边缘刺激条件下错误记忆的实验研究

随着研究的深入,研究者越来越关注错误记忆中的无意识成分。本研究试图采用边缘刺激这一方法研究错误记忆中的意识-无意识机制。结果发现,边缘刺激会引发错误记忆,但它不受刺激知觉时的意识-无意识水平限制;而且这种错误记忆-经发生便很稳定,不随测量时间间隔的延长而改变。另外。研究还发现材料这一因素往往会和其他因素交融在一起共同作用于错误记忆。     

Gender Differences in Vivid Memories

Seventy-four adults (50% women) individually completed a memory questionnaire. They were given a definition of a flashbulb memory and were asked to describe their 3 most vivid memories. In addition, participants rated the described events for various characteristics (e.g., emotional load and personal importance) and provided their best estimate of the date of each event. Effects of gender on the content of vivid memories, their form, and their distribution were found. The influence of identity on the recollection of personal experiences and gender differences in the development of autobiographical memory are discussed.     

Returning to the present moment: Thinking about one’s childhood increases focus on the hedonistic present

Children seem to live more in the present moment than adults. But is it possible to make the present time perspective more available among adults? Four experiments demonstrated that activating childhood selves can lead adults to be more embedded in the hedonistic present. Studies 1 and 2 showed that recalling memories from childhood, either in an open-ended or a structured form, increased participants’ focus on the hedonistic present. Study 3 showed that this effect also occurred after an implicit childhood manipulation. Study 4 revealed that taking the perspective of a child significantly increased orientation to the hedonistic present, compared to taking the perspective of an adult. The effects of activation of childhood selves were not mediated by mood, nostalgia, impatience, concentration, difficulty of the task, enjoyment connected with the task, or involvement in the task. Evaluation of one’s childhood and tendency to relive childhood memories did not affect the results.     

When Conflict Traumas Fragment: Investigating the Sociopsychological Roots of Turkey’s Intractable Conflict

This article investigates the historical processes contributing towards the specific development of Turkey after the 1920s that in turn established the main contours of Turkey's conflict with the Partiya Karkerên Kurdistanê (PKK). It first argues that the traumatic conflict memories of the Turkish leadership (1918–35) influenced its individual‐level patterns of actions. These memories were used by the leadership to consolidate its imagined national agency in Turkey. The leadership perceived the traditional‐conservative groups as ontological insecurity sources, jeopardizing this agency. It second claims that Turkey's military apparatus is designed to silence these ontological insecurity sources. Finally, it claims these developments informed the ways in which the PKK's narratives of rebellion were constructed. Empirically, it problematizes the impact of the Ottoman Empire's collapse on the Turkish elites. Then, through a discourse analysis of elites' speeches and legal documents, it traces their anxieties to the Ottoman Empire's traumatic end. This article contributes to the trauma literature on ontological security and the emotions literature in International Relations in two ways. It first explores the particular national context in which traumatic memories are shaped and in turn articulated through emotional performances. Secondly, it shows the interplay between sociopsychological processes of security and agency making.     

非自主闯入焦虑发生的机制：阈下启动效应的实验研究

本研究采用阈下情感启动范式, 研究威胁信息启动效应及其特质焦虑的调节作用,旨在揭示焦虑非自主闯入性特点形成的机制。实验在随机的三种条件下（阈上/阈下/基线）给38名被试呈现两种目标词（威胁词和中性词）,其中基线条件不呈现目标词;之后要求被试在回避目标词的条件下完成组词任务,结果：（1）无论是中性词还是威胁词,被试阈下条件下目标词的击中率显著高于基线条件;（2）特质焦虑对阈下启动效应起着调节作用：高焦虑组被试威胁词的启动效应显著高于中性词,低焦虑组被试中性词的启动效应显著高于威胁词。结论：阈下启动效应显著,高特质焦虑组个体对威胁信息的无意识加工会增强对威胁信息的意识加工,产生闯入性想法,导致焦虑非自主闯入性的特点。     

Pre-stressor cognitive control is related to intrusive cognition of a stressful film

It has been suggested that relatively weak cognitive control existing prior to a stressful event may be associated with intrusive memories of that stressor afterwards. We explored this in two analog studies employing unselected participants who saw an emotional film fragment and completed behavioral (i.e., color-naming interference [CNI]) and self-report indices of intrusions. Prior to film presentation, several cognitive control tests were administered. Study 1 showed that better updating/monitoring was linked to less CNI from negative film-related words. However, better updating/monitoring was associated with more diary reports of intrusive memories. Study 2 showed that a better resistance to pro-active interference (PI) predicted less self-reported film-related intrusive cognition after 24h. However, after this delay, both self-reported intrusions and CNI were not related to updating/monitoring. Taken together, the results suggest that a specific pre-existing cognitive control function (i.e., resistance to PI) may be involved in the regulation of post-stressor intrusive memory phenomena.     

