The paper presents the first comprehensive look at the language development of Romani-speaking children from resource-poor Roma communities in several European countries. 250 participants aged 3- to 10-years participated. The experimental tasks assess knowledge in eight key areas of grammar and morphology, including fast mapping of novel items.…

Dative alternation between prepositional and double object datives has been a popular topic in second language (L2) acquisition, but only few studies deal with discourse constraints such as the "given-before-new" principle, or given-new (GN) ordering, which describes the tendency to place given information before new information. The…

The English Resultative Construction (ERC) is a satellite-framed structure with no identical equivalent in Spanish. In a series of studies, we analyzed and compared recognition (acceptability judgment task) and comprehension (sentence comprehension task) of three ERC subtypes with the English Depictive Construction (EDC) (which has a Spanish…

Bilinguals recognize words with shared morphology and phonology cross-linguistically (i.e., cognates) faster than words that do not have these characteristics. Moreover, higher phonological overlap in cognates enhances the effects, which suggests that phonology eases word recognition. However, it is currently unclear whether words compete purely…

The Spanish subjunctive mood (SUBJ) is said to be highly vulnerable in heritage language (HL) acquisition. However, there is little controlled research on HL-speaking children acquiring the various Spanish SUBJ contexts, so we do not have a clear picture of when, how, or why heritage speakers (HSs) develop in the SUBJ as they do. This study tests…

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…

Resultative constructions show a wide range of cross-linguistic variation, which may pose nontrivial challenges to L2 learners. This study investigates how syntactic and semantic differences between L1 and L2 affect L2 acquisition of resultatives. In particular, we investigate how L1-Korean learners project the syntax and semantics of L2-English…

This article focuses on the acquisition of mood in early complement clauses of European Portuguese (EP). Two semantic features are involved in the EP mood system--epistemicity and veridicality. An elicited production task administered to 80 children aged 4 to 9 showed that, even though children use the subjunctive in [-- epistemic] contexts, the…

Is there an ideal time window for language acquisition after which nativelike representation and processing are unattainable? Although this question has been heavily debated, no consensus has been reached. Here, we present evidence for a sensitive period in language development and show that it is specific to grammar. We conducted a masked priming…

This article proposes that second language learners can use indirect positive evidence (IPE) to acquire a phonological grammar that is a subset of their L1 grammar. IPE is evidence from errors in the learner's L1 made by native speakers of the learner's L2. It has been assumed that subset grammars may be acquired using direct or indirect negative…

According to the Interface Hypothesis (IH) (e.g., Tsimpli & Sorace 2006; Sorace 2011), external interfaces are more challenging for L2 learners than internal interfaces. It is not clear, however, if linguistic phenomena associated with external interfaces are necessarily problematic and if internal interfaces are necessarily unproblematic. In…

Children with specific language impairment (SLI) are particularly sensitive to phonological complexity in their language. Their performance drops when there are specific phonological structures or when complexity increases. A nonword repetition (NWR) test, which aims to assess the phonology of bilingual speakers with and without SLI, should…

Identifying specific language impairment (SLI) in bilingual children represents a clinical challenge because of similarities in language behavior between child second language learners and monolinguals with SLI and because of the lack of standardized language tests on bilingual children. This study investigated the relevance of a LITMUS (Language…

The study aims at identifying characteristic phenotypes for children with SLI and children with sensorineural hearing impairment (HI) in language and in domains associated with language. We focus on verbal agreement inflection and phonological short-term memory, phenomena that have been repeatedly found to be impaired in both groups of children. A…

Language acquisition involves learning not only grammatical rules and a lexicon but also what people are intending to convey with their utterances: the semantic/pragmatic component of language. In this article we separate the contributions of linguistic development and cognitive maturity to the acquisition of the semantic/pragmatic component of…
