The Effect of PTSD Symptom Change on Suicidal Ideation in a Combined Military and Civilian Sample Engaged in Cognitive Processing Therapy

In light of the well-established relationship between posttraumatic stress disorder (PTSD) and suicidal ideation (SI), there has been a push for treatments that simultaneously improve symptoms of PTSD and decrease SI. Using data from a randomized controlled hybrid implementation-effectiveness trial, the current study investigated the effectiveness of Cognitive Processing Therapy (CPT; Resick, Monson, & Chard, 2016) on PTSD and SI. The patient sample (N = 188) was diverse in military and veteran status, gender, and comorbidity, and 73% of the sample endorsed SI at one or more points during CPT. Participants demonstrated significant improvement in SI over the course of CPT. Multilevel growth curve modeling revealed a significant association between PTSD symptom change and change in SI. Results from cross-lagged multilevel regressions indicated that PTSD symptoms predicted SI in the next session, yet SI in a given session did not predict PTSD symptoms in the next session. Potentially relevant clinical factors (i.e., military status, gender, depression diagnosis, baseline SI, study consultation condition) were not associated with the relationship between PTSD symptoms and SI. These results add to the burgeoning literature suggesting that evidence-based treatments for PTSD, like CPT, reduce suicidality in a range of individuals with PTSD, and that this reduction is predicted by improvements in PTSD symptoms.     

道德情绪:探寻道德与创造力关系的新视角

先前有关道德与创造力的关系研究多关注道德的认知与行为差异对创造力产生的影响, 但研究结果却存在较大的分歧。为此, 研究从道德情绪的视角, 对二者的关系进行了系统地梳理, 发现道德情绪存在: 以情绪效价调节创造性认知; 激发道德动机, 中介人格与创造力的关系; 引发自我觉察, 促进顿悟与创造性成就的产生; 提升心理资本, 影响不同创造力特性的表达等, 多种影响个体创造力的路径。这表明, 与道德认知和行为相比, 道德情绪不仅能更加全面准确地体现出个体实际的道德活动、促进符合道德标准的创造力产生; 还为人们解释道德与创造力的关系提供了多样的路径与可能。未来需继续加深对道德情绪及其内在机制的理解、通过系统性地选取创造性任务, 明确道德情绪、道德与创造力之间的关系, 寻找道德培养与创造力激发的新模式。     

父母婚姻冲突对儿童发展的影响及其机制

婚姻关系是家庭关系中最核心的关系, 家庭中父母婚姻冲突影响着儿童发展。众多研究发现, 父母婚姻冲突对儿童认知发展和情绪社会性发展均有重要影响, 而且父母婚姻冲突影响儿童发展存在复杂的作用机制(如中介机制和调节机制)。父母婚姻冲突对儿童发展的影响主要通过儿童认知-情绪过程和家庭过程来实现, 且这一影响会因多种儿童因素和环境因素的不同而不同。未来研究有必要同时考察父母婚姻冲突对儿童认知发展和情绪社会性发展的影响, 并进一步探究和整合多种作用机制, 为干预方案的制定提供有力支持。     

任务设置影响负相容效应的机制——自上而下认知控制对阈下启动信息加工的影响

结合掩蔽启动范式和Go-Nogo范式,考察了任务设置影响负相容效应的机制。实验中以指向左或右的双箭头为掩蔽启动项,在两个Block中的Go试次中分别以箭头和汉字为目标项,要求被试对箭头或汉字做辨别反应,Nogo试次中不呈现目标项,被试无需反应。结果发现:Go试次中,只有在箭头任务设置下才出现负相容效应,脑电结果表现为一致条件下P3潜伏期显著长于不一致条件;Nogo试次中,箭头任务设置下的P3波幅显著大于汉字任务设置下的P3波幅。说明负相容效应受到任务设置这种自上而下认知控制过程的影响,且这种影响发生在阈下启动信息加工阶段。支持注意敏化模型,提示可以在更普遍的角度上理解负相容效应。     

