Thought suppression failures in combat PTSD: A cognitive load hypothesis

The present study investigated the relation between thought suppression of emotionally neutral content [i.e., Wegner's (1994) “white bear”], incidental traumatic thought intrusion, and skin conductance responses in combat-related Posttraumatic Stress Disorder (PTSD). Participants included service members who either: a) had PTSD following an Operation Iraqi Freedom deployment; b) were free of psychiatric diagnosis following deployment (Combat Equivalent), or c) were pre-deployed and without psychiatric diagnosis (Pre-Deployed). PTSD Service Members reported the greatest intrusion of combat thoughts during the suppression task and demonstrated a post-suppression rebound effect with a neutral thought. Non-specific skin conductance responses indicated that the suppression task was related to similar levels of increased sympathetic activity for both the PTSD and Pre-Deployed groups, whereas the Combat Equivalent group showed no increased activation during thought suppression. Intrusive traumatic thoughts combined with failures in neutral thought suppression may be a consequence of increased cognitive load in PTSD.     

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.     

自传体广告优势效应的实验研究

自传体广告能够唤起消费者对产品或品牌的某些以往记忆,它会影响人们对广告信息的加工方式,同时更为重要的是它能够改变人们的认知。在营销实战和研究中,都备受关注。本研究试图通过两个实验探讨它的内在机制,以及与事实性广告相比,在感知觉、情绪情感、认知改变等方面的优势。结果发现自传体广告确实在感知觉、情绪情感、认知改变等方面具有优势效应。此外还发现了自传体广告的特异性。     

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.     

Intrusive parenting,teacher sensitivity,and negative emotionality on the development of emotion regulation in early head start toddlers

Toddler emotion regulation develops within the context of relationships but is also influenced by toddlers’ individual characteristics. Drawing on transactional and differential susceptibility frameworks, this study examined direct and interactive associations of intrusive parenting, teacher sensitivity, and negative emotionality on toddler emotion regulation development in a sample of Early Head Start families utilizing center-based child care. Latent growth models indicated that, after controlling for a series of family and child care covariates, intrusive parenting at 14 months had diminishing effects on trajectories of emotion regulation across toddlerhood (14 to 36 months), whereas teacher sensitivity in child care was promotive for emotion regulation growth. Toddlers with high negative emotionality were not more susceptible to the effects of intrusive parenting or teacher sensitivity on emotion regulation development, however, results suggested emerging evidence for individual differences in the protective nature of teacher sensitivity in the context of high intrusion at home. Results are discussed in terms of their implications for informing parents and early care and education providers in nurturing relationships with the children who may be the most challenging to care for but may stand to make the greatest gains in emotion regulation development in quality caregiving settings.     

Ageing and thought suppression performance: Its relationship with working memory capacity,habitual thought suppression and mindfulness

A study investigated how the ability to suppress thoughts in the laboratory was affected by type of thought suppressed (positive, negative, neutral), participants’ age and working memory capacity (WMC). Linked variables (Use of thought suppression, social desirability, and mindfulness) were measured to assess whether they modified susceptibility to thought intrusion.Younger, middle aged and older adults suppressed three different valenced thoughts in a counterbalanced order for 5-min per thought. Participants then completed a WMC task and questionnaire measures of the linked variables.Valence had no effect on intrusions. WMC was positively related to intrusions; higher WMC corresponded to greater intrusions. Age was negatively related to intrusions; with increasing age intrusions decreased. Hierarchical regression showed only age and backward digit span (WMC) significantly predicted intrusions. The relationship between WMC and intrusions was not moderated by age. WMC and age both independently predict level of intrusion, and no synergistic effect was found.
