Intellectual performance is highly heritable and robustly predicts lifelong health and success but the earliest manifestations of genetic effects on this asset are not well understood. This study examined whether early executive function (EF) or verbal performance mediate genetic influences on subsequent intellectual performance, in 561 U.S.-based adoptees (57% male) and their birth and adoptive parents (70% and 92% White, 13% and 4% African American, 7% and 2% Latinx, respectively), administered measures in 2003–2017. Genetic influences on children's academic performance at 7 years were mediated by verbal performance at 4.5 years (β = .22, 95% CI [0.08, 0.35], p = .002) and not via EF, indicating that verbal performance is an early manifestation of genetic propensity for intellectual performance. 相似文献

The present study leveraged data from a longitudinal adoption study of 361 families recruited between 2003 and 2010 in the United States. We investigated how psychopathology symptoms in birth parents (BP; Mage = 24.1 years; 50.5–62.9% completed high school) and adoptive parents (AP; Mage = 37.8 years; 80.9% completed college; 94% mother–father couples) influenced children's behavioral inhibition (BI) trajectories. We used latent growth models of observed BI at 18 and 27 months, and 4.5 and 7 years in a sample of adopted children (Female = 42%, White = 57%, Black = 11%, Multi-racial = 21%, Latinx = 9%). BI generally decreased over time, yet there was substantial variability in these trajectories. Neither BP nor AP psychopathology symptoms independently predicted systematic differences in BI trajectories. Instead, we found that AP internalizing symptoms moderated the effects of BP psychopathology on trajectories of BI, indicating a gene by environment interaction. 相似文献

Knowledge about paediatric speech and language difficulties, training for and contact with children with such problems and views on service developments were explored using a written questionnaire, completed by 84 Tanzanian health and education professionals. Additionally, two sets of interviews were carried out, one with a subset of questionnaire respondents and another with a group of 14 health/education planners and administrators. Results showed that whilst only 41 % of respondents had received training about speech and language difficulties, 68% considered themselves to be responsible for assisting children with such problems. Levels of knowledge were significantly higher in the special education group, but were not significantly related to training, exposure to speech and language therapists, or professional responsibility. However, knowledge levels were significantly related to daily contact with children with speech and language difficulties. No evidence of research or planning for children with such difficulties was discovered. Views on service provision favoured educational over health‐based provision. Qualitative information on attitudes and beliefs about speech and language difficulties did not contradict previous data on disabilities. The implications for Tanzania and other similar countries are discussed. Improvements to the questionnaire are discussed. More data are needed in order to facilitate appropriate service development. 相似文献
