High dose alcohol consumption predicts less reduction in post-traumatic stress symptoms after a campus mass shooting

Background: Recognizing that alcohol might affect subsequent processing of trauma-related information, this study examined whether high dose alcohol consumption (HDAC) following a campus mass shooting affected the relation between shooting exposure and post-traumatic stress symptoms (PTSS).

Methods: Female participants (N?=?691) recorded levels of physical exposure to the shooting event, alcohol use, and PTSS 1 month following the shooting event and 8 months later.

Results: No evidence was found to suggest that pre-shooting HDAC moderated the relationship between trauma exposure and PTSS 1 month following the shooting. HDAC in the month following the shooting predicted less resolution of PTSS 8 months later. Specifically, at higher (but not lower) levels of HDAC, shooting exposure was associated with less reduction in PTSS from 1 to 8 months post-trauma. Several alternate explanations were ruled out.

Conclusions: Less reduction in PTSS seems to occur at high levels of both shooting exposure and HDAC. Theoretical implications and directions for future research are discussed.     

Need for uniqueness as a mediator of the relationship between face consciousness and status consumption in China

Strong economic development in China has led to a surge in status consumption as a means of gaining face. In Eastern culture, people interpret uniqueness as status distinction rather than separateness or deviance. This type of uniqueness can be used to meet others' expectations and gain social approval. Thus its relationship with face consciousness and status consumption is to be expected. This study investigates 2 hypotheses: (a) Face consciousness has a positive effect on status consumption and (b) Consumer need for uniqueness mediates the relationship between face consciousness and status consumption. Two‐hundred and forty‐six working respondents in eastern China completed a survey. Regression analysis of the results supported both hypotheses.     

Human Energy Expenditure and Postural Coordination on the Mechanical Horse

The authors investigated and compared the energy expenditure and postural coordination of two groups of healthy subjects on a mechanical horse at 4 increasing oscillation frequencies. Energy expenditure was assessed from the oxygen consumption, respiratory quotient, and heart rate values, and postural coordination was characterized by relative phase computations between subjects (elbow, head, trunk) and horse. The results showed that the postural coordination of the riders was better adapted (i.e., maintenance of in-phase and antiphase) than that of the nonriders, but the energy expenditure remains the same. Likewise, we observed an energy system shifting only for nonriders (from aerobic to lactic anaerobic mode). Finally, cross-correlations showed a link between energy expenditure and postural coordination in the riders (i.e., effectiveness).     

新媒体研究述评及其心理学研究取向

新媒体的横空出世,对人们的生活带来极大影响。针对新媒体自身的一些问题及其影响,国内外进行了一系列研究。在综观相关研究成果基础上,介绍了新媒体的内涵与外延、特征及新媒体时代的起始时间,并主要介绍了新媒体的研究焦点,包括新媒体对人们生活方式及生活质量的影响,影响人们对新媒体态度及行为背后的心理因素分析。最后,在综合评价已有研究的基础上,提出应进一步加强新媒体的心理学研究取向,同时指出新媒体研究问题的具体深入化、方法的多元化及研究的本土化是未来的研究趋向。     

“别人家的孩子”vs.平庸的自己：社会比较对独特性寻求行为的影响

人们在自我评价中普遍存在着优于平均值效应, 而上行社会比较会打破这一自我评价偏差, 引发后续的补偿性消费行为。通过5个实验, 依次论证上行比较(vs.下行比较)会提升个体对独特产品选项的偏好(实验1); 其心理机制在于上行比较降低了而非下行比较提升了个体的自我独特性感知, 从而促使个体出于补偿的目的而寻求独特性(实验2a、2b和2c); 上述效应适用于经济状况这一特定比较维度, 并且在感知经济流动性的调节作用下得到强化或削弱(实验3)。研究结论对于推动社会比较和独特性寻求行为相关领域的理论进展, 指导长尾市场中企业的营销策略、帮助个体缓解上行比较的威胁均有着积极的启示价值。     

产品销量和推荐数对网络消费决策的影响:价格的调节效应

基于目标感染理论,探究了产品销量和产品推荐数对大学生网络消费决策的影响,并进一步探究了产品价格在大学生网络消费决策中的调节作用。两项研究均表明,产品销量和推荐数均会促进大学生做出消费决策。其中,产品价格调节了两者对网络消费决策的影响,具体表现为在选购低价格产品时,大学生更加看重产品销量,倾向选购高销量产品;而在选购中高价格产品时,大学生更加看重产品推荐数,选购高推荐数的产品。本研究为网络电商平台如何针对不同价位产品制定产品展示方案提供了理论支持和实践指导。     

浅析消费领域中的审美现象

随着经济文化的发展和生活水平的提高,消费领域中出现了很多与审美相关的消费。本文透过这些现象分析消费者进行审美消费的内在动因,并且探讨一些应对思路。     

Beyond Consumptive Solidarity: An Aesthetic Response to Human Trafficking

A disturbing economic reality confronts consumers today: thousands of farm workers are enslaved in U.S. agricultural fields, forced to work without pay amid deplorable conditions and under the constant threat of violence. If structural economic injustices perpetuate modern‐day agricultural slavery, then it is necessary to promote consumer practices that resist these abusive dynamics. But a consumption‐oriented strategy does not necessarily restore either personal agency or communal relations damaged by agricultural trafficking. This essay proposes a framework for aesthetic solidarity that cultivates affective bonds necessary for building communities of resistance characterized by mutuality, equality, and participation.     

Chinese Perceptions of Threats from the United States and Japan

People's threat perceptions play a role in influencing foreign policies towards perceived adversary countries. Earlier research has identified multiple components shaping mass-level threat perceptions including military power, adversary country's perceived intentions, and national identities. On the individual level, education, use of media, and interest in politics have been shown to influence threat perceptions. However, most studies on perceptions of security threats fail to include both contextual and individual-level explanatory factors and to consider that different national threats may be constructed differently. This research bridges formation of threat perceptions on the individual level to wider societal processes and provides an empirical perspective to understanding threat perceptions among the educated section of the Chinese population. To analyze threat perceptions, students from leading Chinese universities (N = 771) took part in a survey in the autumn of 2011 and spring of 2012. Respondents who followed conventional media were more likely to perceive both the United States and Japan as threatening, and the effect of media consumption was particularly strong with regards to perceived threat from Japan. In addition, each threat perception was significantly associated with threat-specific explanatory factors. Potential explanatory factors of threat perceptions were explored with linear regression models.     

试论可持续消费的伦理观

可持续消费作为一种消费观念,是在西方国家工业化经济迅速增长,出现世界性的环境恶化、人口膨胀等一系列危机之后,人们进行探索和反思而产生的。人类通过对古代节俭消费观念的重新审视,对传统工业文明消费观的全面批判,于20世纪90年代初步形成了一种新型消费观———可持续消费观。可持续消费观的确立不仅仅是一场消费方式的变革,在更深层次上是人类思维方式、价值观念和发展观念的根本革命。
