Communism,Universalism and Disinterestedness: Re-examining Contemporary Support among Academics for Merton’s Scientific Norms

This paper re-examines the relevance of three academic norms to contemporary academic life – communism, universalism and disinterestedness – based on the work of Robert Merton. The results of a web-based survey elicited responses to a series of value statements and were analysed using the weighted average method and through cross-tabulation. Results indicate strong support for communism as an academic norm defined in relation to sharing research results and teaching materials as opposed to protecting intellectual copyright and withholding access. There is more limited support for universalism based on the belief that academic knowledge should transcend national, political, or religious boundaries. Disinterestedness, defined in terms of personal detachment from truth claims, is the least popular contemporary academic norm. Here, the impact of a performative culture is linked to the need for a large number of academics to align their research interests with funding opportunities. The paper concludes by considering the claims of an alternate set of contemporary academic norms including capitalism, particularism and interestedness.     

高二理科生物理问题创造性解决的表象特征研究

物理问题创造性解决是一个发散思维和聚合思维交替运行的过程,而表象对问题的创造性解决具有重要作用。本研究通过自编的物理问题对天津市某中学109名高二理科学生进行物理问题创造性解决测验,探讨高中理科学生物理问题创造性解决中的表象特征。验证了表象与物理问题创造性解决中的发散思维具有显著的正相关,与聚合思维无显著相关。对109名高二理科学生K聚类分析发现：物理问题解决过程中,高创造性和中等程度创造性的学生人数较少,而低创造性的学生人数较多;表象丰富性很高和较高的学生较少,表象丰富性较低的学生较多。     

拥挤的动机：公益投资中的公共服务动机与外部激励

现代公共管理日益重视公共服务动机,但如何激励公共服务动机,却悬而未决。针对已有研究的局限,采用公益投资博弈的实验范式,考察了激励类型、性别和PSM水平对动机-绩效关系的影响。发现：1）PSM能显著预测公益投资绩效;2）金钱激励撤销后对所有被试均造成了不良后果（动机挤出）;4）荣誉激励能显著提升男性被试的公益投资绩效,且不造成消极后果;但会给女性带来PSM的挤出。未来研究还应考察PSM是否存在内隐层面,并应当考虑文化适合性。     

风险容忍对飞行员驾驶安全行为的影响：风险知觉和危险态度的作用

采用问卷法调查了257名中国航线飞行教员、机长和副驾驶, 通过结构方程模型和层次回归分析探讨了风险容忍对飞行员驾驶安全行为的影响, 以及在这一影响过程中风险知觉和危险态度所发挥的作用。结果发现：(1)风险容忍对飞行员驾驶安全行为具有显著的负向影响, 高风险容忍飞行员的驾驶安全行为水平显著低于低风险容忍飞行员; (2)风险知觉在风险容忍对飞行员驾驶安全行为的影响过程中发挥了调节作用, 即高水平的风险知觉削弱了风险容忍对飞行员驾驶安全行为的负向影响。(3)危险态度在风险容忍对飞行员驾驶安全行为的影响过程中发挥了完全中介作用, 且这种中介作用的实现又受到风险知觉的调节, 即危险态度对飞行员驾驶安全行为的影响是有调节的中介效应。     

英文词、汉字词、早期文字和图画的认知加工比较

采用四种任务考察英文词、汉字词、甲骨文、东巴文和图画在知觉加工和语言加工中的特点, 揭示不同类型符号的认知机制。实验1采用知觉相似度判断和语义一致性判断考察符号在知觉加工和语义加工中的特点; 实验2考察符号在命名与分类中的表现。结果表明：(1)不同类型符号在知觉相似度判断和语义一致性判断中表现不同。符号相似的顺序与文字演化的顺序一致。(2)不同类型符号的命名与分类反应具有不对称性：英文词和汉字词的命名快于分类, 甲骨文、东巴文和图画的分类快于命名。(3)无论是命名还是分类, 对汉字词和图画的反应均快于对东巴文和甲骨文的反应。对英文词命名快于对甲骨文和东巴文命名, 对英文词分类慢于对东巴文分类。(4)英文词、汉字词和图画的命名与分类反应具有不对称性：对英文词、汉字词命名快于对图画命名, 对图画分类快于对英文词、汉字词分类。甲骨文和东巴文的命名与分类反应具有不对称性：对甲骨文命名快于对东巴文命名, 对东巴文分类快于对甲骨文分类。所以如此, 既与符号的外形特征和区别性特征有关, 又与符号记录语言的方式以及对符号的熟悉度有关。研究结果为确定文字发展和演变的规律及甲骨文与东巴文的性质提供了心理学依据。     

