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…

While the role of task repetition has received much attention in task-based research, few studies have examined how exact task repetition affects the performance of child second language learners. Also, little is known about the impact of exact task repetition on trade-off effects between linguistic performance areas among child learners. To help…

Building up on Munro and Derwing, the current study set out to re-examine and generalize the Functional Load (FL) principle (Brown, 1988) as a tool to identify a set of relatively crucial segmental features for successful understanding in L2 communication. In Experiment 1, 40 Japanese learners of English in English-as-Foreign-Language settings…

This study investigated how adult second language (L2) learners of Mandarin Chinese use knowledge of phonological and lexical statistical regularities when acoustic information is insufficient for word recognition. A gating task was used to test intermediate L2 learners at two time points across a semester of classroom learning. Native Mandarin…

Recent ERP research with adults has shown that the online processing of subject-verb (S-V) agreement violations is mediated by the relative perceptual salience of the violation (Dube et al. 2016). These findings corroborate infant perception research, which has also shown that perceptual salience influences infants' sensitivity to grammatical…

This study investigated the effects of task complexity on child learners' second language (L2) gains, the relationship between aptitude and L2 development, and the extent to which task complexity influences this relationship when recasts are provided. Sixty child EFL learners were assigned to two experimental groups. During the treatment, one…

Oral narrative retells are rich sources of information for language development. Investigators collected English-language oral narrative retells during the fall and spring from 65 Spanish-English-speaking dual language learners (DLL) in kindergarten and first grade. Investigators examined transcripts of oral narratives for (a) inclusion and…

This study examines heritage speakers' knowledge of Standard Arabic (SA) and compares their patterns of SA acquisition to those of learners of SA as second/foreign language (L2). In addition, the study examines the influence of previously acquired language varieties, including Colloquial Arabic (QA), on SA acquisition. To this end, the study…

Background: Deafness has an adverse impact on children's ability to acquire spoken languages. Signed languages offer a more accessible input for deaf children, but because the vast majority are born to hearing parents who do not sign, their early exposure to sign language is limited. Deaf children as a whole are therefore at high risk of language…

This study examined whether type of early language experience provides advantages to heritage speakers over second language (L2) learners with morphology, and investigated knowledge of gender agreement and its interaction with diminutive formation. Diminutives are a hallmark of Child Directed Speech in early language development and a highly…

We investigated the consequences of bilingualism for verbal fluency by comparing bilinguals to monolinguals, and dominant versus non-dominant-language fluency. In Experiment 1, bilinguals produced fewer correct responses, slower first response times and proportionally delayed retrieval, relative to monolinguals. In Experiment 2, similar results…

This study assessed, in a sample of 98 adult native speakers of Dutch, how their lexical skills and their speaking proficiency varied as a function of their age and level of education and profession (EP). Participants, categorized in terms of their age (18-35, 36-50, and 51-76 years old) and the level of their EP (low versus high), were tested on…

This study investigated how English as a foreign language (EFL) learners' types of language for thinking and types of oral elicitation tasks influence their lexical collocational errors in speech. Data were collected from 42 English majors in Taiwan using two instruments: (1) 3 oral elicitation tasks and (2) an inner speech questionnaire. The…

This paper investigates the extent to which productive use of formulaic sequences by intermediate students of two typologically different languages, i.e., English and Spanish, is associated with their oral proficiency in these languages. Previous research (e.g., Boers et al., "Language Teaching Research" 10: 245-261, 2006) has shown that…

This dissertation tests a grammatical structure, differential object marking (DOM), which is particularly difficult for L2 learners to acquire. DOM is a phenomenon in which some direct objects are morphologically marked to distinguish them from subjects (Comrie, 1979). In Spanish, animate and specific direct objects are marked with the preposition…
