双语言语产生中的词汇提取机制

文章主要介绍了双语言语产生中词汇提取机制的两种理论：非特定语言提取的理论和特定语言提取的理论。重点围绕着双语言语产生中词汇提取的一个关键问题,即非目标语言的词汇是否对目标语言的词汇提取形成竞争或者干扰详细地论述了二者的理论分歧,非特定语言提取的理论认为非目标语言的词汇会对目标语言的词汇提取形成竞争,而特定语言提取的理论认为不会形成竞争。文章最后介绍了双语言语产生中词汇提取机制的最新研究趋势,表明了非特定语言提取的理论和特定语言提取的理论逐步走向融和     

工作记忆训练及对数学能力的迁移作用

工作记忆缺陷会影响个体数学能力发展。通过记忆策略、广度、刷新、转换等功能的工作记忆训练,可以改善个体认知功能。然而,工作记忆训练对个体的阅读、数学、流体智力等方面的远迁移效果并不一致。研究表明,工作记忆训练可以改善数感、视觉空间能力、推理能力等数学一般技能;也会通过改善语音工作记忆以及空间能力促进数学计算能力,或者通过改善中央执行系统,提升数学问题表征、模式识别、解题迁移、策略选择等复杂的过程,从而促进数学问题解决能力。因此,区分不同数学任务的认知过程,可以获得工作记忆训练对数学能力迁移效果的进一步证据。今后,神经影像学的证据或许也是未来工作记忆训练对数学能力提高的又一佐证。     

Influence of the large–small split effect on strategy choice in complex subtraction

Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size.     

政策执行偏差严重程度对公众地方政府 责任判断的影响:多重中介模型的检验

为探讨地方政府政策执行偏差严重程度对公众地方政府责任判断的影响机制。采用问卷法对678名社会公众进行调查,结果显示:(1)地方政府政策执行偏差情境下,公众地方政府愿望判断和公众地方政府信念判断在政策执行偏差严重程度和公众地方政府责任判断之间起多重中介作用。(2)公众地方政府信念判断在政策执行偏差严重程度和公众地方政府责任判断之间的中介效应量大于公众地方政府愿望判断的中介效应量。     

Conducting community‐based participatory research in an urban Malaysian community: Lessons learned and challenges in establishing partnerships

This paper presents the process of how partnerships are established between an urban residential community and an academic institution in Malaysia by employing community‐based participatory research, which involves researchers, community members, and organizational representatives as coresearchers. The research process encompasses colearning, power sharing, and coconstructing of knowledge, with the community members driving the research direction. The research paradigm is grounded on conducting research with the community. This paper highlights the experience and lessons learned while applying the principles of community‐based participatory research that promotes social participation of older persons living in a residential community. Two pertinent challenges surface in the research process. The first challenge involves the complexity noted in the gap between the emancipation of community‐based participatory research and the hierarchical social structure of the society. The second challenge is the prevalence of unspoken yet subtle domination that undermines the local cultural values affecting the process of coconstructing knowledge with the community. Recommendations for addressing these challenges include future partnerships with other Malaysian communities as well as cross‐border research partnerships.     

Evaluating the Effectiveness of a Group CBT for Parents of ADHD Children

Improvements in parenting skills do not necessarily lead to improvements in child and parent outcomes for children with attention deficit and hyperactivity disorder (ADHD). Cognitive factors such as parental cognitions and parenting self-efficacy may influence such outcomes. Clinical research on the effects of cognitive-behaviour therapy (CBT) on parental cognitions, parenting self-efficacy and mental health in Chinese parents of children with ADHD is lacking. This quasi-experimental study intended to assess the effects of a culturally attuned group CBT treatment on the mental health and quality of life of Chinese parents aged 26–58 years, with children with ADHD in Hong Kong. Participants in the experimental group received group CBT and standard treatment and their counterparts in the control group received standard treatment. Primary outcome variables of mental health and quality of life and process variables including parenting stress, parenting efficacy and dysfunctional attitudes were measured at baseline, post-treatment and 3-month follow-up. Data were analysed using 2?×?3 ANCOVAs, Cohen’s d statistics and multiple mediation analyses. Group by time interactions were found for most outcome variables. Effect size statistics indicated that group CBT had small to moderate effects on most outcome variables at post-treatment and follow-up assessments. The effect of CBT on mental health was mediated by the reduction in parenting stress and the effect of CBT on quality of life was mediated by the reductions in parenting stress and dysfunctional attitudes. Given its potential benefit, it is worth considering incorporating this group CBT programme into interventions for Chinese parents with ADHD children.     

心血管疾病发生的生物钟现象与时间治疗学

生物钟是生物为了适应其生存环境周而复始的变化(如昼夜变化、四季变化等)在长期进化过程中形成的机体固有节律.研究表明生物钟节律的异常参与了心血管疾病的发生、发展.因此通过研究血管疾病的发生与生物钟的关系,建立新的治疗方法,即时间治疗学,来治疗和预防心血管疾病.     

下肢深静脉血栓形成的治疗进展

下肢深静脉血栓形成在欧美是一种比较常见的疾病,在我国随着临床医师意识的加强及诊疗水平的提高,其发病率也逐年上升。下肢深静脉血栓形成的危害是其并发症一肺栓塞和血栓形成后综合征,肺栓塞是临床上导致死亡的一个重要原因,而血栓形成后综合征严重影响患者的生活质量及工作能力,故其治疗成为一个热门话题。本文对下肢深静脉血栓形成的治疗...     

维吾尔族三语者的非熟练第三语言的概念表征特征

使用跨语言启动条件下的真假词汇判断任务,以母语为维语,第二语言为汉语,第三语言为英语的维吾尔族大学生为被试。通过两个实验探讨了维吾尔族三语者不熟练的第三语言的语义表征特点,即他们的第三语言的语义是共同存储还是独立存储问题。结果发现,跨语言的启动条件下,在实验一,启动刺激（维语）与目标刺激（英语）之间具有语义联想关系时,产生了显著的启动效应。在实验二,启动刺激（英语）与目标刺激（维语）之间没有产生语义启动效应。这些结果表明,被试的第三语言的语义概念表征是同第一语言的概念表征共同存储的;被试的母语较容易启动第三语言,但非熟练的第三语言不太容易启动母语,这是因为被试的第三语言还没有达到一定程度的熟练水平。     

Unconscious structural knowledge of form-meaning connections

We investigated the implicit learning of a linguistically relevant variable (animacy) in a natural language context (namely, the relation of forms of determiners to semantics). Trial by trial subjective measures indicated that exposure to a form–animacy regularity led to unconscious knowledge of that regularity. Under the same conditions, people did not learn about another form–meaning regularity when a linguistically arbitrary variable was used instead of animacy (size relative to a dog). Implicit learning is constrained to acquire unconscious knowledge about features with high prior probabilities of being relevant in that domain.
