Does worry affect adjustment to bereavement? A longitudinal investigation

Background and objectives: Repetitive thought is a trans-diagnostic risk-factor for development of psychopathology. Research on repetitive thought in bereaved individuals has focused primarily on clarifying the role of rumination, repetitive thinking about past negative events and/or negative emotions. While detrimental effects of rumination have been demonstrated following bereavement, surprisingly few studies have aimed to clarify the role of worry, repetitive thinking about potential future negative events, in adjustment to loss. This study sought to fill this gap in knowledge. Methods/Design: One hundred eighty-three bereaved individuals (85.3% women) filled out questionnaires on sociodemographic and loss-related characteristics, worry, and symptom measures of depression, anxiety, and prolonged grief. After six months, 155 participants completed worry and symptom measures again. Using multiple regression analyses, concurrent and longitudinal associations between loss-related variables, worry, and symptoms of psychopathology were examined. Results: Main results were that worry was strongly positively associated with symptoms of anxiety, depression and prolonged grief concurrently and also predicted higher levels of anxiety, depression and prolonged grief longitudinally. Conclusions: Findings suggest that worry influences adjustment to bereavement negatively and may be a potential target in grief therapy, especially when aiming to reduce anxiety.     

Are the literacy difficulties that characterize developmental dyslexia associated with a failure to integrate letters and speech sounds?

The ‘automatic letter‐sound integration hypothesis’ (Blomert, 2011 ) proposes that dyslexia results from a failure to fully integrate letters and speech sounds into automated audio‐visual objects. We tested this hypothesis in a sample of English‐speaking children with dyslexic difficulties (N = 13) and samples of chronological‐age‐matched (CA; N = 17) and reading‐age‐matched controls (RA; N = 17) aged 7–13 years. Each child took part in two priming experiments in which speech sounds were preceded by congruent visual letters (congruent condition) or Greek letters (baseline). In a behavioural experiment, responses to speech sounds in the two conditions were compared using reaction times. These data revealed faster reaction times in the congruent condition in all three groups. In a second electrophysiological experiment, responses to speech sounds in the two conditions were compared using event‐related potentials (ERPs). These data revealed a significant effect of congruency on (1) the P1 ERP over left frontal electrodes in the CA group and over fronto‐central electrodes in the dyslexic group and (2) the P2 ERP in the dyslexic and RA control groups. These findings suggest that our sample of English‐speaking children with dyslexic difficulties demonstrate a degree of letter‐sound integration that is appropriate for their reading level, which challenges the letter‐sound integration hypothesis.     

Illusions of Parental Control: Parenting and Smoking Onset in Dutch and Swedish Adolescents1

Parental control is assumed to be associated with smoking onset: Parents who exert control on their children and monitor their children's behavior are less likely to have children who start to smoke. However, the empirical evidence for this assumption is mostly from cross‐sectional studies. The present research examined the prospective associations between parental control and smoking onset among Dutch and Swedish adolescents and their parents. Findings revealed nonsignificant links between general parental control and smoking onset in both samples, and no link between smoking‐specific parental control and smoking onset in the Dutch sample, thereby questioning the assumption that parental control prevents adolescent smoking onset.     

When political expertise moderates the impact of scandals on young adults' judgments of politicians

This short note investigated how expertise in a political scandal moderates whether the activation of this scandal produces assimilation in the evaluation of politicians in general and contrast in the evaluation of specific politicians. It was hypothesized that participants with a rich knowledge about the scandal would display the assimilation and contrast effects whereas those with a poorer knowledge would not. Results tended to support this prediction, suggesting that the impact on judgment of a specific context depends on the amount of knowledge participants possess about this context.

