Very large numbers words such as "hundred," "thousand," "million," "billion," and "trillion" pose a learning problem for children because they are sparse in everyday speech and children's experience with extremely large quantities is scarce. In this study, we examine when children acquire the…

Background: Prelinguistic communication complexity refers to the use of different communication forms such as eye gaze, gestures and vocalisations and the degree to which these forms are coordinated and how directed to a communication partner. To date, little is known about the relationship between prelinguistic communication complexity and…

Purpose: This study used structural equation modeling to investigate the dimensionality of language in Spanish-English bilingual kindergartners. Five theoretical models were compared, including (a) a unidimensional model; (b) a two-dimensional model by language (Spanish, English); (c) a three-dimensional model by domain of language (phonology,…

This longitudinal study examined early predictors of language development in 74 young children with Autism Spectrum Disorder (ASD) in Taiwan. Participants were assessed twice (initial age between 17 and 35 months) on responding to joint attention (RJA), initiating joint attention (IJA), motor imitation with objects (object imitation; OI) and…

Background: The aim of many interventions used by speech and language therapists (SLTs) is to change behaviours related to communication and interaction. Parent-led language interventions for children in the early years (0-5 years) rely on SLTs supporting parents to change their behaviour in child-focused interactions to effect a change in the…

Purpose: Previously, Lancaster and Camarata (2019) showed that the continuum/spectrum model of the developmental language disorder (DLD) best explained the high heterogeneity of symptoms in children with DLD. We hypothesize that the continuum/spectrum approach can include not only children with DLD but also typically developing (TD) children with…

Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

Objectives: The primary aim was to investigate the variability in language development in children aged 5-7.5 years after bilateral cochlear implantation (CI) up to the age of 2 years, and any impact of the age at implantation and additional noncognitive or anatomical disorders at implantation. Design: Data of 84 congenitally deaf children that…

Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the…

Language development is an important facet of early life. Deaf children may have exposure to various languages and communication modalities, including spoken and visual. Previous research has documented the rate of growth of English skills among young deaf children, but no studies have investigated the rate of ASL acquisition. The current paper…

Computational models of reading have tended to focus on the cognitive requirements of mapping among written, spoken, and meaning representations of individual words in adult readers. Consequently, the alignment of these computational models with behavioural studies of reading development has to date been limited. Models of reading have provided us…

This study used an intrinsic case study to investigate how interventions from applied behavior analysis impacted language development, academic progress, and the reduction of severe challenging behaviors for an 8-year-old child who is Deaf and autistic. 3 main themes were identified: language acquisition, behavioral change strategies, and academic…

The overall interest in the present paper is equal early childhood education (ECE) in terms of educating multilingually. Instead of monoglossic bilingual education directed to some children, or monoglossic monolingual education directed to children despite language background, education for recognising and creating multilingual practices for all…

This study investigated the impact of language sample length on mean length of utterance (MLU) and aimed to determine the minimum number of utterances required for a reliable MLU. Conversations were collected from Mandarin-speaking, hard-of-hearing and typical-hearing children aged 16-81 months. The MLUs were calculated using sample sizes ranging…

Young learners are known to extend verb regularity further than it actually is. When it happens, this children's overregularization phenomenon can be a result of several reasons: a failed linguistic development due to confusion between rules and memory, a lack of feedback from adults, and problems with cognitive development. The present study…
