试论心身疾病的中医病机

心身疾病是指那些心理-社会因素在疾病的发生和发展中起重要作用的躯体疾病.其概念决定了心身疾病不具有专业领域性,不同心身疾病有着不同的病理变化.发掘其病理共性、找寻规律性,对该学科发展的标准化方向至关重要.该文从中医基本病机层次,探讨了心身疾病的发生、发展与变化的机理,试图对科研与临床操作提供有益思路.     

人格测量：从累积式模型到展开式模型

当前大多数人格测量都采用的是累积式反应模型方法,该模型假设被试在测验上的得分随其能力或特质提高而增加,但是随着人格测量技术的不断发展,这一模型的实施效果遭到了质疑,研究者们开始关注展开式模型,该模型认为被试的反应取决于被试能力和项目阈值的匹配程度,当被试能力与项目阈值完全匹配时,被试做出肯定回答的概率达到最高点,称之为“理想点”,展开式模型的目的就是找到被试的理想点,从而寻找其真正的态度强度或人格特质水平。GGUM作为一种比较成熟的展开式模型,已经开始应用于人格测量的各个领域,但仍需要进行大规模的试测,在评估和预测效度方面积累经验,建立业界认可的心理测量学标准,不断探讨和开发相应的心理测量理论和简便易行的统计程序。     

正当与德性的分离 ——康德在伦理学主题现代转向中的作用

随着伦理学的发展,伦理学的主题发生了现代转向:从以"善"为核心的德性伦理学逐渐向以"正当"为核心的现代道德哲学转变,其中康德的伦理学在此次转向中起着重要作用,成为联系传统的德性伦理学和现代道德哲学的关键环节。     

The association between self-deception and moral self-concept as functions of self-consciousness

Regulated by self-consciousness, self-deception is a part of the self-system that suppresses negative aspects of the self and maintains a positive moral self-concept. We tested this evolutionary hypothesis on 166 college students by measuring self-deception using both a questionnaire and a series of hypothetical helping scenarios. The results showed a positive correlation between self-deception and moral self-concept, which was moderated by private self-consciousness. Among participants with high, but not low, self-consciousness, high moral self-concept individuals were more willing to help when potential self-benefits were present than low moral self-concept individuals, whereas there was no difference between the two groups concerning helping without self-benefit. These results support the evolutionary view that self-deception serves to maintain optimal moral self-concept, especially for individuals with high self-consciousness.     

脑功能成像的新方法——功能性近红外光谱技术（fNIRS）

功能性近红外光谱技术（functional near-infrared spectroscopy, fNIRS）利用血液的主要成分对600-900nm近红外光良好的散射性,从而获得大脑活动时氧合血红蛋白和脱氧血红蛋白的变化情况。目前该技术开始运用于自然情境下的高级认知、发展心理学、异常心理学等多个领域的研究。该技术具有造价较低、便携性好,无噪音、无创性和对实验过程中被试动作不会过份敏感等优点,但也存在空间分辨率不高和校正算法有待进一步完善等方面的不足。未来fNIRS的研究可以与fMRI等其他成像技术进行结合,开展婴幼儿和特殊人群的认知神经科学研究以及自然情境下大脑认知的神经机制研究。     

如何唤起和缓解重大损失情绪—— 来自行为和脑成像的证据

本研究在没有真实伤害的情况下研究重大损失情绪及相应的脑机制。通过一系列行为和脑成像实验, 研究者们摸索出了可靠诱发重大损失情绪的范式, 并从对比效应和金钱补偿角度初步探讨了缓解这种情绪的方法。研究发现, 由于自我防御机制的存在, 抑制了被迫接受条件下重大损失情绪的唤起, 但却成功唤起了被迫选择条件下重大损失的情绪。此外, 研究还发现, 金钱补偿和对比效应都是缓解重大损失情绪的有效策略。本研究不仅有利于认识重大损失情绪的信息加工机制, 而且也为涉及重大损失情绪的心理咨询和保险理赔制度等提供了行为和脑成像证据。     

汉语同音字具体频率和同音字数在听觉词汇通达中的相互作用

用跨通道的音-字同音判断任务配以视觉词汇判断作协变分析,实验研究了汉语同音字音节的听觉词汇通达中同音字具体频率和同音字数的相互作用,等同了音节的累积频率和笔画数,结果发现了稳健的同音字族内的词频效应,同音字数与同音字频率相互牵制,表现在同音字数效应缺失,两因素刺激材料难以完全控制新的影响因素产生,出现逆抑制效应。结果说明在同音字频率和同音字数的相互作用中频率起稳健和主导的作用。     

大学生自我怜悯问卷的修订及信效度研究

目的:对Neff编制的自我怜悯量表进行修订和信效度检验。方法:总共对440名大学生进行了问卷预测与正式测验,使用SPSS13.0和LISREL8.70软件对数据进行分析。结果:①修订后的量表包含6个维度、26个条目。②各维度和量表的同质信度在0.64-0.87之间;探索性因素分析表明各条目对所属因子有中度以上的负荷,抽取的6个因子解释了总方差的55.09%。验证性因素分析的拟合优度指数、相对拟合优度指数、非标准化拟合优度指数为0.85-0.94,近似误差均方根为0.059。结论:大学生自我怜悯量表的信效度符合心理测量学要求。     

Normative data on a battery of neuropsychological tests in the Han Chinese population

In order to develop normative data of a battery of neuropsychological tests in the mainland Chinese population, we examined the performance of 15 neuropsychological tests in 465 healthy subjects (231 males and 234 females) in a population‐based cohort study. The years of education were ranged between 1 and 23 years, and ages were ranged between 16 and 75 years old. The 15 neuropsychological tests cover five domains of neurocognitive functions including attention and speed of information processing, memory and learning, verbal function, visual constructive abilities, and executive function. We also assessed the effects of gender, age, educational attainment on the performance of these neuropsychological tests. The results showed that, as expected, educational attainment and age are the two main factors affecting performance in these tests. Educational attainment has the strongest predictive effect on all tests, while the majority of tests selected in this study are also affected by age at examination to varying degrees. The presented normative data will be useful for future studies in related clinical research, and be of value in transcultural neuropsychological studies.     

Flexibility of theory of mind in a matrix game when partner's level is different

The development of theory of mind (ToM) was investigated as flexibility of prediction and decision-making in matrix games with 202 13-, 16-, 19-, and 24-year-old participants. The ToM flexibility of prediction and decision-making showed no significant differences among any age group. The ToM flexibility of prediction and decision-making of the 0th-order partner was better than that of the 1st-order partner. The ToM flexibility of prediction was better than the ToM flexibility of decision making. Matrix games are a feasible, effective, and discriminative way to explore higher levels of theory of mind.
