Robustness, risk and responsivity in early language acquisition

Language is a robust developmental phenomenon, characterised by rapid and prodigious growth.

Genome-Wide Analyses of Vocabulary Size in Infancy and Toddlerhood: Associations With Attention-Deficit/Hyperactivity Disorder, Literacy, and Cognition-Related Traits

The number of words children produce (expressive vocabulary) and understand (receptive vocabulary) changes rapidly during early development, partially due to genetic factors. Here, we performed a meta-genome-wide association study of vocabulary acquisition and investigated polygenic overlap with literacy, cognition, developmental phenotypes, and neurodevelopmental conditions, including attention-deficit/hyperactivity disorder. 

Language and reading impairments are associated with increased prevalence of non-right-handedness

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies.

Discovery of 42 genome-wide significant loci associated with dyslexia

Reading and writing are crucial life skills but roughly one in ten children are affected by dyslexia, which can persist into adulthood. Family studies of dyslexia suggest heritability up to 70%, yet few convincing genetic markers have been found.

Aspects of speech-language abilities are influenced by MECP2 mutation type in girls with Rett syndrome

This study investigates relationships between methyl-CpG-binding protein 2 gene (MECP2) mutation type and speech-language abilities in girls with Rett syndrome.

Prenatal, perinatal, and neonatal risk factors for specific language impairment: A prospective pregnancy cohort study

Although genetic factors are known to play a causal role in specific language impairment (SLI), environmental factors may also be important. This study...

The SLI construct is a critical link to the past and a bridge to the future

Commentary on Bishop, D. V. M., Ten questions about terminology for children with unexplained language problems.

Early development of emerging and English-proficient bilingual children at school entry in an Australian population cohort

Children who enter school with limited proficiency in the language of instruction face a range of challenges in negotiating this new context, yet limited...

Factors for Children's Receptive Vocabulary Development from Four to Eight Years in the Longitudinal Study of Australian Children

Variation in receptive vocabulary ability is associated with variation in children's school achievement, and low receptive vocabulary ability is a risk...

The association between perinatal testosterone concentration and early vocabulary development

Prenatal exposure to testosterone is known to affect fetal brain maturation and later neurocognitive function.