认知评价对主观情绪感受和生理活动的作用

围绕认知评价对情绪的作用, 针对传统认知评价实验方法的缺陷, 本研究改进认知评价的操作方法, 以情绪片段为实验材料, 以事先的评价背景替代与观看同步的评价策略, 以生理指标与情绪自评反映情绪变化, 考察41名大学生的认知评价对负性情绪的影响。结果发现, 持有利于情绪调节评价的个体, 负性情绪感受降低, 皮肤电反应减弱, 但心率无变化。研究表明, 认知评价影响个体的主观情绪体验, 并在一定程度上抑制负性情绪所致的生理唤起的增高。     

拥挤效应的特征加工机制

拥挤效应指对外周视野内目标刺激的识别受到该刺激周围无关刺激干扰的现象。大部分研究者认为拥挤效应发生在特征加工水平, 是由刺激特征间的过度整合引起的, 并基于此提出多种理论假设, 包括特征整合、重心解释、强制平均以及相应的量化模型, 但这些模型还缺乏直接的支持性证据。未来的研究应该结合ERP技术, 采用多种刺激(如运动刺激等等), 考察时间和空间维度上的拥挤效应的产生机制。     

Jump Liars and Jourdain’s Card via the Relativized T-scheme

A relativized version of Tarski’s T-scheme is introduced as a new principle of the truth predicate. Under the relativized T-scheme, the paradoxical objects, such as the Liar sentence and Jourdain’s card sequence, are found to have certain relative contradictoriness. That is, they are contradictory only in some frames in the sense that any valuation admissible for them in these frames will lead to a contradiction. It is proved that for any positive integer n, the n-jump liar sentence is contradictory in and only in those frames containing at least an n-jump odd cycle. In particular, the Liar sentence is contradictory in and only in those frames containing at least an odd cycle. The Liar sentence is also proved to be less contradictory than Jourdain’s card sequence: the latter must be contradictory in those frames where the former is so, but not vice versa. Generally, the relative contradictoriness is the common characteristic of the paradoxical objects, but different paradoxical objects may have different relative contradictoriness.

Complexity as a guide to understanding decision bias: A contribution to the favorite‐longshot bias debate

This paper investigates the origins of a widespread decision bias in betting markets, the favorite‐longshot bias (FLB); in particular, whether it is caused by cognitive errors on the part of bettors or by the pricing policies of bookmakers. The methodology is based on previous literature, which has suggested that: (i) races, as decision tasks for bettors, can be distinguished by their degree of complexity and their attractiveness to those with access to privileged information (insiders), (ii) cognitive errors increase as complexity increases, and (iii) bookmakers set odds in a manner to protect themselves from insiders. The degree of FLB was examined in races of varying complexity and attractiveness to insiders using a dataset of 8545 races drawn from the parallel bookmaker and pari‐mutuel markets operating in the UK in 2004. The results, interpreted in the light of the cognitive error and complexity literature, suggest that neither bettors' nor bookmakers' cognitive errors are the main cause of the bias. Rather, bettors' preferences for risk and the deliberate pricing policies of bookmakers play key roles in influencing the bias in markets where bookmakers and pari‐mutuel operators coexist.

The effect of a collision warning system on the driving performance of young drivers at intersections

This study investigated the manner in which the driving performance of young people was affected by a collision warning system when they encountered a driver running a red light at an intersection. Furthermore, the causal relationship among driving performance, traffic factors and intersection accidents was examined using Path Analysis. Participants drove a driving simulator with an intersection collision warning system (ICWS) in a simulated urban area. The driving performance measures recorded were reaction time, speed, lateral position deviation and crash events. Experimental results indicated that drivers who drove a vehicle with an ICWS audio signal at an intersection had a shorter reaction time, a lower speed and a reduced accident rate than those observed while driving a vehicle without ICWS audio signal. Furthermore, Path Analysis showed that the ICWS had an indirect effect on accident rate reduction through improved driving performance. The location of intersection accident had both direct and indirect effects on the accident rate. The number of driving days per week had a direct effect on accident rate reduction.
