上下意象图式向抽象概念映射的心理现实性研究

通过考察上下意象图式隐喻的映射机制和形成机制,验证其向抽象概念的映射具有心理现实性.实验一中,学龄期儿童阅读与图式一致材料反应时,较阅读与图式不一致材料反应时短,说明上下意象图式存在于概念水平,并在即时阅读中被激活.实验二中,学龄前幼儿表现出物品摆放的上下方位偏好差异,表明幼儿在概念形成过程中,抽象概念与空间上下方位存在体验性联结.研究证明:部分抽象概念表征具有上下方位线索,人们借助上下意象图式建构抽象概念.     

同伴互动类型对三年级小学生写作水平的影响

研究通过对比同伴辅导、合作、协作等三种同伴互动写作方式与个体化写作教学干预前后,三年级学生独立写作水平的变化,了解同伴互动类型对初学者写作水平的影响.结果发现,和个体化写作相比,三种同伴互动写作方式均更有利于整体写作水平和"结构"维度写作水平的提高;但合作写作最为突出,不仅在各个维度都优于个体化写作,而且在"选材"维度上还优,于同伴辅导写作和协作写作.这说明,社会性互动有利于初学者写作水平的提高,且主要表现为提升记叙文的结构完整性和层次清楚性;但只有兼顾"个人责任"和"高平等性、相互性",社会性互动对写作的促进作用才能更加充分地发挥.     

基于MJT的道德结构验证性分析研究

从科尔伯格提出道德认知发展概念至今,已经出现对道德认知发展的几种不同解释,其中较为著名的包括阶段论、水平论和认知图式论.本研究通过对一份道德判断测验的数据进行分析,采用建立模型的实证方法,试图验证已有的几种道德认知结构理论的正确性.研究表明:道德发展过程的确包含六个阶段,它们是按照一定顺序发展的.同时,道德发展过程中还出现三个水平,并先后建立了三种不同的认知图式.     

老年人社会支持、孤独感与主观幸福感的关系

选取天津市379名老年人,采用"纽芬兰纪念大学幸福感量表"、"社会支持最表"和"情绪一社会孤独问卷"进行调查,以探讨老年人社会支持、孤独感与主观幸福感的关系.结果表明,不同工作状况的老年人在社会支持、孤独感及主观幸福感上均呈显著差异;不同社会支持水平老年人的孤独感、主观幸福感具有显著差异;老年人社会支持,孤独感与主观幸福感各维度间相关显著.     

A Work-Life Identity Model of Well-Being: Towards a Research Agenda Linking Quality-of-Work-Life (QWL) Programs with Quality of Life (QOL)

QWL is conceptualized in terms of the interface between employee role identities and work resources. QWL programs serve to enhance QOL by (1) providing appropriate work resources to meet the expectations of employee role identities, (2) reducing role conflict in work and non-work life, (3) enhancing multiple role identities, (4) reducing role demands, (5) reducing stress related to work and non-work role identities, and (6) increasing the value of the role identity. We describe a variety of QWL programs related to work life (decentralized organization structures, teamwork, parallel structures, ethical corporate mission and culture, the organization work schedule, etc.) and non-work life (work at home, flextime, compressed work week, part-time work arrangements, job sharing, etc.) and show how they serve to enhance QOL using the language of work-life identity. Doing so helps develop a research agenda based on the work-life identify model.     

态度改变：说服策略研究的回顾与展望

态度是社会心理学研究的重要领域,近年来研究者发现通过说服可以改变个体的态度,所以态度的说服策略成为一个研究的重点。说服包括了陈述论据和事实,推理,做结论和说明所推荐行为方式的积极效果,所有的一切都是为了使受众相信并且按照这种行为方式行事。本文沿着历史的脉络,从不同的角度阐述了各种说服策略的理论解释及其实验研究,并在此基础上叙述了说服策略未来研究趋势。     

东南亚那珈信仰的起源与嬗变——语言民族学视角的分析

东南亚那珈信仰主要见于泰、老、柬、缅四国,是印度河城市文明传播时期,中南半岛与古印度两地蛇崇拜文化交流的结果.在后继的印度宗教文明的冲击下,东南亚那珈信仰发生嬗变,在婆罗门教占统治地位时,得到较大程度的保留;当南传佛教取得正统地位后,那珈信仰大大退化但没有消失.     

人类性行为的伦理"真、善、美"

Upregulation of hippocampal TrkB and synaptotagmin is involved in treadmill exercise-enhanced aversive memory in mice

Cognitive functions usually involve various synaptic proteins and neurotrophic factors in the hippocampus. However, whether treadmill exercise can improve learning and memory by upregulating some of these molecules remain unraveled. To address this question, male BALB/c mice were divided into control and exercise groups, the latter group went through 4 weeks of treadmill exercise training. At the end of exercise training period, they were either tested for passive avoidance (PA) performance or sacrificed for quantifying the hippocampal levels of brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B (TrkB, the BDNF receptor), synaptotagmin (a Ca²⁺-dependent synaptic vesicle protein), and SNAP-25 (a presynaptic vesicular fusion protein). Our results showed that treadmill exercise training (1) increased the retention latency without affecting the fear acquisition in the PA test, (2) transiently increased the hippocampal BDNF level at 1, 2, and 4 h after the completion of exercise training, and (3) persistently increased the hippocampal protein levels of full-length TrkB, phosphorylated TrkB and synaptotagmin, but not truncated TrkB or SNAP-25. Moreover, the protein expression level of full-length TrkB or synaptotagmin was positively correlated with PA performance in mice. Finally, inhibition of TrkB signaling by K252a abolished the exercise-facilitated PA performance and upregulation of TrkB and synaptotagmin. Taken together, these data suggest that the upregulation of TrkB and synaptotagmin in the hippocampus contributes to the exercise-facilitated aversive memory.     

Acute ethanol ingestion impairs appetitive olfactory learning and odor discrimination in the honey bee

Invertebrates are valuable models for increasing our understanding of the effects of ethanol on the nervous system, but most studies on invertebrates and ethanol have focused on the effects of ethanol on locomotor behavior. In this work we investigate the influence of an acute dose of ethanol on appetitive olfactory learning in the honey bee (Apis mellifera), a model system for learning and memory. Adult worker honey bees were fed a range of doses (2.5%, 5%, 10%, or 25%) of ethanol and then conditioned to associate an odor with a sucrose reward using either a simple or differential conditioning paradigm. Consumption of ethanol before conditioning significantly reduced both the rate of acquisition and the asymptotic strength of the association. Honey bees also exhibited a dose dependent reduction in arousal/attention during conditioning. Consumption of ethanol after conditioning did not affect recall 24h later. The observed deficits in acquisition were not due to the affect of ethanol on gustatory sensitivity or motor function. However, honey bees given higher doses of ethanol had difficulty discriminating amongst different odors suggesting that ethanol consumption influences olfactory processing. Taken together, these results demonstrate that an acute dose of ethanol affects appetitive learning and olfactory perception in the honey bee.
