德性伦理与规范伦理在生命伦理中的契合

在生命伦理领域中,规范伦理与德性伦理都曾发挥重要作用,然而,德性伦理没有受到人们足够的重视,重新厘定传统德性伦理的现代价值显得尤为重要。初步探究在生命伦理迅速发展的情况下,德性伦理与规范伦理相结合的模式。     

Malleability of attitudes or malleability of the IAT?

In the current set of experiments, we establish, and explore the consequences of, the imprecision that characterizes the attribute response labels typically employed in the Implicit Association Test (IAT). In Experiment 1, we demonstrate the malleability of the IAT, as conventionally implemented. IAT scores are shown to be influenced by perspective mindsets induced by an unrelated preceding task. Then, we explore how the malleability of the IAT can lead to the inference that attitude change has occurred even when there is very good reason to believe it has not (Experiment 2), and conversely, how it can obscure the detection of attitude change when such change is indeed likely to have occurred (Experiment 3). We provide conceptual explanations for these discrepancies and suggest methodological improvements to enhance the specificity of IAT measures.     

生长激素对心血管系统的影响

生长激素（GH）是出生后主要刺激生长的激素,GH相当高比例的促生长作用是由胰岛素样生长因子-I（IGF—I）介导完成的。不同的代谢功能如碳水化合物和脂类代谢也受GH的直接影响。GH还对心血管及大脑有影响,本文拟对其分泌机制及作用和对心血管及大脑的影响作一综述。     

自我损耗：理论、影响因素及研究走向

自我的活动消耗心理能量后引起执行功能下降的过程称为自我损耗, 自我损耗是生活中诸多的适应不良现象的原因之一。近几年, 自我损耗理论在发生领域、损耗状态的时限和内在机制等方面均有所发展; 对自我损耗影响因素的探究主要集中于认知、情绪及人格特质等领域; 自我损耗后效的研究逐渐呈现出应用化的趋势。未来研究需要进一步探究自我损耗的机制, 对影响因素和损耗后效上存在的争议进行澄清, 并在测量工具上寻找突破以满足理论的发展需求。     

A phase transition model for the speed-accuracy trade-off in response time experiments

Most models of response time (RT) in elementary cognitive tasks implicitly assume that the speed-accuracy trade-off is continuous: When payoffs or instructions gradually increase the level of speed stress, people are assumed to gradually sacrifice response accuracy in exchange for gradual increases in response speed. This trade-off presumably operates over the entire range from accurate but slow responding to fast but chance-level responding (i.e., guessing). In this article, we challenge the assumption of continuity and propose a phase transition model for RTs and accuracy. Analogous to the fast guess model (Ollman, 1966), our model postulates two modes of processing: a guess mode and a stimulus-controlled mode. From catastrophe theory, we derive two important predictions that allow us to test our model against the fast guess model and against the popular class of sequential sampling models. The first prediction--hysteresis in the transitions between guessing and stimulus-controlled behavior--was confirmed in an experiment that gradually changed the reward for speed versus accuracy. The second prediction--bimodal RT distributions--was confirmed in an experiment that required participants to respond in a way that is intermediate between guessing and accurate responding.     

不同车速下司机对交通标志的辨认距离实验

本实验所得数据表明,不同车速下司机对同一标志的判读距离是不一样的,车速愈高,司机能判读标志的距离就愈短,同步行时相比,在车速提高到100公里/小时时,司机对标志的判读距离可减低35～45％。据我们的补充实验,这种现象的产生可能是由于司机在高速驾车情况下所产生的生理心理负荷造成的。     

汉字识别中部件的频率效应

用整字识别、整合识别和部件识别任务探讨部件频率在汉字显示识别中的作用．实验一发现第一部件频率促进低频两部件合体字识别;实验二先后呈现合体字两组成部件并识别整字,第二部件频率有干扰作用;实验三识别合体字中的部件,部件频率有易化作用．部件在汉字识别中的易化和干扰作用受整字频率和结构类型的影响．     

江西武宁太平山佑圣宫

南昌大学江右哲学中心成立了"江西道教史"课题组,笔者有幸参加.因课题研究需要,本人于2007年8月1日至19日在江西各地考察道教宫观,先后考察了南昌青云谱、太平山佑圣宫、景德镇斗姥宫、贵溪鬼谷洞道院、萍乡横龙洞道院、武功山紫极宫和白鹤峰道观、会昌翠竹祠、赣州玉虚观、宁都翠微峰的金精洞碧虚宫、云台峰云台宫、普道岩紫微宫.其中太平山佑圣宫由于供奉有南宋道士章哲的肉身,是最引人注目的一处宫观.
