Computer-Mediated Communication Versus Vocal Communication and the Attenuation of Pre-Interaction Impressions

Conflicting theoretical approaches yield divergent predictions about the effects of telephones versus computer-mediated communication (CMC) in the persistence or dissipation of pre-interaction expectancies. Moreover, different theoretical orientations and their underlying assumptions often invoke different methodologies, which can bias the results of research. The current studies articulate and assess rival hypotheses from alternative theoretical paradigms to uncover how CMC and vocal communication affect interpersonal impressions. Methodological issues in past CMC research are evaluated that limit the generalizability of previous findings in the area. Experiments employing alternative assumptions and methods indicate that CMC is functionally equivalent to vocal communication in its ability to ameliorate expectancies and that in some cases it can be superior in transmitting positive impressions.     

自尊的遗传性:来自双生子研究的证据

自尊是个体差异的一个重要方面,迄今已有许多研究从行为遗传学角度探讨自尊个体差异的来源。通过梳理现有关于自尊的双生子研究,发现:1)自尊有中等的遗传度,其个体差异来自遗传和非共享环境;2)遗传对自尊的稳定性有较大作用;3)自尊与认知、情感的联系主要源自共同的遗传基础。总之,遗传对自尊具有重要影响。未来双生子研究可拓展到自尊波动性、内隐自尊等领域,并考虑极端人群的遗传特异性和文化对自尊遗传性的影响。     

基于双加工理论解释下信念偏差效应的神经机制

信念偏差效应是指人们已有的知识信念对逻辑推理的影响现象.对此,双加工理论认为这是由于信念偏向系统和逻辑分析系统之间的冲突所导致的.近年来,该理论得到来自认知神经科学证据的有力支持:一方面,基于功能磁共振成像(fMRI)、近红外光谱(NIRS)以及重复性经颅磁刺激(rTMS)等技术的研究从不同角度证实右侧前额皮层与信念偏差抑制有关;另一方面,基于脑电(ERP)的研究表明,晚期正成分和晚期负成分可能参与了不同推理类型下信念偏差效应的认知加工.未来的研究可以从工作记忆、不同加工阶段、推理前提本身可信度、实验分析、实验材料生态学效度以及思维训练等方面对信念偏差效应作进一步探索.     

Meritorious Evaluation Bias: How Chinese Undergraduates Perceive and Evaluate Chinese and Foreign Creators

This study examined how Chinese young people perceived Chinese and foreign creators with a meritorious evaluation bias. Two separate studies were conducted. In Study 1, a pool of the most noted Chinese creators was generated and they were rated on degree of creativity and social contribution. In Study 2, a pool of the most noted foreign creators was generated and they were rated on degree of creativity and social contribution. In addition, 20 most noted historical and modern Chinese creators were singled out from Study 1 and were rated on degree of creativity and social contribution as well. 414 and 212 undergraduates from two universities in Hong Kong and Guangzhou were sampled to participate in these studies respectively. The results showed that the Chinese and foreign creators who distinguished themselves in meritorious salience of a person's creativity were more likely to be nominated and were rated higher on social contribution than on creativity. Scientists, inventors, and to some extent, politicians were the most often nominated figures of creativity. Artists, musicians and entertainers were the least often nominated figures of creativity.     

漫谈《诗经》的翻译

一、诗歌是不是可译的? <诗经>是五经之一,分风、雅、颂三部分,都是诗.郭绍虞先生认为,风相当于抒情诗(普通传诵的民谣ballad);雅相当于史诗:大雅是天子一般宴乐场合演唱的颂歌(ode),小雅是贵族集会演唱的颂歌;颂相当于戏诗(即祭祀时的颂歌).     

An Appraisal Account of Individual Differences in Emotional Experience

People can differ tremendously in the emotions they experience, both in general as well as in response to specific events, and such differences have large impact on their lives. Based on recent research on individual differences in appraisal and emotion, we propose a framework to understand the basis for individual differences in emotional experience. In this framework, individual differences in how people appraise their circumstances and in how these appraisals are related to emotional experience are seen as crucial in determining how people differ in both contextualized emotional experience and more stable emotional dispositions. We discuss parallels with other explanatory frameworks, implications for the nature of emotion traits, and directions for future research.     

视时距知觉适应后效的空间选择性

时距知觉适应后效是指长时间适应于某一特定时距会导致个体对后续时距产生知觉偏差。其中对视时距知觉适应后效空间选择性的探讨存在争议,有研究支持位置不变性,也有研究支持位置特异性。这类研究能有效揭示时距编码的认知神经机制,位置不变性可能意味着时距编码位于较高级的脑区,而位置特异性则可能意味着时距编码位于初级视觉皮层。未来还可以探究时距知觉适应后效的视觉坐标表征方式,开展多通道研究以及相应的神经基础研究。     

Delayed reward learning: Disproof of the traditional theory

Without the aid of secondary rewards to bridge the temporal gap, each of 15 rats learned to select the rewarded side of a T-maze although the reward was delayed until 1 min after the response was emitted. Similar results were obtained from another group of eight rats for which the length of the delay was 5 min. In a final experiment using the same basic procedure, five groups of rats were trained for 25 days with delays of 0.5, 1.0, 2.0, 4.0, or 8.0 min. The percentage of correct responses did not significantly differ among groups. According to prevailing psychological theory, these results are impossible.     

Contour displacements and tracking errors: Probing ’twixt Poggendorff parallels

Explanations of the Poggendorff effect were tested by varying the separation between outer parallels and by adding interior parallels. Error decreased with the addition of interior parallels, which can be explained by repulsion of parallels. A strong linear trend existed for judgmental error in millimeters plotted against separation between outer parallels. The nonzero intercept of a best-fit line and the slight nonlinearity of the data suggest a hypothesis of contour repulsion between parallels at moderate separations coupled with mistracking of the transversal across the region between parallels. Since the Poggendorff effect was independent of viewing distance, perceptual errors cannot be explained by purely peripheral mechanisms. A true intersection between transversal and parallel was the most critical feature of a display. Inverting a display increased the mean error.
