Why Do Spatial Abilities Predict Mathematical Performance?
Peer reviewed Peer reviewed
Direct linkDirect link
Tosto, Maria Grazia; Hanscombe, Ken B.; Haworth, Claire M. A.; Davis, Oliver S. P.; Petrill, Stephen A.; Dale, Philip S.; Malykh, Sergey; Plomin, Robert; Kovas, Yulia – Developmental Science, 2014
Spatial ability predicts performance in mathematics and eventual expertise in science, technology and engineering. Spatial skills have also been shown to rely on neuronal networks partially shared with mathematics. Understanding the nature of this association can inform educational practices and intervention for mathematical underperformance.…

The Etiology of Variation in Language Skills Changes with Development: A Longitudinal Twin Study of Language from 2 to 12 Years
Peer reviewed Peer reviewed
Direct linkDirect link
Hayiou-Thomas, Marianna E.; Dale, Philip S.; Plomin, Robert – Developmental Science, 2012
The present study is the first long-term longitudinal examination of the etiology of individual differences in language from early childhood through to adolescence. We applied a multivariate latent factor genetic model to longitudinal data from the Twins Early Development Study in order to (a) compare the magnitude of genetic and environmental…

Heritability of Antisocial Behaviour at 9: Do Callous-Unemotional Traits Matter?
Peer reviewed Peer reviewed
Direct linkDirect link
Viding, Essi; Jones, Alice P.; Paul, J. Frick; Moffitt, Terrie E.; Plomin, Robert – Developmental Science, 2008
A previous finding from our group indicated that teacher-rated antisocial behaviour (AB) among 7-year-olds is particularly heritable in the presence of callous-unemotional (CU) traits. Using a sample of 1865 same-sex twin pairs, we employed DeFries-Fulker extremes analysis to investigate whether teacher-rated AB with/without CU traits also shows…

Microarrays
Peer reviewed Peer reviewed
Direct linkDirect link
Plomin, Robert; Schalkwyk, Leonard C. – Developmental Science, 2007
Microarrays are revolutionizing genetics by making it possible to genotype hundreds of thousands of DNA markers and to assess the expression (RNA transcripts) of all of the genes in the genome. Microarrays are slides the size of a postage stamp that contain millions of DNA sequences to which single-stranded DNA or RNA can hybridize. This…

Birthweight-Discordance and Differences in Early Parenting Relate to Monozygotic Twin Differences in Behaviour Problems and Academic Achievement at Age 7
Peer reviewed Peer reviewed
Direct linkDirect link
Asbury, Kathryn; Dunn, Judith F.; Plomin, Robert – Developmental Science, 2006
This longitudinal monozygotic (MZ) twin differences study explored associations between birthweight and early family environment and teacher-rated behaviour problems and academic achievement at age 7. MZ differences in anxiety, hyperactivity, conduct problems, peer problems and academic achievement correlated significantly with MZ differences in…

The Genetic Relationship between Individual Differences in Social and Nonsocial Behaviours Characteristic of Autism
Peer reviewed Peer reviewed
Direct linkDirect link
Ronald, Angelica; Happe, Francesca; Plomin, Robert – Developmental Science, 2005
Two types of behaviours shown in children--those reflecting social impairment and nonsocial obsessive repetitive behaviours--are central to defining and diagnosing autism spectrum disorders (ASDs). Parent and teacher data on social and nonsocial behaviours were obtained from a community sample of greater than 3000 7-year-old twin pairs. Social and…
