西堂智藏生卒年考

<正>西堂智藏为马祖道一最重要的门人之一,在中国禅宗史上有很高的地位,他有不少新罗门人,法流东国,化及海外,对于中国禅宗的对外传播和中韩两国的文化交流贡献很大。智藏生卒年学术界尚有争论。本文指出其生卒当以唐技《龚公山西堂敕谥大觉禅师重建大宝光塔碑铭》为准,并依据其新罗门人寂忍慧彻之碑文对此进行了论证。     

当代心理学发展的一种新取向--进化心理学

进化心理学是近年在西方心理学中出现的一种新的研究取向,目前仍没有一个明确的概念和系统的理论。其基本主张是：过去是理解心理机制的关键;功能分析是理解心理机制的主要途径;心理机制是在解决问题的过程中演化形成的;模块性是心理机制整体组织的特性;人的行为是心理机制和环境互动作用的结果。进化心理学的发展既有意义同时也存在局限。其意义是：其发展与当代科学发展趋势相一致;它的研究促进了对人性和心理的进一步思考。局限是：具有遗传决定论的倾向;方法论存在一定的缺陷,忽视了文化对进化的意义等等。     

乳头体和隔区在大鼠条件性味觉痕迹的形成和保存中的作用

本工作是在前一工作的基础上,进一步研究分别电损毁有关回路的乳头体、隔区,对以糖精水为条件刺激。氯化锂腹腔注射引起中毒作为非条件刺激的条件性糖精厌恶痕迹的形成和保存的影响。结果表明,无论是损毁乳头体,或者隔区,对条件性糖精厌恶痕迹的形成和保存均无影响。说明在本实验条件下,这种条件性味觉痕迹的形成与保存,不依赖边缘系统的乳头体、海马、隔区这些回路的参与,这就进一步说明味觉信号的记忆确有其不同于视、听觉信号的记忆的机制的。     

老年人短时记忆特点的研究

本工作以50名青年作对照,对240名65—90岁正常老人的短时记忆特点进行了研究。结果看到:1.在逻辑故事记忆、图象自由回忆、数字广度和指向记忆四项记忆成绩上,均有随年老而衰退的明显趋势。其中除数字广度外,其他三项记忆在入老年后(65岁至90岁)有继续减退的趋势。在逻辑故事、指向记忆和总分上还见到有65岁和70岁组、75岁和80岁组成绩接近的现象;2.老年人顺背数字成绩较好,对刺激序列中末端刺激的正确回忆率较高,均说明老年人的初级记忆受损较少;3.四项记忆成绩比较,青年组故事分节分最高,然后依次为图象自由回忆、顺背数字和指向记忆,而老年组则无此明显顺序;4.文化因素对记忆成绩有明显影响。     

成人在错误信念任务上的表现

考察成人在错误信念(FB)任务上是否存在"知识偏差"效应。实验1重复Birch等的实验程序并未得到与之一致的结果,成人在FB任务上的表现不理想,且无"知识偏差"效应存在。实验2排除琴盒位置及颜色的突出性影响后,结果与实验1相似。成人在FB任务上的不佳表现与成人具有心理理论的事实相悖,说明把通过FB任务作为衡量心理理论的唯一评定标准有待商榷。     

Alteration of cingulate long-term plasticity and behavioral sensitization to inflammation by environmental enrichment

Exposure to an enriched environment (EE) has been shown to induce cortical plasticity. Considerable amount of research is focused on the effects of EE in the hippocampus; however, effects of EE on other brain regions and the mechanisms involved are not well known. To investigate this, we induced cortical plasticity by placing mice in an EE for one month and measured the effects of EE in the anterior cingulate cortex (ACC). Here, we show that EE enhanced the expression of the plasticity gene, egr-1, in the ACC of EE animals accompanied by enhanced cingulate long-term potentiation (LTP) and decreased cingulate long-term depression (LTD). The increased NMDA receptor NR2B/NR2A subunits current ratio is associated with the plasticity seen in the ACC while total protein levels remain unchanged. Furthermore, behavioral experiments show that these mice exposed to EE demonstrate enhanced responses to acute and long-term inflammation. Our findings suggest that exposure to EE alters physiological properties within the ACC which results in enhanced responses to inflammation.     

The role of ambiguity tolerance in career decision making

The role of ambiguity tolerance in career decision making was examined in a sample of college students (n = 275). Three hypotheses were proposed regarding the direct prediction of ambiguity tolerance on career indecision, the indirect prediction of ambiguity tolerance on career indecision through environmental and self explorations, and the moderation effect of ambiguity tolerance on the link of environmental and self explorations with career indecision. Results supported the significance of ambiguity tolerance with respect to career indecision, finding that it directly predicted general indecisiveness, dysfunctional beliefs, lack of information, and inconsistent information, and moderated the prediction of environmental exploration on inconsistent information. The implications of this study are discussed and suggestions for future research are provided.     

"人间佛教"的问题及都市佛教研究

20世纪初,太虚大师等人倡导的"人间佛教"运动警醒了明清至民国陷于腐败、堕落的中国佛教,开始了近一个世纪的"人间佛教"运动.进入新世纪,回头分析"人间佛教"的发展,可以从中吸取很多经验,同时也可发现当中存在的问题.笔者提出"都市佛教"理念,以期通过它为"人间佛教"的发展瓶颈找到解决之策.     

Sources of motivation, interpersonal conflict management styles, and leadership effectiveness: a structural model

126 leaders and 624 employees were sampled to test the relationship between sources of motivation and conflict management styles of leaders and how these variables influence effectiveness of leadership. Five sources of motivation measured by the Motivation Sources Inventory were tested-intrinsic process, instrumental, self-concept external, self-concept internal, and goal internalization. These sources of work motivation were associated with Rahim's modes of interpersonal conflict management-dominating, avoiding, obliging, complying, and integrating-and to perceived leadership effectiveness. A structural equation model tested leaders' conflict management styles and leadership effectiveness based upon different sources of work motivation. The model explained variance for obliging (65%), dominating (79%), avoiding (76%), and compromising (68%), but explained little variance for integrating (7%). The model explained only 28% of the variance in leader effectiveness.
