Language development and literacy skills in late-talking toddlers with and without familial risk for dyslexia 总被引:2,自引:0,他引:2
The relationship between late-talkers' language development and reading and spelling outcomes was examined in children with and without familial risk for dyslexia. The late-talking subgroups were defined using parent- and test-based assessments of receptive and expressive vocabulary and grammar at 2 and 2.5 years as intake criteria. The language skills of late talkers and the remainders of these two groups were assessed at 3.5, 5, and 5.5 years. Reading/spelling outcomes were compared at the end of the second grade. Late-talking toddlers of the at-risk group who had both poor receptive and expressive skills performed less well than all other groups on language measurements at 5.5 years. In contrast, the control group's late talkers with an expressive delay reached the language level of their age-mates already by 3.5 years, and maintained their age-appropriate position two years later. The most significant differences in the reading skills were found between the at-risk children with receptive and expressive delay and the remainder of the controls. Age-appropriate early language skills did not, however, ensure norm-level fluent reading in the at-risk group. The remainder of the at-risk group performed at a significantly lower level than did the remainder of the controls, both on the oral reading and spelling tasks. 相似文献

这篇论文是一个关于加拿大和日本中学生(194人)怎样理解和想象“世界公民身份”的实验性研究的结果。对于研究结果的分析表明,尽管两国学生的看法有很多相似之处。但他们在形成全球观念的能力上存在重大差异——尤其是在多大程度上对未来持乐观态度和把自己看作解决全球问题的积极参与者方面。基于此,目前正在进行旨在强调国际化和跨文化对话的课程改革的日、加两国教育当局必须注意这些与培养学生世界公民观念密切相关的可能性与矛盾性。 相似文献

"大陆花嫁①"政策是"满洲②移民"政策的重要辅助工具。日本在"九一八事变"后出于政治与军事目的,再次提出了向"满洲移民"的计划,并且从1932年开始实施。在实施的过程中,由于"屯垦病"的出现使其濒于破产,为了解决该问题,东宫铁男提出了"大陆花嫁"计划,号召女性到"满洲"去。于此同时,由于受到世界经济危机的影响,日本出现了"昭和恐慌",经济疲敝,为了摆脱贫困状态,受到日本(政府欺骗性)宣传的影响,部分日本农村女性渴望到达"满洲",开拓自己的新天地;此外,由于媒体的影响,日本女性对于自己的过劳的生活状态不满,开始渴望获得自由,获得美满的家庭生活,因而选择奔赴"满洲"。随着日本的战败,这些来到中国东北的"大陆花嫁"最终沦落为日本军国主义的牺牲品。 相似文献

We measured event-related potentials (ERPs) to synthetic consonant-vowel syllables (/ba/, /da/, /ga/) from 26 newborns with familial risk for dyslexia and 23 control infants participating in the Jyv?skyl? Longitudinal Study of Dyslexia. The syllables were presented with equal probability and with interstimulus intervals ranging from 3,010 to 7,285 ms. Analyses of averaged ERPs from the latencies identified on the basis of principal component analysis (PCA) revealed significant group differences in stop-consonant processing in several latency ranges. At the latencies of 50-170 ms and 540-630 ms, the responses to /ga/ were larger and more positive than those to /ba/ and /da/ in the right hemisphere in the at-risk group. Between 740 and 940 ms, the responses to /ba/ and /da/ differed between anterior and posterior electrode sites in the control group. These results indicate that the cortical electric activation evoked by speech elements differs between children with and without risk for dyslexia even immediately after birth. Group-related effects at early and late latency ranges of ERPs suggest differences both in the early sound processing based on activation of afferent elements and in later phases of syllable encoding. 相似文献

Children and adolescents (N = 1,057), divided by gender, at fourth, seventh, and tenth grades, from two mid-sized cities in the United States and in Japan, were surveyed regarding their evaluations of peer group exclusion of atypical peers. Six reasons for atypicality were being aggressive, having an unconventional appearance, acting like a clown, demonstrating cross-gender behavior, being a slow runner, and having a sad personality. Analyses revealed significant effects for age, gender, country membership, and the context of exclusion. With age, children demonstrated context sensitivity, and believed that the excluded child should not change him- or herself to be accepted by the group. Across contexts, girls were less willing to exclude than were boys, and were more tolerant of differences. The context of exclusion had an effect on all forms of judgments about exclusion, and there were very few overall effects for culture. Most children disagreed with the decision to exclude, believed that they were different from the atypical child, and believed that the excluded child should change him- or herself to be accepted by the group. The results support a theory of developmental social cognition in which multiple sources of influence have a significant effect on social decision making involving the exclusion of others. 相似文献

提高大学生批判性思维能力——对此类研究的评论 总被引:1,自引:0,他引:1
许多年来,人们已经认识到教育——特别是大学水平的教育的一个基本目的是增强学生们的批判性地思维、推理能力及决断时有效使用判断力的能力.两个最近所作的全国性报告重新唤起了人们对大学生批判性思维能力的兴趣并进而强调本科生教育的一个基本组成部分是发展这些能力.美国国家教育协会1984年作了题为《明确美国高等教育潜力》的报告,引导本科生教育的提高,并指出课程设置“保证了分析、解决问题、交际及综合等能力的培养”报告指出,高校教育应该使学生能够适应变化着的世界,这需要“批判性思维能力以及综合大量信息的能力.” 相似文献

The phyAm gene encoding acid phytase and optimized neutral phytase phyCs gene were inserted into expression vector pPIC9K in correct orientation and transformed into Pichiapastoris in order to expand the pH profile of phytase and decrease the cost of production. The fusion phytase phyAm-phyCs gene was successfully overexpressed in P. pastoris as an active and ex-tracellular phytase. The yield of total extracellular fusion phytase activity is (25.4±0.53) U/ml at the flask scale and (159.1±2.92) U/ml for high cell-density fermentation, respectively. Purified fusion phytase exhibits an optimal temperature at 55 ℃ and an optimal pH at 5.5~6.0 and its relative activity remains at a relatively high level of above 70% in the range of pH 2.0 to 7.0. About 51% to 63% of its original activity remains after incubation at 75 ℃ to 95 ℃ for 10 min. Due to heavy glycosylation, the expressed fusion phytase shows a broad and diffuse band in SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis). After deglycosylation by endoglycosidase H (EndoHf), the enzyme has an apparent molecular size of 95 kDa. The characterization of the fusion phytase was compared with those of phyCs and phyAm. 相似文献

The aim of this study was to determine if adults spontaneously exploit the laws of physics to achieve better accuracy when throwing at various distances. Eight adults performed 25 underarm throws at five horizontal circular targets located 4, 5, 6, 7 and 8 m away with a constant 5% relative accuracy requirement. Angle and speed of the ball at release were found to increase with throwing distance, while the coordinates of the release point did not change significantly. These results support the idea that people minimize the variability in impact distance by adapting both the angle and the speed at ball release following a mechanical optimum predicted by the laws of physics. Moreover, variability in distance was found to be less than expected because of independent variations in the angle and speed at ball release. Hence, the control of precision throwing seems to imply compensatory variability, as frequently reported in the control of skilled actions. 相似文献
