Negation is a cornerstone of human language and one of the few universals found in all languages. Without negation, neither categorization nor efficient communication would be possible. Languages, however, differ remarkably in how they express negation. It is yet widely unknown how the way negation is marked influences the acquisition process of…

Ferhat Karaman; Jill Lany; Jessica F. Hay – Cognitive Science, 2024
Infants are sensitive to statistics in spoken language that aid word-form segmentation and immediate mapping to referents. However, it is not clear whether this sensitivity influences the formation and retention of word-referent mappings across a delay, two real-world challenges that learners must overcome. We tested how the timing of referent…

Lauren Berger; Jennie Pyers; Amy Lieberman; Naomi Caselli – Language Acquisition: A Journal of Developmental Linguistics, 2024
Most deaf children have hearing parents who do not know a sign language at birth and are at risk of limited language input during early childhood. Studying these children as they learn a sign language has revealed that timing of first-language exposure critically shapes language outcomes. But the input deaf children receive in their first language…

This article explores the applicability of mean length of utterance (MLU) as a language assessment measure for Georgian child language, as to-date, Georgian, a morphologically rich language with numerous inflectional categories, experiences an extensive lack of instruments for early language assessment. To this end, a set of guidelines for…

Joan Birulés; Ferran Pons; Laura Bosch – International Journal of Behavioral Development, 2024
Successful language learning in bilinguals requires the differentiation of two language systems. The capacity to discriminate rhythmically close languages has been reported in 4-month-olds using auditory-only stimuli. This research offers a novel perspective on early language discrimination using audiovisual material. Monolingual and bilingual…

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 qualitative ethnographic research explores baby talk (BT) and ontology of infancy in a small, rural Indo-Fijian community via semistructured interviews with mothers about their children's language learning, mothers' narratives about their photographs of their young children engaged in everyday language, and audio- and video-recordings of…

This article evaluates the acquisition of directionals in Q'anjob'al, a Western Mayan language of Guatemala. The data come from a longitudinal study of two Q'anjob'al monolingual children of Santa Eulalia, Huehuetenango, Guatemala: Xhuw (1;9-2;5) and Xhim (2;3-3;5). The results show how these children acquire the morphological distribution of…

In low- and middle-income countries, urbanization has spurred the expansion of peri-urban communities, or urban communities of formerly rural residents with low socioeconomic status. The growth of these communities offers researchers an opportunity to measure the associations between the level of urbanization and the home language environment…

Infants' preference for vowelharmony (VH, a phonotactic constraint that requires vowels in a word to be featurally similar) is thought to be language-specific: Monolingual infants learning VH languages show a listening preference for VH patterns by 6 months of age, while those learning non-VH languages do not (Gonzalez-Gomez et al., 2019; Van…

Research suggests that girls acquire language faster than boys, with gender differences most pronounced in vocabulary acquisition during early childhood. This study examines the role of gender in the acquisition of vocabulary and morphosyntax in Palestinian Arabic-speaking children aged 18 to 36 months. Using the Palestinian Arabic Communicative…

Crossing the Boundary: No Catastrophic Limits on Infants' Capacity to Represent Linguistic Sequences
Natalia Reoyo-Serrano; Anastasia Dimakou; Chiara Nascimben; Tamara Bastianello; Daniela Lucangeli; Silvia Benavides-Varela – Developmental Science, 2025
The boundary effect, namely the infants' failures to compare small and large numerosities, is well documented in studies using visual stimuli. The prevailing explanation is that the numerical system used to process sets up to 3 is incompatible with the system employed for numbers >3. This study investigates the boundary effect in 10-month-old…

Guro S. Sjuls – Infant and Child Development, 2025
Studying early language development has been a challenging task throughout the years. Earlier studies mostly documented language competence only after toddlers had started producing their first words. Theoretical and methodological advances in this domain brought about more sophisticated ways of probing into early development by exploiting overt…

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…

We Learn Together is a 20-week, low-cost infant/toddler school-readiness intervention developed to provide instructional content and supportive tools for teachers to be more explicit and intentional in interactions with children to support early development. Short-term effects were established in a previously published real-world effectiveness…
