Age-related differences in attentional networks of alerting and executive control in young, middle-aged, and older Chinese adults

Previous studies suggest that aging is associated with impairment of attention. However, it is not known whether this represents a global attentional deficit or relates to a specific attentional network. We used the attention network test to examine three groups of younger, middle-aged, and older participants with respect to the efficiency of three anatomically defined attentional networks: alerting network, orienting network, and executive control network. Age-related change was found to have the greatest effect on the executive network and the least effect on the alerting network as well as on overall mean response time. Impairment of the orienting network was found to be insignificant. Age-related deterioration of the prefrontal lobe, the dopaminergic system, and function of specific genes may explain the age-related changes in executive attention, which occur after the fourth decade of life.     

Expecting the Worst: Moderating Effects of Social Cynicism on the Relationships Between Relationship Conflict and Negative Affective Reactions

Purpose  

Social cynicism, defined as negative beliefs about people and social institutions, shows negative impact on people’s affective reactions. We extended this line of work by testing the moderating effects of social cynicism on the relationships between relationship conflict and its affective consequences.

Testing the efficacy of a new procedure for reducing faking on personality tests within selection contexts

The authors propose a new procedure for reducing faking on personality tests within selection contexts. This computer-based procedure attempts to identify and warn potential fakers early on during the testing process and then give them a chance for recourse. Two field studies were conducted to test the efficacy of the proposed procedure. Study 1 participants were 157 applicants competing for 10 staff positions at a large university located in a southern city in the People's Republic of China. In Study 1, potential fakers received a warning message, whereas nonfakers received a nonwarning (control) message. Study 2 participants were 386 Chinese college students applying for membership of a popular student organization at the same university where Study 1 was conducted. In Study 2, the warning and control messages were randomly assigned to all applicants. Results showed some promise for the proposed procedure, but several practical issues need to be considered.     

The cost of serially chaining two cognitive operations

As Turing (1936, Proceedings of the London Mathematical Society) noted, a fundamental process in human cognition is to effect chained sequential operations in which the second operation requires an input from the preceding one. Although a great deal is known about the costs associated with 'independent' (unrelated) operations, e.g., from the classic psychological refractory period paradigm, far less is known about those operations to which Turing referred. We present the results of two behavioural experiments, where participants were required to perform two speeded sequential tasks that were either chained or independent. Both experiments reveal the reaction time cost of chaining, over and above classical dual-task serial costs. Moreover, the chaining operation significantly altered the distribution of reaction times relative to the Independent condition in terms of an increased mean and variance. These results are discussed in terms of the cognitive architecture underlying the serial chaining of cognitive operations.     

面向实践的技术知识——人类学视野的技术观

<正>近30年来,人类学对技术的研究已经将人们的技术观从人工物中心观和建构主义中心观推进到社会技术系统观。通过活动棱镜或者身体中介的引入,人和物被铸造成一个更加紧密的无缝之网,它是身体的、生理的、心理的、社会的、文化的以及物质的有机整体。这种新形成的技术观是一种更具经验性的、更少决定论的、更多建构论的和语境依赖性的技术意象。     

大学生网络幸福感的特点及其与网络使用偏好的关系

采用自编的大学生网络幸福感问卷、网络使用偏好问卷,对400名大学生进行测试,以探索大学生网络幸福感的特点及其与网络使用偏好的关系。结果表明：（1）大学生的网络幸福感总体处于中等偏上水平,网络使用偏好中休闲娱乐维度的得分最高,网络使用偏好类型中普通型居主导地位;（2）网络幸福感和网络使用偏好类型存在显著正相关,其中与休闲娱乐偏好的相关最高;（3）回归分析结果表明,休闲娱乐偏好对网络幸福感有正向预测作用,游戏偏好对网络幸福感中的便利感、活力感、自由感因子有预测作用。     

《碧霞元君护世弘济妙经》考辨

泰山灵应宫内明万历铜钟铭文《太上老君说天仙玉女碧霞元君护世弘济妙经》属藏外遗经。它的发现,对于研究碧霞元君信仰和搜辑道教遗经续修道藏具有重要的意义。本文就铸经的因缘、经文内容、著作时间等予以初步考证辨析,并校录经文。     

试论和玉蟾与李灵阳对全真道创立的贡献

全真道为王重阳所创立,这是历史的结论。但王重阳早期修道于终南山,并非孤身一人。王重阳于金大定七年(1167年)自焚茅庵,前往山东接收七真高徒,大定九年在返回关中途中仙逝于开封。马丹阳等四人赴终南,迅速站稳脚跟,营建起全真道的大本营,也不是完全在废墟上另起炉灶。从中起到
