This study builds upon a pilot evaluation of the 1-2-3 Magic Program (Bailey, van der Zwan, Phelan, &; Brooks, 2012 Bailey, E. L., van der Zwan, R., Phelan, T. W., &; Brooks, A. (2012). The 1–2-3 Magic Program: Implementation outcomes of an Australian pilot evaluation with school-aged children. Child &; Family Behavior Therapy, 34(1), 5369. doi:10.1080/07317107.2012.654455[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]), by investigating its long-term efficacy as a brief parenting intervention for families with a school-aged child. Twelve Australian families participated in a randomized controlled trial, assigned either to a wait-listed control group or to one that received immediate training. Consistent with the pilot evaluation, only families who had received training reported significant improvement in child and parenting behavior at an 8-week follow-up assessment. These improvements were maintained for 12-month posttraining, supporting the long-term efficacy of the 1-2-3 Magic Program for Australian families.  相似文献

This aim of this study was to investigate the association between perceived parental religiosity and the quality of the parent–child relationship. Eighty-nine adolescent boys and girls completed the Santa Clara Strength of Religious Faith Questionnaire (SCSRFQ) and the Parent–Child Relationship Survey (PCRS). The results showed that the girls had a better relationship with their mothers than with their fathers, while the boys tended to view their relationships with their father and mother of equal quality. It was also found that greater perceived religiosity of both the fathers and mothers was associated with a better parent–child relationship.  相似文献

2023年发布的《涉及人的生命科学和医学研究伦理审查办法》(以下简称《办法》)首次设立了免除伦理审查制度。该制度设计旨在提升伦理审查效率,但也面临一系列的应用实践挑战。从澄清免除伦理审查的概念入手,简要分析免除伦理审查制度设计的初衷和必要性,同时,以美国为例,介绍了免除伦理审查制度的国际进展以及既往实践的经验教训。最后,针对《办法》提出的免除伦理审查相关要求的重点和难点进行了探讨,并就免除伦理审查的决定主体、标准操作程序,以及免除伦理审查的研究的跟踪审查等应用实践细节提出初步建议。

以往研究关于视觉工作记忆回溯线索效应的产生机制主要存在5种假设,目前依然存在争议。本研究通过改进前人研究实验范式,采用包含内源性回溯线索的颜色回忆报告范式,进一步对这5种假设进行检验。在实验1中,我们调控了线索与探测阵列之间的时间间隔,发现不同时间间隔不影响无线索条件的行为表现,而在正常线索条件中被试的记忆精度以及能记住的项目数量均优于无线索条件;在实验2中,我们对回溯线索伴随的干扰刺激类型进行控制,结果显示,在不同条件下记忆精度不存在差别,但当回溯线索伴随干扰刺激呈现时,被试能记住的项目数量会被降低,降低程度受干扰刺激的类型调制;在实验3中,我们对伴随回溯线索的干扰刺激的呈现时间进行控制,发现虽然回溯线索效应仍然存在,但干扰刺激的呈现时间不会影响效应程度。研究结果表明,回溯线索的出现使得被试能够在决策加工前完成内部注意资源的再分配,从而避免了同时进行这两种认知加工与记忆表征维持本身竞争认知资源。本研究为认知阶段分离假设提供了支持证据,对解决回溯线索效应产生机制的争议以及理解内部注意与视觉工作记忆的关系有重要意义。  相似文献

Kindergarten Ss were presented with 16 pictorial items in four category sets or a partially random ordem with one item from each category composing the four presentation sets. The pictures were presented either on conceptually related background pictures or on white backgrounds. The categorically grouped presentation facilitated free recall performance, both in terms of number of items recalled and the speed with which the items were recalled, and increased the amount of clustering in recall. Categorical clustering in recall was associated with shorter within- than between-category intervals and for those Ss who recalled items from each of four categories successively, the over-all temporal pattern in recall closely approximated that found with adults. No background effects were found.  相似文献

k-SAT is a fundamental constraint satisfaction problem. It involvesS(m), the satisfaction set of the conjunction of m clauses,each clause a disjunction of k literals. The problem has manytheoretical, algorithmic and practical aspects. When the clauses are chosen at random it is anticipated (butnot fully proven) that, as the density parameter m/n (n thenumber of variables) grows, the transition of S(m) to beingempty, is abrupt: It has a "sharp threshold", with probability1 – o(1). In this article we replace the random ensemble analysis by apseudo-random one: Derive the decay rule for individual sequencesof clauses, subject to combinatorial conditions, which in turnhold with probability 1 – o(1). This is carried out under the big relaxation that k is not constantbut k = log n , or even r log log n . Then the decay of S isslow, "near-perfect" (like a radioactive decay), which entailssharp thresholds for the transition-time of S below any givenlevel, down to S = .  相似文献

Research findings show that there is marked variability in children's response to parental separation, but few studies identify the sources of this variation. This prospective longitudinal study examines the factors modifying children's adjustment to parental separation in a community sample of 5,635 families in England. Children's behavioral/emotional problems were assessed when children were aged 47 and 81 months; marital quality, maternal depression, socioeconomic circumstances, and demographic variables were assessed prior to the separation from maternal report. Results indicated that 346 mothers separated from their partners in the 3-year period. Preseparation differences were found for measures of family process and parent risk factors, with effect sizes ranging from small to trivial. Parental separation was associated with a significant but modest increase in behavioral/emotional problems, independent of marital quality, maternal depression, socioeconomic circumstances, and demographic variables. Moderation analyses showed that children of cohabiting parents had a greater increase in adjustment problems following parental separation than children of married parents. Further research elucidating the factors that moderate children's adjustment to parental separation is needed to improve our understanding of who may most likely benefit from preventive interventions.  相似文献

Cooperative play between parents/caregivers and children is a positive and significant contributor to the development of children’s emotional, social, and cognitive skills and may set the stage for the formation of co-occupations. This article discusses the rationale for the development of Parent/Caregiver’s Support of Young Children’s Playfulness (PSYCP), an assessment that is based on children’s play and playfulness, adult’s playfulness, and parent–child interaction. The use of the PSYCP to assess co-occupations will allow therapists to identify the specific behaviors that either hinder or support playfulness and mutual play.  相似文献
