人格特质对微信用户朋友圈点赞行为动机影响的研究

移动互联网时代,微信的出现颠覆了人们的沟通方式,而点赞作为网络人际之间的互动更是呈现了用户的个人调节与社会认同。本研究采用问卷的方法,对368名微信用户的点赞动机与人格特质的关系进行调查。结果发现:(1)点赞行为有着不同的动机背景,这其中主要是自我认同和社会认同动机在起推动作用。(2)这其中不同动机的人又有着不同的人格特质,具体而言,严谨性与外向性影响自我认同,而宜人性与开放性影响社交认同。     

Inter-Definability of Horn Contraction and Horn Revision

There have been a number of publications in recent years on generalising the AGM paradigm to the Horn fragment of propositional logic. Most of them focused on adapting AGM contraction and revision to the Horn setting. It remains an open question whether the adapted Horn contraction and Horn revision are inter-definable as in the AGM case through the Levi and Harper identities. In this paper, we give a positive answer by providing methods for generating contraction and revision from their dual operations. Noticeably, we cannot apply the Levi and Harper identities directly in such methods as the Horn fragment does not fully support negation. To overcome this difficulty, a Horn approximation technique called Horn strengthening is used. We show that Horn contraction generated from Horn revision is always plausible whereas Horn revision generated from Horn contraction is, in general, implausible and, to regain plausibility, the generating contraction has to be properly restricted.     

义符促进类别归纳推理的ERP证据

为了明确义符对归纳推理影响,本研究使用有义符和无义符汉字为材料,使用ERP技术考查义符对不同层级类别概念归纳推理的影响。行为结果显示,有义符条件下反应速度更快,肯定判断率更高。脑电指标上,P3阶段义符主效应显著,有义符条件下P3波幅更大;N1、N400和P600阶段义符与层级交互作用显著,组内简单效应分析显示,层级主效应仅在无义符条件下显著;组间简单效应分析显示,义符主效在N400和P600阶段仅在下-上推理条件下显著,无义符条件下,下-上推理引发更大的N400和P600波幅。这些结果表明,义符促进了归纳推理过程,这种促进主要表现在对下-上推理的促进。     

Information Mismatch: Cancer Risk Counseling with Diverse Underserved Patients

As genetics and genomics become part of mainstream Medicine, these advances have the potential to reduce or exacerbate health disparities. Gaps in effective communication (where all parties share the same meaning) are widely recognized as a major contributor to health disparities. The purpose of this study was to examine GC-patient communication in real time, to assess its effectiveness from the patient perspective, and then to pilot intervention strategies to improve the communication. We observed 64 English-, 35 Spanish- and 25 Chinese-speaking (n = 124) public hospital patients and 10 GCs in 170 GC appointments, and interviewed 49 patients who were offered testing using the audio recordings to stimulate recall and probe specific aspects of the communication. Data analyses were conducted using grounded theory methods and revealed a fundamental mismatch between the information provided by GCs and the information desired and meaningful to patients. Several components of the communication that contributed to this mismatch and often resulted in ineffective communication included: (1) too much information; (2) complex terminology and conceptually difficult presentation of information; (3) information perceived as not relevant by the patient; (4) unintentional inhibition of patient engagement and question-asking; (5) vague discussions of screening and prevention recommendations. Our findings indicate a need to transform the standard model of genetic counseling communication using evidence-based principles and strategies from other fields of Medicine. The high rates of limited health literacy in the US, increasing access of diverse populations to genetic services, and growing complexity of genetic information have created a perfect storm. If not directly addressed, this convergence is likely to exacerbate health disparities in the genomic age.     

气质性乐观的正性偏向及其神经生理研究证据

气质性乐观是对未来的总体的积极期待。乐观能够带给个体诸多好处, 如有利于提高身体健康, 提高幸福感, 促进成功等等, 究其原因可能是乐观者存在正性偏向。这一偏向主要体现在注意、知觉、记忆、解释风格、应对策略的选择、情绪、期待及动机方面。而乐观者正性偏向产生的神经生理机制可能与前扣带回喙部、前额叶皮质的激活水平变化有关。未来研究可将乐观的核心--期待--作为重点, 整合期待−价值理论、人格理论与神经基础来进一步探讨乐观的心理机制。     

阅读中的快速启动范式述评

快速启动范式（Sereno & Rayner, 1992）是一种基于呈现随眼动变化技术而设计的眼动范式,主要用于研究中央凹视野内字词识别的瞬时启动,通过精确控制启动条件和启动时窗,以考察词汇通达过程中词汇水平（如,词频、词长等）、亚词汇水平（如,语音、语义、字形等）信息的加工时序。本文从基本原理、设计基础、应用领域、注意事项等方面对快速启动范式进行了较为深入的解读和介绍,并结合已有的研究成果,指出了该范式在汉语阅读中的应用价值。     

价值-项目间隔和项目呈现时间对价值导向元记忆的影响*

采用选择性任务范式,用2个实验考察价值-项目间隔和项目呈现时长对价值导向元记忆的影响。实验1考察不同价值-项目间隔（无, 1s, 2s）时被试的选择性记忆指标SI和记忆成绩。结果发现,随价值-项目间隔增加,被试的记忆选择性逐渐下降,间隔1s时对高价值项目的选择性仍存在,但间隔2s时消失;实验2选取实验1的两种价值-项目间隔（无, 1s）条件,延长其项目呈现时间至4.5s,考察项目呈现时间对价值导向元记忆的影响。结果发现,两种价值-项目间隔条件下记忆选择性水平（SI）均显著降低,但对高价值项目的选择性加工优势并没消失。结论：价值导向元记忆受价值-项目间隔和项目呈现时间的影响。
