Gender and early Chinese cosmology revisited

This article proposes to challenge the generally accepted argument that early Chinese cosmology transcended questions of gender by presenting a new analysis of the Xian 咸 and other relevant hexagrams in the Classic of Changes (Yijing 易經), as well as their classical commentaries. This new study shows that, the concept of the resonant gendered relation of husband and wife played a significant role in constructing social relations and cosmological modes implied in this significant classic. The harmonious husband–wife relation was placed at the center of the social, political, and cosmic order. This may be one reason that from about the same period, Confucian moral and political philosophy always emphasized the importance of ordering one’s family before governing the state. In this sense, the Chinese cosmology, as seen in the Classic of Changes, does not transcend gender; on the contrary, it is gendered.     

东莨菪碱对吗啡诱导的大鼠行为敏感化的影响

药物重复处理导致的行为敏感化与成瘾过程密切相关。本实验检验东莨菪碱对吗啡诱导的大鼠行为敏感化发展和转化的影响。实验一动物分为3组,分别进行生理盐水（对照组）、吗啡（10mg/kg,吗啡组）、吗啡（10mg/kg）＋东莨菪碱（3mg/kg,吗啡-东莨菪碱组）前处理,36小时腹腔注射4次（第1~2天）。自然戒断7天（第3~9天）。第10天,所有动物均使用吗啡（4mg/kg）激发,记录动物的自发活动量;第24天,吗啡组和吗啡-东莨菪碱组动物重复第10天的操作。实验二动物分为3组,分别接受生理盐水（对照组）、吗啡（10mg/kg,吗啡组）、吗啡（10mg/kg,吗啡-东莨菪碱组）处理,36小时腹腔注射4次（第1~3天）;间隔12小时后,3组动物分别接受生理盐水、生理盐水和东莨菪碱（3mg/kg）处理,仍为36小时腹腔注射4次（第3 ~5天）。第6~9天不进行药物处理。第10天和第17天,分别使用吗啡（4mg/kg）激发,记录动物的活动量。记录时间均为两小时(10分钟为一个记录单元)。结果表明,东莨菪碱能够抑制吗啡诱导的行为敏感化的发展,一定程度上也能够延缓行为敏感化的转化但没有阻断这种转化     

MK-801与环境线索交互作用对吗啡行为敏感化的影响

为探讨MK-801与环境线索交互作用对吗啡诱导行为敏感化的影响,将42只大鼠随机分为对照组,MK-801组,吗啡组（匹配和非匹配）和MK-801+吗啡组（匹配和非匹配）。行为敏感化模型建立分为发展期,戒断期和表达期三个阶段。实验结果发现：同时给予MK-801（0.1mg·kg-1）会促进吗啡（5mg·kg-1）诱导大鼠行为敏感化的发展,而且会使MK-801成为大鼠行为敏感化表达所必需的条件性刺激。MK-801的内部线索作用过强,从而削弱了环境的外部线索作用。研究结果表明：MK-801对吗啡诱导行为敏感化的影响存在状态依赖（state-dependency）现象,提示在NMDA受体与行为敏感化关系的研究中应考虑选择刺激特性更小的药物

伪装情绪的人际影响及其作用机制

伪装情绪是指在情绪交互的过程中, 人们展现实际不存在的积极或消极情绪, 放大亦或是压抑原本的情绪。伪装情绪是一种策略选择的结果, 表现者所展现的情绪在当下可能并未发生, 但却能在某种程度上令人信服。目前关于伪装情绪的研究比较分散, 对于伪装情绪人际影响及其作用机制还存在着一定争议。现有文献多从博弈过程、亲社会行为情境、组织情境和领导效果四个方面对伪装情绪的人际效应进行探讨, 其中相关的机制包括情绪接受者的情感反应及“以己度人”的内心过程。未来的研究可以从情绪接受者、群体伪装、伪装情绪效价、认知神经机制以及文化等方面, 对伪装情绪展开深入系统性的研究。     

