从"耳目"、"喉舌"到"向导"、"政监"——略论清末报人的办报理念与公众舆论的话语伦理

清朝末年,随着报刊业的发展和社会思潮的流转,报人对报刊的社会角色和功用提出了自己的理解,始曰“耳目”、“喉舌”,继之言“第四种族”与“舆论之母”,再则称“政监”与“向导”,愈转愈进,愈转愈激。由于立意于作为“政监”和“向导”,报刊特重“主观”之“言论”,遂由“代言”而逐渐转向“灌输”,甚至直接“制造舆论”。因此,尽管报人与报刊仍以代表“公意”、“公益”而自期,但主观之“言论”究竟在多大程度表达了“一般国民之公共意志”而于“民主政治”建设有所贡献,不免令人生疑。     

Effects of Visual Representation on Social Influence in Computer‐Mediated Communication

Two experiments investigated if and how visual representation of interactants affects depersonalization and conformity to group norms in anonymous computer‐mediated communication (CMC). In Experiment 1, a 2 (intergroup versus interpersonal) × 2 (same character versus different character) between‐subjects design experiment (N= 60), each participant made a decision about social dilemmas after seeing two other (ostensible) participants’ unanimous opinions and then exchanged supporting arguments. Consistent with the Social Identity model of Deindividuation Effects (SIDE), when the group level of self‐identity was rendered salient in an intergroup encounter, uniform virtual appearance of CMC partners triggered depersonalization and subsequent conformity behavior. By contrast, when the personal dimension of the self was salient, standardized representation tended to reduce conformity. To elucidate the mediation process, Experiment 2 investigated the causal links between depersonalization, group identification, and conformity. The results show that depersonalization accentuated adherence to group norms, both directly and indirectly via group identification.     

The Multiple Source Effect and Synthesized Speech

Two experiments examine the effect of multiple synthetic voices in an e‐commerce context. In Study 1, participants (N= 40) heard five positive reviews about a book from five different synthetic voices or from a single synthetic voice. Consistent with the multiple source effect, results showed that participants hearing multiple synthetic voices evaluated the reviewed books more positively, predicted more favorable public reaction to the books, and felt greater social presence of virtual speakers. The effects were mediated by participants’ feelings of social presence. The second experiment (N= 40) showed that the observed effects persisted even when participants were shown the purely artificial nature of synthesized speech. These results support the idea that characteristics of synthetic voices in doubly disembodied language settings influence participants’ imagination of virtual speakers, and that technological literacy does not hinder social responses to anthropomorphic technologies such as text‐to‐speech (TTS).     

城市绿化景观观赏性的心理学研究

抽取上海地区具有代表性的公共绿地绿化景观样本,编制测评量表对其观赏性进行评价.通过探索性因素分析鉴别该量表的测评维度并基于理论推断和经验归纳确定评价指标,包括整体美感、正性情绪、色彩知觉、形态知觉、负性感受.120名大学生和研究生对景观样本的评价结果表明.高观赏性组的景观与低观赏性组的景观相比,前者的整体美感、正性情绪、形态知觉、色彩知觉维度评价指标及其所含测项的评分均高于后者,彼此差异达到极显著或非常显著的水平,而负性感受维度评价指标评分则是后者极显著地高于前者,而且其测项评分也显著高于前者.本研究编制的量表能够对城市绿化景观观赏性进行有效测评.     

“儒者”卫礼贤的文化使命:重估儒学

在20世纪初西方文化危机期间,卫礼贤极大地推动了西方对于孔子和儒学的积极评价:他大量译介中国经典,在德国起到了拓荒的作用;他的灵活阐释,拓展了儒学的接受群体;他的"中国"立场,让西方封闭的话语场内多了"他者"的声音。卫礼贤复活作为道德宗师的孔子形象,彰显儒家对道德责任的坚守,令人信服地从西方视角确证了传统儒学的现代价值。他的"跨界"阐释让他得以克服专业局限,为上世纪初的中西文化对话做出了贡献。     

Does spreading activation summate?

Summary Network models of semantic memory assume implicitly or explicitly that the degree of activation of a node is a monotonic function of the total amount of excitation reaching that node from all sources. For example, the activation level of the node representing apple should be greater if it is receiving excitation due to the activation of the nodes for fruit and pear than if only one of these neighboring nodes is activated. This notion was tested by presenting semantic primes 80 ms or 320 ms before a letter string (e.g., apple or ipple) requiring a lexical decision. The prime stimuli consisted of a pair of simultaneous items that were identical in the single prime condition (e.g., fruit/fruit or pear/pear) or different in the double prime condition (e.g., fruit/pear or pear/fruit), and were either related (target = apple) or unrelated (target = copper) to the target, or neutral. As predicted by the summation of semantic activation assumption of network models there was a larger priming effect (in the 320 ms SOA condition) following the simultaneous activation of two related nodes than following the activation of only one node.This research was supported by grants to the first author from the Natural Sciences and Engineering Research Council of Canada.
