Relative clauses (RCs) are complex syntactic structures because they consist of multiple clauses and involve syntactic movement. RCs are known as a reliable clinical marker of syntactic impairment across many different languages and populations. Children with autism spectrum disorders (ASD) struggle with the comprehension and production of RCs,…

The most recent studies on the acquisition of evidentiality, be it morphologically or syntactically encoded, have argued that the comprehension lag detected is due to factors having to do with others' authority or mental perspective, where "others" stands for other individuals involved in the experiment in various manners (e.g., the…

This article investigates how children acquire word order generalizations from ambiguous and infrequent input. We focus on verb placement in Norwegian relative and complement clauses. In two elicitation experiments we explore where children (age 3-7) place verbs in three embedded clauses types: one requiring a purely syntactic generalization and…

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.…

The acquisition of passives is well-studied in many languages, with evidence of crosslinguistic differences in the age at which passives are acquired. The aim of this study is to add to the existing knowledge of child acquisition of passives by providing data from Afrikaans and isiXhosa, two under-researched and typologically different languages…

Arabic is characterized by diglossia, which involves the use of two language varieties within a single speech community: Spoken Arabic (SpA) for everyday speech and Modern Standard Arabic (MSA) for formal speech and reading/writing. Earlier research suggests that some Arabic-speaking children with Autism spectrum disorder (ASD) might favor MSA…

This study addresses the question of how the main factors related to input--including the environment in which children are exposed to both languages, the relative timing of the onset of the exposure to them and the amount of input--affect bilingual language acquisition at primary-school age. We examined the data of 42 German Polish bilinguals who…

Italian relative clauses like "Il bambino che bacia la mamma" 'the child that kisses the mom' are ambiguous between a subject reading and an object reading with postverbal subject. However, the latter is scarcely accessible for word order and theory-internal considerations. This study aims at investigating the role of semantic…

Previous research indicates that the development of mood selection in Spanish spans several years and ends in the mastery of mood selection with sentential complements to express complex semantic meanings. The present study investigates this underexplored late stage by examining how Spanish-speaking children acquire adultlike mood selection in…

Quantificational elements such as some pose a challenge to young language learners, given their vague meaning and ability to take on an upper-bounded interpretation (relative to "all") in certain contexts. The challenge is enhanced when a child is acquiring multiple languages that do not share a one-to-one mapping between their lexical…

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…

We present a series of experiments investigating English-speaking children's comprehension of "it"-clefts and "wh"-pseudoclefts. Previous developmental work has found children to have asymmetric difficulties interpreting object clefts. We show that these difficulties disappear when clefts are presented in felicitous contexts,…

Very few studies exist on the role of cross-language similarities in cognate word acquisition. Here we sought to explore, for the first time, the interplay of orthography (O) and phonology (P) during the early stages of cognate word acquisition, looking at children and adults with the same level of foreign language proficiency and by using two…

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…

Through examining all instances of the nontarget "be" before verbs in the written interlanguage of Chinese learners at different proficiency levels, the present study reveals that nontarget "be" performs different functions, and there is a function shift from low to high proficiency levels. At the lowest levels, "be"…
