Recent studies in the second language acquisition of negation have focused on polarity items and their licensing contexts. Although several studies show a correlation between higher degrees of second language (L2) proficiency and the acquisition of the target L2 structures, less attention has been given to the relation between the acquisition of…

Given the rich bound morphology of Spoken Arabic, an attempt was made here to construct a developmental measure corresponding to the mean length utterance (MLU) in English and to morpheme-per-utterance (MPU) in Hebrew. The adaptation to Arabic resulted in a new measurement termed Arabic-MPU, that was experimentally tested on a sample of 98…

This study investigated the relative contributions of English morphological and vocabulary knowledge to second language (L2) reading comprehension among 100 adult Japanese English as a foreign language (EFL) learners. The study also investigated the extent to which the roles of morphological and vocabulary knowledge in L2 reading comprehension…

In English, a sentence like "The cat didn't eat the carrot or the pepper" typically receives a "neither" interpretation; in Japanese it receives a "not this or not that" interpretation. These two interpretations are in a subset/superset relation, such that the "neither" interpretation (strong reading)…

As one type of the most extensively used sentences, English questions are must-learn grammatical structures for learners of English as a foreign language (EFL). However, it is commonly seen that English learners across proficiency levels produce ungrammatical English questions. To determine the source of learners' erroneous production, we…

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…

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…

The present study investigates whether or not Thai students' English writing skills can be improved by using an online grammar checker. First, typical syntactic errors made by undergraduate students majoring in English and English for Careers were examined. Secondly, possible reasons for syntactic errors in English writing in the light of Lado's…

Purpose: In this letter, the authors respond to Pavelko and Owens' (2017) newly advanced set of procedures for language sample analysis: Sampling Utterances and Grammatical Analysis Revised (SUGAR). Method: The authors contrast some of the new guidelines for transcription, morpheme segmentation, and language sample elicitation in SUGAR with…

Purpose: This study examined the production of morphosyntactic markers by school-age children with and without developmental language disorder. Comparisons were made between students who speak mainstream American English (MAE) dialects and nonmainstream American English (NMAE) dialects. Method: First- and second-grade students (N = 82) completed…

Background: Grammatical morphology has been shown to be problematic for children with specific language impairment (SLI) or developmental language disorder (DLD). Most research on this topic comes from widely spoken languages, such as English. Despite Welsh being the most extensively spoken indigenous in the UK after English, and Wales being the…

Background: Middle school students use the information conveyed by morphemes (i.e., units of meaning such as prefixes, root words and suffixes) in different ways to support their literacy endeavours, suggesting the likelihood that morphological knowledge is multidimensional. This has important implications for assessment. Methods: The current…

Purpose: Children with developmental language disorder sometimes spontaneously repeat clinician models of morphemes targeted for treatment. We examine how spontaneous repeating of clinician models in the form of recasts associates with improved child production of those emerging morphemes. Method: Forty-seven preschool children with developmental…

The Bottleneck Hypothesis argues that properties of inflectional morphology explain why second-language learners may face persistent difficulties in articulating meaning in target-language forms. In particular, the acquisition task proves even harder when first and second languages differ in the way they organize the mapping of functional features…
