表象预期调控生物运动性别信息的识别

生物运动系在运动的生物体身的关键节点安置12～15个光点的运动痕迹形成的动画。研究表明光点生物运动包含了丰富的社会性信息,其社会性信息的识别涉及多个心理活动过程,其中大脑自上而下的知觉调控过程发挥重要作用。本研究通过两个实验探讨了表象预期在大脑自上而下调控光点生物运动性别信息识别的作用。结果发现：（1）表象预期能够加快男性生物运动的性别识别速度;想象中性形象被试倾向于将性别中立的生物运动识别为中性,而较少为男性或者女性。（2）表象预期条件和无表象预期条件下性别中立的光点生物运动性别类型识别都表现出“男性偏差”现象。（3）反应类型能够影响生物运动的性别识别。本研究有利于揭示大脑自上而下调控光点生物运动性别信息识别的心理机制。     

若干实验室指标对糖尿病神经病变的预测意义

近年来,人们发现了一些实验室指标对糖尿病神经病变有一定预测意义,包括糖化血红蛋白、维生素B12、甲基丙二酸、全反钴胺素、同型半胱氨酸、氧化型低密度脂蛋白、甘油三酯、超敏C反应蛋白、肿瘤坏死因子α(TNF-α)、可溶性肿瘤坏死因子受体1、可溶性肿瘤坏死因子受体2等。这些指标对糖尿病神经病变的早期防治提供了帮助。     

致病性微生物耐药性严重化问题的思辨

致病性微生物耐药性严重化是一道世界性医学难题。微生物使出种种耐药的"招术",不只是其对药物作用的反应,更应看到是耐药内外因相互作用的结果,是其生物本性之使然。微生物的基本特性使其具备这种"能耐"。这些耐药性应存在一定的"原动机制",可以认定微生物的耐药性必然永远存在。人类社会必须构建长效的、与时俱进的防、抗致病微生物耐药性的卫生工作机制。

The neural correlates of orienting to walking direction in 6‐month‐old infants: An ERP study

The ability to detect social signals represents a first step to enter our social world. Behavioral evidence has demonstrated that 6‐month‐old infants are able to orient their attention toward the position indicated by walking direction, showing faster orienting responses toward stimuli cued by the direction of motion than toward uncued stimuli. The present study investigated the neural mechanisms underpinning this attentional priming effect by using a spatial cueing paradigm and recording EEG (Geodesic System 128 channels) from 6‐month‐old infants. Infants were presented with a central point‐light walker followed by a single peripheral target. The target appeared randomly at a position either congruent or incongruent with the walking direction of the cue. We examined infants' target‐locked event‐related potential (ERP) responses and we used cortical source analysis to explore which brain regions gave rise to the ERP responses. The P1 component and saccade latencies toward the peripheral target were modulated by the congruency between the walking direction of the cue and the position of the target. Infants' saccade latencies were faster in response to targets appearing at congruent spatial locations. The P1 component was larger in response to congruent than to incongruent targets and a similar congruency effect was found with cortical source analysis in the parahippocampal gyrus and the anterior fusiform gyrus. Overall, these findings suggest that a type of biological motion like the one of a vertebrate walking on the legs can trigger covert orienting of attention in 6‐month‐old infants, enabling enhancement of neural activity related to visual processing of potentially relevant information as well as a facilitation of oculomotor responses to stimuli appearing at the attended location.     

“Putin,You Suck”: Affective Sticking Points in the Czech Narrative on “Russian Hybrid Warfare”

Using the case of the Czech narrative on “Russian hybrid warfare” (RHW), this article contributes to the broader question of why narratives succeed. Building on Lacanian psychoanalysis, narrative scholarship, and affect/emotions research in International Relations, we suggest that narrative success is facilitated also by two interrelated factors: embedding in broader cultural contexts and the ability to incorporate and reproduce collectively circulating affects. We develop a methodological framework for encircling unobservable affects within discourse via “sticking points”—linguistic phenomena infused with affective investment. We outline three categories of sticking points—valued signifiers, fantasies, and biographical narratives. Utilizing the approach in our case study, we focus on a narrative based around the notion that Russia waged a “hybrid war” against “the West” and that this should be faced with quasi‐military measures, which was successful in changing the language of Czech national security. We show that this narrative incorporated a range of sticking points, which contributed to its relative success. It utilized valued signifiers, such as “the West,” “the Kremlin,” “agents,” and “occupation,” weaved them together into a fantasy of a threat to the nation's “Western” identity, and intertwined this with the biographical narratives of history as a lens for world politics and East/West geopolitics.     

Rethinking the Human Being in Light of Evolutionary Biology

Abstract : For the sake of its own enrichment and relevance, Christian anthropology today must be informed by what we are learning from the biosciences, including the theory of biological evolution. The two quite different paradigms of theology and biology should be seen as complementary to each other, with theology recognizing the biological foundation of human nature. This necessitates a repudiation of the traditional body/soul dualism and re‐conceptualizing the concept of soul as a metaphorical expression rather than a spiritual entity. It affirms the spiritual dimension of human life that relates us to God and neighbor. Biblical scholarship affirms this psychosomatic, holistic view of the human being.     

Pluralism and Ambivalence in the Evolution of Morality

Much good work has been done on the evolution of human morality by focusing on how “selfish genes” can give rise to altruistic human beings. A richer research program is needed, however, to take into account the ambivalence of naturally evolved biopsychological motivators and the historical pluralism of human morality in religious systems. Such a program is described here. A first step is to distinguish the ultimate cause of natural selection from proximate causes that are the results of natural selection. Next, some proximate causes are suggested as possible conditions of biological and emotional valuing as well as of customary social morality and individual rational ethical thought. Finally, different moral perspectives of Confucianism, Hinduism, Buddhism, and Christianity are briefly presented in order to illustrate how one might inquire about the selection of a variety of biopsychological and cultural proximate causes that enable the evolution of a plurality of religious moral systems.

What Does It Mean to Be Human? A Personal and Catholic Perspective

A philosopher-poet-theologian ponders the implications of the multimillion-year biogenetic process that produced Homo sapiens and is beginning to reveal itself ever more clearly as evolution of the mind and consciousness. As meaning trappers and makers, called to actualize the divine image imprinted upon us, we are now facing biological and cultural evolution with deliberate human input as well as the evolution of evolution. As communicating animals that are becoming ever more aware of our adaptive behavior, we have the potential of affecting our own destiny by listening to the spirit within and nurturing the genes and memes that give rise to physical, intellectual, creative, and moral excellence. In the matrix of cyberspace we have the opportunity to heal the two-culture split, to reinvent ourselves, to incubate/weave the emergent religions of the future, and to create our multiple "Ways" appropriate to the dawning Age of Global Dialogue.
