This study investigated the effect of semantic information on artificial grammar learning (AGL). Recursive grammars of different complexity levels (regular language, mirror language, copy language) were investigated in a series of AGL experiments. In the with-semantics condition, participants acquired semantic information prior to the AGL…

The current study establishes the reliability of the Holy Qur'an as one of the earliest treatise on language acquisition by humans. This is not to say that it is a scientific treatise: Rather what we know as modern 'knowledge' finds mention in a book much older. This applies to many aspects of human life, whether they spring from scientific…

Ambridge argues that the existence of exemplar models for individual phenomena (words, inflection rules, etc.) suggests the feasibility of a unified, exemplars-everywhere model that eschews abstraction. The argument would be strengthened by a description of such a model. However, none is provided. I show that any attempt to do so would immediately…

Daylong at-home audio recordings from 10 Tseltal Mayan children (0;2-3;0; Southern Mexico) were analyzed for how often children engaged in verbal interaction with others and whether their speech environment changed with age, time of day, household size, and number of speakers present. Children were infrequently directly spoken to, with most…

While we know that interventions targeting oral language can be effective, little is known about what drives these effects. In this study, we examine whether gains in transfer measures are mediated through the specific words that are trained in a language intervention. Based on a large-scale randomized controlled trial of language intervention in…

Background: Children with developmental language disorder (DLD) are at higher risk of poorer mental health compared with children without DLD. There are, however, considerable individual differences that need to be interpreted, including the identification of protective factors. Aims: Pathways from the early language and communication environment…

Over the past decade, the LLAMA language aptitude test battery has come to play an increasingly important role as an instrument in research on individual differences in language development. However, a potentially serious problem that has been pointed out by several scholars is that the LLAMA has not yet been carefully validated. We addressed this…

Aggression observed in early childhood is considered to be an important problem. Multiple factors may play a decisive role in children's aggressive behaviors. The aim of this study was to examine whether the receptive and expressive language skills of preschool children (39-75 months-old) had predictive role on the levels of physical and…

Massive Open Online Courses (MOOC) made the promise of offering unrestrictive and unselective educational opportunities to learners worldwide. However, the specific learning environment of the MOOC requires high autonomy and flexibility in learning. MOOC learners are extremely diverse in terms of their age, qualifications, background and in the…

Children who are deaf and hard of hearing (DHH) and born to hearing parents have delays in their social-cognitive development and in particular in their theory of mind (ToM). These delays are often attributed to the difficulties they encounter in acquiring age-appropriate linguistic and communicative skills. The present study asks whether this…

We explored whether supported (SJE) or coordinated joint engagement (CJE) between mothers recruited from the community and their 24-month-old children who were slow-to-talk at 18 months old were associated with child language scores at ages 24, 36, and 48 months (n = 197). We further explored whether SJE or CJE modifed the concurrent positive…

Children's speech development begins in infancy. The pattern of this development has been explored in studies over a number of years using a range of research methodology and approaches to investigation. A systematic review of the existing literature was carried out to determine the collective contribution of this literature to our understanding…

In bilingual language environments, infants and toddlers listen to two separate languages during the same key years that monolingual children listen to just one and bilinguals rarely learn each of their two languages at the same rate. Learning to understand language requires them to cope with challenges not found in monolingual input, notably the…

Purpose: The aim of this study was to investigate children's acquisition of Vietnamese speech sounds. Method: Participants were 195 children aged 2;2-5;11 (years;months) living in Northern Viet Nam who spoke Vietnamese as their 1st language. Single-word samples were collected using the Vietnamese Speech Assessment (Ph?m, Le, & McLeod, 2016) to…

Over two decades ago, the "30-million-word" gap rose to prominence after work by Hart & Risley (1995) suggested that children from families with low socioeconomic status (SES) heard fewer words than their peers from families with higher SES during their first 4 years of life. Recent research challenges the magnitude and even…
