In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words. 相似文献

The association of reading disability with perceptuomotor problems has had a chequered history. This study examines the relationship between a new test of ocular dominance and reading and spelling ability in a group of 323 schoolchildren. Similar rates for unfixed ocular dominance were found for poor readers as in comparable studies. The rates of unstable ocular dominance did not differ between those with reading and spelling difficulties and controls. These findings in a ‘blind’ study question the role of this test of eye dominance as a diagnosis of ‘dyslexia’. 相似文献

The present study seeks to identify factors among university students that may be associated with homophobic attitudes and whether homophobia may be reduced by educational interventions, such as knowledge-based curricula found in college sexuality courses. Participants were 128 undergraduate students attending a small, private university in the northwestern region of the United States. At the beginning and end of the fall semester 2004, survey packets consisting of a demographic questionnaire, the Sexual Opinion Survey, the Homophobia Scale, a sexual knowledge survey, and the Bem Sex Role Inventory were administered to students attending a human sexuality class and a comparison group of students enrolled in professional and social science introductory courses. Relative to the comparison group, homophobia levels significantly decreased over the course of the semester among students attending the sexuality class. The effect of attending the class on reducing homophobia was partially mediated by an increase in self-reported knowledge about sexual matters. Taken together, these results suggest that the knowledge-based curriculum of sexuality courses may play an important role in affecting broader attitudes about sexuality among college students, including attitudes about homosexuality. 相似文献

Differential Grading Standards Revisited 总被引:2,自引:0,他引:2
The differential grading standards described by Goldman and Widawski (1976) exist in the same magnitude and in roughly the same order a decade later in a different kind of institution. Major fields that attract as majors students who score higher on SATs employ stricter grading standards. These differential grading standards serve to attenuate the correlation between SAT scores and grades, which is, even in highly selective institutions, substantial. 相似文献

Although the principle of holography was conceived as long ago as 1947, interest was limited until the advent of the laser in 1960 made possible the off-axis holography widely used today. Since then holography has found many applications and become so well known outside the laboratory as to be a recognized art form. Within the last few years considerable progress has also been made in acoustic holography. 相似文献

The purpose of this paper is to compare and contrast characteristics of use and adoption of mobile learning in higher education in developed and developing countries. A comparative case study based on a survey questionnaire was conducted with 189 students (undergraduate and postgraduate) from Makerere University in Uganda and the University of Adelaide in Australia. The Unified Theory of Acceptance and Use of Technology (UTAUT) was employed as the theoretical framework. The results indicated that higher education students in developed and developing countries use a range of technologies for learning, with major differences between Uganda and Australia. The study concludes that mobile learning in higher education in developed and developing country contexts is still at an experimental stage with students using mobile devices in pedagogically limited ways. 相似文献

摘要:今天的美国有1 400万的癌症存活者,其中的很多存活者中都接受了多种治疗,包括手术、放疗、化疗、靶向治疗等。这些治疗能够延长生存时间,但同时也会带来很多急慢性的副作用,危害健康,影响生活质量。体力活动(PA)与癌症生存这一领域发展迅速,主要研究PA对癌症患者的影响。基于该领域的研究进展,提出了以下10大研究问题:1)PA能够降低癌症复发风险、和/或提高存活吗?2)PA能够影响癌症治疗决策、完成率、和/或患者对治疗的反应吗?3)癌症存活者的最佳运动处方是什么?4)静坐少动行为对癌症存活者有何影响?5)癌症存活者最有效的体力活动干预方案是什么?6)哪些癌症会影响病人对PA的反应?7)癌症存活者进行体力活动时需要注意的安全问题有哪些?8)哪些具体的癌症症状可以由PA解决?9)对于癌症晚期患者,体力活动还有何作用?10)如何将体力活动研究结果转化到临床和社区肿瘤实践中来?上述问题的回答至关重要,这不仅关系到体力活动和癌症存活这一研究领域的发展,更重要的是,能够为每年数百万新诊断为癌症的病人、正在接受癌症治疗的病人、治疗结束处于恢复中的病人或是那些正在与晚期癌症抗争的病人带来福音。 相似文献

This project was designed to provide a retrospective analysis of the parent training literature during the last decade. Eighteen journals with behavioral psychology, clinical/counseling psychology, school psychology, and special education emphases were selected for review. Data related to the number of articles published in each journal, year of article publication, referral problem, and contributing institution were collected. Results indicate that behavioral journals published the most empirically based parent training articles (66%), followed by clinical/counseling psychology (26%), special education (6%), and school psychology (3%) journals. Parents with noncompliant, handicapped, or abused/neglected children comprised the majority (58%) of research participants. Suggestions for involving school psychologists in parent training research and broadening the focus of parent training to include preventive, as well as remedial, efforts are presented. 相似文献

This paper examines how research impact is defined, measured, and generated – with a view to understanding how it can be enhanced within heritage conservation. It examines what is meant by ‘impact’ and how it can be promoted within heritage science through effective inter-disciplinary collaboration. Following a general examination of the current discourse concerning research impact, the study examined: (i) active research networks within heritage science; (ii) research planning and evaluation practices within heritage science; and (iii) the experiences of users (i.e. conservators and other heritage professionals) within research collaborations. Terminologies surrounding the notion of impact and the various phases of the research process were reviewed – from the initial identification of a knowledge gap to the eventual application of new findings in practice. Next, the reach and diversity of research collaborations (as identified through publication co-authorship) were studied to characterise the inter-disciplinary nature of heritage science and its connectedness to users. Findings showed substantial growth in international research collaborations over recent years, predominantly involving academic- and research-oriented institutions – although the engagement of heritage institutions has proportionally decreased. In addition, a worldwide survey of institutional planning and evaluation practices revealed a general reliance on processes driven by the interests of researchers – the systematic consideration of stakeholder opinion and evaluation of research outcomes being less common. Finally, a series of semi-structured interviews with senior heritage professionals explored their experience of collaborative research. The results identified key areas where strategic support is needed to promote user participation and enhance impact. These include training for research readiness, engagement, and impact for both researchers and users; better methods for needs and outcome assessment; affordable open access options and greater diversity of knowledge exchange opportunities. Finally, the need for ethical guidelines for responsible research, and greater emphasis on non-academic impact within research rating systems are discussed. 相似文献
