This study documents the effects of social inequality on different dimensions of lexical comprehension in Spanish-speaking Argentinian toddlers, a population in which socioeconomic differences are more striking than in previously studied populations. Using a performance-based forced-choice lexical recognition task implemented on a tablet, an…

This research investigates selectivity in word learning for bilingual infants. Previous work demonstrated that bilingual infants show greater openness to non-native language sounds in object labels than monolinguals (Hay et al., 2015; Singh, 2018). It remains unclear whether bilingual openness extends to nonspeech sounds. We presented 14- and…

In this study, we use temporally aligned word embeddings and a large diachronic corpus of English to quantify language change in a data-driven, scalable way, which is grounded in language use. We show a unique and reliable relation between measures of language change and age of acquisition ("AoA") while controlling for frequency,…

This investigation examined the existence of interconnectedness between developing linguistic subsystems. Spontaneous speech samples were collected from 31 typically-developing Greek-speaking toddlers across two age levels, at 28 and 36 months. Correlational analyses were performed synchronically and predictively, revealing significant positive…

Each language has its unique way to mark grammatical information such as gender, number and tense. For example, English marks number and tense/aspect information with morphological suffixes (e.g., -"s" or -"ed"). These morphological suffixes are crucial for language acquisition as they are the basic building blocks of syntax,…

Iterated language learning experiments that explore the emergence of linguistic structure in the laboratory vary considerably in methodological implementation, limiting the generalizability of findings. Most studies also restrict themselves to exploring the emergence of combinatorial and compositional structure in isolation. Here, we use a novel…

The aim of the current systematic review and meta-analysis is to comprehensively synthesize the effectiveness of language promotion interventions in early childhood education and care (ECEC) settings on L1 and L2 development of dual language learners (DLLs). We will use the PICOC-Strategy (Population, Intervention, Comparison, Outcome, Context)…

During the second year of life, children acquire words and expand their receptive and expressive vocabularies at a rapid pace. At this age, toddlers' phonological abilities are also developing rapidly. The current study investigated the effect of phonological complexity of words on the order in which they are acquired, receptively and…

The present study examined language trajectories and placement outcomes for children with autism spectrum disorder (ASD) receiving early intensive behavioral intervention (EIBI). Language measures were collected at baseline and 6, 12, 18, 24, and 36 months or until exit from EIBI in 131 children with ASD. Growth models estimated overall and…

This study is based on naturalistic speech samples produced by one child learning Cree as her first language (2;01-4;03) and presents the first investigation into the development of preverbs in the language. Preverbs are an optional class of morpheme which precede the lexical verb stem, dividing into grammatical, lexical and directional (deictic)…

For children with complex communication needs in the early stages of language development, access to appropriate vocabulary provides a means for social interaction and participation, and the foundation for the acquisition of grammar and other language related skills. While numerous resources are available to support decision making for speakers of…

This present research analyses the linguistic environmental setting in homes of children under the age of two years from different social groups and looks at the extent to which the speech from other children contributes to shaping that environment. The corpus includes recordings of spontaneous speech from middle-class households in residential…

The Comprehensive Assessment System (CAS) Framework presents a vision for a system of assessments for English Learners in secondary grades that brings assessment closer to the classroom and fully involves teachers in assessment development and validation. The CAS Framework is intended to signal a new and equitable direction and to provoke…

The question of why native and foreign languages are learned with a large performance gap has prompted language researchers to hypothesize that they are subserved by fundamentally different mechanisms. However, this hypothesis may not have taken into account that these languages can be learned under different conditions (e.g., naturalistic vs.…

The purpose of the current investigation is to analyze extant research examining the impact of play therapy on the development of language skills in young children with autism spectrum disorder (ASD). As rates of ASD diagnoses continue to increase, families and educators are faced with making critical decisions regarding the selection and…
