We investigated the effects of an intermittent reinforcement procedure on maintenance of verbal/nonverbal correspondence with nutritious snack choices in a day-care setting. Nutritious snack choices were first established using correspondence training procedures in a multiple baseline across three children. Withdrawal of the procedures with one subject led to loss of appropriate responding, suggesting the need for a maintenance strategy. The intermittent reinforcement procedure was implemented in a multiple baseline across subjects. Nutritious snack choices were observed consistently during the intermittent reinforcement condition and the subsequent extinction condition. 相似文献

In contrast to the motive literature, motivational intensity theory predicts that the implicit achievement motive (nAch) should only exert an indirect impact on effort by limiting the impact of task difficulty. To contrast these two views, sixty-eight participants with a low or high nAch performed an easy or difficult arithmetic task. Effort was assessed using cardiac pre-ejection period (PEP). Supporting motivational intensity theory’s view, PEP response was low in both easy-task conditions but stronger in the high-nAch group than in the low-nAch group in the difficult task. These findings suggest that nAch exerts an indirect effect on effort investment by setting the maximally justified effort instead of directly determining the amount of effort that is invested to satisfy the motive. 相似文献

幼儿对文字的关注是内化文字形式和功能(文字意识)的基本途径,如何有效提高年幼儿童对文字的关注是一个具有重要实践意义的课题。本研究以54名2~3岁幼儿为研究对象,记录和分析幼儿在自读、伴读和指读三种方式下阅读图画书的眼动行为。结果发现:1)自读和伴读方式下,2~3岁幼儿对文字和图画的关注具有相同的眼动模式,并且对文字的关注程度均较低;2)指读可显著提高幼儿对文字的关注频率,同时对文字注视时间、次数以及关注速度均表现出一定的促进作用;3)对图画的整体分析显示,指读与伴读/自读方式之间的眼动模式差异不显著;而进一步对图画的局部分析表明:指读不影响幼儿图画关注的全面性和有效性。综上所述,指读在一定程度上能够促进年幼儿童对文字的关注,同时动态手势也不抢占儿童阅读图画的注意资源。 相似文献

Historically, the role of school psychologists in early childhood settings has been limited to the identification and evaluation of children who may be in need of special education services under Part B of the Individuals with Disabilities Education Act. It has been suggested that the role should reflect a more proactive model; specifically, it should continue to expand to include involvement in school readiness and early intervention for all students. The purpose of this study was to examine the present role of school psychologists in early childhood settings and investigate the graduate-level training provided to school psychology graduate students. Results of the survey found that a significant percentage of school psychologist practitioners continue to spend a substantial portion of their professional time completing special education evaluations. Furthermore, respondents reported minimal to moderate graduate training in the area of early childhood populations. Implications for school psychology practitioners and school psychology graduate training programs are discussed. 相似文献

This study aimed to assess sexual risk behaviour and its social correlates in HIV-infected women living in rural South Africa at six and twelve months post-partum. Participants were 699 HIV-positive women recruited prenatally by systematic sampling from twelve community health centres in Mpumalanga province, South Africa (mean age = 28.4 years, SD = 5.7; married =41.1%; serodiscordant or unknown partner status = 74.9%). They self-reported on their sexual activity six to twelve months after delivery; including use of condoms and partner involvement. Generalised linear mixed models were utilised to estimate unsafe sex outcomes from a prevention of mother to child transmission (PMTCT) intervention, socio-demographic factors, disclosure, and male involvement. About 20% of sexually active women in the past week had used condoms inconsistently at six and twelve months after delivery. Moreover, 16% and 18% of the women had not used a condom at last sex and 11% and 13% had unprotected sex with HIV-uninfected or unknown-status partners following delivery at six and twelve months, respectively. Higher inconsistent condom use was likely with lower male involvement. Promotion of condom use post-partum, as well as male involvement in sexual decisions, are important for safer sex post-partum by seropositive women. 相似文献

在中国历史上,关于国家安全问题的战略性思考起源于先秦时期,许多重要的指导思想和原则,如以民为本、和而不同、慎战、亲仁善邻等思想已在那时得到了明晰。这些宝贵的思想具有久远而深厚的文化基础。他们不仅为历朝历代安内攘外,维系中国作为世界上唯一不曾中断几千年文明进程的国家发挥了重要的历史作用。而且对于我们今天研究安全问题、制定国家安全战略提供了可资借鉴的价值。 相似文献

ABSTRACTResearch in action memory for adults has shown that enacted encoding is not only retrieved more frequently but is also faster in comparison to verbal encoding. The aim of this study was to investigate retrieval processes in terms of recall period and recall difficulty for different encoding conditions in school-aged children (8-, 10-, 12-, 14-years old). The participants studied verbal tasks, subject-performed tasks and experimenter-performed tasks, and received immediate and final free-recall tests. The results revealed that older children not only outperformed younger children in terms of accuracy but also outpaced them in all recall periods. Moreover, recalls of subject-performed tasks and experimenter-performed tasks were better and faster compared with verbal encoding on both types of recall test, by increasing throughout the recall periods. These results are discussed in terms of memory strategies and information processing methods. Pedagogic implications for the use of action memory in children's learning are also considered. 相似文献

Genetic and Environmental Influences on the Development and Stability of Executive Functions in Children of Preschool Age: A Longitudinal Study of Japanese Twins 下载免费PDF全文
Executive functions (EF) are an important predictor of later adaptive development. A number of environmental influences, such as parenting, have been suggested as important promoters of EF development. However, behavioural genetic research has demonstrated that many environmental influences could be affected by genetic influences. Therefore, it is important to consider genetic variations when investigating environmental influences on EF development in children. To date, few studies have used genetically informative designs to assess the etiology of EF development during the preschool years, a period of rapid development. As a result, it remains unclear how and to what extent the environmental influences that are not confounded by genetic influences affect EF development during this developmental period. The present study explored EF development during the preschool years using a longitudinal and genetically informative design and a non‐Western population. Japanese twins were visited at their homes and individually tested on EF measures at 24, 36, and 48 months of age. Phenotypic correlations and confirmatory factor analyses suggested that EF are less cohesive at 24 months of age and emerge as a common single factor at 36 and 48 months. Additionally, longitudinal and multivariate behavioural genetic analyses indicated that the EF developmental change during this period is promoted by both shared and nonshared environmental influences as well as genetic influences, while EF stability is brought about by shared environments. The present findings elucidated the etiology of EF development during the preschool years and confirmed that this period is an important transitional stage for EF development.
