慢性应激对大鼠空间学习记忆及海马和前脑皮层突触体膜流动性的影响

慢性应激对学习记忆功能的影响是神经科学的热点问题, 在脑内, 海马和前额叶是与学习记忆功能密切相关的重要脑区, 也是应激易累及损伤的主要靶区。膜流动性的改变在神经细胞功能活动中起重要作用。为探讨慢性应激对大鼠空间学习记忆功能的影响及前脑皮层和海马突触体膜流动性的作用。采用多因素慢性应激动物模型, 通过开场试验和Morris水迷宫测试大鼠行为及空间学习记忆能力; 并且测定大鼠前脑皮层和海马突触体膜流动性和突触体内游离Ca2+浓度的变化。研究结果显示, 与对照组相比, 应激组大鼠在应激后即刻, 在新异环境中的自发活动和探究行为显著降低(p<0.05, p<0.01), 空间学习记忆能力明显下降(p<0.05, p <0.01); 并且应激组大鼠前脑皮层和海马突触体膜流动性显著降低(p <0.05, p <0.01); 而突触体内游离Ca2+浓度的显著增加 (p <0.05, p <0.01)。停止应激后一周, 应激大鼠的各项指标有所恢复, 但仍未达到正常水平。研究结果提示, 慢性应激引起大鼠明显的开场行为改变和空间学习记忆功能障碍, 这些变化可能与突触体膜流动性和突触体内游离Ca2+浓度的变化密切相关。     

复杂图形表象产生的认知加工机制

采用Kosslyn双任务分离的研究范式,通过两个实验考察了复杂图形表象产生的认知加工机制。实验1提出了当要求被试在产生动物的部分表象时,大脑左半球明显反应更快;而当要求被试产生客体整体特征的表象时,并没有出现大脑半球的优势效应。实验2采用控制任务进一步证实大脑两半球不同的优势效应,研究发现当同样的任务以知觉形式完成时,没有大脑半球的优势效应。实验结果表明,在复杂图形表象产生的过程中,当产生部分表象时,大脑左半球有显著优势;而当产生整体表象时,两半球起同样作用。此结果进一步拓展了Kosslyn提出的大脑半球专门化假说。     

Effects of shape parameters on the attractiveness of a female body

Various researchers have suggested that certain anthropometric ratios can be used to measure female body attractiveness, including the waist to hip ratio, Body Mass Index (BMI), and the body volume divided by the square of the height (Volume-Height Index). Based on a wide range of female subjects and virtual images of bodies with different ratios, Volume-Height Index was found to provide the best fit with female body attractiveness, and the effect of Volume-Height Index can be fitted with two half bell-shaped exponential curves with an optimal Volume-Height Index at 14.2 liter/m2. It is suggested that the general trend of the effect of Volume-Height Index may be culturally invariant, but the optimal value of Volume-Height Index may vary from culture to culture. In addition to Volume-Height Index, other body parameters or ratios which reflect body proportions and the traits of feminine characteristics had smaller but significant effects on female body attractiveness, and such effects were stronger at optimum Volume-Height Index.     

Ghosted?: Navigating strategies for reducing uncertainty and implications surrounding ambiguous loss

Ghosting is the unilateral dissolution process of ceasing communication through media. When ghosted, non‐initiators are often left without the ability to navigate the resulting uncertainty or impending dissolution processes. Utilizing uncertainty reduction theory and ambiguous loss, this investigation explores effective and ineffective strategies used to find answers, reduce uncertainty, and navigate post‐dissolution consequences. Employing two studies from Amazon's Mechanical Turk, a thematic analysis to delineate and affirm categories—7 effective and ineffective strategies and 11 categories of personal and relational implications after being ghosted—was used. These studies provide insight about non‐initiators process to resolve their uncertainty and highlight ramifications from ambiguity that non‐initiators experience after being ghosted. These findings discuss connections to knowledge acquisition, closure processing, and consequences of ghosting.     

童年期虐待对网络成瘾的影响:有调节的中介效应

本研究基于有限自制力理论考察童年期虐待对网络成瘾的影响及其作用机制。以1162名大学生为被试,采用童年期虐待量表、自我控制量表、感恩量表和网络成瘾量表进行测试,结果发现：（1）童年期虐待和自我控制、感恩呈显著负相关,与网络成瘾成显著正相关;自我控制与感恩呈显著正相关,与网络成瘾呈显著负相关;感恩与网络成瘾呈显著负相关。（2）自我控制在童年期虐待和网络成瘾之间起中介作用。（3）“童年期虐待→自我控制→网络成瘾”这一中介路径的前半段受到感恩的调节;与高感恩个体相比,童年期虐待对低感恩个体的自我控制的影响更小。感恩不仅不能缓冲童年期虐待对自我控制的负面影响,反而会增强这一过程,提示我们注意积极特质在特定情境下的消极作用。     

谈谈素山信仰的当代定位问题

泰山是中国人心目中的神山、圣山,是古代中国文明和信仰的象征.其原生的信仰和文化,几千年来渗透、辐射到中国社会生活的多个层面,对民族心理和民族文化产生了重要的影响.然而,当代对泰山原生信仰和文化的内涵之研究,以及对这种信仰和文化的时代定位问题的研究,尚属薄弱.泰山文化博大精深,异彩纷呈,可它的核心是什么?特色是什么?当代泰山宗教信仰、文化以及旅游经济,如何来传承这种传统,需要一种信仰的定位,一种在新时代背景下赋予新意的定位.基于此,本文试图梳理泰山原生信仰和文化的脉络,进而探讨当代泰山信仰应如何定位的问题.     

Parental Exposure to Mass Violence and Child Mental Health: The First Responder and WTC Evacuee Study

Children’s reactions after being exposed to mass violence may be influenced by a spectrum of factors. Relatively unexplored is the extent to which family exposure to mass violence may affect child mental health, even when these children have not been directly exposed. In a representative sample of NYC public school children assessed 6 months after the September 11, 2001 attack on the World Trade Center (WTC), seemingly elevated rates of psychopathology were recorded among children of WTC evacuees. Children of NYC First Responders (police officers, EMTs, and fire fighters) displayed a complex pattern of response to the WTC attack. Overall, the findings from this previous study support putative transmission of trauma to children whose parents were exposed to the WTC attack. The “Children of First Responder and WTC Evacuee Study”—a two-site longitudinal study—is currently underway in the United States (New York City) and in Israel (Tel Aviv area) in an effort to understand the impact of different patterns of mass violence. The NYC sample permits us to examine the impact of a rare instance of mass violence (e.g., WTC attack), while the Israeli sample provides information about repeated and frequent exposure to mass violence brought about by acts of terrorism. In addition, children’s exposure to mass violence is considered in the context of their exposure to other potentially traumatic events. This study aims to improve our general understanding of the impact of mass violence on children, especially the psychological effects on children whose parents’ work experiences are by nature stressful. Knowledge generated by this study has implications for guiding efforts to meet the needs of children who have, directly or through a family member, been subjected to rare or infrequent mass violent event as well as to children whose exposure to mass violence is part of daily life.
