论西周易卦与《易经》

中国易学史在经历了由伏羲时代到炎黄时代再到夏商时代的滥觞期之后,迨西周初期则呈现出甲骨易卦和金文易卦并蒂兴盛的璀璨局面;到了西周中后期,又出现了陶文易卦,特别是陶拍易卦的出现,说明《易经》六十四卦的卦序结构已从根本上解决。这一切充分说明:《易经》一书在经历了数千年的怀胎之后,到了西周中后期,正在履行它的一朝分娩之重任。     

压力对“蚁族”群体心理健康的影响:希望的调节作用

以广州市棠下、上社、岑村、赤沙等地340名"蚁族"(高校毕业生低收入聚居群体)为被试,采用成人希望特质量表(ADHS)、压力知觉量表(CPSS)、一般心理健康问卷(GHQ),考察了"蚁族"群体的希望水平,并分析了希望在压力和心理健康之间的调节作用。结果发现:①从整体上看,该群体的希望处于中等偏上水平。②压力对于心理健康水平有显著的负向影响;希望能够起到压力缓冲作用,调节压力与一般健康问题、忧郁情绪和自我肯定感之间的关系。③希望对心理健康的忧郁、自我肯定维度的调节作用大小不同,对于忧郁情绪的调节作用更大,而对自我肯定调节作用较小。     

慢性心房颤动导管消融的若干争议

随着房颤消融技术的迅速发展和提高,阵发性房颤射频消融已列入Ⅰ类推荐,慢性房颤射频消融也列入Ⅱa类适应证.肺静脉电隔离仍是慢性房颤消融的基石.但由于慢性房颤病因不一,机制更加复杂,除了肺静脉电隔离外,还需进行心房基质改良,其消融策略、术式、终点还存在若干争议.     

几种场相依/场独立测量工具间的相关研究

镶嵌图形测验、框线测验和认知偏差任务是目前国际上常用的三种场相依/场独立的测量工具。该研究发现：1）在框线测验中,个体不受背景信息干扰的能力,与整合背景信息的能力存在显著正相关关系;2）执行镶嵌图形测验愈佳者,执行框线测验的绝对任务与相对任务也愈佳;3）但认知偏差任务与镶嵌图形测验以及框线测验均无相关关系。因此,个体在感知过程中对场的利用,与其在推理决策过程中对场的利用,很可能是两个独立的心理过程。此外,由于镶嵌图形测验与智商测验有相关,框线测验可能更适合于跨文化心理学中对场相依/场独立概念的测量。     

全球化中的伦理认同与伦理冲突

全球化不仅改变着世界各国经济、政治格局,而且在思想文化领域亦产生了深远影响。这种影响在伦理维度上以伦理认同与伦理冲突的矛盾现象凸显出来。面对全球化中伦理认同与伦理冲突并存的复杂态势,合理的战略选择应该是:理性审视和反思全球化中的伦理认同和伦理冲突,以生态价值观引导下的伦理多元主义应对全球化的文化挑战。     

道德契约论的“启发” ——从高蒂耶的“约束性最大化”谈起

大卫.高蒂耶认为契约论可以把道德构筑在"审慎理性"的基础之上,这一努力因其核心概念"约束性最大化"所隐含的"道德理性"而归于失败。同一理论框架下的双重理性基础使契约论可以从"效用最大化"的视角为规范优先提供某种合情理的说明。这种说明尽管不是一种严密的"证明",却是一种合情理的"启发"。     

Post-training intra-basolateral amygdala infusions of norepinephrine block sevoflurane-induced impairment of memory consolidation and activity-regulated cytoskeletal protein expression inhibition in rat hippocampus

Considerable evidence indicates that the noradrenergic system of the basolateral amygdala (BLA) participates in the consolidation of various types of emotionally arousing memories. We previously reported that administration of an anesthetic-dose of sevoflurane immediately after continuous multiple-trail inhibition avoidance (CMIA) training impaired memory consolidation. This experiment investigated whether posttraining noradrenergic activation of the BLA is sufficient to reverse the memory impairing effect of sevoflurane. Adult male Sprague-Dawley rats received bilateral injections of norepinephrine (NE 0.3, 1.0, or 3.0 μg/0.5 μl) or normal saline (NS 0.5 μl) immediately after training in a CMIA paradigm. Subsequently, the rats were exposed to sevoflurane (2% inspired) or air for 2h. Norepinephrine produced a dose-dependent enhancement of memory consolidation on a 24-h retention test. The highest dose of NE tested (3.0 μg/0.5 μl) blocked sevoflurane-induced impairment of memory consolidation and reversed the inhibitory effect of sevoflurane on activity-regulated cytoskeletal protein (Arc) expression in the hippocampus 2h after training. These findings provide evidence that the mechanism mediating the memory-impairing effect of sevoflurane involves a network interaction between the BLA noradrenergic system and modulation of Arc protein expression in the hippocampus.     

具身社会认知：认知心理学的生态学转向

具身社会认知是具身认知同社会认知对话的产物,这种对话从三个维度展开,即具身自我认知、具身人际认知、具身群体认知。本研究不仅论证了具身认知的视角提高了传统社会认知心理学的生态效度,而且从进化心理学、镜像神经元视角对具身社会认知的现象进行了探析。具身社会认知作为一种研究思潮,面临着许多挑战：(1)具身社会认知是对行为主义研究范式的回归;(2)具(体)身(体)是社会认知过程的一种附带现象。     

说谎者悖论及其相关悖论的一种解决

依本文之见,说谎者悖论以及某些与之相关的悖论之被导出源于对某些不合理的前提的接受;而这些前提之被接受又源于对＂是真的＂与＂是假的＂这两个词的关键语义特性缺乏认识。本文为决定这些语义特性的基础提供了说明;这一基础包含两个论点,第一,每一语句均有其含义;第二,每一语句陈说的字面内容是一个命题态度的内容,因而具有某种一般形式。借助于这一基础,本文为这两个词构造了一个不同于传统意义上的塔尔斯基式真理理论的意义理论以说明这些特性,并借助于该理论论证说谎者悖论及其某些相关悖论的导出没有根据。     

The auditory motion aftereffect: its tuning and specificity in the spatial and frequency domains

In this paper, the auditory motion aftereffect (aMAE) was studied, using real moving sound as both the adapting and the test stimulus. The sound was generated by a loudspeaker mounted on a robot arm that was able to move quietly in three-dimensional space. A total of 7 subjects with normal hearing were tested in three experiments. The results from Experiment 1 showed a robust and reliable negative aMAE in all the subjects. After listening to a sound source moving repeatedly to the right, a stationary sound source was perceived to move to the left. The magnitude of the aMAE tended to increase with adapting velocity up to the highest velocity tested (20 degrees/sec). The aftereffect was largest when the adapting and the test stimuli had similar spatial location and frequency content. Offsetting the locations of the adapting and the test stimuli by 20 degrees reduced the size of the effect by about 50%. A similar decline occurred when the frequency of the adapting and the test stimuli differed by one octave. Our results suggest that the human auditory system possesses specialized mechanisms for detecting auditory motion in the spatial domain.
