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, = 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

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 (= 19) and low‐risk comparison mothers (= 30) showed a larger enhancement of ERP responses for emotional faces relative to neutral faces than CPS‐referred control mothers (= 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 electronic learned journal of tomorrow is likely to be substantially different from today's print-on-paper precursor. The emphasis will be on accessibility for the individual user and the objective should be to combine the convenience of the local library collection with the organisation and support services typical of a large general collection. Publishers too will need to adopt access and pricing policies which give priority to the convenience of scholars and which acknowledge value-for-money arguments. Extrapolation from some present day trends may be a useful guide to the future. Parallel publishing itself is likely to be a temporary phenomenon, preceding exclusively electronic scholarly publication in many fields.  相似文献

With its transparent orthography, Standard Indonesian is spoken by over 160 million inhabitants and is the primary language of instruction in education and the government in Indonesia. An assessment battery of reading and reading-related skills was developed as a starting point for the diagnosis of dyslexia in beginner learners. Founded on the International Dyslexia Association’s definition of dyslexia, the test battery comprises nine empirically motivated reading and reading-related tasks assessing word reading, pseudoword reading, arithmetic, rapid automatized naming, phoneme deletion, forward and backward digit span, verbal fluency, orthographic choice (spelling), and writing. The test was validated by computing the relationships between the outcomes on the reading-skills and reading-related measures by means of correlation and factor analyses. External variables, i.e., school grades and teacher ratings of the reading and learning abilities of individual students, were also utilized to provide evidence of its construct validity. Four variables were found to be significantly related with reading-skill measures: phonological awareness, rapid naming, spelling, and digit span. The current study on reading development in Standard Indonesian confirms findings from other languages with transparent orthographies and suggests a test battery including preliminary norm scores for screening and assessment of elementary school children learning to read Standard Indonesian.  相似文献
