进化心理学择偶心理机制假设的跨文化检验

通过对404例天津和432例Boston征婚启事的内容分析,结果发现：（1）男性更关注未来异性配偶的相貌、身材信息,而女性更关注对方的资源与承诺信息,但天津男女征婚者在这两方面都表现得更为强烈;（2）男性随年龄增长,会倾向于更大程度地寻找比自己小的女性,而中美女性则较稳定;（3）Boston人的配偶选择年龄空间较天津人广;（4）在个性特质方面,天津人更关注承诺性,Boston人更关注精神性与“享乐性”。结果表明,进化心理学对男女间差异有较大解释力,但对中美之间的文化差异却缺乏足够说服力。     

分配公正、程序公正、互动公正影响效果的差异

以大学生奖学金评比为例,探讨了组织公正各维度影响效果的差异。以661名大学生为被试,采用2×2×2的完全随机设计,以情境故事法（scenarios）呈现刺激,研究了奖学金评比中分配公正、程序公正、互动公正对大学生学习投入、班级荣誉感、班级归属感、与辅导员的关系的影响。结果表明,组织公正三个维度与效果变量之间存在清晰的对应影响关系：分配公正主要影响具体、以个人为参照的效果变量;程序公正主要影响与组织有关的效果变量;互动公正主要影响与上司有关的效果变量。     

艾滋病恐惧症的研究初探

“艾滋病恐惧症”是一种混合性神经症,核心症状可表现为焦虑、疑病、恐惧、强迫、抑郁症状中的一种或几种的组合,可伴有与艾滋病的临床症状相似的躯体症状,患者感到痛苦,反复求医。该文综合了国外文献和部分案例,对“艾滋病恐惧症”的定义、临床症状、心理病理机制、诊断与治疗等进行了初步的总结与探讨。     

犹太科学运动的政治和民族动因

19世纪上半叶,在犹太学领域兴起的科学运动是在欧洲民族主义普遍发展、现代反犹主义加剧的情况下进行的,它的背后潜藏着深厚政治和民族动因。德意志民族主义一方面强化了反犹主义,使得犹太知识精英在文化界特别是大学面临困境,犹太人从痛苦的经历中感受了一种前所未有的民族存在意识。作为一种正面力量,德意志民族浪漫主义思潮也激发并强化了犹太民族自信心,它与启蒙时代的理性主义汇合,为科学犹太学提供了动力。因此,犹太科学运动可以被看作是犹太民族史上的一场文化复兴运动。     

Influence of the large–small split effect on strategy choice in complex subtraction

Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size.     

The rosy side and the blue side of emotional brand attachment

This paper examines the rosy side (positive emotion) and the blue side (negative emotion) of brand attachment in consumer–brand relationships and their distinct motivational triggers. Adopting attachment theory, self‐determination theory, and the relationship investment model, this paper provides a richer understanding of the positivity and negativity of emotional brand attachment in terms of consequential branding outcomes. Two hierarchical constructs—autonomous and controlled motivations—are proposed and examined using partial least squares path modelling. Data were collected through a 3‐stage survey to gain 507 samples of customers' brand attachments to 9 international car brands. This research reveals that customers' positive‐side (rosy‐side) emotional brand attachments are driven by autonomous motivations including satisfying the intrinsic motivation of pursuing pleasure and fulfilling needs for self‐determination and self‐congruence in the car brand consumption context. Customers' negative‐side (blue‐side) emotional brand attachment reflects feelings of separation distress, anxiety, and sadness that are triggered by their controlled motivations in car brand consumption contexts. The results indicate that positive emotions (the rosy side) of brand attachment are a more effective predictor of brand repurchasing intentions and word‐of‐mouth behaviours than are negative emotions (the blue side) of brand attachment. This study applies Deci and Ryan's autonomous and controlled motivations to explain the positivity and negativity of consumers' emotional brand attachment in brand–consumer relationships.     

Stimulated release of tissue plasminogen activator from artery wall sympathetic nerves: implications for stress-associated wall damage

Recurrent stress is clinically associated with early onset hypertension and coronary artery disease. A mechanism linking emotion to pathogenic remodeling of the artery wall has not been identified. Stress stimulates acute regulated release of tissue plasminogen activator (t-PA) into the circulation, which is presently attributed to the vascular endothelium. Sympathetic neurons also synthesize t-PA and axonally transport it to the arterial smooth muscle. Unlike release by the endothelium, a stress-stimulated sympathetic discharge would potentially accelerate degradation of the wall matrix by plasmin. To assess whether sympathetic axons are the principal source of acute stress-induced arterial release of t-PA, we compared the output from small densely innervated and large sparsely innervated isolated artery segments before and after sympathetic stimulation, and after ablations. Following phenylephrine infusion densely-innervated microvessels in uveal eyecups were released over 60-fold greater amounts of active t-PA per milligram than the sparsely innervated aorta; and ten-fold more than carotid artery segments. Mesenteric artery release was 4.8-fold greater than release by the carotid artery. In vivo, uveal release of t-PA increased more than three-fold within one minute following superior cervical sympathetic ganglion electrical stimulation, and after phenylephrine, or nicotine infusions of the anterior chamber. Circulating levels of t-PA fell 70% following chemical sympathectomy. We propose that sympathetic nerves are the primary source of stress-induced release of t-PA into and from the densely innervated resistance arteries and arterioles, where dysregulated plasmin-induced proteolysis could damage the wall matrix.     

The mediating role of self-efficacy in the development of entrepreneurial intentions

The purpose of this study was to investigate the mediating role of self-efficacy in the development of students' intentions to become entrepreneurs. The authors used structural equation modeling with a sample of 265 master of business administration students across 5 universities to test their hypotheses. The results showed that the effects of perceived learning from entrepreneurship-related courses, previous entrepreneurial experience, and risk propensity on entrepreneurial intentions were fully mediated by entrepreneurial self-efficacy. Contrary to expectations, gender was not mediated by self-efficacy but had a direct effect such that women reported lower entrepreneurial career intentions. The authors discuss practical implications and directions for future research.     

表演式学习──表演理论对“最近发展区”的发展

美国当代心理学家、剧作家、表演理论的创始人弗雷德·纽曼（FredNewman）及其同事致力于在实践中发展维果茨基的理论,从表演的维度探讨了zpd的概念,并以此为核心提出了表演式学习的概念,以区别于在当今社会大行其道的工具性学习,即以获取知识和技能为目的的学习。表演理论通过对工具性学习的消极影响的批判及对表演式学习的倡导,在人的教育和发展方面提出了独到见解。     

基于用户动态信息加工的信息流广告回避机制与重定向策略

信息流广告飞速发展的同时用户广告回避愈发普遍,然而传统广告回避结论无法平移到该情境。本研究基于用户动态的信息加工视角,试图探讨(1)动态信息加工状态下(收敛式vs发散式)产生广告屏蔽和广告跳过行为的内在机制;(2)采用归因引导重定向策略,挖掘用户屏蔽广告的“残留效应”所带来的信号价值;(3)采用广告凸显重定向策略,突破用户跳过广告的“学习效应”造成的负面影响。丰富现有理论的同时,为信息流广告的响应式优化提供理论和决策支持。
