责任对后悔强度的影响：来自ERP的证据

采用事件相关电位技术,研究责任对后悔的影响。实验采用赌博范式,主要因素是被试对于负性结果所负责任的大小,分为三个水平：1（只有被试一人犯错）、1/2（被试和另外一个人犯错）以及1/3（三人同时犯错）。研究结果发现,被试主观评定的情绪强度和责任感上,1条件下的显著大于1/2和1/3条件下的,而1/2和1/3条件无显著差异;被试的反事实思维则在三个水平上差异显著,责任越大,反事实思维越强。fERN（feedback error-related negativity,反馈错误相关负波,也称FRN,反馈负波）的波幅在1条件下的显著大于1/2和1/3条件下的,而1/2和1/3条件下的无显著差异;而P300的波幅则在三种水平上差异显著,责任越大,波幅越小。结果支持责任对后悔强度有所影响,且后悔强度在一定程度上随责任大小呈线性变化。

The contribution of visual processing to academic achievement in adolescents born extremely preterm or extremely low birth weight

Children born extremely preterm (EP, <28 weeks) and/or extremely low birth weight (ELBW, <1000 g) have more academic deficiencies than their term-born peers, which may be due to problems with visual processing. The aim of this study is to determine (1) if visual processing is related to poor academic outcomes in EP/ELBW adolescents, and (2) how much of the variance in academic achievement in EP/ELBW adolescents is explained by visual processing ability after controlling for perinatal risk factors and other known contributors to academic performance, particularly attention and working memory. A geographically determined cohort of 228 surviving EP/ELBW adolescents (mean age 17 years) was studied. The relationships between measures of visual processing (visual acuity, binocular stereopsis, eye convergence, and visual perception) and academic achievement were explored within the EP/ELBW group. Analyses were repeated controlling for perinatal and social risk, and measures of attention and working memory. It was found that visual acuity, convergence and visual perception are related to scores for academic achievement on univariable regression analyses. After controlling for potential confounds (perinatal and social risk, working memory and attention), visual acuity, convergence and visual perception remained associated with reading and math computation, but only convergence and visual perception are related to spelling. The additional variance explained by visual processing is up to 6.6% for reading, 2.7% for spelling, and 2.2% for math computation. None of the visual processing variables or visual motor integration are associated with handwriting on multivariable analysis. Working memory is generally a stronger predictor of reading, spelling, and math computation than visual processing. It was concluded that visual processing difficulties are significantly related to academic outcomes in EP/ELBW adolescents; therefore, specific attention should be paid to academic remediation strategies incorporating the management of working memory and visual processing in EP/ELBW children.     

Ethically Problematic Value Change as an Outcome of Psychotherapeutic Interventions

Values nonpaternalism—the ethical imperative to avoid imposing values onto clients—is implicit in most widely used ethical frameworks employed by psychotherapists. Although changes in client values may represent desired psychotherapeutic outcomes, some such changes may be ethically problematic. Interventions are characterized by values paternalism when they are intended to promote client welfare but are accompanied by impositions against client values. Providers and consumers of psychotherapy may routinely lack awareness of this consideration. Psychotherapists may have a duty to be informed about ethically problematic value change accompanying psychotherapy and to inform clients about this phenomenon.     

Psychodynamic psychotherapy for children and adolescents: an updated narrative review of the evidence base

While the evidence base for psychodynamic therapy with adults is now quite substantial, there is still a lack of research evaluating the effectiveness of psychodynamic therapies with children and young people. Those studies that have been carried out are also not widely known in the field. To help address the second point, in 2011, we carried out a review of the evidence base for psychodynamic psychotherapy for children and adolescents, which identified 35 studies which together provided some preliminary evidence for this treatment for a range of childhood disorders. The present study is an updated review, focusing on research published between March 2011 and November 2016. During this period, 23 additional studies were published, of which 5 were reports on randomised controlled trials, 3 were quasi-experimental controlled studies and 15 were observational studies. Although most studies covered children with mixed diagnoses, there were a number of studies examining specific diagnostic groups, including children with depression, anxiety and disruptive disorders. whilst the quality of studies was mixed, some were well-designed and reported, and overall indicated promising findings. Nevertheless, further high-quality research is needed in order to better understand the effectiveness of psychodynamic psychotherapy across a range of different disorders, and to ensure that services can provide a range of evidence-based treatments for children and young people.     

Adaptive scaling of reward in episodic memory: a replication study

Reward is thought to enhance episodic memory formation via dopaminergic consolidation. Bunzeck, Dayan, Dolan, and Duzel [(2010). A common mechanism for adaptive scaling of reward and novelty. Human Brain Mapping, 31, 1380–1394] provided functional magnetic resonance imaging (fMRI) and behavioural evidence that reward and episodic memory systems are sensitive to the contextual value of a reward—whether it is relatively higher or lower—as opposed to absolute value or prediction error. We carried out a direct replication of their behavioural study and did not replicate their finding that memory performance associated with reward follows this pattern of adaptive scaling. An effect of reward outcome was in the opposite direction to that in the original study, with lower reward outcomes leading to better memory than higher outcomes. There was a marginal effect of reward context, suggesting that expected value affected memory performance. We discuss the robustness of the reward memory relationship to variations in reward context, and whether other reward-related factors have a more reliable influence on episodic memory.     

积极心理资本的结构、功能及干预研究述评*

积极心理资本自提出以来,便备受关注,它超越了人力资本和社会资本,是一种能够被有效开发和管理,并能够对个体的绩效产生重要影响的核心积极心理要素。在以往研究中,研究者提出了积极心理资本的四维结构说、三维结构说和多维结构说,并据此开发了相应的测量工具。在后果变量方面,主要探讨的是积极心理资本与工作态度、工作行为、工作绩效、幸福感等方面的关系。积极心理资本自身也是一个重要的中介与调节变量,而PCI干预模型可有效提高个体的心理资本水平。今后研究的重点包括研究对象与内容的拓宽、研究方法的改进与完善以及本土化和跨文化研究的加强等。
