论神经语言学的兴起与发展

神经语言学是一门新兴的医学与语言学的交叉边缘学科。简要论述了该学科的起源,研究范围,主要研究方法以及在我国的研究现状,还探讨了它与神经哲学的关系和它的哲学思考。因此,神经语言学体现了现代科学各学科门类交叉的必然趋势,是当代学术研究的前沿,具有广阔的发展前景。     

道德直觉加工机制的理论构想

认知和情绪因素在道德判断中的作用机制是社会认知神经科学研究中最具争议的热点问题之一。本文认为, 人类拥有一种普遍性的道德直觉, 它是一种可能同时包含道德知识和情绪情感的自动化加工系统, 决定人们对一个道德违反情境作出快速的判断。据此, 本文就如何深入揭示道德直觉的加工机制提出了研究构想, 研究将首先采用经颅磁刺激技术, 探索当认知功能受抑制后人们的道德加工的特点, 初步探索道德直觉存在的可能性; 然后采用事件相关电位技术, 从外显和内隐两个维度上探讨道德直觉的时程加工机制; 最后采用侧向化运动准备电位指标, 进一步探索道德直觉和基本厌恶情绪的分离。     

客体工作记忆任务中大脑皮层活动的记忆负荷效应

利用128导事件相关电位技术,采用延迟匹配任务的实验范式,测查了20名正常被试完成不同负荷客体任务时的皮层慢电位（slow cortical potentials,简称sp成分）,实验发现：背侧前额叶在刺激呈现后的700ms到1400ms出现记忆负荷效应,高负荷任务诱发的sp成分显著负于低负荷任务;低负荷任务诱发的sp成分在左前额区（500~1800ms）、左前额-中央区（700~1800ms）、左中央-顶叶区（1000~1400s和1800~4800ms）、右前额区（1800~4800ms）和右前额-中央区（1400~4800ms）显著负于高负荷任务,出现记忆负荷效应,但这种负荷效应在左右大脑半球所反映的心理意义可能不同     

Why Freud and Jung Can’t Speak: A Neurological Proposal

This article provides a modern neurological explanation for the theoretical differences in psychoanalytic concepts and techniques between Freud and Jung. Specifically, the article contrasts their analytic skills as arising in the left and right brain, respectively. Modern neurological techniques reveal unique brain functions that explain many of the visionary and so-called mystic phenomena discussed by Jung. Many of his psychoanalytic concepts can be traced to right brain function. Modern research and philosophic analyses also provide light on Freud’s research method and its limitations.Barbara Stevens Barnum, RN, PhD, FAAN, former editor of Nursing Leadership Forum and Nursing & Health Care, is presently a writer/consultant. Before retiring, her positions at Columbia University included holding the directorship, Division of Health Services, Sciences and Education at Teachers College, where she also held the Stewart Chair in the Department of Nursing Education. Dr. Barnum has written in areas of nursing management, theory, education, and aspects of spirtuality/holistic nursing. Her books include: Nursing theory: Analysis, application, evaluation, Spirituality in nursing: From traditional to New Age, and The New Healers: Minds and Hands in Complementary Medicine.     

QUANTUM INTERACTIVE DUALISM: AN ALTERNATIVE TO MATERIALISM

Abstract. René Descartes proposed an interactive dualism that posits an interaction between the mind of a human being and some of the matter in his or her brain. However, the classical physical theories that reigned during the eighteenth and nineteenth centuries are based exclusively on the material/physical part of Descartes' ontology, and they purport to give, in principle, a completely deterministic account of the physically described properties of nature, expressed exclusively in terms of these physically described properties themselves. Orthodox contemporary physical theory violates this condition in two separate ways. First, it injects random elements into the dynamics. Second, it requires psychophysical events, called Process 1 interventions by John von Neumann. Neither the content nor the timing of these events is determined, even statistically, by any known law. Orthodox quantum mechanics considers these events to be instigated by choices made by conscious agents. This quantum conception of the mind‐brain connection allows many psychological and neuropsychological findings associated with the apparent physical effectiveness of our conscious volitional efforts to be explained in a causal and practically useful way. According to this quantum approach, conscious human beings are invested with degrees of freedom denied to the mechanistic automatons to which classical physics reduced us.     

ANIMALIA,HOMO, AND THE KINGDOM OF GOD

Abstract. I selectively and critically review the state of knowledge about human evolution and the place of humans vis‐à‐vis living apes, with emphasis on bipedal posture and locomotion, expansion of the brain and associated cognitive capacities, speech, tool behavior, culture, and society. I end with a personal perspective on God and Heaven.     

审美的神经机制研究及其美学意义

本文主要介绍了审美神经机制研究的初步成果,特别有关Zeki,Solso等人开创性的研究工作,并着重讨论了这些研究工作的美学意义,指出审美神经机制的研究不但在美学理论的确证方面,具有更强的说服力和广泛的应用性,而且在21世纪美学理论的重建方面,也一定会起着不可替代的重要作用。     

论神经哲学的兴起

人类心身问题的研究一直是科学界关注的热点。近年来,国外学者将神经科学与哲学研究统一起来,集合两门学科的研究方法、综合双方的研究成果,以此来共同推进人类心身问题的研究,因此诞生了一门介于神经科学和哲学之间的独立学科,它有着学科交叉的研究领域和特殊的跨学科研究方法,这门学科就是神经哲学。     

Dream content: Individual and generic aspects

Dream reports were collected from normal subjects in an effort to determine the degree to which dream reports can be used to identify individual dreamers. Judges were asked to group the reports by their authors. The judges scored the reports correctly at chance levels. This finding indicated that dreams may be at least as much like each other as they are the signature of individual dreamers. Our results suggest that dream reports cannot be used to identify the individuals who produced them when identifiers like names and gender of friends and family members are removed from the dream report. In addition to using dreams to learn about an individual, we must look at dreams as telling us about important common or generic aspects of human consciousness.     

The effects of reinforcer magnitude on timing in rats

The relation between reinforcer magnitude and timing behavior was studied using a peak procedure. Four rats received multiple consecutive sessions with both low and high levels of brain stimulation reward (BSR). Rats paused longer and had later start times during sessions when their responses were reinforced with low-magnitude BSR. When estimated by a symmetric Gaussian function, peak times also were earlier; when estimated by a better-fitting asymmetric Gaussian function or by analyzing individual trials, however, these peak-time changes were determined to reflect a mixture of large effects of BSR on start times and no effect on stop times. These results pose a significant dilemma for three major theories of timing (SET, MTS, and BeT), which all predict no effects for chronic manipulations of reinforcer magnitude. We conclude that increased reinforcer magnitude influences timing in two ways: through larger immediate after-effects that delay responding and through anticipatory effects that elicit earlier responding.
