Age‐related differences in behavioral and electrophysiological indices of memory were examined in 3‐ to 6‐year‐old children (N = 76). Behaviorally, no differences were observed in children's ability to identify old items; however, 3‐year‐old children were less accurate in correctly rejecting new items, and 3‐ and 4‐year‐old children recalled fewer contextual details compared to 5‐ and 6‐year‐old children. Age‐related differences in electrophysiological measures (800–1,000 ms after stimulus onset) were observed both to items recalled with contextual details, which increased between 3 and 4 years, and items recalled without contextual details, which were greatest in 5‐year‐old children, even after adjusting for global age‐related differences. These findings, interpreted within a dual‐process framework, may suggest changes in both recollection and familiarity processes during early childhood.  相似文献

A growing number of organisations are emerging as partners to districts pursuing systemic improvement. Given the critical role a consulting organisation could play in supporting system reform efforts, how does a district leader looking to establish a consulting partnership determine what characteristics in a consulting organisation may be more likely to yield success? This paper utilises an exploratory sequential mixed methods approach for two purposes: (1) to assess whether the quality domains of consultants most prevalent in the literature are consistent with multiple sources of expert knowledge at the point of practice and (2) to determine which, if any, quality domains of consultants are perceived as more important than others for partnership success. Overall, the findings corroborated that the domains identified through the literature are influential to partnership success. While no specific domain or set of domains emerged as most dominant, interpersonal skills and content expertise are foundational indicators that crosscut the other domains.  相似文献

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR-ASD infants produced fewer vocalizations than HR-Neg infants. From 6 to 24 months, HR-Neg infants demonstrated steeper vocalization growth compared to HR-ASD and LR infants. Finally, among HR infants, vocalizing at 12 months was associated with language, social phenotype, and diagnosis at age 2. Infant vocalizing is an objective behavioral marker that could facilitate earlier detection of ASD.  相似文献

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

It is shown that wrong inferences are drawn from samples because of failure to understand what constitutes a lot and because of failure to verify the existence of a lot in the practically useful sense. Time-tried methods of making valid inferences from samples without increased cost are pointed out.  相似文献
