Cawley, John; Han, Euna; Kim, Jiyoon; Norton, Edward C. – National Bureau of Economic Research, 2020
The educational attainment of siblings is highly correlated. We test for a specific type of peer effect between siblings in educational attainment: genetic nurture. Specifically, we test whether a person's educational attainment is correlated with their sibling's polygenic score (PGS) for educational attainment, controlling for their own PGS for…

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…

Donnellan, M. Brent; Martin, Monica J.; Senia, Jennifer M. – Developmental Psychology, 2021
Genetic and environmental factors account for variability in a range of developmental outcomes, including socioeconomic status (SES). The challenge is to find ways to incorporate genetic information based on studies using biologically related family members (i.e., studies not involving twins). To address this issue, we computed polygenic scores…

Gustavson, Kristin; Torvik, Fartein A.; Eilertsen, Espen M.; Ask, Helga; McAdams, Tom A.; Hannigan, Laurie J.; Reichborn-Kjennerud, Ted; Ystrom, Eivind; Gjerde, Line C. – Developmental Psychology, 2021
Children with attention deficit hyperactivity disorder (ADHD) often experience co-occurring emotional problems. ADHD with this comorbidity is associated with poorer outcomes than ADHD without comorbidity. Better understanding of the etiology of comorbidity could improve prevention of negative outcomes for children with ADHD. The sample consisted…

Helland, Siri Saugestad; Røysamb, Espen; Brandlistuen, Ragnhild Eek; Melby-Lervåg, Monica; Gustavson, Kristin – Journal of Learning Disabilities, 2020
Studies have identified concurrent, longitudinal, and bidirectional associations between language difficulties and internalizing problems. This is commonly explained by social exclusion or withdrawal from peers, but underlying mechanisms are not well understood. This study uses sibling data to investigate if the comorbidity between language…

Kim, Jinho – School Psychology, 2021
Students' sense of social relatedness at school predicts health and well-being throughout life. However, little is known about whether observed associations reflect unobserved family background factors and whether these associations differ between student-student and student-teacher relationships. Using data from the National Longitudinal Study of…

Rankin, James A.; Tomeny, Theodore S. – Journal of Autism and Developmental Disorders, 2019
Research on siblings of youth with autism spectrum disorder (ASD) suggests that some phenotypic presentation, known as the broader autism phenotype (BAP), is common among siblings without an ASD diagnosis (e.g., Ruzich et al. in Autism Res 9(6):658-665, 2016). Whereas the symptoms that underlie both ASD and the BAP share commonality, the structure…

Wan, Ming Wai; Green, Jonathan; Scott, Jordan – Autism: The International Journal of Research and Practice, 2019
Social communicative precursors to autism spectrum disorder may influence how infants who are later diagnosed with autism spectrum disorder interact with their social partners and the responses they receive, thus bidirectionally influencing early social experience. This systematic review aimed to identify a developmental timeline for parent-infant…

Raza, Sarah; Sacrey, Lori-Ann R.; Zwaigenbaum, Lonnie; Bryson, Susan; Brian, Jessica; Smith, Isabel M.; Roberts, Wendy; Szatmari, Peter; Vaillancourt, Tracy; Roncadin, Caroline; Garon, Nancy – Journal of Autism and Developmental Disorders, 2020
Social-emotional behavior in autism spectrum disorder (ASD) was examined among high-risk (HR; siblings of children diagnosed with ASD) and low-risk (LR; no family history of ASD) toddlers. Caregivers completed the Infant-Toddler Social Emotional Assessment (ITSEA) at 18 months, and blind diagnostic assessment for ASD was conducted at 36 months.…

Chad; Hazlett, Heather C.; Emerson, Robert W.; Botteron, Kelly; Pandey, Juhi; Schultz, Robert T.; Dager, Stephen R.; Zwaigenbaum, Lonnie; Estes, Annette M.; Piven, Joseph – Child Development, 2018
Children's early language environments are related to later development. Little is known about this association in siblings of children with autism spectrum disorder (ASD), who often experience language delays or have ASD. Fifty-nine 9-month-old infants at high or low familial risk for ASD contributed full-day in-home language recordings.…

Figlio, David N.; Freese, Jeremy; Karbownik, Krzysztof; Roth, Jeffrey – National Center for Analysis of Longitudinal Data in Education Research (CALDER), 2018
Accurate understanding of environmental moderation of genetic influences is vital to advancing the science of cognitive development as well as for designing interventions. One widely-reported idea is increasing genetic influence on cognition for children raised in higher socioeconomic status families, including recent proposals that the pattern is…

Campbell, Susan B.; Northrup, Jessie B.; Tavares, Amy B. – Autism: The International Journal of Research and Practice, 2019
Children with autism spectrum disorder often demonstrate difficulties with self-regulation, although studies of this construct in young children with autism spectrum disorder are limited. In this study, developmental changes were examined using a measure of self-regulation appropriate for young children, resistance to temptation. At 22, 28, and 34…

Kornilov, Sergey A.; Grigorenko, Elena L. – Journal of Learning Disabilities, 2018
In this study, we performed a latent profile analysis of reading and related skills in a large (n = 733) sibpair sample of Russian readers at risk for reading difficulties. The analysis suggested the presence of seven latent profiles, of which two were characterized by relatively high performance on measures of spelling and reading comprehension…

This study examined sensory responsiveness in unaffected siblings of children with autism spectrum disorder (ASD) and associations between sensory responsiveness and social severity. Sensory Profile Caregiver Questionnaires and Social Responsiveness Scales were completed by parents of 185 children between age 4 and 10.95 years. Significant…

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…
