The transition to out‐of‐home child care brings a number of challenges for children, including complex peer interactions and extended separations from parents. Children often show a midmorning to afternoon rise in cortisol on child‐care days, compared to the typical diurnal decline seen at home. Changes in cortisol were examined in a wide age range of children (N = 168; 1.2 months to 8 years, M = 3.27 years) during the 10‐week transition to a new child‐care setting. Structural equation modeling using latent change scores showed that children experienced an increase in the cortisol rise at child care across the 10‐week transition. Furthermore, child age moderated the difference between home‐ and child‐care cortisol patterns. Findings are placed in a developmental context, and potential implications and future directions are discussed. 相似文献

Effects of an Attachment‐Based Intervention on Child Protective Services–Referred Mothers' Event‐Related Potentials to Children's Emotions

This study examined the neurobiology of maternal sensitivity to children's emotions among mothers involved with Child Protective Services (CPS) and low‐risk comparison mothers (Mage = 31.6 years). CPS‐referred mothers participated in the Attachment and Biobehavioral Catch‐up (ABC) intervention or a control intervention. Mothers' event‐related potentials (ERPs) were measured while they categorized images of children with crying, laughing, and neutral expressions. CPS‐referred ABC mothers (n = 19) and low‐risk comparison mothers (n = 30) showed a larger enhancement of ERP responses for emotional faces relative to neutral faces than CPS‐referred control mothers (n = 21). Additionally, the magnitude of ERP responses to emotional faces was associated with observed maternal sensitivity. Findings add to the understanding of the neurobiology of deficits in parenting and suggest that these deficits are changeable through a parenting intervention. 相似文献

The purpose of this study was to examine the relationship between motor proficiency and body mass index (B/MI) in preschool children. Thirty-eight children ages 4-6 years had their BMI calculated and were assessed using the Movement Assessment Battery for Children-2 (MABC-2; Henderson, Sugden, & Barnett, 2007). These data were analyzed in two ways. The correlation between BMI and MABC-2 percentile ranks was calculated. Next, the groups were subdivided based on BMI status (high, M = 85.5; medium, M = 49.8; low, M = 10.8), and compared using t tests to determine if differences existed in MABC-2 percentile ranks. No significant relationship existed between MABC-2 and BMI percentile ranks (r = -.237). However significant differences in MABC-2 percentile ranks existed between high and low (p = .042), and high and medium (p = .043) groups. These results suggest that preschool children classified as overweight or obese may have lower motor proficiency than their normal weight and under weight peers. This study indicates there is a direct relationship between motor proficiency and BMI in the preschool population. 相似文献

In this study, students and their teachers participated in a layered approach to reading intervention in kindergarten through third grade that included professional development for teachers in scientifically based reading instruction, ongoing measurement of reading progress, and additional small-group or individual instruction for students whose progress was insufficient to maintain grade-level reading achievement. Reading outcomes were compared with historical control groups of students in the same schools. The findings revealed overall improvements in reading, improved reading for students who began the study in high-risk categories, and decreases in the incidence of reading disability at the end of third grade. Implications for scaling up are discussed. 相似文献

This article sought to examine the differences between transfer and nontransfer students on mental health factors, social involvement, and academic success. It was found that transfer students had significantly higher scores on several mental health factors as compared to nontransfer students. It was also found that transfer students were less involved in athletics and campus organizations, but engaged in more work hours per week. Finally, results indicated that the transfer students were not experiencing significant differences in their academic performance compared to nontransfer students. Future research should examine these differences to better understand the impact of the transition and adjustment of transferring to a new institution. 相似文献

Over the last two decades online technology and digital media have provided space for students to participate and express their voices. This paper further explores how new digital technologies, such as humanoid robots and wearable electronics, can be used to offer additional spaces where students' voices are heard. In these spaces, young students are invited to shape the design of digital tools and artifacts through the inclusion of their unique perspectives. The authors argue that involving youth in the design and use of tools contributes not only to the creation of meaningful learning experiences but also to the future potential of youth as producers of digital learning technologies. 相似文献

The search by naturalists for good characters upon which to base both classifications and determinations of species led some 19th century entomologists to put their faith in insect genitalia as a criteria by which they could differentiate between and classify forms. Karl Jordan was such an entomologist, who turned to these tiny structures as an aid to his work as a museum curator to identify, describe and classify moths and butterflies. In his writings on the subject he also demonstrated how the attempts of systematists to order the diversity of nature had profound implications for the efforts of biologists to explain the origin of that diversity. However, Jordan's plan of how to do systematics well required much more than convincing biologists of the importance of museum work. It also depended on refining the priorities of a natural history community that worked according to diverse means, priorities and methods during a tumultuous century. 相似文献
