Dialectical Behavior Therapy of Anorexia and Bulimia Nervosa Among Adolescents: A Case Series

The aim of this study was to describe a case series of adolescents (mean age = 16.5 years, SD = 1.0) with anorexia nervosa (AN) and bulimia nervosa (BN) who received dialectical behavior therapy (DBT). Twelve outpatients with AN and BN took part in 25 weeks of twice weekly therapy consisting of individual therapy and a skills training group. Family members were involved in the treatment. The patients were compared pre- and posttreatment on behavioral symptoms of AN and BN and symptoms of general psychopathology using standardized instruments (Structured Inventory for Anorectic and Bulimic Syndromes, Eating Disorder Inventory-2, The Symptom Checklist-90-Revised). Posttreatment, significant improvements in behavioral symptoms of eating disorder and symptoms of psychopathology were identified. The application of DBT adapted for the treatment of AN and BN among adolescents was associated with a decrease in behavioral symptoms of eating disorders and symptoms of general psychopathology. However, randomized controlled studies are required to prove the efficacy of this approach.     

Modeling spatial and temporal aspects of visual backward masking

Visual backward masking is a versatile tool for understanding principles and limitations of visual information processing in the human brain. However, the mechanisms underlying masking are still poorly understood. In the current contribution, the authors show that a structurally simple mathematical model can explain many spatial and temporal effects in visual masking, such as spatial layout effects on pattern masking and B-type masking. Specifically, the authors show that lateral excitation and inhibition on different length scales, in combination with the typical time scales, are capable of producing a rich, dynamic behavior that explains this multitude of masking phenomena in a single, biophysically motivated model.     

Die Wirkung von traumatischem Stress auf biopsychische Selbstorganisationsprozesse

Social frameworks have influenced the understanding of trauma-reactive psychic disorders during the course of the past two centuries.The 20th century has further shaped this understanding by the various concepts established by the different therapeutic schools.The incorporation of scientific results, as well as the theory of complex dynamic systems particularly that of synergetics supply now abundant impulses stimulating the discussion of posttraumatic stress disorders on a psychodynamic, neurophysiological, and systemspecific basis, thereby leaving those schools behind.Comparing synergetic models with the current state of neuroscientific research of post traumatic stress disease (PTSD) gives surprising insights of the dynamics of this disorder,and the resulting therapeutic principles.Specific therapeutic approaches, with the two phases of stabilisation and of trauma processing can be derived from such functional principles of neuronal networks.     

To look or not to look: an eye movement study of hypervigilance during change detection in high and low spider fearful students

Previous eye movement studies of attentional bias in spider fear reported inconsistent results with respect to early attentional capture, suggesting that overt attentional capture only reliably occurs under specific circumstances. In addition, none of these studies explored covert attention. The present study examined attentional bias in spider phobia using a change detection paradigm that was expected to provide good conditions for documenting attentional capture. In contrast to our expectations, eye movement data showed that all participants' first fixations were fastest on general negative targets, whereas participants' first fixations on spider targets were slower in the spider fearful than in the nonfearful group. In addition, spider fearful participants made more nontarget fixations before fixating on a spider target than did nonfearful participants. Thus, we found that participants' overt attention was more quickly focused on general negative targets, whereas covert attentional processes enabled initial avoidance of fear-relevant (i.e. spider) stimuli. The present findings have important implications for research on attention and fear as they indicate that fearful individuals are not characterized by static attentional orienting toward threat but, under certain conditions, may avert attention from threat automatically.     

“时间窗”—— 认知加工的后勤基础

时间加工是认知加工的内在属性。因此, 理解发生在知觉或更广泛的认知过程中的时间加工极为重要。为了应对中枢信息加工所面临的外部挑战, 大脑显然已形成了一些用于整合信息的特殊时间窗。已经发现, 其中一个时间窗介于数十毫秒的范围内, 它用于为意识活动产生必要的建构单元。来自反应时、时序阈限以及神经元结构振荡反应的研究为该时间窗的存在提供了实证证据。另一个时间窗的作用范围是2~3秒, 它用于产生“主观现在感”或作为使知觉体的标识保持不变的时间整合区间。支持该窗口存在的实验证据来自时距再现、两可图形、感觉运动同步以及神经生理学研究。还有一种时间窗以昼夜节律的形式存在。所有的心理和生理功能似乎都有着24小时的周期性变化。时间窗的紊乱会以神经或精神疾病的形式表现出来, 这恰恰表明了在基础研究之外对时间加工进行研究的重要性。     

Innovative Ideas on How Work-Family Research Can Have More Impact

The commentaries on our focal article agreed with its main premise that work-family research should follow new strategies to improve its practical impact, and made suggestions clustering into three main themes. The first theme built on our suggestion to improve the research focus, terminology, and framing of work-family research. These essays offered additional ideas such as decoupling work-family from work-life research, and examining contextual factors more deeply. The second theme focused on how to better apply the findings from work family research. These commentaries provided social change approaches for making work-family issues more central to key stakeholders and to organizations. The third theme focused on broadening our scope to the societal level. These editorials advocated tactics supporting the development of basic rights of work-life balance within and across nations.     

Loneliness within a nomological net: An evolutionary perspective

Loneliness is characterized by feelings of social pain and isolation and has both heritable and unshared environmental underpinnings. An evolutionary theory of loneliness is outlined, and four studies replicate and extend prior research on the characteristics of lonely individuals. Studies 1 and 2 indicate that loneliness and depressed affect are related but separable constructs. Study 3 confirms that lonely, relative to nonlonely, young adults are higher in anxiety, anger, negative mood, and fear of negative evaluation, and lower in optimism, social skills, social support, positive mood, surgency, emotional stability, conscientiousness, agreeableness, shyness, and sociability. The set of six personality factors associated with loneliness (surgency, emotional stability, agreeableness, conscientiousness, shyness, and sociability) do not explain the associations between loneliness and negative mood, anxiety, anger, optimism (pessimism), self-esteem, and social support, as each association remained statistically significant even after statistically controlling for these personality factors. Study 4 used hypnosis to experimentally manipulate loneliness to determine whether there were associated changes in the participants’ personality and socioemotional characteristics. Results confirmed that loneliness can influence the participants’ personality ratings and socioemotional states.     

康德历史哲学的基础

作者认为,康德历史形而上学的意义不次于《纯粹理性批判》在其自身领域的重要性,它将哲学问题由存在领域转向义务领域。普遍世界历史观采用的是先验方法,与目的论联系在一起,体现出大自然的计划。如果说康德伦理学追求个体的自由及其道德独立性,那么其历史哲学则强调人类只有通过社会这个媒介,才能实现其真正的道德任务。人类自身的二重性构成康德历史哲学的本质,也是历史与社会发展的动力,由此决定了社会政治的真正任务,由此方显启蒙运动的真正意义。
