The Effect of Message Persistence and Disclosure on Liking in Computer-Mediated Communication

In computer-mediated communication (CMC) systems, the messages that a user types usually persist on the screen for some time, a feature that distinguishes CMC from face-to-face interaction. Persistence may activate psychological self-perception, leading communicators to infer from their persistent messaging how they feel about the subject more so than if messages did not persist. This study applies persistence and self-perception to the relationships between self-disclosure and liking. It identifies which among several disclosure or liking relationships may be most susceptible to self-perception effects. An experiment found that message persistence interacts with a conversational partner’s responses to self-disclosure and intensifies liking toward the partner. Suggestions follow for future research further exploring the mechanisms of persistence, and reconceptualizing self-perception factors in interactive media settings.     

Dorsomedial prefrontal cortex 5-HT6 receptors regulate anxiety-like behavior

The dorsomedial prefrontal cortex (dmPFC) plays a very important role in decision-related and anxiety-related information processing. It has enriched 5-HT6 receptors; however, the precise role of dmPFC 5-HT6 receptors in anxiety remains to be fully investigated. In this study, we injected dmPFC with the 5-HT6 receptor agonist EMD 386088 and antagonist SB 271046 using stereotactic technology. 5-HT6 receptor activation in mice increased time spent in the center area on the open-field test, increased exploration of the open arms on the elevated plus maze test, and increased ratio on the social interaction test. 5-HT6 receptor inactivation induced the opposite effects. In brain slices, EMD 386088 decreased both spontaneous inhibitory postsynaptic currents (sIPSC) and spontaneous excitatory postsynaptic currents (sEPSC), while SB 271046 only increased sEPSC. These effects of EMD 386088 and SB 271046 could be reversed by the GABA_A receptor antagonist bicuculline (BMI) and positive allosteric modulator clonazepam (CLZ), respectively. Our results suggest that neurotransmission in the dmPFC by 5-HT6 receptor activation and inhibition may play an important role in anxiety-like behavior, and may provide new insight into the pathological mechanism and potential target of anxiety disorders.     

抑郁对社会决策的影响

从社会决策角度出发,依托博弈论的经典范式是研究抑郁症病人人际与社会功能障碍的一个切入点。Ruff和Fehr （2014）提出在社会决策中存在三类情境,即社会反馈、替代性评价、社会原则。我们从这个理论框架出发,发现抑郁症病人在社会反馈加工中存在社会性快感缺失,对社会拒绝的敏感性增强;在替代性评价过程中,共情和心理理论能力减弱;抑郁症病人对决策中的社会原则（公平、合作）存在适应不良现象,如过度利他性。未来的研究一方面可进一步探索抑郁症病人的社会性快感缺失现象,另一方面可采用经颅电/磁刺激与脑成像技术结合或超扫描技术,提高研究结果的解释力和生态效度。     

基于团体平衡视角的公立医院改革模式分析

通过分析公立医院改革中的相关利益集团及团体冲突,发现改革的动力主要来自城乡居民和中央政府,阻力主要来自公立医院和地方政府.对公立医院改革的四种模式进行了相关利益集团的利益损益剖析并从团体平衡的视角探究改革政策形成过程的不足、政策内容设计的缺陷.提出政府平衡各团体利益的五种途径:明确改革的价值取向和目标、厘清政府与公立医院的关系、制定游戏规则、协调利益冲突、干预利益格局.     

中国古代麻醉术发明史

古代麻醉术的发明起源于中国,在现代麻醉传入前,中国在麻醉术的应用方面已有一定的经验积累和实际应用.东汉时期,华佗最早将麻醉技术用于外科,晋唐时期医家将全身麻醉法更多地用于临床,创造性地将针刺术用于麻醉,宋金元以后的认识和运用更趋细密.历经几千年,麻醉术经过从经验到科学,从粗糙趋精细的漫长艰难探索过程.

小学傣汉双语者汉语词汇形音的语义通达特点

采用语义启动研究范式,探讨傣族小学2、4、6年级汉语词汇和语音的语义通达特点。结果表明：1）对图片语义的提取存在学习年龄效应,2年级的反应时显著长于4、6年级;2）汉语词汇和语音都能显著促进图片语义的提取,但语音促进作用更明显;3）汉语词汇对图片语义提取的促进作用随年级的升高而增加,汉语语音的促进作用随年级的升高而减少。     

高职生时间管理倾向与成就动机的关系研究

文章采用《青少年时间管理倾向量表》和《成就动机量表》对贵州省3个高职院校577名学生进行了问卷调查,结果发现,高职男生在时间效能感、时间价值感和时间监控观上显著高于女生;高职生的时间管理倾向与成就动机存在显著相关,其中高职生的时间管理倾向各维度与追求成功的动机存在显著的正相关,与避免失败的动机存在显著的负相关;高职生的高时间管理组在追求成功的动机上显著高于低时间管理组,而在避免失败的动机上低于低时间管理组;时间价值感、时间监控观对追求成功的动机具有显著的预测力,时间价值感、时间监控观和时间效能感对避免失败的动机具有显著的影响力。
