注意分散对老年人错误记忆的影响

该实验以经典DRM词表为实验材料,采用简化后的联合范式来探讨注意资源对老年人错误记忆的影响。比较老年人和青年人在注意集中和注意分散条件下的错误记忆成绩。结果发现,老年组的虚报率显著高于青年人的虚报率,特别在注意集中条件下。更重要的是,老年人在注意集中条件下的虚报率与青年人在注意分散条件下的虚报率相比无显著差异,同时两种条件下的判断标准差异也不显著。结果显示,老年人相比于青年人有更多错误记忆的原因可能是注意资源的不足。     

智力与心理速度的关系研究述评

目前在智力研究领域出现了一种新的研究趋势,研究者开始关注心理计量学智力与认知或生理心理学变量的相关,考察的重点是心理速度,相应的测量指标主要有检测时（IT）、反应时、ERP或神经传导速度,等等。在运用IT任务进行的ERP研究中发现,ERP波幅和潜伏期的不同往往能够反映出智力上的差异。信息加工速度和神经传导速度均与一般智力因素（g因素）存在较高的相关。上述研究发现促进了智力与心理速度关系的跨学科研究,成为智力研究领域中的热点     

气质性乐观与心理健康关系的元分析

运用元分析方法分别探讨了气质性乐观与心理健康的积极指标和消极指标的关系。共有106项研究满足了元分析的标准,涉及气质性乐观与心理健康积极指标的研究有70项,包括83个独立样本(N=30627);涉及气质性乐观与心理健康消极指标的研究有75项,包括105个独立样本(N=39064)。元分析结果发现:(1)整体上气质性乐观与心理健康积极指标有显著正相关(r=0.41),与心理健康消极指标有显著负相关(r=-0.41)。(2)气质性乐观与不同心理健康指标的相关有显著差异,积极指标中,与自尊的相关最高;消极指标中,与抑郁的相关最高。(3)气质性乐观测量工具的差异对其与心理健康的关系没有显著影响。(4)不同年龄阶段群体中气质性乐观与心理健康的关系没有显著差异。(5)文化背景差异对两者的关系有显著影响,西方文化中气质性乐观与心理健康的相关高于东方文化中的相关。     

学习困难青少年认知控制特点研究

本研究基于双重认知控制理论,通过比较学困组和对照组在持续性操作任务上的表现来探究学习困难青少年的认知控制特点。结果发现：（1）在反应性控制的指标上,学困组和对照组的反应时和正确率不存在显著差异,但学困组对探测刺激的辨别力指数更低,显示学困组的反应性控制能力存在一定不足;（2）在主动性控制的指标上,学困组的反应时更长、正确率更低,且对线索刺激的辨别力指数更低,显示学困组在对线索刺激保持的各项指标上都比对照组更差,说明学困组在主动性控制上的缺陷更为明显。     

注意分心对定义一体化编码的影响

通过考察编码阶段注意分心对定义一体化条件下联结记忆成绩的影响,探究定义一体化编码对注意资源的依赖程度。使用注意分心范式,在记忆编码过程操作无分心、奇偶分心和大小分心条件,比较不同注意条件下的联结记忆成绩。结果发现:与无分心条件相比,定义一体化下的联结记忆成绩在两种分心条件下没有显著变化,而造句下的联结记忆成绩在两种分心条件下显著降低。当前发现表明了定义一体化编码较少依赖于注意资源,这深化了对定义一体化编码机制的认识。     

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.     

Training and transfer effects of response inhibition training in children and adults

Response inhibition is crucial for mental and physical health but studies assessing the trainability of this type of inhibition are rare. Thirty‐nine children aged 10‐12 years and 46 adults aged 18‐24 years were assigned to an adaptive go/no‐go inhibition training condition or an active control condition. Transfer of training effects to performance on tasks assessing response inhibition, interference control, working memory updating, task‐switching, and non‐verbal fluid intelligence were assessed during 3‐ and 6‐month follow‐up sessions and/or an immediate post‐training session. Significant training improvements and positive transfer effects to a similar response inhibition task with other stimuli were observed for both children and adults. Reliable albeit short‐lived transfer effects were only found for the children, specifically to working memory updating and task switching. These results suggest some potential for response‐inhibition training programs to enhance aspects of cognitive functioning in children but not adults.     

真实自豪与自大自豪倾向量表的修订及适用

对Tracy和Robins编制的真实自豪与自大自豪倾向量表进行中文版修订并初步考察我国大学生自豪感的特点,分别选取202名和484名大学生进行问卷预测和正式施测。验证性因素分析表明修订后量表仍保持英文版的双维结构,两分量表的α系数为0.785和0.743,重测信度为0.978和0.952。修订后量表具有良好的心理测量学指标,可以用于我国大学生的测试。进一步发现我国大学生的真实自豪显著高于自大自豪,大学生自豪感不存在性别差异,自大自豪存在显著的年级差异。     

COMT基因对注意控制神经基础的调控效应：影像遗传学研究的元分析

为探索注意控制能力个体差异的遗传来源, 当前研究主要关注儿茶酚胺氧位甲基转移酶(catechol-O-Methyltransferase, COMT)基因对参与注意控制加工的前额叶脑区的调控作用。为进一步回答COMT基因是否也对全脑范围的注意脑区具有调控作用, 本文对17篇遗传影像学研究进行元分析。结果发现, COMT基因Val/Val (vv)基因型的被试在注意控制任务下, 不仅前额叶脑区的激活水平高于Met/Met(mm)基因型的被试, 在前扣带回和后扣带回等前额叶之外的脑区激活水平也高于mm基因型的被试, 而且在这些脑区的效应值(vv>mm)都较大(Cohen’s d > 0.8)。由此, 元分析结果表明：COMT基因不仅调控前额叶脑区, 而且对形成注意控制网络的多个脑区都有调控效应。此结果提示注意控制能力的个体差异可能部分的来自于COMT基因对注意控制网络的调控作用。
