一种有神的信仰是怎样建立起来的(一)

这是一个真实的故事,也是一篇理论文章,有论有据、有血有肉,耐人寻味,引人深思,是一篇不可多得的好文章,望诸君能够跟踪本刊看完这个真实的故事。--编者     

任务难度对于返回抑制出现时间的影响

在返回抑制的范式下,以大学生为被斌,采用线索一靶子模式进行了两项实验.实施一发现,在觉察任务中,返回抑制在线索和靶子的时间间隔(SOA)为300ms时出现;在辨别任务中,返回抑制在SOA为700ms时出现.实验二发现在选择任务中,返回抑制在SOA为1300ms时出现.这些结果表明,随着实验任务的难度逐渐增大,返回抑制出现越来越晚.实验任务的难度是影响返回抑制出现时间的一个重要因素.     

短时记忆中的范畴组织和通道组织的比较

本文通过设置不同的线索条件对短时记忆中范畴组织和通道组织进行了比较研究。实验采用了通道线索组、范围线索组和混合线索组三种条件,并设置了五种词表比例。在通道线索组中,每个词表是同范畴字词,但一半用视觉呈现,一半用听觉呈现;在范畴线索组中,两类词分属两个不同的词义范畴,但以相同通道呈现;在混合线索组中,两类不同范畴的词,各有一半分别用视觉和听觉呈现。结果表明在三种线索条件下,ＡＲＣ分值差异显著,表现为     

不同作业阶段的分配注意对返回抑制的影响

在双作业条件下,利用线索－靶子模式进行了两个返回抑制实验,实验一应用简单分心刺激,实验二应用复杂分心刺激。两个实验均在呈现阶段或／和靶子呈现阶段安排分心作业,以大学生为被试,其主作业为觉察星号,尽快按键作出反应。结果表明：（１）在简单分心作业条件下,返回抑制依然存在,但数值减少,在复杂分心作业条件下,返回抑制全部消失。（２）无论分心作业如何,线索呈现阶段或／和靶子呈现阶段的分散注意对返回抑制所产生     

社群主义德性观

当代社群主义者在批评现代伦理理论误区的基础上论述了德性伦理,他们认为功利主义和康德主义义务论道德在相互论战中都忽视了人的德性的培育这一关键问题,因而需要复兴古典的德性,特别是亚里士多德所反复论述的德性.德性与幸福紧密相关,同时以理智和基于知识的正确选择为核心,而根本的德性是在两个极端之间取得中道,即中庸之道.公平、正义等不是绝对抽象的,它与人的理性选择和社会实践相关.这些论述对于人们认识现代社会所疏离了的德性,注意培育美德,特别是在民主制度下要求政治人物保持操守,坚守德行,防止腐败,都具有建设性的意义.当然,如何在现代多样化的社会复兴古典德性,防止停留于空幻的议论,真正实现德性践行上的进步,是社群主义者面对的一个理论难题.     

表象建构的面积评估

通过视觉或触觉给被试呈现完整的三角形,或呈现构成一个三角形所必要而又充分的一组部件以在表象上形成一个三角形,并评估其大小。结果发现,被试在表象中利用部件建构起来的三角形面积的增长,与实际知觉的三角形一样,均遵从幂函数定律,且幂函数指数均小于１,显示出表象与知觉的机能等价。     

Imputation methods for missing data in educational diagnostic evaluation

In the diagnostic evaluation of educational systems, self-reports are commonly used to collect data, both cognitive and orectic. For various reasons, in these self-reports, some of the students' data are frequently missing. The main goal of this research is to compare the performance of different imputation methods for missing data in the context of the evaluation of educational systems. On an empirical database of 5,000 subjects, 72 conditions were simulated: three levels of missing data, three types of loss mechanisms, and eight methods of imputation. The levels of missing data were 5%, 10%, and 20%. The loss mechanisms were set at: Missing completely at random, moderately conditioned, and strongly conditioned. The eight imputation methods used were: listwise deletion, replacement by the mean of the scale, by the item mean, the subject mean, the corrected subject mean, multiple regression, and Expectation-Maximization (EM) algorithm, with and without auxiliary variables. The results indicate that the recovery of the data is more accurate when using an appropriate combination of different methods of recovering lost data. When a case is incomplete, the mean of the subject works very well, whereas for completely lost data, multiple imputation with the EM algorithm is recommended. The use of this combination is especially recommended when data loss is greater and its loss mechanism is more conditioned. Lastly, the results are discussed, and some future lines of research are analyzed.     

Development of Genetic Counseling Services in Taiwan

Taiwan is an emerging industrial country in subtropical Asia with a population of 23 million. There were around 200,000 newborns in 2011. Delayed first marriage, low birth rate, and rapid aging are major demographic issues. Genetic counseling services were established following the rapid introduction of genetic technology and enactment of relevant laws and regulations. Ultrasound was first used in 1968 to examine pregnant women. The first amniotic fluid laboratory was founded in 1981 to identify chromosomal abnormalities. In 1984, the Genetic Health Act was legislated for prevention and control of genetic disorders, and the metabolic disorder screen project was launched. National Health Insurance with overall coverage of prenatal examinations was established in 1995. A master-level genetic counseling program was launched in 2003 and by 2011 has graduated eighty students. Two professional societies have been formed to certify genetic counselors, and 66 professionals have been certified. In summary, genetic counseling services in Taiwan are continuously improving.     

简明中学生心理素质量表(健康版)的修订及信效度研究

该研究在文献分析和理论研究的基础上,通过纵向研究与多轮横向研究考察原中学生心理素质量表的因子及题目与心理健康指标的关系,修订出了3维度12因子共36道题的简明中学生心理素质量表(健康版),包括元认知、目的性和开放性3因子的认知品质分量表,自信性、自控性和乐观性3因子的个性品质分量表,以及职业适应、社会适应、人际适应、情绪适应、学习适应和生理适应6因子的适应性(能力)分量表。修订后的量表与原量表总分之间的相关为0.939,其它项目分析、探索性因素分析、验证性因素分析、信度分析、效度分析等结果均达到了心理测量学的要求。     

农村流动人口的流动模式与其STD/HIV高危性行为的关系

本研究旨在探讨从农村到城市的流动人口的流动模式和高危性行为状况,分析流动模式与他们高危性行为的关系。根据流动人口的职业分布采取配额的方式从北京和南京两座城市共选取了有效被试4301名,其中北京2201名。评估了他们的流动性包括流动时间、流动城市和与性病/艾滋病(STD/HIV)有关的高危性行为包括发生性行为的时间、多个性伙伴和参与商业性行为状况、使用安全套状况。分析结果发现:(1)流动人口的流动性大,平均为0.77,男性、未婚的、年龄小于20岁的流动性比女性、已婚的和年龄大于20岁的显著大;(2)流动人口存在一定比例的高危性行为,男性和未婚的高危性行为显著多于女性和已婚的,尤其是安全套使用率低;(3)不同流动时间、流动城市和流动性的人在高危性行为有些显著差异,总的来说,流动时间越长、流动城市越多、流动性越大的人存在着更多的高危性行为。
