Comprehension of sentences with a center-embedded, object-gapped relative clause (ORC) is challenging for children as well as adults. Mismatching lexical and grammatical features of subject noun phrases (NPs) across the main clause and relative clause has been shown to facilitate comprehension. Adani et al. concluded that children's comprehension…

The cross-categorical use of nouns and verbs poses a challenging problem to young language learners because they are known to be less willing to accept that a single form of a word be used for more than one linguistic purpose (e.g., one-form/one-function principle). The present study investigated whether children under 3 years of age are able to…

This study investigates the probable effect of a digital game-based vocabulary learning (DGBVL) task on the acquisition of some components of a word knowledge framework. In so doing, 124 Persian speakers (56 males and 68 females) were randomly assigned to either a control or an experimental group. The experimental group participants completed a…

The current study investigated the extent to which L2 learners' productive vocabulary knowledge could predict multiple dimensions of spontaneous speech production. A total of 39 English as a foreign language (EFL) participants with varying L2 proficiency levels first completed a productive vocabulary knowledge task (Lex30). Their spontaneous…

We examined sources of morphological variability in second language (L2) learners of Spanish whose native language (L1) is English, with a focus on L1-L2 similarity, morphological markedness, and knowledge type (receptive vs. expressive). Experiment 1 uses event-related potentials to examine noun-adjective number (present in L1) and gender…

This study investigated how forty-six mothers modified their talk about familiar and unfamiliar nouns and verbs when interacting with their children with Down Syndrome (DS), language impairment (LI), or typical development (TD). Children (MLUs < 2·7) were group-matched on expressive vocabulary size. Mother-child dyads were recorded playing with…

This study investigated cross-linguistic influence in acquisition of a second lexicon, evaluating Samoan-English sequentially bilingual children (initial mean age 4 ; 9) during their first 18 months of school. Receptive and Expressive Vocabulary tasks evaluated acquisition of four word types: cognates, matched nouns, phrasal nouns and holonyms.…

So far, the comprehension and production language modes have typically been studied separately in generative second language acquisition research, with the focus shifting from one to the other. This article revisits the asymmetric relationship between comprehension and production by examining the second language (L2) acquisition of the noun phrase…

Mastery of grammatical gender is difficult to achieve in a second language (L2). This study investigates whether persistent difficulty with grammatical gender often observed in the speech of otherwise highly proficient L2 learners is best characterized as a production-specific performance problem, or as difficulty with the retrieval of gender…

Background: Naming accuracy for nouns and verbs in aphasia can vary across different elicitation contexts, for example, simple picture naming, composite picture description, narratives, and conversation. For some people with aphasia, naming may be more accurate to simple pictures as opposed to naming in spontaneous, connected speech; for others,…
