In human adults, visual dominance emerges in several multisensory tasks. In children, auditory dominance has been reported up to 4 years of age. To establish when sensory dominance changes during development, 41 children (6–7, 9–10, and 11–12 years) were tested on the Colavita task (Experiment 1) and 32 children (6–7, 9–10, and 11–12 years) were tested on the sound‐induced flash illusion (Experiment 2). In both experiments, an auditory dominance emerged in 6‐ to 7‐year‐old children compared to older children. Adult‐like visual dominance started to emerge from 9 to 10 years of age, and consolidated in 11‐ to 12‐year‐old children. These findings show that auditory dominance persists up to 6 years, but switches to visual dominance during the first school years. 相似文献

The goal of the study was to investigate the overlap between developmental language disorder (DLD) and developmental dyslexia, identified through spelling difficulties (SD), in Russian-speaking children. In particular, we studied the role of phoneme awareness (PA), rapid automatized naming (RAN), pseudoword repetition (PWR), morphological (MA), and orthographic awareness (OA) in differentiating between children with DLD who have SD from children with DLD who are average spellers by comparing the two groups to each other, to typically developing children as well as children with SD but without spoken language deficits. One hundred forty-nine children, aged 10.40 to 14.00 years, participated in the study. The results indicated that the SD, DLD, and DLD/SD groups did not differ from each other on PA and RAN Letters and underperformed in comparison to the control groups. However, whereas the children with written language deficits (SD and DLD/SD groups) underperformed on RAN Objects and Digits, PWR, OA, and MA, the children with DLD and no SD performed similarly to the children from the control groups on these measures. In contrast, the two groups with spoken language deficits (DLD and DLD/SD) underperformed on RAN Colors in comparison to the control groups and the group of children with SD only. The results support the notion that those children with DLD who have unimpaired PWR and RAN skills are able to overcome their weaknesses in spoken language and PA and acquire basic literacy on a par with their age peers with typical language. We also argue that our findings support a multifactorial model of DLD. 相似文献

Objective:To compare the accuracy, time to answer, user confidence, and user satisfaction between UpToDate and DynaMed (formerly DynaMed Plus), which are two popular point-of-care information tools.Methods:A crossover study was conducted with medical residents in obstetrics and gynecology and family medicine at the University of Toronto in order to compare the speed and accuracy with which they retrieved answers to clinical questions using UpToDate and DynaMed. Experiments took place between February 2017 and December 2019. Following a short tutorial on how to use each tool and completion of a background survey, participants attempted to find answers to two clinical questions in each tool. Time to answer each question, the chosen answer, confidence score, and satisfaction score were recorded for each clinical question.Results:A total of 57 residents took part in the experiment, including 32 from family medicine and 25 from obstetrics and gynecology. Accuracy in clinical answers was equal between UpToDate (average 1.35 out of 2) and DynaMed (average 1.36 out of 2). However, time to answer was 2.5 minutes faster in UpToDate compared to DynaMed. Participants were also more confident and satisfied with their answers in UpToDate compared to DynaMed.Conclusions:Despite a preference for UpToDate and a higher confidence in responses, the accuracy of clinical answers in UpToDate was equal to those in DynaMed. Previous exposure to UpToDate likely played a major role in participants'' preferences. More research in this area is recommended. 相似文献

ABSTRACT The aims of this study were (a) to describe the kinematics underlying the phenomenon of the knee of the swing leg passing medially in front of the athlete during the single push (SP) phase of the block sprint start, and (b) to determine the relationships between block phase pelvis range of motion (RoM), 1st step width and block phase performance. Three-dimensional kinematic data (250 Hz) were collected from eleven competitive sprinters (100 m PB: 11.17 ± 0.41) performing maximal effort block starts. The joint angles of the rear hip with respect to the pelvis and the pelvis segment angles with respect to the laboratory coordinate system were calculated during the block start phase to the end of the 1st stance. A combination of pelvis list and rotation (not hip adduction) was coupled with the thigh of the swing leg moving medially during the SP phase. A very high positive correlation was found between pelvic list RoM and 1st step width (r = 0.799, p = 0.003). No other significant correlations were found. Attempting to reduce pelvic RoM or changing frontal and transverse plane hip joint angles to minimise medial thigh motion is unlikely to lead to an improvement to performance. 相似文献

ABSTRACTEmployees who fail to balance work and life responsibilities are likely to experience job burnout and, ultimately, withdraw their engagement and voice in the workplace. The current study explored the relationships between employee burnout, work-family balance, and organizational dissent. More importantly, these relationships were tested in an under-researched and culturally unique context, Russia. Data collected from 232 full-time employees in the Perm region were analysed using multiple regression analysis. Analysis revealed that employee burnout is negatively related to articulated dissent and positively related to latent dissent. Furthermore, employees who receive managerial support for prioritizing family issues are less likely to experience job burnout. The influences of national culture and macroeconomic factors on the tested relationships are further discussed 相似文献

This paper examines some international influences on formal education in Africa. It concentrates on the nature of influences since Independence, and points out that links following old colonial routes remain strong, but have been supplemented by American and international agency ones. China and Russia are less influential, although the last decade has witnessed increased activity. Finally, the paper notes, the flow of ideas is predominantly a one-way process. African educators are influenced by dominant ideas in other continents, but the reverse flow of thought is very slight. 相似文献

This article sets a framework for this special issue of the journal by providing an overview of the topic and a commentary on the ways in which the papers in the special issue may be linked to the theme and to each other. The article is built around the identification of diversity and commonality. On the one hand, the Asian region contains countries with widely varying circumstances and socio-political transitions; but on the other hand are a number of common patterns. Among the commonalities are colonial transitions, interrelationships between education and economic changes, and transitions involving international forces and the changing role of the state. 相似文献

Quality in virtual education environments 总被引:1,自引:0,他引:1
Elena Barbera 《British journal of educational technology : journal of the Council for Educational Technology》2004,35(1):13-20
The emergence of the Internet has changed the way we teach and learn. This paper provides a general overview of the state of the quality of virtual education environments. First of all, some problems with the quality criteria applied in this field and the need to develop quality seals are presented. Likewise, the dimensions and subdimensions of an empirical instrument to improve and assess the quality of online education are examined. This tool has already been applied to several educational contexts; though not definitive, it aims to improve not only specific areas, but also the whole educational approach as a system. 相似文献
