The time course of learners’ processing of a complex animation was studied using a dynamic diagram of a piano mechanism. Over successive repetitions of the material, two forms of cueing (standard colour cueing and anti-cueing) were administered either before or during the animated segment of the presentation. An uncued group and two other control conditions were also employed. Development of an internal representation of the movements depicted in the animation was evaluated through participant demonstrations of the mechanism’s operation on a replica piano mechanism. Eye tracking (fixation lengths) indicated that overall, conventional visuospatially-based cueing was largely ineffective for directing attention across the presentations of the animation. Demonstration scores from cued animations were no better than those produced from the uncued version. Cue obedience for standard colour cueing was initially superior to that for anti-cues but fell away after the animation’s first exposure. Contrary to expectations, there was no difference in cue obedience for cueing applied before or during animation of the display. The findings suggest that alternatives to visuospatial cues are needed to help learners process complex animations more effectively. 相似文献

Effects of early child care on children's functioning from 4(1/2) years through the end of 6th grade (M age=12.0 years) were examined in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n=1,364). The results indicated that although parenting was a stronger and more consistent predictor of children's development than early child-care experience, higher quality care predicted higher vocabulary scores and more exposure to center care predicted more teacher-reported externalizing problems. Discussion focuses on mechanisms responsible for these effects, the potential collective consequences of small child-care effects, and the importance of the ongoing follow-up at age 15. 相似文献

Subjects in six experimental groups (n = 16 each) received one-trial passive avoidance (PA) training in which shock was delivered upon movement from a white wooden
floor compartment to a black grid compartment. Then fear was extinguished (30 min) in the black compartment. After either
24 or 168 h, all the groups were treated in a room distinctively different from the training room. At each interval, one group
received a shock in an apparatus similar to the conditioning box, another received a shock in a dissimilar apparatus, and
another was placed in a neutral box. A PA test trial in the training apparatus indicated reinstatement of extinguished fear
in all the groups given a postextinction shock except the 24-h dissimilar group. Control groups revealed that the extinction
treatment was effective and that spontaneous recovery was not evident. The results were explained in terms of classical conditioning,
stimulus generalization, and the broadening (flattening) of stimulus generalization gradients with time. 相似文献

In a special section of the american Annals of the Deaf, Deaf education and the Deaf community in South Africa are discussed. The special section is organized into 7 segments: a historical overview to establish context, the educational context, educators and learners, postgraduate education and employment, perspectives of Deaf children and their parents, sport and the arts, and spiritual lives and mental health. Throughout the entire section, however, the central focus is on the overall foundation (or lack thereof) of education for Deaf learners in South Africa. 相似文献

Fetal neurobehavioral development was modeled longitudinally using data collected at weekly intervals from 24 to 38 weeks gestation in a sample of 112 healthy pregnancies. Predictive associations between 3 measures of fetal neurobehavioral functioning and their developmental trajectories to neurological maturation in the first weeks after birth were examined. Prenatal measures included fetal heart rate (FHR) variability, fetal movement, and coupling between fetal motor activity and heart rate patterning; neonatal outcomes include a standard neurologic examination ( n = 97) and brainstem auditory evoked potential (BAEP; n = 47). Optimality in newborn motor activity and reflexes was predicted by fetal motor activity, FHR variability, and somatic–cardiac coupling predicted BAEP parameters. Maternal pregnancy-specific psychological stress was associated with accelerated neurologic maturation. 相似文献

Exploring the feasibility of a classroom‐based vocabulary intervention for mainstream secondary school students with language disorder 下载免费PDF全文
Vocabulary knowledge has been shown to be a predictor of academic success, posing a challenge for children and young people with language disorder. Language disorder can persist into adolescence and yet there is limited evidence on how to support the vocabulary skills of adolescents with language disorder in a mainstream setting. This article describes an experimental study aimed at investigating the feasibility of a whole‐class approach to increase the understanding and use of curriculum vocabulary in adolescents with language disorder. Ten curriculum words were taught by the science teacher using a phonological‐semantic approach, and 10 matched same‐topic words were taught using routine teaching practice. Progress was made post‐intervention in word knowledge of both low‐frequency experimental and control words, with significantly greater change in knowledge of the experimental words. Most students, and the teacher, viewed the phonological‐semantic word‐learning approach favourably. 相似文献

AbstractIn light of biculturalism's prevalence as a power-sharing agreement between New Zealand Maori and the Crown, any attempts to establish a state-sponsored project of multiculturalism have been treated by Maori with suspicion and controversy. This article presents cosmopolitanism as an appropriate solution to citizenship and cultural diversity in New Zealand that can coexist in harmony with the country's biculturalism that enjoys a constitutional-like status. A state-sponsored policy of liberal multiculturalism comparable to the legal species found in Western democracies, it is argued, would remain mutually exclusive and hostile towards biculturalism. This work concludes with a discussion on the theoretical applications of cosmopolitanism in New Zealand and how it could work empirically, in practice, without attenuating biculturalism. 相似文献
