数字式肌电显示仪及其在体育中的应用

本文介绍数字式肌电显示仪。由微电极检测得到的肌电信号经过放大器之后被本仪器以数字形式显示出来,由于其具有对输出量的保持以及提供不同的展示肌电值的时间间隔的功能,它可以用于估计和分析人体的紧张程度。本仪器已用于国家射击队的心理训练。     

字符的知觉表征及其启动

实验以英文单词,汉字和图片为材料,采用速示补笔测验测量了大脑左右半球的启动效应。结果是,如果学习与测验的字体和大小不变,则视觉启动右半球高于左半球。其他材料不产生这种效应。这表明,至少有一个分离的系统对构成启动的汉字的视觉表征进行编码,此系统在右半球表征形状特异形状特异信息更有效;对字符抽象特征的表征,两半球无显著差异,速示补笔测量的是前语义水平的知觉表征,是一种知觉（数据驱动）内隐记忆测验。     

基于语义的词汇判断的计算模型

词汇判断是一种在字词认知研究中广泛使用的实验范式。本文提出了一个基于分布式语义表征的计算模型,用来解释某些在词汇判断作业中出现的实验现象。模型是一个包括词形层、隐层、语义层、词典层和判断层的前传网络。词形层、隐层和语义层之间的连接权重在学习过程中被不断调整,使用反传算法进行学习。语义层、词典层和判断层之间的连接权重在学习前就已被固定,在学习过程中不进行调整。模型模拟了在词汇判断作业中出现的四种实验现象：（１）频率效应;（２）语义启动效应;（３）频率与语境的交互作用;（４）重复启动效应。模型所表现出的行为特性由模型的框架和学习算法所决定。     

差数显著性t检验与元分析的对比研究

利用计算机构造被试总体、模拟实验研究程序进行抽样研究,探讨显著性ｔ检验方法与元分析方法在检验实验结果数据方面的差异。在模拟实验过程中,ｔ验受到显著性水平、样本容量和总体效果大小的影响,因此最终影响了统计推断的可靠性,建议：在进行显著性检验过程中,应对统计检验能力进行估计;元分析方法以样本为元素对总体进行推断,因此具有很高的准确性和可靠性,它将很有可能成为今后心理学研究的重要统计工具。     

生物反馈、肌肉放松与高血压

本文旨在了解生物反馈与高血压病的关系,以临床客观指标探索它们之间的差量。随意选择高血压病者39名,分为三个组:单纯生物反馈组,肌肉放松训练组以及生物反馈辅助肌肉放松训练组。经一个月训练结果表明:单纯生物反馈组收缩压与舒张压的疗效有非常显著性差异水平。肌肉放松组仅收缩压疗效有统计学意义,舒张压不呈现差异水平。生物反馈辅助肌肉放松训练组两种血压疗效与单纯生物反馈组类似。这说明单纯生物反馈在治疗高血压中起主要作用。肌肉放松有很强的局限性。     

Rheumatoid arthritis is associated with negatively variable impacts on domains of female sexual function: evidence from a systematic review and meta-analysis

To systematically review the literature to identify the impact of rheumatoid arthritis (RA) on specific female sexual function domains. A meta-analysis was performed and the related literature were searched in MEDLINE, EMBASE, Cochrane Library, CNKI, CBM and Web of Science databases, and in reference lists of articles and systematic reviews. Score of the Female Sexual Function Index (FSFI) was used as the outcome measurement, and mean differences (MD) with 95% confidence intervals (CI) were calculated. Five studies were included, including 346 women with RA and 237 healthy female controls. Each domain of the FSFI score: lubrication (MD, ?2.48; 95% CI, ?3.69, ?1.28), orgasm-1.71 (?2.09, ?1.33), sexual desire-1.27 (?1.59, ?0.95), satisfaction-1.67 (?2.18, ?1.16), arousal-1.83 (?2.85, ?0.82), pain-1.57 (?2.43, ?0.70) and the total score ?8.84 (?11.88, ?5.79) were lower in RA women than healthy controls. Furthermore, lubrication dimension was most severely affected especially. This meta-analysis showed that female RA patients scored lower in each dimension of FSFI, mostly in the lubrication domain. It demonstrated that targeted interventions should be done to improve their sexual function. Future well-designed researches with larger sample sizes are necessary to evaluate the potential risk factors which determine female sexual dysfunction.     

Time perspective,optimistic bias,and self-control among different statuses of university smokers in China: a cross-sectional study

Risk behavior often seems ‘self-defeating’ to the observers. Most people understand the basic health-related knowledge, but some of them still choose to continue risk behaviors, especially for the young. This study aimed to examine time perspective, optimism bias and self control correlated with smoking behavior in Chinese college students. A cross-sectional survey enrolling 3016 university students in Chengdu City, Sichuan Province, China. Influence Factors were identified using multiple logistic regression analyses. Prevalence of current smoking was 20.92% (631 smokers), including 272 daily smokers (9.02%) and 359 non-daily smokers (11.90%). Future-oriented time perspective, general capacity for self-discipline, reliability and ethnicity were protective factors of smoking behavior. Possibility of self-suffering diseases and gender were risk factors of smoking behavior. Smoking in University of Chengdu, China is a severe problem. Results in this research have suggested that irrespective of the smoking level, improving health-related knowledge, time management awareness and self-control ability may contribute to reducing the prevalence of smoking behavior.     

特殊信任视野中的公民法治观念——基于两次延续性调查的研究视角

在人类社会的早期,信任问题就已经被人们所关注,无论是中国的先秦还是西方的古希腊,都有关于信任方面的大量论述。但是,人类早期关于信任的认识只是表面的、零星的,并没有深入细致的探讨。20世纪开始,人们才对信任问题进行了专门化、系统化的研究和论述。信任作为一种重要的社会资本,在与人力资本、金融资本等推动经济发展的同时,更显示出了其重要的政治功能。信任是现代民主制度建立的基础,更是维系政治稳定的粘合剂。自古以来民主和法治形影不离,而信任是否也会对与民主政治紧密相连的公民法治观念产生影响呢?本研究以南京市的实证调查为例,通过多元回归分析等统计分析方法,对特殊信任与公民法治观念之间的关联性进行实证层面的剖析,并对如何提高公民的普遍信任度从而培育公民法治观念进行反思和展望。     

反馈对注意缺损多动障碍儿童错误监控能力的影响

研究选取了注意缺损多动障碍(ADHD)儿童39名,正常儿童40名,采用两项选择任务,考察在无反馈和有反馈的情况下,ADHD儿童的错误监控能力是否存在缺损。结果发现,(1)无论是否提供反馈,与正常儿童相比,ADHD儿童的错误察觉能力正常,但是错误更正能力落后,这可能是由于ADHD儿童动作调节控制能力落后导致的;(2)反馈提高了ADHD儿童和正常儿童的认知加工速度,但同时降低了他们的警醒水平,导致错误监控能力下降。     

急性脑梗塞患者CD_18、CD_54与CD_62p、CD_63表达变化的临床研究

为探讨粘附分子CD18、CD54和血小板CD62、CD63表达变化与急性脑梗塞（ACI）发病之间的关系,本文应用流式细胞仪（FCM）检测了52例ACI患者治疗前后CD18、CD54与CD62p、CD63两者的表达水平,并与30例正常人作对照。结果显示,脑梗塞组治疗前两者的表达水平均明显上调,与正常对照组比较均有显著差异...