行为遗传学:解决面孔特异性问题争论的新思路

面孔刺激的加工存在特异性,但"特异性"的具体内涵仍存在争议.面孔特异性假说认为面孔刺激具有特异性;而专家假说则认为存在特异性的是整体加工的模式.通过对相关领域近年来主要的研究结果的总结,发现争论中混淆了两个概念--加工类型和刺激类型,二者正交分解可将争论归纳为三个假设:1)面孔整体加工特异性的假设;2)面孔刺激特异性的假设;3)专家加工特异性的假设.在未来的研究中,行为遗传学可为解决该争论提供合适的方法.     

"爱情"与"友谊"概念表征的差异——基于字词联想的比较

运用字词联想法对大学生爱情和友谊概念表征的异同进行了初步探究.以"爱情"和"友谊"为靶词,让被试进行自由联想,之后对搜集到的11136个联想词进行内容分析,在前人研究的基础上最终编码为18个范畴.结果显示,爱情相对需要更多的理性与情感投入、经历更多的痛苦、肩负更多的责侄,容易联想到婚姻、家庭、命运缘分,而友谊较少牵扯.与爱情相比,友谊更易于转化为爱情,而经历过爱情的人很难再回归到友谊.这些结果与日常观念相符,为如何处理爱情和友谊的关系提供了实征指导.     

知觉运动学习中的背景干扰效应和元认知监测

选取大学生为被试,采用两因素混合实验设计,以预期按键反应作为知觉运动学习任务.在运动学习任务中,设置了集中练习和分散练习两种练习方式以及三个练习一测试组块.通过分析不同练习方式和练习-测试组块对练习成绩、测试成绩以及元认知监测的影响,考察运动知觉学习的背景干扰效应、练习伴随低估效应以及元认知监测的依据.结果发现: (1)缩短练习与测试之间的时间间隔,经典的背景干扰效应没有出现; (2)在知觉运动学习的多组块练习过程中.元认知监测准确性没有出现练习伴随低估效应; (3)集中练习组更多地以当前的练习成绩作为依据进行预测,从而导致了对预测的高估.     

Asymmetrical attention allocation to dissimilar and similar attitudes

Evaluations of others are sometimes influenced more by their dissimilar than similar attitudes. The authors investigated this similarity–dissimilarity asymmetry at the level of stimulus processing. In a variant of the Stroop task in Experiment 1 (N = 50), dissimilar attitudes of the participants interfered more with their color-naming performance than did similar attitudes. In a dual-task paradigm of Experiment 2 (N = 92), a greater attention allocation to dissimilar than similar attitudes disappeared when the cognitive load was low, but not when it was high. Findings illustrated the similarity–dissimilarity asymmetry at the level of stimulus processing, and presented the asymmetry as another case of the fundamental positive–negative asymmetry. Implications and alternative interpretations of these findings are discussed.     

Variation in coordination of a discrete multiarticular action as a function of skill level

The authors investigated coordination modes that emerged as a function of the interaction between skill level and task constraints in a multiarticular kicking action. Five skilled, 5 intermediate, and 5 novice participants attempted to satisfy specific height and accuracy constraints in kicking a ball over a barrier. Skilled and intermediate groups demonstrated a functional coordination mode involving less joint involvement at the proximal joints and greater joint involvement at distal joints, mimicking a chip-like action in soccer. Conversely, the novice group tended to produce larger ranges of motion throughout the kicking limb in a driving-like kicking action. Key differences were also found for task outcome scores, joint angle-angle relations, and ball-trajectory plots between the skilled and intermediate groups and the novice group. Findings from this study demonstrated that joint involvement during this discrete multiarticular action is a function of skill level and task constraints rather than a consequence of a global freezing-freeing strategy suggested in some previous research. The authors also highlight the merit of using a model of the acquisition of coordination in examining how coordination modes for multiarticular actions differ as a function of skill.
