The place of words and numbers in psychiatric research

In recent decades, there has been widespread debate in the human and social sciences regarding the compatibility and the relative merits of quantitative and qualitative approaches in research. In psychiatry, depending on disciplines and traditions, objects of study can be represented either in words or using two types of mathematization. In the latter case, the use of mathematics in psychiatry is most often only local, as opposed to global as in the case of classical mechanics. Relationships between these objects of study can in turn be explored in three different ways: 1/ by a hermeneutic process, 2/ using statistics, the most frequent method in psychiatric research today, 3/ using equations, i.e. using mathematical relationships that are formal and deterministic. The 3 ways of representing entities (with language, locally with mathematics or globally with mathematics) and the 3 ways of expressing the relationships between entities (using hermeneutics, statistics or equations) can be combined in a cross-tabulation, and nearly all nine combinations can be described using examples. A typology of this nature may be useful in assessing which epistemological perspectives are currently dominant in a constantly evolving field such as psychiatry, and which other perspectives still need to be developed. It also contributes to undermining the overly simplistic and counterproductive beliefs that accompany the assumption of a Manichean “quantitative/qualitative” dichotomy. Systematic examination of this set of typologies could be useful in indicating new directions for future research beyond the quantitative/qualitative divide.     

融合反应时的多级评分IRT模型开发及其应用研究

当前大多数融合反应时的IRT模型仅适用于0-1评分数据资料,极大的限制了IRT反应时模型在实际中的应用。本文在传统的二级计分反应时IRT模型基础上,拟开发一种多级评分反应时模型。在层次建模框架下,分别采用拓广分部评分模型(GPCM)和对数正态模型构建融合反应时的多级评分IRT模型(本文记为JRT-GPCM),并采用全息贝叶斯MCMC算法实现新模型的参数估计。为验证新开发的JRT-GPCM模型的可行性及其在实践中的应用,本文开展了两项研究:研究1为模拟实验研究,研究2为新模型在大五人格-神经质分量表中的应用。研究1结果表明,JRT-GPCM模型的估计精度较高,且具有较好的稳健性。研究2表明,被试的潜在特质与作答速度具有一定的正相关,且本研究结果支持Ferrando和Lorenzo-Seva(2007)提出的“距离-困难度假设”,即当被试的潜在特质与项目的难度阈限距离越远,那么被试会花费更多的时间对项目进行作答。总之,本研究为拓展反应时信息在心理测量及教育中的应用提供新的方法支持。     

两例先天性无痛症患者的心理生理特点研究 Ⅱ.对致痛性强刺激的知觉和反应

本工作对两例先天性无痛症患者对于致痛性强刺激的知觉和反应进行了研究(例1女,10岁,例2男,13岁)。对照组为20例正常儿童,性别和年龄均与患儿相匹配。 结果:1),生活中痛:两例患儿均无(包括痛感觉和痛反应)。2)实验性痛:①痛感觉:两例患儿均无;②“痛”反应:例1有“痛”反应(脉搏和呼吸的变化以及行为反应明显,大致与正常儿童相似)。例2无“痛”反应(脉搏和呼吸的变化轻微,无行为反应,与正常儿童不同)。 由结果看来,先天性无痛症患者似乎可分为两种类型:不完全型(如同例1)和完全型(如同例2)。存在有“痛”反应而无痛感觉的无痛症患者。 本工作结果从另一侧面为痛的两成分学说提供了依据。

Timing at the Start of Associative Learning

Some theories of associative learning imply that time plays a fundamental role in the acquisition process. Consistent with these theories, this paper presents evidence that the time from the onset of a conditioned stimulus (CS) until presentation of the unconditioned stimulus (US) is learned very rapidly at the start of training. We report two autoshaping studies and a study on aversive conditioning in goldfish in which we examine timing at the start of conditioning. We also review data from a number of other conditioning preparations, including fear-potentiated startle, appetitive conditioning in rats, and eyeblink conditioning in rabbits, that report conditioned response (CR) timing early in training. Acquisition speed and the very first expressions of conditioned responding often show sensitivity to the time of US presentation. In instances where temporal control is slowly expressed, it is likely due to performance factors, not to slow learning about time. In fact, the learning about time may be a necessary condition for associative learning.     

Understanding families in their own context: schizophrenia and structural family therapy in Beijing

Evidence from a number of family intervention strategies demonstrates a beneficial impact on the course of schizophrenia. It appears that different family interventions have generic features that aid the patient to avoid relapse and improve functioning. A significant challenge for researchers is to modify these generic strategies to be sensitive to different cultural groups in order to ensure their effectiveness. Chinese culture, with its distinct cultural norms governing family interaction and intense stigma towards the mentally ill, would seem to raise a particular challenge.
This paper offers an account of an eclectic model of structural family therapy that incorporates psychoeducation and behavioural treatments for schizophrenia as a theoretical guide to working in a cross–cultural context. A Beijing family, consisting of parents and their daughter with schizophrenia, were seen for sixteen months during a trial of family intervention in China. Through structural family concepts, China's sociocultural context of treatment resource constraints, population policy and stigma are examined and the impact of the illness on family organization is explored.     

主体的复归与现象学的先验转向

现象学的先验转向是由意义自在转向先验主体,由完全悬置自我到复归主体,这一方面是由于观念自在论的种种困难所促成,另一方面主体主义哲学惟有通过先验转向才能克服其主观性悖论,先验观念论是主体主义哲学最后和最高的形式,而这种最高形式中也隐藏着先验主体的一些理论困难。     

培训迁移效果影响因素的初步研究

本研究通过访谈、问卷调查和现场研究等多种方法,考察了中学教师在接受一种新的教学方法培训后。组织气氛和个人特征对其迁移行为的影响。如果发现：(1)受训者对迁移气氛的知觉直接影响迁移行为发生的次数。(2)受训者对训练内容实用性的看法是影响迁移行为发生的重要环境因素,而受训者对训练内容实用性的看法会受到零反馈、自己的灵活性和自我效能的影响。(3)领导有无反馈、时间支持和同事支持等因素是区分培训迁移气氛类型的关键指标。
