This study focuses on parental use of parentese: the acoustically exaggerated, clear, and higher-pitched speech produced by adults across cultures when they address infants. While previous research shows that parentese enhances language learning and processing, it is still unclear what drives the variability in the amount of parental parentese…

Vocabulary size is a crucial early indicator of language development, for both monolingual and bilingual children. Assessing vocabulary in bilingual children is complex because they learn words in two languages, and there remains significant controversy about how to best measure their vocabulary size, especially in relation to monolinguals. This…

This study investigates the interpretation of disjunction words (Italian 'o') in negative sentences by Italian monolingual and bilingual (L1 Italian - L2 English) children and Italian adults. Participants were asked to judge Italian sentences corresponding to the English sentence 'This animal did not eat the carrot or the pepper'. According to the…

In a study comparing executive functions among US Spanish-English bilinguals from low socio-economic (SES) backgrounds to monolinguals of each language, Grote et al. find that bilingual advantages already manifest themselves in pre-school children. This commentary recommends building on this finding, and further investigate the causes underlying…

In this commentary on the Special Issue, I will address the question of what memory spans measure concerning language, as language has, at least, a linear and a hierarchical dimension. I suggest that if anything what is measured has to do with the linear dimension. Then, I will discuss the welcome results on bilingual children with language…

Vocabulary assessment is an important part of measuring language proficiency in both monolingual and bilingual children. The LITMUS Cross-Linguistic Lexical Tasks (CLT) provides a framework for assessing the vocabulary of monolingual and bilingual children using a standardized procedure and comparable stimuli across languages. All language…

This article uses cognitive measures previously developed within linguistic relativity research to explore the thinking patterns of Yucatec Maya-Spanish bilingual children in the Yucatan peninsula. These measures were designed to detect cognitive patterns associated with specific language patterns. Here, these measures are used to test whether 12…

Dutch and German employ voicing contrasts, but Dutch lacks the 'voiced' dorsal plosive /g/. We exploited this accidental phonological gap, measuring the presence of prevoicing and voice onset time durations during speech production to determine (1) whether preliterate bilingual Dutch-German and monolingual Dutch-speaking children aged 3;6-6;0…

In this article, we present an analysis of the complexity of grammatical constraints and their impact on early language acquisition of inflectional morphemes in Malayalam. We use the natural speech production data of two monolingual children acquiring Malayalam between the ages 1;9-2;10 and 2;3-3;0 and three bilingual children acquiring…

Most words spoken to infants are produced in larger units, such as clauses, phrases, and sentences. As such, language learners must recognize words amidst the words that surround them. However, the phonetic forms of words change based on surrounding context. Here, we investigate the effects of a common source of phonetic change--phonological…

This study investigates the influences of early and intense L2 exposure on children's L1 causative verb production, assessed by an experimental causative verb production task. Turkish expresses causality by morphological and lexical means, whereas English does so by periphrastic and lexical means. Learning L2 English might enhance L1 Turkish…

In this study, the authors compare the production of internal codas and branching onsets in four groups of children learning French: monolingual typically-developing children (n = 12), bilingual typically-developing children (n = 61), monolingual children with Specific Language Impairment (n = 17) and bilingual children with Specific Language…

Recent research suggests that bilinguals might exhibit advantages in several areas of executive function, including working memory, inhibitory control, and attentional control. However, few studies have examined potential bilingual advantages within lower socioeconomic status (SES) populations. Here we addressed this gap in the literature by…

Polish and English differ in the surface realization of the underlying Determiner Phrase (DP): Polish lacks an article system, whereas English makes use of articles for both grammatical and pragmatic reasons. This difference has an impact on how referentiality is rendered in both languages. In this article, the authors investigate the use of…

This study explores typically developing bilingual children's performance in their English as a heritage language. The aim of this study is to advance our understanding of heritage language expectations and the role of chronological age and bilingual exposure. A broad range of receptive and expressive linguistic domains are investigated as a…
