Direct linkPeixinho, Jessica; Toseeb, Umar; Mountford, Hayley S.; Bermudez, Isabel; Newbury, Dianne F. – Infant and Child Development, 2022
The negative health effects of cigarette smoking during pregnancy (SDP) on the foetus are well known. Despite previous reports of poor cognitive performance in offspring exposed to SDP, few studies specifically consider language outcomes according to maternal smoking. In this study, we systematically review the literature to assess the…

Dutton, Edward; Van der Linden, Dimitri; Madison, Guy – Journal of Creative Behavior, 2020
Previous research has attempted to understand why countries with relatively favorable conditions and high estimated average IQs (such as Finland and Japan) have a relatively low per capita number of scientific Nobel prizes. In the present study, we examine whether there is a relationship between national schizophrenia and left-handedness…

Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Mosing, Miriam A.; Madison, Guy; Pedersen, Nancy L.; Ullén, Fredrik – Developmental Science, 2016
The idea of far transfer effects in the cognitive sciences has received much attention in recent years. One domain where far transfer effects have frequently been reported is music education, with the prevailing idea that music practice entails an increase in cognitive ability (IQ). While cross-sectional studies consistently find significant…

Chevalere, J.; Postal, V.; Jauregui, J.; Copet, P.; Laurier, V.; Thuilleaux, D. – Journal of Applied Research in Intellectual Disabilities, 2013
Introduction: The aim of the present study was to determine whether individuals with Prader--Willi syndrome (PWS) have impaired global executive functioning and whether this deficit is linked with intellectual disability. Another objective focussed on the variability in performance of intellectual quotient (IQ) and executive functions (EF)…

Pearson, Tanya; Chaisty, Frances; Stenfert Kroese, Biza – International Journal of Developmental Disabilities, 2019
Background: Previous research has largely focused on evaluating the impact of teaching practical parenting skills to parents with intellectual disabilities. Teaching them about the importance and nature of early attachment behaviors has not yet been explored. This study investigates whether knowledge of early attachment behavior of young adults…

Rice, Mabel L.; Zubrick, Stephen R.; Taylor, Catherine L.; Hoffman, Lesa; Gayán, Javier – Journal of Speech, Language, and Hearing Research, 2018
Purpose: This study investigates the heritability of language, speech, and nonverbal cognitive development of twins at 4 and 6 years of age. Possible confounding effects of twinning and zygosity, evident at 2 years, were investigated among other possible predictors of outcomes. Method: The population-based twin sample included 627 twin pairs and 1…

Pitts, C. Holley; Mervis, Carolyn B. – American Journal on Intellectual and Developmental Disabilities, 2016
We describe the performance of 292 4- to 17-year-olds with Williams syndrome (WS) on the Kaufman Brief Intelligence Test-2 (KBIT-2; Kaufman & Kaufman, 2004). Mean IQ Composite, Verbal standard score (SS), and Nonverbal SS were in the borderline range relative to the general population, with variability similar to the general population.…

Fahim, C.; Yoon, U.; Nashaat, N. H.; Khalil, A. K.; El-Belbesy, M.; Mancini-Marie, A.; Evans, A. C.; Meguid, N. – Journal of Intellectual Disability Research, 2012
Background: Genetically Williams syndrome (WS) promises to provide essential insight into the pathophysiology of cortical development because its ~28 deleted genes are crucial for cortical neuronal migration and maturation. Phenotypically, WS is one of the most puzzling childhood neurodevelopmental disorders affecting most intellectual…

Hadd, Alexandria Ree; Rodgers, Joseph Lee – Developmental Psychology, 2017
The quality of the home environment, as a predictor, is related to health, education, and emotion outcomes. However, factors influencing the quality of the home environment, as an outcome, have been understudied--particularly how children construct their own environments. Further, most previous research on family processes and outcomes has…

Emberti Gialloreti, Leonardo; Pardini, Matteo; Benassi, Francesca; Marciano, Sara; Amore, Mario; Mutolo, Maria Giulia; Porfirio, Maria Cristina; Curatolo, Paolo – Journal of Autism and Developmental Disorders, 2014
Recent years have seen an increase in the use of retinal nerve fiber layer (RNFL) evaluation as an easy-to-use, reproducible, proxy-measure of brain structural abnormalities. Here, we evaluated RNFL thickness in a group of subjects with high functioning autism (HFA) or with Asperger Syndrome (AS) to its potential as a tool to study autism…

Whittington, J.; Holland, A.; Webb, T. – Journal of Intellectual Disability Research, 2009
Background: Genetic disorders occasionally provide the means to uncover potential mechanisms linking gene expression and physical or cognitive characteristics or behaviour. Prader-Willi syndrome (PWS) is one such genetic disorder in which differences between the two main genetic subtypes have been documented (e.g. higher verbal IQ in one vs.…

Williams syndrome is characterized by impairments in executive functions (EFs). However, it remains unknown how distinct types of EFs relate to intelligence in this syndrome. The present study analyzed performance on working memory, inhibiting and shifting, and its links to IQ in a sample of 17 individuals with WS, and compared them with a group…

Allen, T. M.; Hersh, J.; Schoch, K.; Curtiss, K.; Hooper, S. R.; Shashi, V. – Journal of Intellectual Disability Research, 2014
Background: Children with 22q11.2 deletion syndrome (22q11DS) are at risk for social-behavioural and neurocognitive sequelae throughout development. The current study examined the impact of family environmental characteristics on social-behavioural and cognitive outcomes in this paediatric population. Method: Guardians of children with 22q11DS…

Duijff, Sasja; Klaassen, Petra; Beemer, Frits; Swanenburg de Veye, Henriette; Vorstman, Jacob; Sinnema, Gerben – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
The purpose of this study was to explore the relationship between intelligence and visual motor integration skills in 5-year-old children with 22q11-deletion syndrome (22q11DS) (N = 65, 43 females, 22 males; mean age 5.6 years (SD 0.2), range 5.23-5.99 years). Sufficient VMI skills seem a prerequisite for IQ testing. Since problems related to…
