Margolis, Amy E.; Davis, Katie S.; Pao, Lisa S.; Lewis, Amy; Yang, Xiao; Tau, Gregory; Zhao, Guihu; Wang, Zhishun; Marsh, Rachel – Developmental Science, 2018
Verbal--spatial discrepancies are common in healthy individuals and in those with neurodevelopmental disorders associated with cognitive control deficits including: Autism Spectrum Disorder, Non-Verbal Learning Disability, Fragile X, 22q11 deletion, and Turner Syndrome. Previous data from healthy individuals suggest that the magnitude of the…

Engelhardt, Laura E.; Church, Jessica A.; Paige Harden, K.; Tucker-Drob, Elliot M. – Developmental Science, 2019
Behavioral and molecular genetic research has established that child cognitive ability and academic performance are substantially heritable, but genetic variation does not account for all of the stratification of cognitive and academic outcomes across families. Which specific contexts and experiences contribute to these "shared…

Gordon, Reyna L.; Shivers, Carolyn M.; Wieland, Elizabeth A.; Kotz, Sonja A.; Yoder, Paul J.; McAuley, J. Devin – Developmental Science, 2015
This study considered a relation between rhythm perception skills and individual differences in phonological awareness and grammar abilities, which are two language skills crucial for academic achievement. Twenty-five typically developing 6-year-old children were given standardized assessments of rhythm perception, phonological awareness,…

Szucs, Dénes; Devine, Amy; Soltesz, Fruzsina; Nobes, Alison; Gabriel, Florence – Developmental Science, 2014
We determined how various cognitive abilities, including several measures of a proposed domain-specific number sense, relate to mathematical competence in nearly 100 9-year-old children with normal reading skill. Results are consistent with an extended number processing network and suggest that important processing nodes of this network are…

Chow, Bonnie Wing-Yin; Ho, Connie Suk-Han; Wong, Simpson Wai-Lap; Waye, Mary M. Y.; Bishop, Dorothy V. M. – Developmental Science, 2013
This study considered how far nonverbal cognitive, language and reading abilities are affected by common genetic influences in a sample of 312 typically developing Chinese twin pairs aged from 3 to 11 years. Children were individually given tasks of Chinese word reading, receptive vocabulary, phonological memory, tone awareness, syllable and rhyme…

Hogan, Alexandra M.; Pit-ten Cate, Ineke M.; Vargha-Khadem, Faraneh; Prengler, Mara; Kirkham, Fenella J. – Developmental Science, 2006
Lowered intelligence relative to controls is evident by mid-childhood in children with sickle cell disease. There is consensus that brain infarct contributes to this deficit, but the subtle lowering of IQ in children with normal MRI scans might be accounted for by chronic systemic complications leading to insufficient oxygen delivery to the brain.…
