Intrusive images in PTSD and in traumatised and non-traumatised depressed patients: a cross-sectional clinical study

Although intrusive images are a hallmark of post-traumatic stress disorder (PTSD) and also occur in depression, little is known about the differences and similarities of such images in these conditions. Our study focuses on the qualities and triggers of intrusive images and responses to them in three groups--patients with PTSD, and depressed patients with and without trauma (n=65)-to highlight the diagnostic specificity of intrusive images for PTSD and depression. We distinguished intrusive images from verbal intrusive cognitions such as rumination and intrusive (brief) lexical thoughts. Consistent with the literature, the intrusive images of PTSD patients had a more "here-and-now quality" and were perceived more visually compared to those of both depressed groups. The groups showed a good deal of similarity concerning other image qualities. Most importantly, the intrusive images in PTSD and depressed patients with and without trauma were perceived as similarly distressing. Rumination and intrusive (brief) lexical thoughts were two of the five most named triggers of intrusive images. Limitations, such as the lack of a control group, and the clinical implications of these results are discussed, demonstrating the need to help non-PTSD patients with and without trauma to deal with intrusive images.     

The search for an effective clinical behavior analysis: the nonlinear thinking of Israel goldiamond

This paper has two purposes; the first is to reintroduce Goldiamond's constructional approach to clinical behavior analysis and to the field of behavior analysis as a whole, which, unfortunately, remains largely unaware of his nonlinear functional analysis and its implications. The approach is not simply a set of clinical techniques; instead it describes how basic, applied, and formal analyses may intersect to provide behavior-analytic solutions where the emphasis is on consequential selection. The paper takes the reader through a cumulative series of explorations, discoveries, and insights that hopefully brings the reader into contact with the power and comprehensiveness of Goldiamond's approach, and leads to an investigation of the original works cited. The second purpose is to provide the context of a life of scientific discovery that attempts to elucidate the variables and events that informed one of the most extraordinary scientific journeys in the history of behavior analysis, and expose the reader (especially young ones) to the exciting process of discovery followed by one of the field's most brilliant thinkers. One may perhaps consider this article a tribute to Goldiamond and his work, but the tribute is really to the process of scientific discovery over a professional lifetime.     

Is Retirement Good or Bad for Subjective Well-Being?

Retirement has been viewed either as a transition that is accompanied by psychological distress or as a time of continued, or even enhanced, subjective well-being. Existing evidence is mixed, with some studies reporting retirement as positively related to well-being and others reporting a negative relationship or none at all. Our research indicates that developmental and social contexts shape an individual’s retirement decisions and experiences, so that retirement should be studied in its ecological and life-course context. Research on marital quality and subjective well-being in retirement has demonstrated both similarities and differences between men and women, as well as the need to consider couples conjointly (rather than viewing individuals in isolation). Future research focusing on the retirement process as it unfolds over time and in ecological context can serve to illuminate the circumstances under which retirement promotes or detracts from the quality of life.     

交互视角下工作重塑干预的影响效应整合模型

作为一种引导员工主动改变工作的行为, 工作重塑干预成为近年来组织行为学领域研究的重要主题。基于现有研究成果, 系统梳理了工作重塑干预的概念和分类。依据角色-资源接近-回避模型, 归纳和提炼了工作干预的影响效果, 在此基础上, 借鉴AMO理论, 分别从重塑能力(Ability)、重塑动机(Motivation)和重塑机会(Opportunity)层面, 构建了个体和组织交互情境下的工作重塑干预内在影响机制, 进而提出了一个整合性的理论分析框架, 为当前开展工作重塑干预的相关研究提供一定的借鉴和参考。未来研究应更多关注基于中国情境的工作重塑干预影响因素及作用机制。     

权力接近−抑制行为理论:基于元分析的理论拓展

权力接近−抑制行为理论是解释权力和行为关系的重要理论, 但应用该理论的实证研究却存在与理论相矛盾的结论。通过对2003~2023年探索权力与接近和抑制行为关系的154篇文献、245个实证样本的261个效应值的元分析整合, 本研究检验了权力与接近−抑制行为关系的双刃剑作用机制及边界条件, 以期解释以往研究结论不一致的原因。结果显示权力与接近−抑制行为的关系具有双刃剑效应, 客观权力既会通过主观权力间接增加接近行为并减少抑制行为, 也会对抑制行为产生直接的促进作用, 且主观权力对行为的解释力强于客观权力。调节效应结果显示, 权力距离能够加强主观权力对接近行为的正向影响, 并强化主观权力对抑制行为的负向影响。上述结论有助于深化和拓展权力接近−抑制行为理论框架。     

