为什么要有道德

"为什么要有道德"是伦理学的基本问题.这个问题可以分为社会为什么要有道德和个人为什么要有道德.经过分析我们发现,后面一个问题原来是无解的.这样,与其追问有道德的目的不如探究有道德的原因,以及有道德的后果,这些都有助于我们重新思考道德教育和道德进步.     

Beyond risk and ambiguity: Deciding under ignorance

In this study, we examined the neural basis of decision making under different types of uncertainty that involve missing information: ambiguity (vague probabilities) and sample space ignorance (SSI; unknown outcomes). fMRI revealed that these two different types of uncertainty recruit distinct neural substrates: Ambiguity recruits the left insula, whereas SSI recruits the anterior cingulate cortex, bilateral inferior parietal cortex, and the lateral orbitofrontal cortex. The finding of unique activations for different types of uncertainty may not necessarily be predicted within the reductive approach of modern theories of decision making under uncertainty, because these theories purport that humans reduce more complicated uncertain environments to subjectively formed less complicated ones (i.e., SSI to ambiguity). The predictions of the reductive view held only for ambiguityaverse individuals and not for ambiguity-tolerant individuals. Consequently, theories of decision making under uncertainty should include individual tolerance for missing information and how these individual differences modulate the neural systems engaged during decision making.

Position of phonetic components may influence how written words are processed in the brain: Evidence from Chinese phonetic compound pronunciation

Previous studies have shown a right-visual-field (RVF)/left-hemisphere (LH) advantage in Chinese phonetic compound pronunciation. Here, we contrast the processing of two phonetic compound types: a dominant structure in which a semantic component appears on the left and a phonetic component on the right (SP characters), and a minority structure with the opposite arrangement (PS characters). We show that this RVF/LH advantage was observed only in SP character pronunciation, but not in PS character pronunciation. This result suggests that SP character processing is more LH lateralized than is PS character processing and is consistent with corresponding ERP N170 data. This effect may be due to the dominance of SP characters in the lexicon, which makes readers opt to obtain phonological information from the right of the characters. This study thus shows that the overall information distribution of word components in the lexicon may influence how written words are processed in the brain.

人格特质与主观幸福感:情绪调节的中介作用

通过对1163名大学生被试进行人格特质、情绪调节策略的使用以及主观幸福感的测查,本研究探讨了气质性人格特质(神经质和外倾性)这种稳定的内在心理结构对主观幸福感产生影响的可能机制。结果发现:(1)除直接影响个体的主观幸福感外,神经质和外倾性还会通过重新评价策略的使用间接影响主观幸福感;(2)人格特质和重新评价策略的使用可以有效预测个体主观幸福感的变异;(3)习惯性地使用表达抑制策略对个体的主观幸福感并没有显著的影响。这些结果表明重新评价策略的使用在人格特质对主观幸福感的影响中具有重要的中介作用。该发现对进一步制定改善和提高个体的主观幸福感的干预措施具有重要的启示和指导意义。     

罪犯精神病态的初步探索

以中国罪犯为被试,对Hare精神病态量表进行修订,并在此基础上进一步探讨罪犯精神病态的影响因素。研究结果表明:(1)修订的Hare精神病态量表具有良好的信度和效度;(2)年龄、文化程度、婚姻状况和犯罪次数是影响罪犯精神病态得分的重要因素。20-29岁年龄组罪犯精神病态的得分显著高于30-38岁年龄组;文化程度高的罪犯精神病态的得分显著低于文化程度低的罪犯,大专以上文化程度的罪犯精神病态得分最低;未婚罪犯精神病态的得分显著高于已婚和离异的罪犯;累犯精神病态的得分显著高于初犯。     

资本市场中投资者羊群行为的心理机制及其影响因素

资本市场中投资者的羊群行为是资本市场上的一种典型现象,它是指在不确定情境中,投资者在相同时间段内模仿他人进行投资决策的行为。通过比较羊群行为与从众行为发现,两者存在本质区别。目前,大量研究从社会影响、认知机制以及进化机制三个方面深入分析羊群行为的形成原因。此外,研究还发现,情境的不确定性、市场环境、群体内部一致性程度、个体的情绪与动机对投资者的羊群行为都会产生一定的影响。在总结相关研究后发现,羊群行为具有其自身独特的信息加工模式。未来关于羊群行为的研究应该从探索专家羊群行为的信息加工方式,提高研究的外部效度,探索认知神经机制,进行跨文化研究和探讨羊群行为与人格之间的关系等五个方面展开。     

企业员工工作倦怠研究:归因的视角

运用问卷调查法从归因视角对企业员工工作倦怠进行探讨,结果表明:(1)采用安戈夫(Angof)f方法得到倦怠标准的界定分数,其中情绪耗竭维度为21分,玩世不恭维度为14分,成就感低落维度为19分;(2)归因的物质环境、人际关系与价值感因子均与情绪耗竭、玩世不恭呈显著正相关,与成就感低落呈显著负相关,而归因的生活态度因子仅与个人成就感低落呈显著负相关;(3)人际关系与价值感因子对情绪耗竭有显著的正向预测作用;价值感因子对玩世不恭有显著的正向预测作用;物质环境与生活态度因子对成就感低落有显著的负向预测作用。

东北地区高师院校师范生教师职业成熟度的现状

采用自编师范生教师职业成熟度问卷对东北地区6所高师院校师范生进行了师范生教师职业成熟度发展现状的调查。结果表明：（1）在教师职业能力成熟度方面,师范生表现为知识准备比较充分,但有关教师专业技能的社会实践经验不足;（2）师范生教师职业成熟度的发展水平随着年级的增长而递增;（3）女生的师范生教师职业成熟度显著高于男生,农村学生显著高于县镇和城市学生,并且省属普通高师院校师范生比省属重点高师院校师范生做了更充分的教师职业能力准备。
