What the literature leaves open

  • the study only analyzed the impact of ENRICH on linguistic aspects of educator-toddler interactions, - the study did not examine the long-term effects of ENRICH on children's language development, - the sample size was limited to 24 early childhood classrooms, - the study did not control for other factors that may influence the effectiveness of ENRICH

  • examining the long-term effects of ENRICH on children's language development, - investigating the effectiveness of ENRICH in different cultural and socioeconomic contexts, - exploring the impact of ENRICH on other aspects of child development, such as socioemotional and cognitive development

  • Investigate the development of directive strategies in both bilingual and monolingual children with pronoun reversals. Examine the interaction of discourse-functional, usage-based, and crosslinguistic factors in the development of want-constructions. Conduct standardized developmental or language assessments to rule out subtle developmental differences.

    Want-Constructions as Non-Canonical Imperatives: A Case Study of a Bilingual English–Russian Child with Pronoun Reversal · 2026 · DOI

  • The existing research has not examined the use of want-constructions in bilingual children with pronoun reversal. There is a need to investigate the development of directive strategies in both bilingual and monolingual children with pronoun reversals. The study fills a gap in the existing research by examining the morphosyntactic forms and discourse-pragmatic functions of want-constructions in a bilingual English-Russian child with pronoun reversal.

  • The impact of multilingualism on autistic children's development is not well understood. There is a lack of studies investigating the relationship between multilingualism and verbal fluency in autistic children. The paper aims to fill this gap by exploring the effect of multilingualism on lexical-semantic abilities in autistic children.

    Multilingual exposure and lexical–executive abilities underlying verbal fluency: A study of children with and without autism · 2026 · DOI

  • Use of Spanish in the home by parents/caregivers has been studied in relation to Latine children’s Spanish oral language skills, yet relatively little is known about the cultural factors that shape these skills in early childhood.

  • Developmental language disorder (DLD) is among the most common childhood conditions, yet little is known about age- and institution-related differences in participation among children with DLD.

  • This is a route to answering the biggest open questions about how human minds work, and with that understanding, making AI that positively impacts mental health, education, and society in ways unlikely to come from machine learning alone.

    Language Is Not All You Need … but Language, Probabilistic Programs & Bayesian Models of Cognition Will Get You Pretty Far · 2026 · DOI

  • Evidence remains limited and largely focused on in-service PD, highlighting the need for stronger integration of CLRP and sustained PBL opportunities in future professional learning.

    Professional Learning for Young Dual Language Learners With Disabilities: A Review Study · 2026 · DOI

  • In this review, we examine Middle Eastern (ME) IDS—an underexplored area in cross-cultural research—by comparing it with Western IDS across prosodic, phonological, lexical, syntactic, and pragmatic modifications.

    Beyond the WEIRD Lens: Infant-directed speech across Middle Eastern contexts · 2026 · DOI

  • Abstract Overhearable speech constitutes over half of children's language exposure, but its role in language development remains underexplored.

    Developmental change in acquiring overhearable words from naturalistic contexts · 2026 · DOI

  • However, how the newborn brain processes speech envelopes and how brief exposure to them affects post-stimulation neural activity remain unclear.

    Neural processing of speech envelopes from different languages and post-stimulation functional connectivity in newborns: an fNIRS study · 2026 · DOI

  • Our analyses suggest a mechanism through which experiences with poverty may disrupt early language development, although further exploration of the impacts of family dynamics within this crucial developmental period is warranted.

    Modeling the mechanisms through which conditions of poverty are associated with late language emergence in young children · 2025 · DOI

  • However, the factors that affect the relative acquisition trajectories of these categories remains unclear.

    Content-Form Interaction in the Acquisition of Temporal Markers by Mandarin-Speaking Children · 2024 · DOI

  • However, some have argued that language development unfolds similarly across environmental contexts, including those in which childdirected language is scarce.

    Infants who are rarely spoken to nevertheless understand many words · 2024 · DOI

  • The application of Non-linear Phonology to Spanish remains limited. There is a need to delineate boundaries between typical and protracted phonological development.

    Development of word and syllable structure in Chilean children with typical and protracted phonological development · 2026 · DOI

  • Future research should also consider other dimensions of syllabic production and include complementary indicators, such as Whole Word Match or Percentage of Consonants Correct, to expand multidimensional analysis of PPD in Chilean Spanish.

  • The automated method used for extracting classifiers and associated nouns may have potential accuracy trade-offs. Chinese texts pose challenges to parsers due to the lack of unambiguous word boundaries.
