自闭症儿童对情景事件的情绪理解：基于内隐和外显的测量

该研究旨在采用生态效度更高的情绪情景事件以及内隐和外显两种测量方式考察自闭症儿童的情绪理解。选取自闭症和智商匹配的正常儿童各21名,以序列图片的方式呈现从动画片中截取的不同效价的情景事件,外显任务要求被试直接判断事件主角的情绪、内隐任务要求被试判断事件的一致性。结果发现：1.在外显任务中,自闭症儿童对正性和负性情绪的判断正确率均显著不如正常儿童,尤其是在负性情绪上存在明显的理解缺陷;2.在内隐任务中,正常儿童的正性负性情绪、自闭症儿童的正性情绪都表现出更弱的相对于中性情绪的理解效应;自闭症儿童的负性情绪理解则在两种任务中都接近于无。这些结果意味着自闭症儿童在外显和内隐任务中都存在负性情绪理解缺陷。     

当代客观化人格测验的技术—— 基于实验的行为评估:维也纳研究小组开发的多种计算机化测验介绍

目前多数人格测验(特别是在中国使用的人格测验)基本上都是人格问卷, 基于实验的行为评估类客观化人格测验应用很少; 而后者近来在德语圈国家中则有复苏的迹象。因此, 本文综述了此类客观测验相对于人格问卷来说所具有的特点和优势, 如, 被试很难在这类客观化人格测验中作伪。本文介绍了维也纳研究小组所做的几个测验, 并讨论了这些测验的心理测量学性质和缺点。最后, 还列举了这些测验的实际应用。     

Transverse diffusivity of cerebral parenchyma predicts visual tracking performance in relapsing–remitting multiple sclerosis

This study investigated the relation between cerebral damage related to multiple sclerosis (MS) and cognitive decline as determined by two classical mental tracking tests. Cerebral damage in 15 relapsing–remitting MS patients was measured by diffusion tensor imaging (DTI). Fractional anisotropy, longitudinal and transverse diffusivity were defined in the cerebral parenchyma. Cognitive performance of the MS patients was assessed with the oral response format of the Symbol Digit Modalities Test (SDMT) and the Paced Auditory Serial Addition Test (PASAT). A significant correlation was found between performance on the SDMT and the fractional anisotropy in the brain. This correlation was predominantly induced by transverse diffusivity. Transverse diffusivity refers to the diffusion across fibers rather than along the fibers and is believed to be a specific marker for axonal loss and demyelination associated with MS. No significant association between DTI-measures and PASAT performance was found and this negative finding was mainly attributed to psychometric qualities. These results indicate that diffusivity along the non-principal diffusion direction, a possible signature of MS-related white matter pathology, contributes to information processing speed as measured with the SDMT, a task that requires close visual tracking and a widely used clinical marker for cognitive decline in MS.     

企业员工工作伦理的结构

采用自行研制的工作伦理问卷, 通过对全国8个城市955名员工、6所高校508名在校大学生以及两大军区461名现役军人进行问卷调查, 对企业员工工作伦理的因素结构进行了探讨。探索性因素分析(n=478)表明, 企业员工工作伦理由职业操守、工作意义、勤奋奉献、积极进取和人际和谐5个维度构成。验证性因素分析(n=477)结果表明五因素模型是比较理想的模型。复核效化检验结果表明, 基于企业员工样本得到的工作伦理五因素结构在大学生样本(n=508)和军人样本(n=461)中具有一定程度的稳定性与预测力。文章最后对企业员工工作伦理维度的构成和内容进行了分析讨论。     

基于关系-表征复杂性模型的数学应用题表征能力测验

基于关系-表征复杂性模型,从每道应用题涉及集合关系的嵌套程度角度事前分析其关系复杂性,编制了难度序列变化的应用题测验,以考察问题表征能力。采用该测验测查了四至七年级共165名学生,考察事前分析的合理性及表征水平随年龄的变化。结果表明:(1)事前分析对两个事后难度指标(错误率和Rasch模型分析的任务难度)的解释率分别为73.7%、78.7%;该测验得分与测查思维水平层次变化的SOLO分类测验上的得分有较高相关(r=0.65)。(2)四年级的应用题表征水平显著低于五、六、七年级,其他三个年级差异不显著;而且随着问题关系复杂性的增加,年级差异增大。这说明基于关系-表征复杂性模型的事前分析是合理的,据此编制的测验能够测查表征水平随年龄的变化。     

脑电双频指数（BIS）对脊柱侧凸矫正术中唤醒时间的影响

探讨脑电双频指数（bispectral index,BIS）监测不同镇静深度对脊柱侧凸矫正术中唤醒时间的影响,60例行脊柱侧凸矫正手术的患者随机分为三组,Ⅰ组BIS30～40,Ⅱ组BIS40～50和Ⅲ组BIS50～60,评价各组患者的唤醒时间及不良事件发生率。结果显示Ⅰ组唤醒时间为（18．13±2．3）min,明显长于Ⅱ组和Ⅲ组的唤醒时间。而当BIS为40～50时,患者术中的不良事件发生率明显低于另外两组。所以,使用BIS进行全麻镇静深度的监测,在唤醒前将镇静深度维持在BIS40～50是合适的。     

The effect of development and individual differences in pointing comprehension of dogs

In spite of the rather different procedures actually used in comparative studies to test the ability of different species to rely on the human pointing gesture, there is no debate on the high performance of dogs in such tasks. Very little is known, however, on the course through which they acquire this ability or the probable factors influencing the process. Important developmental questions have remained unsolved and also some methodological concerns should be addressed before we can convincingly argue for one interpretation or another. In this study we tested 180 dogs of different age (from 2 months to adults) to investigate their performance in the human distal momentary pointing gesture. The results, analyzed at both the group and the individual levels, showed no difference in the performance according to age, indicating that in dogs the comprehension of the human pointing may require only very limited and rapid early learning to fully develop. Interestingly, neither the keeping conditions nor the time spent in active interaction with the owner, and not even some special (agility) training for using human visual cues, had significant effect on the success and explained individual differences. The performance of the dogs was rather stable over time: during the 20 trials within a session and even when subsamples of different age were repeatedly tested. Considering that in spite of the general success at the group level, more than half of the dogs were not successful at the individual level, we revealed alternative “decision-making rules” other than following the pointing gesture of the experimenter.

读者的元理解监测为什么不精确？

精确的元理解监测对随后的元理解控制和阅读理解有重要作用,但是,通常情况下,读者的元理解监测并不精确。回顾20余年的元理解监测研究,发现元理解监测的精确性主要受制于阅读材料特征、监测线索与标准测验特征等因素。未来研究应注意元理解监测的判断形式、监测线索及评价标准对元理解监测精确性的交互关联影响。     

内隐联想测验研究进展述评

内隐联想测验作为基于反应时范式的内隐社会认知研究方法,自1998年由Greenwald提出后,得到了广泛的应用。但因其本身具有一定局限性,近10年来,研究者们对这一方法进行了不断地修正和改进,先后发展出了GO／NO—GO联想任务、外部情感西蒙作业等;近几年又提出了单类内隐联想测验、单靶内隐联想测验和单属性内隐联想测验等,这些方法丰富充实了内隐联想测验,是对Greenwald提出的IAT的继承和发展。
