An Integrative View of Conflict Adaptation and Active Maintenance

The conflict adaptation (CA) effect refers to the reduction in the interference effect observed in conflict tasks that follow incongruent compared to congruent trials. It has been suggested that CA is caused by the exertion of flexible cognitive control, supported by many behavioral and neuroimaging studies; however, it remains unclear how conflict‐related features of the preceding trial are conveyed to subsequent trials for following adaptation. This review aims to summarize evidence supporting the top‐down modulation of the dorsolateral prefrontal cortex and passive short‐term maintenance in the posterior brain areas as mechanisms underlying CA, respectively, and to suggest a new integrated view of CA, including active maintenance in working memory. We review empirical evidences suggesting that both dorsolateral prefrontal cortex and posterior brain regions play critical roles in CA, rather than either top‐down modulation or passive maintenance alone. Although the active maintenance view of CA appears to explain many existing findings, empirical studies are required to directly test this view.     

Critical reflection in midwifery practice: the protection motivation theory

Background: The aim of this paper is to shed light on the notion of fear and inter-personal working relationships, and to promote safe midwifery practice, by critically reflecting on our practice and being aware of fear appeals and the protection motivation theory (PMT).

Theory: PMT provides a general account of the impact of persuasive communication, emphasising the cognitive processes that mediate behaviour change and questions whether ‘fear appeals’ could influence behaviour. Discussion: It is possible that when a midwife decides on a particular care pathway, she determines the degree and perception of the four elements of the PMT; severity, vulnerability, response-efficacy and self-efficacy. If the midwife decides that both the degree of severity and her perception of vulnerability are high, whereas response and self-efficacy perceptions are low, she will probably decide against her original care pathway. For the PMT to be used safely, an appropriate judgement call is required and is based on full understanding of the situation, effective communication with the multidisciplinary team, full knowledge of the proposed care, and competence and confidence in the proposed care. Conclusion: By critically reflecting on their practice and using the PMT, the author believes that midwives will be able to work in partnership with obstetricians to provide safe and effective care within their sphere of practice and in the absence of fear.     

When Living and Working Well Together in Organizations Changes Into Good Social Coexistence: The Talent Club Case

In our contemporary age, where a combination of individualism and mutual distrust is unhappily common among people and society is “liquid” and disoriented, so-called intermediate units (groups, associations) are a precious resource that promotes positive coexistence within organizations and in local communities, too. The present contribution describes an example of such an intermediate unit, the Talent Club, located in a peripheral neighborhood of a metropolitan area in northern Italy. This case study shows the development of positive living and working together in organizations and their transformation in the tool for community development and good coexistence. Qualitative and quantitative data show that the relational aspect is crucial because it promotes authentic exchange among people, supporting participation and social cohesion against self-referential habits and isolation. Although at present the Talent Club is mostly functioning in a affiliating coexistence among members, seeds of a more generative coexistence are clearly detectable.     

任务无关情绪刺激对工作记忆信息更新的影响:来自ERP的证据

任务无关的情绪刺激如何对工作记忆的信息更新过程产生影响还不清楚。本研究采用情绪N-back任务,结合事件相关电位技术调查情绪对工作记忆信息更新的影响。ERP结果显示,在0-back任务中,负性分心物诱发的P3显著小于中性分心物,表明其干扰了工作记忆信息更新过程;而在2-back任务中,负性分心物诱发的P3与中性分心物没有显著差异,表明其未对信息更新表现出干扰效应。该结果支持了情绪与认知加工的双竞争模型。     

注意缺陷多动障碍(ADHD)儿童的工作记忆:基础加工缺陷还是执行功能问题

为探索注意缺陷多动障碍(ADHD)儿童言语工作记忆缺陷的机制,研究采用了言语n-back任务比较了正常儿童与注意缺陷多动障碍儿童的工作记忆成绩。结果表明:在更新水平为0次时,ADHD儿童与正常儿童的成绩没有显著差异,但在更新水平为1次和2次时,ADHD儿童的记忆成绩均显著低于正常儿童,效应量指标(Cohen′d)分别达到了1.31和1.63;另外,在更新难度对记忆成绩的影响上,ADHD儿童表现出了更大的更新代价,效应量指标(Cohen′d)达到了1.54,处在很高的水平。结论认为ADHD儿童在记忆的基础性加工上并不存在明显缺陷,其更大的更新代价表明ADHD儿童在言语工作记忆的执行加工(更新操作)上的缺陷。     

