Abstract Morphological awareness, the ability to manipulate the smallest units of meaning, is critical for Chinese literacy. This is because Chinese characters typically reflect the morphemic, or morpho-syllabic units of language. Yet, the neurocognitive mechanisms underlying Chinese speakers’ morphological processing remain understudied. Proficient readers (N = 14) completed morphological and phonological judgment tasks in Chinese, in both auditory and visual modalities, during fMRI imaging. Ke...

ABSTRACTThe developmental process of reading acquisition is frequently conceptualized as a self-organizing mental network consisting of lexico-semantic, phonological and orthographical components. The developmental nature of this network varies across languages and is known to impact second-language learners of typologically different languages. Yet, it remains largely unknown whether such cross-linguistic differences interact within young bilingual learners of two typologically different langua...

Can bilingual exposure impact children's neural circuitry for learning to read? To answer this question, we investigated the brain bases of morphological awareness, one of the key spoken language abilities for learning to read in English and Chinese. Bilingual Chinese-English and monolingual English children (N = 22, ages 7–12) completed morphological tasks that best characterize each of their languages: compound morphology in Chinese (e.g. basket + ball = basketball) and derivational morphology...

Deficient self-regulation plays a key role in the etiology of early onset disruptive behavior disorders and signals risk for chronic psychopathology. However, to date, there has been no research comparing preschool children with and without high levels of disruptive behavior using Event Related Potentials (ERPs) associated with specific self-regulation sub-processes. We examined 15 preschool children with high levels of disruptive behavior (35 % female) and 20 peers with low disruptive behavior ...

Abstract The present longitudinal study investigated the predictive power of preschool linguistic skills and early family factors on children's comprehensive literacy skills at the end of primary school in 262 Chinese children. The results indicated that a substantial (20–34%) share of variance of 5th grade (age 11) literacy skills in Chinese could be explained by early family factors (age 3) and linguistic skills (age 3–age 5). Family socioeconomic status and parent-child reading tuition were a...

Parenting strategies involving psychological control are associated with increased adjustment problems in children. However, no research has examined the extent to which culture and psychological control predict children's stress physiology. We examine cultural differences in maternal psychological control and its associations with children's cortisol. Chinese (N = 59) and American (N = 45) mother-child dyads participated in the study. Mothers reported on psychological control. Children's cortis...

Background Lead is a pervasive neurotoxicant that has been associated with poorer cognitive, behavioral, and motor outcomes in children. The effects of lead on sensory function have not been well characterized. The aim of this study was to assess the effects of prenatal lead exposure on infant sensory function, as measured by auditory brainstem response (ABR) and grating visual acuity (VA).

The doublecortin domain-containing 2 (DCDC2) gene, which is located on chromosome 6p22.1, has been widely suggested to be a candidate gene for dyslexia, but its role in typical reading development over time remains to be clarified. In the present study, we explored the role of DCDC2 in contributing to the individual differences in reading development from ages 6 to 11 years by analysing data from 284 unrelated children who were participating in the Chinese Longitudinal Study of Reading Developme...

BACKGROUND: Previous trials of iron supplementation in infancy did not consider maternal iron supplementation. OBJECTIVE: This study assessed effects of iron supplementation in infancy and/or pregnancy on infant iron status illnesses and growth at 9 mo. METHODS: Enrollment occurred from December 2009 to June 2012 in Hebei China. Infants born to women in a pregnancy iron supplementation trial were randomly assigned 1:1 to iron [ approximately 1 mg Fe/(kg . d) as oral iron proteinsuccynilate] or p...
