Meng, Xiangyun; Sun, Chen; Du, Boqi; Liu, Li; Zhang, Yuxuan; Dong, Qi; Georgiou, George K.; Nan, Yun – Developmental Science, 2022
A long-standing question in developmental science is how the neurodevelopment of the brain influences cognitive functions. Here, we examined the developmental change of resting EEG power and its links to vocabulary acquisition in school-age children. We further explored what mechanisms may mediate the relation between brain rhythm maturation and…

Griffiths, Sarah; Kievit, Rogier A.; Norbury, Courtenay – Developmental Science, 2022
Mutualism is a developmental theory that posits positive reciprocal relationships between distinct cognitive abilities during development. It predicts that abilities such as language and reasoning will influence each other's rates of growth. This may explain why children with Language Disorders also tend to have lower than average non-verbal…

Knauer, Heather A.; Kariger, Patricia; Jakiela, Pamela; Ozier, Owen; Fernald, Lia C. H. – Developmental Science, 2019
In many low- and middle-income countries, young children learn a mother tongue or indigenous language at home before entering the formal education system where they will need to understand and speak a country's official language(s). Thus, assessments of children before school age, conducted in a nation's official language, may not fully reflect a…

Wade, Mark; Browne, Dillon T.; Plamondon, Andre; Daniel, Ella; Jenkins, Jennifer M. – Developmental Science, 2016
The current longitudinal study examined the role of cumulative social risk on children's theory of mind (ToM) and executive functioning (EF) across early development. Further, we also tested a cascade model of development in which children's social cognition at 18 months was hypothesized to predict ToM and EF at age 4.5 through intermediary…

Singh, Leher; Reznick, J. Steven; Xuehua, Liang – Developmental Science, 2012
Infants begin to segment novel words from speech by 7.5 months, demonstrating an ability to track, encode and retrieve words in the context of larger units. Although it is presumed that word recognition at this stage is a prerequisite to constructing a vocabulary, the continuity between these stages of development has not yet been empirically…

Marchman, Virginia A.; Fernald, Anne – Developmental Science, 2008
The nature of predictive relations between early language and later cognitive function is a fundamental question in research on human cognition. In a longitudinal study assessing speed of language processing in infancy, Fernald, Perfors and Marchman (2006 ) found that reaction time at 25 months was strongly related to lexical and grammatical…