Évaluation de l'efficacité d'un entraînement mnésique chez des personnes très âgées dépressives institutionnalisées

The focus of this work is to study the influence of “memory's training” on a group of 27 depressed elderly residents (age's mean = 84.77; GDS's mean = 17.7) and 28 non-depressed elderly residents (age's mean = 84.96; GDS's mean = 3.5) with self-reported memory loss. The training's task was a free recall using mmemonic method of Loci with each person. Results showed that depressed residents increase their performances during the training's sessions like non-depressed residents but not to the post-test. Consequently, the memory complaint is an indicator to propose to elderly person memory's training if the prevalence of depression is establish, so it is to be hoped that further or additional interventions be proposed.     

中国的安乐死观念与卫生保健

把在荷兰福利体制下狭义的安乐死概念移植到中国是不适当的.对于临终病人医疗上的缺陷不能用他们临终时的体面、尊严这一标准来衡量.这一问题的解决不是迅速地结束生命,而是要通过中国卫生医疗决策中的分配公正来提高生命的质量,需要建立一个跨国框架来讨论安乐死的特性与共性.     

发展性阅读障碍的脑区连接异常

过去几十年中, 研究者基于脑区功能定位的思想对发展性阅读障碍的神经机制进行了大量的研究, 揭示出阅读障碍者在特定脑区的异常。近些年, 考虑到阅读加工过程的复杂性以及需要多脑区协同参与的特点, 越来越多的研究者从脑区连接的角度探讨阅读障碍的神经机制。结果发现阅读障碍者在阅读相关脑区间的白质结构连接和功能连接上均表现出异常, 这说明阅读技能受损和脑区连接异常之间存在着密切的联系。未来的研究还需进一步探讨脑区连接异常和特定脑区异常之间的关系, 以及结合基因、脑、行为和环境等多个因素探寻阅读障碍的发生机制。     

Pre‐frontal‐insular‐cerebellar modifications correlate with disgust feeling blunting after subthalamic stimulation: A positron emission tomography study in Parkinson's disease

Subthalamic nucleus (STN) deep brain stimulation (DBS) has recently advanced our understanding of the major role played by this basal ganglion in human emotion. Research indicates that STN DBS can induce modifications in all components of emotion, and neuroimaging studies have shown that the metabolic modifications correlated with these emotional disturbances following surgery are both task‐ and sensory input‐dependent. Nevertheless, to date, these modifications have not been confirmed for all emotional components, notably subjective emotional experience, or feelings. To identify the neural network underlying the modification of feelings following STN DBS, we assessed 16 patients with Parkinson's disease before and after surgery, using both subjective assessments of emotional experience and ¹⁸[F]fluorodeoxyglucose positron emission tomography (¹⁸FDG‐PET). The patients viewed six film excerpts intended to elicit happy, angry, fearful, sad, disgusted, and neutral feelings, and they self‐rated the intensity of these feelings. After DBS, there was a significant reduction in the intensity of the disgust feeling. Correlations were observed between decreased disgust experience and cerebral glucose metabolism (FDG uptake) in the bilateral pre‐frontal cortices (orbitofrontal, dorsolateral, and inferior frontal gyri), bilateral insula, and right cerebellum. We suggest that the STN contributes to the synchronization process underlying the emergence of feelings.     

Patients with bipolar disorder show a selective deficit in the episodic simulation of future events

A substantial body of evidence suggests that autobiographical recollection and simulation of future happenings activate a shared neural network. Many of the neural regions implicated in this network are affected in patients with bipolar disorder (BD), showing altered metabolic functioning and/or structural volume abnormalities. Studies of autobiographical recall in BD reveal overgeneralization, where autobiographical memory comprises primarily factual or repeated information as opposed to details specific in time and in place and definitive of re-experiencing. To date, no study has examined whether these deficits extend to future event simulation. We examined the ability of patients with BD and controls to imagine positive, negative and neutral future events using a modified version of the Autobiographical Interview (Levine, Svoboda, Hay, Winocur, & Moscovitch, 2002) that allowed for separation of episodic and non-episodic details. Patients were selectively impaired in imagining future positive, negative, and neutral episodic details; simulation of non-episodic details was equivalent across groups.
