Multimedia Field Test Thinking About Exposures? There’s an App for That!

Anxiety Coach is a smartphone application (“app”) for iOS devices that is billed as a self-help program for anxiety in youth and adults. The app is currently available in the iTunes store for a one-time fee of $4.99. Anxiety Coach is organized around three related content areas: (a) self-monitoring of anxiety symptoms, (b) learning about anxiety and its treatment, and (c) guiding users through the development of a fear hierarchy and completion of exposure tasks. Although the app includes psychoeducation about anxiety as well as information regarding specific skills individuals can use to cope with anxiety (e.g., cognitive restructuring), the primary focus of the app is on exposure tasks. As such, the app includes a large library of potential exposure tasks that are relevant to treating common fears and worries, making Anxiety Coach useful to clients and clinicians alike. Additionally, Anxiety Coach prompts users to provide fear ratings while they are carrying out an exposure task and displays a message instructing users to stop the exposure once fear ratings drop by half. These features work together to create an app that has the potential to greatly increase the reach of exposure-based cognitive behavioral therapy for anxiety.     

认知诊断CAT中项目曝光控制方法的比较

项目曝光率关系到题库建设和测验安全,是计算机化自适应测验(Computerized Adaptive Testing, CAT)需要考虑的重要问题。在认知诊断 CAT 情形下,首先基于传统 CAT 中 a-分层方法的思想提出按项目信息量对题库分层的分层多阶段(Stratified Multistage, SM)选题方法;然后将 SM 方法与项目合格(Item Eligibility, IE)方法相结合得到SMIE方法。在此基础上,开展模拟研究比较SM、IE、SMIE、最大修正优先指标(Maximum Modified Priority Index, MMPI)方法、限制阈值(Restrictive Threshold, RT)方法和限制进度(Restrictive Progressive, RPG)方法的选题表现。总体上,它们的测量精度从高到低依次为IE、SM、SMIE、RT、RPG和MMPI方法;项目曝光分布均匀性的优劣次序为MMPI、RPG、SMIE、RT、SM和IE方法;SMIE和RT方法能较好地平衡测量精度和项目曝光均匀性要求。     

自尊水平、事件效价与时距对过去事件时距估计的影响

在西方文化背景下提出的时间自我评价理论认为,人们为了维护当前积极自尊,主观上会远离过去失败而亲近过去成功。本研究采用线段评估法,选取311名中国大学生被试,通过两个实验考察自尊水平、事件效价与时距对过去事件时距估计的影响,以检验该理论的文化普适性。结果表明:对过去事件的时距估计,自尊水平、事件效价及其交互作用在同一时距里均不存在显著差异;时距的主效应及其与事件效价的交互作用均显著,在负效价水平上存在显著时距差异,在正效价水平上无显著时距差异。研究结果不支持基于西方文化背景下的时间自我评价理论。     

东西方面孔异族效应机理的电生理学证据

采取事件相关电位方法研究东西方面孔记忆编码的差异（DM效应）,从而阐明异族效应的神经机制。14名被试学习和再认东西方面孔照片的实验结果表明,无论记住与否,西方面孔产生的早期成分（潜伏期70~220ms）在头皮额部有一个比东方面孔更为正向的变化,表明在此阶段更多的资源分配于异族面孔,支持异族效应产生的特征选择假说。无论东方面孔还是西方面孔,记住与未记住相比较,则在额部和顶部产生潜伏期在晚期正成分（LPC）范围的正走向变化,但西方面孔在240~320ms潜伏期范围内,DM效应较小。另外,东方面孔在枕部诱发出一个明显的负波N260,而西方面孔产生的N260很小甚至没有,反映了大脑对不同种族面孔的编码机制有所不同,因而可能被称为“种族特异波”     

归因是怎样影响假设思维的

考察了归因这一外力对假设思维的影响。研究发现归因对假设思维的影响与选择原因大小成正比与事件后果严重程度成反比。当选择原因相对后果而言足够大时,假设思维将不服从“特例－常规”规律。在此基础上,根据是否存在外力将事件分为被迫事件和自由事件,并提出“特例－常规”规律（或是“做－不做”规律）只适合自由事件而不是所有事件。这一结果部分地解释了长期存在于实验研究与现场研究中的假设思维所表现出的差异。     

基于职业发展的大学生核心素质模型的研究

基于职业发展的大学生核心素质模型是对大学生必备核心素质的初步探讨。在文献分析和访谈6位相关专家的基础上得到《大学生核心素质(行为)词典》,包括21项核心素质的定义、行为指标描述及其对应等级分数。对优秀和一般两组各10名毕业生进行行为事件访谈,编码分析后得到大学生核心素质初步模型,包括踏实、学习发展、责任心、自信、人际交往、口头表达、坚持性和成就导向这8个维度。     

Children’s Perspectives of an Enhanced Cognitive-Behavioral Treatment for Child–Parent Dyads With Anxiety Disorders

Prior research has extensively evaluated the efficacy of cognitive-behavioral therapy (CBT) for child anxiety disorders—however, few studies have investigated anxious children’s perspectives and experiences of participating in CBT. This qualitative study explored children’s acceptability of a newly developed enhanced CBT intervention, designed specifically for the treatment of anxiety disorders in children with a clinically anxious parent. The study also explored children’s perceptions and experiences of individual (child only) and joint observational (child–parent) exposure activities that were key to the intervention. Ten children (age range 6–11, M = 8.5 years) and their mothers (age range 34–45, M = 39.5 years) completed in-depth semistructured interviews to investigate child participants’ anticipated and experiential acceptability of the enhanced CBT intervention. Thematic analysis revealed seven major themes broadly reflecting the acceptability, appropriateness, and perceived benefit of the intervention elements, with particular value credited to exposure tasks and the dyadic nature of the intervention. Findings suggest that future experimental evaluation of the enhanced intervention is warranted. Further, the study highlights that CBT for child anxiety disorders, where exposure work is a feature, is acceptable and perceived to be effective by its intended treatment recipients.
