一般流体智力研究中工作记忆与注意的关系

随着对一般流体智力的研究逐步深入,研究者们认为了解工作记忆与注意的相互关系是解决一般流体智力与前二者结构关系的关键。由于工作记忆系统中中央执行器的功能尚不明确,注意控制能力与工作记忆的关系难以确定。研究者中存在两种不同的观点：一种认为两者之间存在着密切的互动,另一种则认为两者就是同功同构的一个认知成分。     

螺旋CT双期增强薄层扫描对小胰腺癌诊断的研究

为了研究螺旋CT胰腺期、肝脏期双期增强薄层扫描在小胰腺癌早期诊断中的作用,对25例小胰腺癌患者行螺旋CT双期增强扫描,结果显示,两组观察结果经统计学处理有显著性差异,螺旋CT动态增强薄层2mm扫描比5mm扫描可明显提高小胰腺癌和微胰腺癌的检出率,对小胰腺癌的早期诊断有重要的临床价值。肝脏期扫描为临床确定肿瘤是否能够手术切除提供科学依据。     

社会文化震荡中幽默应对的机制

应对社会文化震荡需要社会性的宏观策略,更需要适宜的微观策略--个体的自我调节策略.幽默感本质上是认知、情绪、行为、心理和社会等各方面的整合.幽默感的本质决定了幽默对个体从接受刺激到做出反应的各个环节都具有调节作用,能满足社会文化震荡中个体超越各种障碍时的心理调节需要和行为需要.本文通过介绍国外的研究成果,阐释了幽默作用于社会文化震荡的四个机制:认知中心机制、情绪中心机制、问题中心机制和结果接受机制.     

A cross-culturally standardized set of pictures for younger and older adults: American and Chinese norms for name agreement,concept agreement,and familiarity

The present study presents normative measures for 260 line drawings of everyday objects, found in Snodgrass and Vanderwart (1980), viewed by individuals in China and the United States. Within each cultural group, name agreement, concept agreement, and familiarity measures were obtained separately for younger adults and older adults. For a subset of 57 pictures (22%), there was equivalence in both name agreement and concept agreement, and for an additional subset of 29 pictures (11%), there was nonequivalent name agreement but equivalent concept agreement, across all culture-by-age groups. The data indicate substantial differences across culture-by-age groups in name agreement percentages and number of distinct name responses provided. We discovered significant differences between older and younger American adults in both name agreement percentages (67 pictures, or 26%) and concept agreement percentages (44 pictures, or 17%). Written naming responses collected for the entire set of Snodgrass and Vanderwart pictures showed shifts in both naming and concept agreement percentages over the intervening decades: Although correlations in name agreement were strong (r = .71,p < .001) between our younger American samples and those of Snodgrass and Vanderwart, name agreement percentages have changed for a substantial proportion (33%) of the 260 pictures; moreover, 63% of the stimuli for which Snodgrass and Vanderwart reported concept agreement now appear to differ. We provide comprehensive comparison statistics and tests for both the present study and prior ones, finding differences across numerous item-level measures. The corpus of data suggests that substantial differences in all measures can be found across age as well as culture, so that unequivocal conclusions with respect to cross-cultural or age-related differences in cognition can be made only when appropriate stimuli are selected for studies. Data for all 260 pictures, for each of the four groups, and all supporting materials and tests are freely archived athttp://agingmind.cns.uiuc.edu/Pict Norms.

重大突发事件下价值观与幸福感的变化:基于潜变量增长和交叉滞后模型

对1495名被试的价值观与幸福感进行了三个时间点的追踪研究,通过潜变量增长模型和交叉滞后回归模型,考察重大突发事件下价值观与幸福感的变化及其相互作用。结果发现:(1)T1到T3民众的自我超越价值观显著下降,保守和开放价值观显著上升;(2)T2到T3民众的幸福感显著下降;(3)T2自我超越价值观正向预测T3幸福感,T2自我增强价值观负向预测T3幸福感;(4)T2幸福感正向预测T3自我超越和保守价值观,负向预测T3自我增强和开放价值观。该结果为今后重大突发事件下的价值观引导提供了实证依据。     

子宫内膜异位症导致不孕机理探讨

近年来的研究表明了EMT和不孕之间存在较强的相关性,但是两者之间的因果关系和发病机制目前仍存在争议。本文对子宫内膜异位症与不孕之间机理探讨是从分析和综合相结合的认识方法来达到掌握两者关系的本质及其规律性的目的。遵循这样科学的发展战略才能更有利于人类医学领域的繁荣发展。     

Lay rationalism and inconsistency between predicted experience and decision

Decision‐makers are sometimes depicted as impulsive and overly influenced by ‘hot’, affective factors. The present research suggests that decision‐makers may be too ‘cold’ and overly focus on rationalistic attributes, such as economic values, quantitative specifications, and functions. In support of this proposition, we find a systematic inconsistency between predicted experience and decision. That is, people are more likely to favor a rationalistically‐superior option when they make a decision than when they predict experience. We discuss how this work contributes to research on predicted and decision utilities; we also discuss when decision‐makers overweight hot factors and when they overweight cold factors.

大学生安全感对手机成瘾的影响:回避现实社交的中介作用

为有效预防和干预大学生的手机成瘾，本研究在失补偿假说的视角下探讨了安全感与手机依赖的关系，并检验现实社交回避在手机成瘾者和一般手机使用者中的中介作用。对420名在校大学生进行安全感量表、社交回避与苦恼量表、手机成瘾指数量表调查，结果发现此次调查中49.8%的大学生被界定为手机成瘾者，手机成瘾者的安全感显著低于一般手机使用者。手机成瘾者和一般手机使用者的安全感都显著负向预测手机依赖；但回避现实社交的中介效应只在手机成瘾者的安全感与手机依赖中显著，在一般手机使用者中不显著。本研究揭示了回避现实社交在手机成瘾者的安全感与手机依赖中的独特作用机制，为失补偿假说提供了实证支持，并为手机成瘾行为治疗开展安全感和社交干预提供了心理学依据。     

网络成瘾大学生对眼部情绪线索识别的研究

在网络飞速发展的现代社会,网络成瘾问题也随之引起社会的高度注意,当今大学生日渐成为网络成瘾的高发人群,一些特定的问题如社交焦虑、幸福感缺失、人际关系紧张等接踵而至。本文旨在通过对眼部情绪图片的识别来对网络成瘾大学生的社交特点进行研究。运用问卷法确定了60名被试组成实验组和对照组,再分别对其进行用DMDX软件编程的眼部情绪线索识别的心理实验。在尽力控制无关变量的影响下,经过数据分析,得出以下结论:网络成瘾大学生与非成瘾大学生对眼部情绪图片识别的正确率和平均正确反应时不存在显著性差异;网络成瘾大学生与非成瘾大学生对正性、中性和负性眼部情绪图片识别的反应时和正确率不存在显著性差异。