绩效考核满意度对工作退缩行为的影响:有调节的中介效应

绩效考核满意度对员工工作行为的影响和作用机制一直是组织行为领域研究的重点。本研究采用《绩效考核满意度量表》、《在职行为量表》等研究工具,抽取419名在职员工,考察绩效考核满意度与工作退缩行为之间的关系以及组织公平感、道德型领导在其二者关系上的作用机制。结果发现:(1)绩效考核满意度与工作退缩行为之间存在显著负相关。(2)道德型领导调节绩效考核满意度和组织公平感之间的关系。(3)道德型领导调节绩效考核满意度和工作退缩行为之间的关系。(4)道德型领导和绩效考核满意度的交互作用通过分配公平、程序公平影响工作退缩行为。     

Attentional effects on orientation judgements are dependent on memory consolidation processes

Are the effects of memory and attention on perception synergistic, antagonistic, or independent? Tested separately, memory and attention have been shown to affect the accuracy of orientation judgements. When multiple stimuli are presented sequentially versus simultaneously, error variance is reduced. When a target is validly cued, precision is increased. What if they are manipulated together? We combined memory and attention manipulations in an orientation judgement task to answer this question. Two circular gratings were presented sequentially or simultaneously. On some trials a brief luminance cue preceded the stimuli. Participants were cued to report the orientation of one of the two gratings by rotating a response grating. We replicated the finding that error variance is reduced on sequential trials. Critically, we found interacting effects of memory and attention. Valid cueing reduced the median, absolute error only when two stimuli appeared together and improved it to the level of performance on uncued sequential trials, whereas invalid cueing always increased error. This effect was not mediated by cue predictiveness; however, predictive cues reduced the standard deviation of the error distribution, whereas nonpredictive cues reduced “guessing”. Our results suggest that, when the demand on memory is greater than a single stimulus, attention is a bottom-up process that prioritizes stimuli for consolidation. Thus attention and memory are synergistic.     

当事人眼里的工作同盟：质的分析

为了解中国当事人如何看待咨询中的工作同盟, 对工作同盟做初步的本土概念化, 采用协商一致的质的研究方法对来自1所大学心理咨询中心的20名当事人的访谈结果进行了分析。结果发现, 与工作同盟相关的域有6个, 分别是情感联结、任务、投入、合作模式、发展变化、影响因素。前三个域可以看作是工作同盟的构成要素, 而后三个域则是对其外部特征的描述。对每个域的含义及其与现有理论和研究的关系进行了讨论。     

A secondary task is not always costly: Context‐based guidance of visual search survives interference from a demanding working memory task

Repeatedly encountering a visual search display with the target located at a fixed position relative to the distractors facilitates target detection, relative to novel displays – which is attributed to search guidance by (acquired) long‐term memory (LTM) of the distractor ‘context’ of the target. Previous research has shown that this ‘contextual cueing’ effect is severely impeded during learning when participants have to perform a demanding spatial working memory (WM) task concurrently with the search task, though it does become manifest when the WM task is removed. This has led to the proposal that search guidance by LT context memories critically depends on spatial WM to become ‘expressed’ in behaviour. On this background, this study, of two experiments, asked: (1) Would contextual cueing eventually emerge under dual‐task learning conditions if the practice on the task(s) is extended beyond the short training implemented in previous studies? and given sufficient practice, (2) Would performing the search under dual‐task conditions actually lead to an increased cueing effect compared to performing the visual search task alone? The answer is affirmative to both questions. In particular, Experiment 1 showed that a robust contextual cueing effect emerges within 360–720 dual‐task trials as compared to some 240 single‐task trials. Further, Experiment 2 showed that when dual‐ and single‐task conditions are performed in alternating trials blocks, the cueing effect for the very same set of repeated displays is significantly larger in dual‐task blocks than in single‐task blocks. This pattern of effects suggests that dual‐task practice eventually leads to direct, or ‘automatic’, guidance of visual search by learnt spatial LTM representations, bypassing WM processes. These processes are normally engaged in single‐task performance might actually interfere with direct LTM‐based search guidance.