舌尖效应产生和解决的词汇提取年老化机制：两阶段范式研究

舌尖效应年老化机制受语言特异性因素的影响。本研究把Stroop效应作为协变量,在统计分析控制个体抑制能力的基础上,采用两阶段范式考察舌尖效应产生和解决过程中词汇提取的年老化机制。结果发现：（1）老年人的舌尖效应产生率和语音提取缺陷均显著高于青年人,而语义提取缺陷的年龄差异不显著;（2）老年人的舌尖效应解决率和语音促进效应量均显著低于青年人;（3）语义启动影响老年人舌尖效应解决时的语言促进效应,而对青年人没有影响。上述结果表明,舌尖效应产生和解决的词汇提取年老化与语音提取衰退有关,与语义提取衰退无关,支持语言特异性衰退的观点。     

原则主义的理论进路、伦理争论及其启示

原则主义作为全球生命伦理学最有影响力的理论进路,是对生命伦理学作为一门学科问题的回答,也是经典哲学理论在该领域中脆弱性的必然结果。然而,自产生伊始,原则主义就深陷批评和质疑的漩涡之中,包含原则一致性、常识道德问题、道德地位和方法论等。对这些争论的回应和批评性意见的包容、选择性吸纳,使原则主义释放出强大的理论生命力。原则主义本质上是对于生命伦理学的思考,对于我们参与全球生命伦理学发展提供中国话语给予深刻启示。

     

汉语阅读中词切分研究进展

词切分指读者在文本阅读过程中将词从句子或语篇中切分出来以促进文本阅读与加工的过程。本文对近20 年来汉语词切分研究成果总结发现:词间空格、词素特性、词意识、词汇预期均可作为词切分的依据; 汉语阅读存在词n和词n+1两种切分,两种切分过程中字词加工均遵循交互激活假设,切分词n过程中字词加工的交互激活特点表现为字词同等相互影响,切分词n+1过程中字词加工的交互激活特点更多表现为词汇加工影响字加工; 重叠歧义词切分遵循多重激活假设,其中被激活的单词之间的竞争机制符合竞争假设,左侧词汇在这一竞争中具有优势,此外,重叠歧义词的切分受到词频,语境的影响。     

回避与趋近性负性人格特质对应激心血管反应模式的不同影响

本研究考察了回避与趋近性负性特质对不同强度心理社会应激刺激重复暴露的心血管反应、应激后心血管反应恢复、重复应激心血管反应的影响,并探讨了应激认知评价在其中的作用。167名大学生被试被随机分配到中/高强度应激条件中,连续采集其在基线期、首次应激期、恢复期、重复应激期四个阶段的心血管反应数据。结果发现:(1)无论应激强度如何,回避性负性特质预测首次和重复应激中较低(钝化)的心血管反应和应激后较差的恢复,而趋近性负性特质预测较大的心血管反应和应激后较差的恢复。(2)重复应激个人资源感知在回避性负性特质与重复应激心率反应之间起中介作用。因此,回避性负性特质与持续较低(钝化)的应激心血管反应和应激后较差的恢复相联系,而趋近性负性特质与较大的应激心血管反应和应激后较差的恢复相联系,即两类负性特质均表现出不适应的固化的应激心血管反应模式,这可能构成了两类不同负性特质增加罹患心血管疾病风险的生理机制。     

语言范畴可否引起偏侧化颜色范畴知觉？

本研究考查了语言范畴是否会引起偏侧化颜色范畴知觉,并探讨了偏侧化颜色范畴知觉是语言范畴即时分类颜色还是长期与颜色联结的结果。实验中,以测量差别阈限的方法选定的渐变、相邻颜色知觉距离相当的A、B、C、D四种颜色（A、B为绿色,C、D为蓝色）为材料,以色词与颜色重组模式训练被试用4个人造词汇分别命名4种颜色,并让被试在训练前、第一次训练和第八次训练后均完成视觉搜索任务测试。经训练,原范畴内颜色（AB,CD）变成了范畴间颜色,原范畴间颜色（BC）仍为范畴间颜色。结果显示：被试在一次训练后能以新名字区分4种颜色,八次训练后掌握了4种颜色的新名字;在训练前测试中,出现了与蓝绿色相应的偏侧化颜色范畴知觉;在第八次训练后测试中,出现了与习得的语言范畴相应的偏侧化颜色范畴知觉,但在第一次训练后测试中并未出现这一效应。这些结果表明,语言范畴能引起偏侧化颜色范畴知觉,偏侧化颜色范畴知觉是语言范畴长期与颜色联结,而非即时分类颜色的结果。
