艰难的安乐死

安乐死立法难,依法更难,执法难上难。有法不依,执法不严;一失足成千古恨,再回头已是百年身。     

Semantic and subword priming during binocular suppression

In general, stimuli that are familiar and recognizable have an advantage of predominance during binocular rivalry. Recent research has demonstrated that familiar and recognizable stimuli such as upright faces and words in a native language could break interocular suppression faster than their matched controls. In this study, a visible word prime was presented binocularly then replaced by a high-contrast dynamic noise pattern presented to one eye and either a semantically related or unrelated word was introduced to the other eye. We measured how long it took for target words to break from suppression. To investigate word-parts priming, a second experiment also included word pairs that had overlapping subword fragments. Results from both experiments consistently show that semantically related words and words that shared subword fragments were faster to gain dominance compared to unrelated words, suggesting that words, even when interocularly suppressed and invisible, can benefit from semantic and subword priming.     

分布式群体在动态系统控制决策中的内隐学习

采用计算机网络模拟技术,考察分布式群体在动态系统控制决策过程中对系统规则的内隐学习效应及其迁移。结果表明,在决策者的显性规则知识量极少且没有增加的情况下,决策绩效随决策进程适应性提高。决策者所能报告的规则知识量与决策绩效的相关也不显著。同时,当决策任务目标转换时,决策的高绩效得以维持。这表明群体决策者能对动态系统规则进行内隐学习,且能正迁移到类似的决策情景中。研究进一步指出,群体决策行为的动态适应与内隐过程有关。     

不同情绪效价的DRM词表对错误记忆的影响

请49名在校大学生对自编的36个具有不同情绪效价的DRM词表进行评定,再以60名在校大学生为实验对象考察不同情绪效价的DRM词表对错误记忆的影响。结果发现,(1) 负性和中性DRM词表产生的错误记忆量显著高于正性DRM词表;(2) 被试在“记得/知道/猜测”判断上对负性和中性词表的关键诱饵倾向于“知道”,而对正性词表的关键诱饵更倾向于“记得”。结果表明,DRM词表本身所具有的情绪与人为诱发的情绪,对错误记忆的影响具有不同的性质和特点。     

大脑半球损害病人的汉字抄写研究

对３７例左、右半球病变者进行汉字抄写等测查。结果发现：１．大脑半球病变影响汉字抄写,但左和右半球病变者、皮层和皮层下病变者、失语和非失语病人的汉字抄写成绩无明显差异;２．无论有无失语,抄写与听写都无相关;与画图的关系取决于文化背景,即文化水平低者（无读写能力）汉字抄写与临摹画图高度相关,并受半测空间疏忽影响,而有读写能力者汉字抄写不受以上因素影响。由此推测：不同的汉字书写方式有着不同的神经机制;无汉字读写能力者抄写过程主要与右脑有关,而有读写能力者汉字抄写时双脑并用。     

彝族、白族和纳西族大学生的基本颜色词分类

运用自然分类和多维标度法,研究了彝族、白族和纳西族237名大学生对11种基本颜色词的分类。结果表明,三个民族的大学生对11种基本颜色词的分类有一致之处,但也有文化差异。主要表现在：⑴基本颜色词的分类数目不同;⑵基本颜色词的类别不同;⑶基本颜色词语义空间的维度不完全相同;⑷每一类别中包含的颜色词及颜色词的数目不同。这些差异体现了文化和语言对颜色认知的影响     

权利游戏——中国文化中的人情对腐败意识的影响

腐败是危害社会公正、法治的不良现象。为考察中国文化中的人情对腐败意图的影响,通过两轮问卷向190名大学生进行调查,结果发现:(1)人情不是单一整体,而是包含情感、资源、规范三个维度的复杂构念;(2)人情中的资源维度显著正向影响腐败意图,并且这一过程不受道德认同的影响。研究结果说明,为建立一个清廉、和谐的社会,人情中的不良成分,如利用人情资源获得优先对待必须被避免。     

Dorsomedial prefrontal cortex 5-HT6 receptors regulate anxiety-like behavior

The dorsomedial prefrontal cortex (dmPFC) plays a very important role in decision-related and anxiety-related information processing. It has enriched 5-HT6 receptors; however, the precise role of dmPFC 5-HT6 receptors in anxiety remains to be fully investigated. In this study, we injected dmPFC with the 5-HT6 receptor agonist EMD 386088 and antagonist SB 271046 using stereotactic technology. 5-HT6 receptor activation in mice increased time spent in the center area on the open-field test, increased exploration of the open arms on the elevated plus maze test, and increased ratio on the social interaction test. 5-HT6 receptor inactivation induced the opposite effects. In brain slices, EMD 386088 decreased both spontaneous inhibitory postsynaptic currents (sIPSC) and spontaneous excitatory postsynaptic currents (sEPSC), while SB 271046 only increased sEPSC. These effects of EMD 386088 and SB 271046 could be reversed by the GABA_A receptor antagonist bicuculline (BMI) and positive allosteric modulator clonazepam (CLZ), respectively. Our results suggest that neurotransmission in the dmPFC by 5-HT6 receptor activation and inhibition may play an important role in anxiety-like behavior, and may provide new insight into the pathological mechanism and potential target of anxiety disorders.     

A relational recasting of the principles of emotional competence

ABSTRACT

Carolyn Saarni’s theory of emotional competence has made a central contribution by directing attention to some important functions of emotion in social interaction. Her work is permeated with examples of how emotions function within both successful and unsuccessful social interactions and relationships. An examination of her stated principles of emotional competence suggest in places a perspective that is primarily intrapsychic in nature, harking back to the early roots of emotion theory and research. In this piece, we note where Saarni has advanced implications of a relational theory of emotion for understanding emotional competence. In addition, we reframe some of Saarni’s principles to make them more consistent with current relational approaches to emotion. Finally, we offer additions and extensions that we believe are compatible with the general direction of her thinking before her untimely death.     

Creating Play Atmosphere and Time for Children in Chinese Kindergarten: Difficulties and Reflection

Schools’ busy situation is far away from its Greek root “Scholé” that means leisure time compared with political duty and war at that era which is also similar in ancient China. From the leisure point of view, school should be relax and free for young children in kindergarten. This means that play should take the most time on the schedule. Unfortunately, Political class skillfully disseminating serious competition among nations to deliver anxiety on young generations’ education to the public,which makes parents and school system highly valued formal learning much more than play. Chinese kindergarten may be have the longest formal learning time due to its history emphasis on learning from the model. Endure hardship as the basic habit from the younger children for the nature of life is full of hardship in Chinese philosophy. These underpinned ideas encounter great challenges from the Western early childhood education which puts more emphasis on play. Play is conceived as children’s life itself, in which integrated learning can happen and is much more suitable and abundant for young children than formal learning. Although Chinese Educational Ministry promulgated kindergarten work regulation and educational guideline to make play as the basic activity in 1996 and 2001,there are still lots of factors that impede kindergartens implement play in practice. Lack of free time in kindergarten both on schedule and in fact is the obvious sign. This paper wants to reflect those factors in cultural perspective and try to use variety meanings of time especially subjective time to analysis the practice on reconstructing kindergartens’ play atmosphere and time, and the findings on creating different inter-subjective time for young children.