THE FAULT IN US: ETHICS,INFINITY, AND CELESTIAL BODIES

Catherine Keller's Cloud of the Impossible knits together process theology and relational ontology with quantum mechanics. In quantum physics, she finds a new resource for undoing the architecture of classical metaphysics and its location of autonomous human subjects as the primary gears of ethical agency. Keller swarms theology with the quantum perspective, focusing in particular on the phenomenon of quantum entanglement, by which quantum particles are found to remain influential over each other long after they have been physically separated—what Albert Einstein and his collaborators recklessly dismissed as “spooky action at a distance.” This spooky action, Keller suggests, reroutes process thought—classically concerned with flux—to a new concern with intransigence—particularly the intransigence of the ethical relationship. Attending to the ethical urgency of the Other, she leaves process theology in a position of susceptibility to the moral imperative posed by the marginalized, the victimized, and the oppressed. This essay argues that although the ontological work of Keller's book productively integrates quantum physics into process theology, the ethical dimension of relationality is left cold in the quantum field. This is because, contra the ethical framework of contemporary deconstruction, which, following Emmanuel Levinas, sees ethical relationships as emerging out of a dynamic of infinite distance, moral connection has nothing to do with the remote reaches of the quantum scale or the macro‐scale limits of space—nothing to do with “infinity” at all. Ethics emerges out of a much messier landscape—the evolved dynamic of fleshy, finite, material bodies. Rather than seeing ethical labor as a matter of physics, my contention (and here I think I am arguing with, rather than against Keller) is that interdisciplinary undertakings like Cloud of the Impossible are ethical disciplinary practices, re‐acquainting us with the non‐sovereignty of the self in order to open up new habits of relating rather than spotlighting ethical imperatives.     

Intertemporal Similarity: Discounting as a Last Resort

Standard models of intertemporal choice assume that individuals discount future payoffs by integrating reward amounts and time delays to generate a discounted value. Alternative models propose that, rather than integrate across them, individuals compare within attributes (amounts and delays) to determine if differences in one attribute outweigh differences in another attribute. For instance, the similarity model 1) compares the two reward amounts to determine whether they are similar, 2) compares the similarity of the two time delays, and then 3) makes a decision based on these similarity judgments. Here, I tested discounting models against attribute‐based models that use similarity judgments to make choices. I collected intertemporal choices and similarity judgments for the reward amounts and time delays from participants in three experiments. All experiments tested the ability of discounting and similarity models to predict intertemporal choices. Model generalization analyses showed that the best predicting models started with similarity judgments and then, if similarity failed to make a prediction, resorted to discounting models. Similarity judgments also matched intertemporal choice data demonstrating both the magnitude and sign effects, thereby accounting for behavioral data that contradict many discounting models. These results highlight the possibility that attribute‐based models such as the similarity models provide alternatives to discounting that may offer insights into the process of making intertemporal choices.

Eye Movements in Strategic Choice

In risky and other multiattribute choices, the process of choosing is well described by random walk or drift diffusion models in which evidence is accumulated over time to threshold. In strategic choices, level‐k and cognitive hierarchy models have been offered as accounts of the choice process, in which people simulate the choice processes of their opponents or partners. We recorded the eye movements in 2 × 2 symmetric games including dominance‐solvable games like prisoner's dilemma and asymmetric coordination games like stag hunt and hawk–dove. The evidence was most consistent with the accumulation of payoff differences over time: we found longer duration choices with more fixations when payoffs differences were more finely balanced, an emerging bias to gaze more at the payoffs for the action ultimately chosen, and that a simple count of transitions between payoffs—whether or not the comparison is strategically informative—was strongly associated with the final choice. The accumulator models do account for these strategic choice process measures, but the level‐k and cognitive hierarchy models do not. © 2015 The Authors.

Individuals with pronounced schizotypal traits are particularly successful in tickling themselves

We assessed self-tickling sensations in a group of participants high in schizotypal traits (n = 27) and group of participants low in schizotypal traits (n = 27). The groups were formed by screening a pool of 397 students for extreme scores in the French version of the Schizotypal Personality Questionnaire. As observed in a previous study involving psychiatric people with auditory hallucinations and/or passivity experiences our results showed that self-applied tactile stimulations are felt to be more ticklish by healthy individuals high in schizotypal traits. In contrast, there were no significant intergroup differences in the mean tickle rating in the externally-produced tickling condition. Furthermore, more successful self-tickling was associated with more frequent self-reports of unusual perceptual experiences (such as supernatural experiences) and passivity experiences in particular (such as a feeling of being under the control of an outside force or power).     

A case for taking the dual role of counsellor-researcher in qualitative research

There is ongoing debate about whether the challenges of practice-based research in counselling, with clients’ discourses providing the raw data, can be overcome. This article begins by considering the argument of whether taking a dual role of counsellor-researcher within case study research is a legitimate qualitative approach. A case example using sand-tray in short-term therapy with adults from a pluralistic perspective is provided to demonstrate how the challenges of the dual role can be managed to produce effective research findings. It is suggested that this approach closes the gap between research and practice to produce findings that are highly relevant to the counselling context. The ethical considerations of taking a dual role of counsellor-researcher are considered, and opportunities and challenges when adopting this approach are identified.
