All communication systems rely on sets of rules that must generally be followed for successful communication to be possible; in the case of human language, these rules are given by the grammar. However, despite these rules, there is considerable variation that has been noted across the grammar. In this dissertation, I explore one understudied…

Purpose: Measures of grammatical accuracy are effective measures of children's language skills. However, many measures, such as percent grammatical utterances, were developed for children who speak General American English (GAE) and, therefore, may not be appropriate for students who speak other dialects. This study examines different scoring…

Background and aims: Narrative-based language intervention provides a naturalistic context for targeting overall story structure and specific syntactic goals in children with Developmental Language Disorder (DLD). Given the cognitive demands of narratives, narrative-based language intervention also has the potential to positively impact related…

Purpose: In spite of improvements in language outcomes for children with hearing loss (HL) arising from cochlear implants (CIs), these children can falter when it comes to academic achievement, especially in higher grades. Given that writing becomes increasingly relevant to educational pursuits as children progress through school, this study…

This study investigates the knowledge of bilingual speakers of Catalan and Spanish regarding the production of object pronominal clitics (excluding non-reflexive third-person clitics), with a focus on: (i) their morphology, considering the variants that coexist for each form, and (ii) their syntactic placement (proclitic or enclitic) with respect…

The present study examined whether early immersive L2 exposure in a foreign language learning context can yield long-term advantages in L2 morpho-syntactic sensitivity. Participants were 40 Korean university students with high English proficiency, who had either attended an English kindergarten or begun learning English in a classroom, and a…

Language is inherently variable, and learner language is particularly variable. The variationist paradigm considers learner language a heterogeneously variable yet inherently rule-governed system. Specifically, learners' alternation between native-like and nonnative-like variants of a variable or invariable target native speaker (NS) form…

This study attempts to explain a systematic phenomenon that has been described in interlanguage grammars crosslinguistically: Null-Prep, which consists of omitting the obligatory preposition in certain movement constructions. We propose that Null-Prep is not related to lack of knowledge of "wh"-movement, as previously assumed, but to…

Conversely to plenty of studies describing how L1 transfer affects L2 systems, where the two grammars, L1/L2, often only come to interact later in life, less is known of dominant language transfer in heritage language grammars. Unlike in L2 speakers, the dominant language of the heritage speaker potentially affects its weaker language already from…

Adult first language (L1) English speakers who are advanced second language (L2) learners of Spanish demonstrate near-ceiling levels of accuracy for some features of Spanish, such as [Person] and [Number] for verbs (McCarthy, 2012; Rodgers, 2011). While for other features, such as [Aspect] for copulas (i.e. ser and estar), and [Person] and…

Over several decades, numerous approaches applied to EFL have resulted in theories and reasonings to teach and learn English. Although Communicative Language Teaching (CLT) is the most commonly used path nowadays, it has only resulted in minimal development of university learners' oral skills; i.e., English-beginner-level students usually attain…

Although a considerable number of studies have shown D(eterminer) elements, i.e. determiners and pronominal clitics, to be particularly vulnerable to impairment in monolingual children with Developmental Language Disorder (DLD), little is known about the use of appropriate or/and grammatically correct referring expressions in the children's…

Purpose: This forum consists of articles that address the need for and approaches to assessment and treatment of morphology and syntax in children. Drawing on papers submitted by diverse laboratories working with multiple populations, this forum includes several articles describing different approaches to treatment, guidelines for goal setting,…

As part of the effort to elevate the oral English proficiency of Thai EFL learners, this paper explores university students' target-deviant English use in conversation, which should be systematically tackled in conversation teaching. Data examined included 41 two-three-minute video-recorded role-play dialogues from two English conversation…

Purpose: Diagnoses, assessments, and treatments, as well as social and language interventions, can be effective in identifying and interpreting specific linguistic features that present special challenges to the language abilities of individuals who are deaf and hard of hearing (DHH). This article reports on a study analyzing complex sentences and…
