Associations between sexual sensation seeking and AIDS-related knowledge,attitudes and behaviors among young men who have sex with men in China

Young men who have sex with men (YMSM) have become high risk groups for HIV infection in China. Recent researches suggest that sexual sensation seeking is significantly associated with AIDS-related knowledge, attitudes and behaviors, but the relationship is not clear in the field of YMSM in China. The present study aimed to evaluate the relationship between sexual sensation seeking and AIDS-related knowledge, attitudes, and behaviors among YMSM in China. A cross-sectional study was conducted in Wuhan, China from May to November 2013. 403 YMSM were recruited and 373 of them completed the questionnaire. Regression analyses indicated that YMSM with high sexual sensation seeking score are more likely to have low awareness of knowledge and negative attitude about condom use, as well as more risky sexual behaviors.     

Temporal and spectral dynamics underlying cognitive control modulated by task-irrelevant stimulus-response learning

Behavioral and recent neuroimaging findings have shown reversal of interference effects due to manipulating proportion congruency (PC), which suggests that task-irrelevant stimulus-response (S-R) associations are strengthened and applied to predict responses. However, it is unclear how the strengthened S-R associations are represented and applied in the brain. We investigated with a between-subjects PC paradigm of the Hedge and Marsh task using electroencephalography (EEG). The behavioral results showed the reversal of the conflict effects, suggesting that task-irrelevant S-R associations were strengthened and used to prepare responses. The EEG results revealed the PC-related reversal of the conflict effects in the frontocentral N2 and parietal P3b amplitudes. Time-frequency analyses showed more pronounced PC-related reversal of the conflict effects in theta band (4–8 Hz) activity in frontocentral sites. These results suggest that the strengthened S-R associations due to PC manipulation modulated cognitive control. Importantly, the amplitude of lateralized readiness potential was higher in the high-PC condition than in the low-PC condition, suggesting that the strengthened short-term-memory spatial S-R associations that modulated cognitive control were applied similarly to long-term-memory spatial S-R associations.     

意识特性的理论框架

G．M．Edelman和唐孝威在2003年初分别发表了关于意识特性理论框架的论文和专著。通过对两位学者提出的意识特性理论进行比较后发现,他们对脑功能活动机理以及神经信息加工的动态整合过程认识竟非常相近、对意识本质理论的描述也非常吻合。他们的研究表明了脑科学研究的物理学方向：随着脑成像技术的发展,从中可以获取丰富的脑神经信息,可以从系统层面上建立表征脑复杂性的数学物理模型,辨识脑神经各部分之间的关联作用,研究脑神经信息的整合过程。     

哈贝马斯在汉语世界的历史效果--以《公共领域的结构转型》为例

本文的着眼点不是全面而系统地梳理哈贝马斯在汉语学界被接受的历史过程,而是试图以哈贝马斯的代表作《公共领域的结构转型》作为范例,通过该书在汉语学界近十年来的接受、研究与应用,来阐述哈贝马斯在汉语世界的历史效果,并试图为建立哈贝马斯与汉语世界之间的良性互动关系寻找途径。     

分类的样例观及其研究进展

分类研究近年来已成为认知科学研究的一个重点,样例观是基于相似性表征的,自从产生以来获得了很大发展。该文对于样例观及其近年来出现的样例模型进行了比较全面的介绍,然后介绍了心理学界针对样例观的争论,最后提出各种分类模型的整合是未来样例观的发展趋势。     

Adaptation of the Wechsler Intelligence Scale for Children-IV (WISC-IV) for Vietnam

Intelligence testing is used for many purposes including identification of children for proper educational placement (e.g., children with learning disabilities, or intellectually gifted students), and to guide education by identifying cognitive strengths and weaknesses so that teachers can adapt their instructional style to students’ specific learning styles. Most of the research involving intelligence tests has been conducted in highly developed Western countries Yet the need for intelligence testing is as or even more important in developing countries. The present study, conducted through the Vietnam National University Clinical Psychology CRISP Center, focused on the cultural adaptation of the WISC-IV intelligence test for Vietnam. We report on (a) the adaptation process including the translation, cultural analysis and modifications involved in adaptation, (b) present results of two pilot studies, and (c) describe collection of the standardization sample and results of analyses with the standardization sample, with the goal of sharing our experience with other researchers who may be involved in or interested in adapting or developing IQ tests for non-Western, non-English speaking cultures.     

从科学发展的维度看邪教问题

科学与邪教都是人类社会中存在的复杂现象,两者之间的关系也是非常复杂的。从本质上看,科学发展与邪教是对立的。从表现形态看,科学发展状况与邪教并非完全对立。科学发展带来的许多方面的社会后果,有些有利于对邪教的防范与抵制,有些则可以为邪教的产生和流传提供各种不同的空间。要防范抵制邪教,应该大力发展和普及科学、培养科学的想象力、守卫好科学的边界等等。     

高中生学习策略调查研究

用自编量表调查了一所重点高中和一所普通高中2658名学生的学习策略状况。因素分析结果显示:高中生学习策略可用一个三层次结构的图式表征,最概括的顶层为主导性和辅助性两大策略群;中间层次为学习态度调整、学习行为管理、学习方法运用、学习环境适应、课外活动调控等五大策略亚群;基层次为良好的学习心态,积极合理规划学习生活,预习和复习总结,营造学习的人际环境,劳逸结合、丰富课余生活等19项策略子群。重点高中学生、成绩好的学生、年级高的学生,在主导性策略方面存在优势,主要体现在学习态度调整和学习方法运用这2个策略亚群上。在学习策略的性别差异上,男生更善于营造学习的人际环境、运用学习行为管理方面的策略,而女生则更注重学习方法运用的策略。     

Use of three depression scales for evaluation of pretreatment severity and of improvement after treatment

We investigated the Castilian Spanish versions of three scales (the Hamilton Rating Scale for Depression, the Carroll Rating Scale for Depression, and the Montgomery-Asberg Depression Rating Scale) as to their suitability for classifying major depression patients in four levels of severity prior to treatment with tricyclic antidepressants, and also as to their suitability for classifying these patients in four improvement levels when administered posttreatment. Although the scales behaved quite similarly, each was most efficient at the task for which it had been designed, i.e., severity rating for the Hamilton and Carroll scales, improvement rating for the Montgomery-Asberg scale.
