人以天地之气生:气象对人类心理与行为的影响

从情绪波动到文明兴衰,研究者愈来愈意识到大气现象对人类的重要影响。气象心理学涵盖天气和气候这两大类大气现象作用于人类个体和群体的心理与行为乃至文化特征的各种研究。在个体心理层面,温度、湿度、日照等气象因素会影响个体情绪、工作记忆和认知能力。在个体行为层面,人际亲和行为和反社会行为也会被天气左右。在群体和文化层面,从长程上考察,气温和降水量与多尺度人类群体冲突爆发密切相关;气候冷暖和资源多寡也会共同形塑当地族群的文化心理行为特征。人类世界始终嵌入于天气和气候等宏观生态环境中并受其影响,气象心理学应当在心理学研究体系中占有一席之地。     

Stimulated release of tissue plasminogen activator from artery wall sympathetic nerves: implications for stress-associated wall damage

Recurrent stress is clinically associated with early onset hypertension and coronary artery disease. A mechanism linking emotion to pathogenic remodeling of the artery wall has not been identified. Stress stimulates acute regulated release of tissue plasminogen activator (t-PA) into the circulation, which is presently attributed to the vascular endothelium. Sympathetic neurons also synthesize t-PA and axonally transport it to the arterial smooth muscle. Unlike release by the endothelium, a stress-stimulated sympathetic discharge would potentially accelerate degradation of the wall matrix by plasmin. To assess whether sympathetic axons are the principal source of acute stress-induced arterial release of t-PA, we compared the output from small densely innervated and large sparsely innervated isolated artery segments before and after sympathetic stimulation, and after ablations. Following phenylephrine infusion densely-innervated microvessels in uveal eyecups were released over 60-fold greater amounts of active t-PA per milligram than the sparsely innervated aorta; and ten-fold more than carotid artery segments. Mesenteric artery release was 4.8-fold greater than release by the carotid artery. In vivo, uveal release of t-PA increased more than three-fold within one minute following superior cervical sympathetic ganglion electrical stimulation, and after phenylephrine, or nicotine infusions of the anterior chamber. Circulating levels of t-PA fell 70% following chemical sympathectomy. We propose that sympathetic nerves are the primary source of stress-induced release of t-PA into and from the densely innervated resistance arteries and arterioles, where dysregulated plasmin-induced proteolysis could damage the wall matrix.     

表演式学习──表演理论对“最近发展区”的发展

美国当代心理学家、剧作家、表演理论的创始人弗雷德·纽曼（FredNewman）及其同事致力于在实践中发展维果茨基的理论,从表演的维度探讨了zpd的概念,并以此为核心提出了表演式学习的概念,以区别于在当今社会大行其道的工具性学习,即以获取知识和技能为目的的学习。表演理论通过对工具性学习的消极影响的批判及对表演式学习的倡导,在人的教育和发展方面提出了独到见解。     

The Ambiguity of Kant's Concept of the Highest Good: Finding the Correct Interpretation

The aim of this paper is to resolve the tension between Kant's doctrine of the highest good and his entire philosophical system. The concept of the highest good is the first major ambiguity of the doctrine. There are three pairs of ambiguities: immanent‐transcendent; justice‐perfection; and individual‐community. They are able to form eight combinations. Corresponding to the various combinations and conceptions of the highest good, interpreters also conceive different reasons for the necessity of the doctrine as well as various conditions of its applicability. For example, some emphasize its religious dimension, whereas others understand it in the political sense. In this paper, I adopt a different approach in understanding the highest good's systematic meaning as the moral confirmation, and suggest that only a transcendent, perfect and communal concept of the highest good can provide the most consistent doctrine. Additionally, it explains the importance of the different branches (such as philosophies of religion and of politics) of Kant's system.     

A technique for simulating visual field losses in virtual environments to study human navigation

The following paper describes a new technique for simulating peripheral field losses in virtual environments to study the roles of the central and peripheral visual fields during navigation. Based on Geisler and Perry's (2002) gaze-contingent multiresolution display concept, the technique extends their methodology to work with three-dimensional images that are both transformed and rendered in real time by a computer graphics system. In order to assess the usefulness of this method for studying visual field losses, an experiment was run in which seven participants were required to walk to a target tree in a virtual forest as quickly and efficiently as possible while artificial head and eye-based delays were systematically introduced. Bilinear fits were applied to the mean trial times in order to assess at what delay lengths breaks in performance could be observed. Results suggest that breaks occur beyond the current delays inherent in the system. Increases in trial times across all delays tested were also observed when simulated peripheral field losses were applied compared to full FOV conditions. Possible applications and limitations of the system are discussed. The source code needed to program visual field losses can be found at lions.med.jhu.edu/archive/turanolab/Simulated_Visual_Field_Loss_Code.html.

霍妮神经症理论述评

依照神经症演进的心理历程为线索,从神经症的起因、人际策略、心理内防御策略、最终表现和治疗五个方面系统论述了霍妮的神经症理论,并在此基础上指出,霍妮的神经症理论是对弗洛依德思想的批判继承,其理论影响力、应用性正受到应有的关注。     

犹太科学运动的政治和民族动因

19世纪上半叶,在犹太学领域兴起的科学运动是在欧洲民族主义普遍发展、现代反犹主义加剧的情况下进行的,它的背后潜藏着深厚政治和民族动因。德意志民族主义一方面强化了反犹主义,使得犹太知识精英在文化界特别是大学面临困境,犹太人从痛苦的经历中感受了一种前所未有的民族存在意识。作为一种正面力量,德意志民族浪漫主义思潮也激发并强化了犹太民族自信心,它与启蒙时代的理性主义汇合,为科学犹太学提供了动力。因此,犹太科学运动可以被看作是犹太民族史上的一场文化复兴运动。