Trauma-related and neutral false memories in war-induced Posttraumatic Stress Disorder

Recent models of cognition in Posttraumatic Stress Disorder (PTSD) predict that trauma-related, but not neutral, processing should be differentially affected in these patients, compared to trauma-exposed controls. This study compared a group of 50 patients with PTSD related to the war in Bosnia and a group of 50 controls without PTSD but exposed to trauma from the war, using the DRM method to induce false memories for war-related and neutral critical lures. While the groups were equally susceptible to neutral critical lures, the PTSD group mistakenly recalled more war-related lures. Both false and correct recall were related more to depression than to self-rated trauma. Implications for accounts of false memories in terms of source-monitoring are discussed.     

Investigation of the indulgence cycles hypothesis of suppression on experimentally induced visual intrusions in dysphoria

Within the thought control literature, Wegner [(1989). White bears and other unwanted thoughts: Suppression, obsession, and the psychology of mental control. New York, NY, USA: Penguin Press.] referred to the combined initial suppression and expression phases of thought control as an indulgence cycle which results in the rebound effect typically observed in suppression studies. According to Ironic Process Theory [Wegner, (1994). Ironic processes of mental control. Psychological Review, 101, 34-52.], this rebound leads to further attempts to suppress that are difficult due to the target thought's hyperaccessibility, resulting in a secondary rebound effect owing to a positive feedback system of indulgence cycles. The current study investigated (i) the effects of repeated suppression and opportunities for expression by using a method to index the frequency, duration, and associated levels of distress of an experimentally induced visual intrusion, and (ii) whether any observed effects were differentially linked to depressive symptomatology in an analogue sample of low and high dysphoric participants. Results supported a secondary rebound effect in those participants most successful at suppressing target intrusions. The findings offer an important extension to the emerging literature on the management of intrusive memories in depression.     

Healing Together

As part of the World Council of Churches’ pilgrimage of justice and peace, the Just Community of Wo/Men organized the “Walking Her-Story” activity as a gender response. These have remained pilgrim team visits that focus on listening to the stories of wo/men young and old and particularly addressing gender injustice specifically as expressed in sexual and gender-based violence. This article focuses on the process triggered by such stories in Burundi, Democratic Republic of the Congo, Nigeria, and South Sudan that became the midwife that gave birth to Healing Together – an ecumenical resource for faith- and community-based counselling of those psychosocially wounded by injustice and violence. Rooted in the understanding of mission as healing and wholeness, the stories listened to became a cry for healing and wholeness. The process and product benefited from the richness of my being an ethicist of care nurtured by my ubuntu (communitarian) ethical background, trained in Healing of Memories’ facilitation and as a student of Franklian logotherapy. I worked with survivors of injustice and violence, post-traumatic stress disorder healing facilitators, and church leaders through the council of churches in Nigeria, Sierra Leone, and South Sudan.     

Motor adaptation and manual transfer: Insight into the persistent nature of sensorimotor representations

It is well known that sensorimotor memories are built and updated through experience with objects. These representations are useful to anticipatory and feedforward control processes that preset grip and load forces during lifting. When individuals lift objects with qualities that are not congruent with their memory-derived expectations, feedback processes adjust motor plans to achieve successful lifts and contribute to the updating of the stored representations. The two experiments presented examine motor adaptation to an illusory size–weight lifting task, and the transfer of this motor adaptation to the unexposed hand. In Experiment 1, performers acquired motor adaptation with their right hand and transfer was measured on their left hand. In Experiment 2, adaptation was acquired with the left hand and transfer was measured on the right hand. In order to investigate the persistence of sensorimotor memories, these experiments measure adaptation, retention, and transfer after 15 min and 24 h delay periods. Both experiments confirm that experience with objects leads to adaptation of force scaling processes, that these adaptations transcend effector and are persistent. The results are discussed in terms favouring interpretations that describe motor adaptations to illusion as being centrally available.
