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   

Dialogue with a conversational agent promotes children’s story comprehension via enhancing engagement

Dialogic reading, when children are read a storybook and engaged in relevant conversation, is a powerful strategy for fostering language development. With the development of artificial intelligence, conversational agents can engage children in elements of dialogic reading. This study examined whether a conversational agent can improve children's story comprehension and engagement, as compared to an adult reading partner. Using a 2 (dialogic reading or non-dialogic reading) × 2 (agent or human) factorial design, a total of 117 three- to six-year-olds (50% Female, 37% White, 31% Asian, 21% multi-ethnic) were randomly assigned into one of the four conditions. Results revealed that a conversational agent can replicate the benefits of dialogic reading with a human partner by enhancing children's narrative-relevant vocalizations, reducing irrelevant vocalizations, and improving story comprehension.  相似文献   

When friendships surpass parental relationships as predictors of long-term outcomes: Adolescent relationship qualities and adult psychosocial functioning     

Joseph P. Allen  Meghan Costello  Jessica Kansky  Emily L. Loeb 《Child development》2022,93(3):760-777

Perceptions of adolescent–parent and adolescent–peer relationship qualities, and adolescents’ attachment states of mind were examined as predictors of adult social and romantic relationship quality, depressive symptoms, and work performance. Adolescents (86 male, 98 female; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other groups) were followed from age 13 to 24 via observational, self-, parent-, and close friend-reports. Adolescent close friendship quality was a significantly better predictor of adult peer and romantic outcomes, work performance, and depressive symptoms than parental reports of the parent–teen relationship; attachment security was also a strong predictor of numerous outcomes. Results are interpreted as reflecting the difficulty for parents judging parent–teen relationship quality and as reflecting the growing importance of close friendships during this period.  相似文献   

The scope for using international indicators of inclusive education in Kuwait and GCC countries: A preliminary study involving special education teachers     

Zaid N. Al-Shammari  Joseph Mintz 《British Journal of Special Education》2023,50(3):344-354

In both the literature on inclusive education and in international policy development, there has been considerable interest in the use of sets of indicators for the implementation of inclusive education at national and local levels. Drawing on sets of indicators developed in Europe and the Pacific Islands, this study proposes a set of such indicators for Kuwait. These indicators are then presented in a survey of 161 special education teachers working in public elementary mainstream schools across Kuwait. Analysis of the results is used to explore how such indicators could play a role in promoting policy implementation for inclusive education in Kuwait and more widely in Gulf Cooperation Council (GCC) countries.  相似文献

Why would medical publishers not incorporate core bioethical values into their Ethics Guidelines?     

Joseph Watine 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2014,24(1):7-11

It is quite universally acknowledged by bioethicists, at least in the western world, that respect for the patients’ autonomy, non-malevolence, beneficence, and justice (also called equity) are four core ethical values in medicine. The Ethics Guidelines of key journals in laboratory medicine are not explicit about the first three of these values, and even implicitly, they seem to miss values of justice. Health equity being one of the main objectives of public health policy across the world, we suggest that values of equity explicitly become part of the Ethics Guidelines of laboratory medicine journals. Biochemia Medica could show the way to other medical publishers by incorporating into its Ethics Guidelines these very important core bioethical values.  相似文献   

Lower extremity power during the squat jump with various barbell loads     

Daniel Jandacka  Jaroslav Uchytil  Roman Farana  David Zahradnik  Joseph Hamill 《Sports biomechanics / International Society of Biomechanics in Sports》2014,13(1):75-86

The purpose of this study was twofold: (1) to determine the barbell load that maximised the system power as well as the ankle, knee, and hip joint powers during the squat jump, and (2) to compare the system powers computed from two different methods: the centre of mass (COM) method and the barbell method. Seven male throwers were recruited in this study. The system power (COM method) and the ankle, knee, and hip joint powers were determined with the load incrementally set at 0%, 10%, 30%, 50%, 70%, and 90% of one repetition maximum. The largest system power was observed at the load of 30% (p < 0.008) while the largest ankle and knee powers were observed at 70% and 0% (p < 0.05). The barbell method overestimated the system power (p < 0.001) when compared to the COM method. It was concluded that the barbell method could influence load optimisation in squat jump. The optimal barbell load which maximised the system power did not maximise the ankle, knee, or hip power simultaneously.  相似文献   

Musculoskeletal stiffness during hopping and running does not change following downhill backwards walking     

Corey W. Joseph  Elizabeth J. Bradshaw  Justin Kemp  Ross A. Clark 《Sports biomechanics / International Society of Biomechanics in Sports》2014,13(3):241-258

Eccentric contractions that provide spring energy can also cause muscle damage. The aim of this study was to explore leg and vertical stiffness following muscle damage induced by an eccentric exercise protocol. Twenty active males completed 60 minutes of backward-walking on a treadmill at 0.67 m/s and a gradient of ? 8.5° to induce muscle damage. Tests were performed immediately before; immediately post; and 24, 48, and 168 hours post eccentric exercise. Tests included running at 3.35 m/s and hopping at 2.2 Hz using single- and double-legged actions. Leg and vertical stiffness were measured from kinetic and kinematic data, and electromyography (EMG) of five muscles of the preferred limb were recorded during hopping. Increases in pain scores (over 37%) occurred post-exercise and 24 and 48 hours later (p < 0.001). A 7% decrease in maximal voluntary contraction occurred immediately post-exercise (p = 0.019). Changes in knee kinematics during single-legged hopping were observed 168 hours post (p < 0.05). No significant changes were observed in EMG, creatine kinase activity, leg, or vertical stiffness. Results indicate that knee mechanics may be altered to maintain consistent levels of leg and vertical stiffness when eccentric exercise-induced muscle damage is present in the lower legs.  相似文献
