Developmental dyslexia is associated with functional abnormalities within reading areas of the brain. For some children diagnosed
with dyslexia, phonologically based remediation programs appear to rehabilitate brain function in key reading areas (Shaywitz
et al., Biological Psychiatry 55: 101–110, 2004; Simos et al., Neuroscience 58: 1203–1213, 2002). However, a non-trivial number of children diagnosed with dyslexia fail to respond to these interventions (Torgesen, Learning Disabilities Research & Practice 15: 55–64, 2000). A cross-sectional fMRI study investigating post-treatment effects was conducted in an effort to better understand differences
in brain function between treatment responders and non-responders. Educational testing and brain activation measured after
treatment suggested that the reading intervention used in the present study rehabilitated several basic level reading processes
in all participants diagnosed with dyslexia. However, activation in the left inferior parietal lobe differentiated treatment
responders and non-responders in comparison to non-impaired readers. Children with persistent deficits in single word decoding
(treatment non-responders) demonstrated significantly less activation in the left inferior parietal lobe when compared to
non-impaired readers. 相似文献

The present research examined the influence of prior knowledge on children’s free recall, cued recall, recognition memory, and source memory judgments for a series of similar real‐life events. Forty children (5–12 years old) attended 4 thematic birthday parties and were later interviewed about the events that transpired during the parties using the National Institute of Child Health and Human Development protocol. Of the events, half were generic in that they could have occurred at any birthday party, and half were specific to the theme of the party. Older children demonstrated more evidence of using gist‐based information to guide their memory performance than did younger children. However, younger children were able to use global gist to inform their source memory judgments, qualifying past word‐learning research. 相似文献

跳水"压水花"技术运动生物力学研究 总被引：3，自引：0，他引：3
“压水花”是竞技跳水比赛中的关键技术，在训练中已经探索总结出不少“压水花”技术的训练方法，但在理论研究上，还远落后于实践。应用有关力学原理和流固耦合理论，对人、水碰撞过程进行简化和计算机模拟，并对“水花”形成的机理进行进一步的分析探讨，总结出不同形状固体(运动员入水时的手形)、在不同务件下撞击水面时“水花”形成的规律，根据计算机模拟结果和理论研究的成果，对“压水花”技术进行生物力学研究，提出“平掌撞水，压揉结合”的水花控制理论和方法。经对江苏省跳水队部分运动员中进行实验训练，取得了满意的结果。 相似文献

Dyslexia is a specific learning disability that impacts word reading accuracy and/or reading fluency. Over half of the states in the USA have passed legislation intended to promote better identification of individuals with dyslexia. To date, no study has been conducted to investigate the potential impact of state laws on the identification of specific learning disability (SLD), and limited data has been presented on the rate at which students in public school settings are identified with dyslexia. The first aim of the current study was to determine if any detectable changes in the identification rates of SLD have occurred in states implementing dyslexia laws because most states do not report number of students identified as dyslexic but rather those students identified with an SLD. The second aim of the study was to characterize the rate of identifying dyslexia in the two states (Texas and Arkansas) that require public schools to report the number of students identified with dyslexia. The third aim was to characterize the identification rate across first to 12th grades. Current SLD rates range from 3.2 to 8.5% in all 50 states. Analysis of SLD prevalence rates did not vary between states with and without dyslexia laws in place. Moreover, there was no change in the identification of SLD once states had implemented these laws. Rates of dyslexia in Arkansas and Texas were less than 5%. Given the persistent levels indicating lack of reading proficiency, our review of data suggests that overall students with dyslexia are being underidentified. 相似文献

The use of single crystal X-ray diffraction to determine the structure of a chemical compound has been historically classified
as ‘Chemical Crystallography’. The methodologies, the accuracy in experiments coupled with the modern computer gadgets and
advances in technology makes this branch of science an unequivocal provider of accurate and precise measurements of molecular
dimensions. Structure determination by powder diffraction, crystal engineering, charge density analysis and studies on molecules
in excited states are the recent add-ons.

crystallographer and prominent areas of his research are in polymorphism and drug design, charge density analysis andab initio powder diffraction. 相似文献
