Price as a quality or sacrifice cue: Role of goal orientation

Prior research seems to have neglected the factors that influence consumers to use price information as an indicator of quality or sacrifice. Based on the concept of 'goal looms larger', Study 1 in the present research demonstrated that the extent to which consumers use price information as an indicator of quality or sacrifice is a function of consumer goal (promotion focus vs prevention focus). Study 2 demonstrated that extremeness aversion is a function of consumer goal. The extent of extremeness aversion is significantly greater for prevention-focused consumers than for promotion-focused consumers.     

病理性互联网使用与情绪、认知需要的模型构建

通过对1030名大学生进行问卷调查.对大学生的情绪、认知需要与网络成瘾的关系进行了探讨.结果发现:消极情绪对网络成瘾有显著而直接的正向作用.消极情绪对网络成瘾具有最强的预测力;认知需要对网络成瘾有显著而直接的负向作用;消极情绪和积极情绪均可通过认知需要间接地影响网络成瘾;男女生的情绪、认知需要对网络成瘾的影响存在差异.     

教学计划过程中教学专长的专家一新手比较研究

教学专长的研究多出现在教学实施阶段,且很少描绘教师知识及其组织.本研究运用出声思维法对4组专家与新手教师进行了教学计划过程中知识提取量与质的比较研究,研究发现,与新教师相比,专家教师的教学计划过程更周密、审慎,表现出更精致、联系性更强的教学专长.     

诚信人格特质初探

本研究旨在探讨诚信人格特质的结构.利用人格词评定法,通过探索性因素分析得出诚信人格结构包括正性取向:实干重义、诚实信用、公正无欺、忠实可靠;负性取向:自私欺人、钻营世故、多谋寡信、虚伪不实.并通过验证性因素分析检验,结果表明所得的八个因素与诚信人格的结构拟合较好.     

青少年的同伴依恋与其互联网使用的关系

青少年期同伴群体的支持逐渐超过了父母的影响.青少年期同伴依恋在青少年认知、情感、人格以及行为的健康发展和社会适应中起着重要作用,拥有亲密的同伴关系的青少年出现情感问题和行为问题的可能性更小,并拥有更健康的青少年期适应能力.该研究采用同伴依恋量表、互联网服务使用状况量表以及青少年病理性互联网使用量表对405名中学生进行了问卷调查.旨在探讨青少年同伴依恋与其互联网使用之间的关系.结果表明: (1)同伴信任与社交和娱乐服务的使用偏好呈负相关,尽管都没有达到统计显著性; (2)同伴沟通可以正向预测青少年对信息、娱乐和社交服务的使用偏好,且都达到显著性水平;还可以通过互联网娱乐服务使用偏好间接预测PIU; (3)青少年与同伴的疏离程度可以正向预测青少年对社交服务的使用偏好,也可以直接正向预测PIU.     

非良基集合的外延公理

近年来,由于非良基集合在人工智能、认知科学及哲学等领域都有很重要的应用,它的研究越来越受到人们的关注。判断两个对象的同一性是集合论中最基本的问题,然而,与良基集合不同的是,非良基集合难以找到其最基本的组成成分,这样通常的外延公理就无法判断两个非良基集合（例如x={x}和y={y}）相等。为了找到判断两个非良基集合相等的标准,我们必须强化通常的外延公理。利用Aczel四种非良基公理（AFA,SAFA,FAFA和BAFA）,我们推出了四种判断两个非良基集合相等的标准,并且举例说明对于给定的两个非良基集合,如何判断它们相等,从而解决“循环集合”相等的问题。此外,笔者进一步论证判断这四种非良基集合相等的标准是通常外延公理的扩张,而不是替代。为此,本文首先给出了集合和图的一些基本定义和结果;其次讨论了由四种非良基公理AFA,SAFA,FAFA和BAFA分别确定的四种集合全域A,S,F和B;最后,讨论了外延公理的扩张。

Age of acquisition affects early orthographic processing during Chinese character recognition

Three experiments investigated age of acquisition (AoA) effects on early orthographic processing during Chinese character recognition. In Experiment 1, we measured the accuracy of identification of brief masked characters, accuracy was higher for early compared to late acquired characters. In Experiment 2, the visual duration threshold (VDT) was measured for both early and late acquired Chinese characters. The results showed that early acquired characters were successfully identified at shorter display durations than late acquired characters. Significant AoA effects were also found in Experiment 3, using a lexical decision task requiring mainly orthographic processing (discriminating real Chinese characters from orthographically illegal and unpronounceable characters). In summary, three experiments provide converging empirical evidence, for AoA effects on the early orthographic processing stages of Chinese character recognition. These results suggest that AoA effects during word identification go beyond the phonological or semantic processing stages. These results aslo provide cross-linguistic evidence for an AoA effect on early perceptual processing during identification.     

Complete Extensions in Argumentation Coincide with 3-Valued Stable Models in Logic Programming

In this paper, we prove the correspondence between complete extensions in abstract argumentation and 3-valued stable models in logic programming. This result is in line with earlier work of [6] that identified the correspondence between the grounded extension in abstract argumentation and the well-founded model in logic programming, as well as between the stable extensions in abstract argumentation and the stable models in logic programming.
