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…

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…

Willcutt, Erik G.; Petrill, Stephen A.; Wu, Sarah; Boada, Richard; DeFries, John C.; Olson, Richard K.; Pennington, Bruce F. – Journal of Learning Disabilities, 2013
Reading disability (RD) and math disability (MD) frequently co-occur, but the etiology of this comorbidity is not well understood. Groups with RD only (N = 241), MD only (N = 183), and RD + MD (N = 188) and a control group with neither disorder (N = 411) completed a battery of measures of internalizing and externalizing psychopathology, social and…

Harden, Kathryn P.; Mendle, Jane – Child Development, 2011
Academic achievement and cognitive ability have been shown to predict later age at first sexual intercourse. Using a sample of 536 same-sex twin pairs who were followed longitudinally from adolescence to early adulthood, this study tested whether relations between intelligence, academic achievement, and age at first sex were due to unmeasured…

Chamorro-Premuzic, Tomas; Harlaar, Nicole; Greven, Corina U.; Plomin, Robert – Intelligence, 2010
This paper examines the longitudinal causal relationship between self-perceived abilities (SPA) and academic achievement (Ach) while controlling for cognitive ability (CA). In all, 5957 UK school children were assessed on SPA, Ach and CA at ages 9 and 12. Results indicated that SPA and Ach at age 9 independently affected both SPA and Ach at age…

Spinath, Birgit; Spinath, Frank M.; Harlaar, Nicole; Plomin, Robert – Intelligence, 2006
The present study examined the extent to which motivation contributes to the prediction of school achievement among elementary school children beyond general mental ability ("g"). The sample consisted of "N" = 1678 nine-year-old UK elementary school children who took part in the Twins Early Development Study (TEDS). Teachers…
