out task) with children ages 36. Results from the picture-matching…

Much has been written about the importance of "writing with discipline" in order to increase the readability and, hence, the publishability of manuscripts submitted to journals for consideration for publication. More specifically, empirical evidence has been provided that links American Psychological Association (APA) errors, citation…
