Objective: We leveraged common genetic variation underlying ADHD, educational attainment (EA) and cognition (COG) to understand the nature of the Behavior Rating Inventory for Executive Functions (BRIEF) and its relationship to academic functioning. Method: Participants were 991 youth, ages 7 to 17, consecutively referred for neuropsychiatric…

Womack, Sean R.; Beam, Christopher R.; Davis, Deborah Winders; Finkel, Deborah; Turkheimer, Eric – Developmental Psychology, 2022
Twins regularly score nearly a standard deviation below the population mean on standardized measures of cognitive development in infancy but recover to the population mean by early childhood, making rapid gains through the toddler years. To date, only polynomial growth models have been fit to model cognitive recovery across childhood, limiting the…

Giangrande, Evan J.; Beam, Christopher R.; Finkel, Deborah; Davis, Deborah W.; Turkheimer, Eric – Child Development, 2022
This study investigated the systematic rise in cognitive ability scores over generations, known as the "Flynn Effect," across middle childhood and early adolescence (7-15 years; 291 monozygotic pairs, 298 dizygotic pairs; 89% White). Leveraging the unique structure of the Louisville Twin Study (longitudinal data collected continuously…

Jente Verbesselt; Jeroen Breckpot; Inge Zink; Ann Swillen – Journal of Speech, Language, and Hearing Research, 2024
Purpose: Individuals with proximal 16p11.2 copy number variants (CNVs), either deletions (16p11.2DS) or duplications (16p11.2Dup), are predisposed to neurodevelopmental difficulties and disorders, such as language disorders, intellectual disability, and autism spectrum disorder. The purpose of the current study was to characterize language…

Zajda, Joseph – Curriculum and Teaching, 2019
This article analyses research of theories and models of intelligence. It examines current developments in intelligence research, covering the formation of more complex and diverse intelligence theories. First, the article examines some of the widely used aptitude/intelligence tests include, such Stanford-Binet Intelligence Quotient, Wechsler…

Given the importance of writing for academic achievement, this study aimed to understand how early oral language contributes to later writing skills. The first objective was to determine if preschool language skills were associated with high school writing, and if so, whether they contributed directly or indirectly through school age language. The…

Andres, Erin M.; Earnest, Kathleen Kelsey; Smith, Shelley D.; Rice, Mabel L.; Raza, Muhammad Hashim – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Specific language impairment (SLI) is characterized by a delay in language acquisition despite a lack of other developmental delays or hearing loss. Genetics of SLI is poorly understood. The purpose of this study is to identify SLI genetic loci through family-based linkage mapping. Method: We performed genome-wide parametric linkage…

Wertz, Jasmin; Belsky, Jay; Moffitt, Terrie E.; Belsky, Daniel W.; Harrington, HonaLee; Avinun, Reut; Poulton, Richie; Ramrakha, Sandhya; Caspi, Avshalom – Developmental Psychology, 2019
Twin studies have documented that parenting behavior is partly heritable, but it is unclear how parents' genetics shape their caregiving. Using tools of molecular genetics, the present study investigated this process by testing hypotheses about associations between a genome-wide polygenic score for educational attainment and parental caregiving in…

Mimeau, Catherine; Dionne, Ginette; Feng, Bei; Brendgen, Mara; Vitaro, Frank; Tremblay, Richard E.; Boivin, Michel – Language Learning and Development, 2018
This twin study examined the genetic and environmental etiology of vocabulary, syntax, and their association in first graders. French-speaking same-sex twins (n = 555) completed two vocabulary tests, and two scores of syntax were calculated from their spontaneous speech at 7 years of age. Multivariate latent factor genetic analyses showed that…

Uzun Cicek, Ayla; Sari, Seda Aybuke; Mercan Isik, Cansu – Journal of Mental Health Research in Intellectual Disabilities, 2020
Introduction: Intellectual disability (ID) is characterized by limitations in cognitive and adaptive functioning. The aim of this study is to examine sociodemographic characteristics, perinatal and childhood risk factors, and prevalence of psychiatric and biomedical comorbidities in children with ID. Methods: 260 patients with ID were included in…

C.; Zander, E.; Charman, T. – Journal of Autism and Developmental Disorders, 2018
Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Tosto, Maria G.; Hayiou-Thomas, Marianna E.; Harlaar, Nicole; Prom-Wormley, Elizabeth; Dale, Philip S.; Plomin, Robert – Developmental Psychology, 2017
This study examines the genetic and environmental etiology underlying the development of oral language and reading skills, and the relationship between them, over a long period of developmental time spanning middle childhood and adolescence. It focuses particularly on the differential relationship between language and two different aspects of…

Purpose: Researchers have previously shown that individual differences in measures of receptive language ability at age 12 are highly heritable. In the current study, the authors attempted to identify some of the genes responsible for the heritability of receptive language ability using a "genome-wide association" approach. Method: The…

Method: Phenotypic and quantitative genetic analyses using longitudinal data from the Twins Early Development Study (Oliver & Plomin, 2007) were conducted. A total of 2,923…

Brett, Zoe H.; Sheridan, Margaret; Humphreys, Kate; Smyke, Anna; Gleason, Mary Margaret; Fox, Nathan; Zeanah, Charles; Nelson, Charles; Drury, Stacy – International Journal of Behavioral Development, 2015
An individual's neurodevelopmental and cognitive sequelae to negative early experiences may, in part, be explained by genetic susceptibility. We examined whether extreme differences in the early caregiving environment, defined as exposure to severe psychosocial deprivation associated with institutional care compared to normative rearing,…
