In this study, we investigated crosslinguistic influence (CLI) at developmental stages of third language (L3) acquisition of English by Russian--Norwegian children (N = 31). We tested seven linguistic properties within three linguistic modules (morphology, syntax and syntax-semantics). We compared the L3 learners to Norwegian (N = 90) and Russian…

Cross-linguistically, monolingual children produce target-like inflected verbs much earlier than they can reliably distinguish between singular and plural subject-verb agreement morphology in comprehension (i.e. Johnson, V., J. de Villiers, and H. Seymour. 2005. "Agreement Without Understanding? The Case of Third Person Singular /s/."…

This study examines the extent to which extra-linguistic factors such as language dominance, order of acquisition and language of instruction are deterministic for multilingual transfer selection and subsequent development. We test two groups of Catalan-Spanish bilinguals acquiring English as an L3 in a controlled setting. We first examine…

Purpose: This study compared and characterized the tense and agreement productivity of boys with fragile X syndrome (FXS), children with developmental language disorder (DLD), and children with typical development (TD) matched on mean length of utterance. Method: Twenty-two boys with FXS (M[subscript age] = 12.22 years), 19 children with DLD…

Purpose: The purpose of this assessment-focused clinical focus article is to increase familiarity with African American English (AAE)-speaking children's pattern of language use in third-person singular contexts and to discuss implications for speech-language assessments of developing AAE-speaking children. Method: The clinical focus draws on…

This study considers the performance of tone pronunciation and morpheme intelligibility by L2 Polish Mandarin learners. A mixed-effects ordinal regression model and Tukey's HSD multiple test were used to examine the start-point, end-point, of syllables as a means of assessing their intelligibility by L2 Polish learners regarding the tones with the…

Nowadays, theoretic and empirical research into affix acquisition in Second Language Acquisition has attracted increasing attention (Peng Tingting, 2009; Zhao Ming, 2014; Chen Jie, 2017). However, there are still few empirical studies on affix acquisition of Chinese English learners, especially from the perspective of corpus linguistics. The…

In this article we explore the ways in which academic citation practices have changed over the past 50 years. Based on the analysis of a corpus of 2.2 million words from the same leading journals in four disciplines in 1965, 1985, and 2015, we document a substantial rise in citations over the period, particularly in applied linguistics and…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

This article investigates whether explicit instruction can affect second language (L2) competence in the domain of English quantifier scope. An intervention study was conducted with L1-Mandarin L2-English learners in order to examine (1) whether these learners can learn inverse scope for the structure on which they are instructed…

In this study, we examined the accuracy and consistency of Greek-speaking children with spelling difficulties using a spelling level-matched design at two time points. Eighty-seven children were selected for inclusion in three groups: a group with spelling difficulties (SpD, n = 22 fifth graders) and two control groups, a chronological age-matched…

This paper investigates how negation develops in the speech of a Turkish-speaking child in the very early stages of language acquisition. The study features the video recordings of a child between the ages of 19 and 22 months and the analyses of negative forms in the recorded data. The development of negation in parent-child interactions is…

Evidentiality in language marks how information contained in a sentence was acquired. For instance, Turkish has two past-tense morphemes that mark whether access to information was direct (typically, perception) or indirect (hearsay/inference). Full acquisition of evidential systems appears to be a late achievement cross-linguistically. Currently,…

Purpose: The goal of this study was to investigate the extent to which sample length affected the reliability of total number of words (TNW), number of different words (NDW), and mean length of C-units in morphemes (MLCUm) in parent-elicited conversational samples for 3-year-olds. Method: Participants were sixty 3-year-olds. A 22-min language…

Purpose: The aim of the study was to evaluate the efficacy of a theoretically motivated explicit intervention approach to improve regular past tense marking for early school-age children with developmental language disorder (DLD). Method: Twenty-one children with DLD (ages 5;9-6;9 [years;months]) were included in a crossover randomized controlled…
