Vigilant self‐regulation,cues of being watched and cooperativeness

The present research examined the interplay of individual differences in self‐regulatory mechanisms as outlined in regulatory focus theory (promotion‐ and prevention‐focus) and a cue of being watched in the context of cooperative behaviour. Study 1 revealed that the more individuals' habitual self‐regulatory orientation is dominated by a vigilant prevention focus, the more likely they are to act cooperatively (i.e. to donate money to natural conservation organizations) when a subtle cue of being watched renders reputational concerns salient. In contrast, when no such cue is provided individuals' habitual vigilant self‐regulatory orientation is negatively related to cooperative behaviour. Study 2 replicated the results of the initial study and examined interpersonal sensitivity (empathic concern) as a potential mediator of the observed effects.

论战国墨家学派发展的四个阶段

依据墨家学说主旨、队伍组织、从事工作,特别是社会作用的不同,可将战国时期墨家学派的发展分为兴盛(公元前444年至公元前381年)、衰败(公元前381年至公元前311年)、转型(公元前311年至公元前250年)、重兴(公元前250年至公元前221年)四个阶段.兴盛阶段,墨家着力游说诸侯、传播学说、制止攻战、助弱国守城;衰败阶段,墨家学派分化内斗,三派弟子活动转型;转型阶段,“谈辩派”后学热衷于空言思辨,“说书派”后学被视为与儒家同类,“从事派”后学对“任侠之风”产生重大影响;重兴阶段,墨家学派声势复盛,“说书派”后学的宣传,“从事派”后学对墨家精神的继承,“谈辩派”后学与儒家、法家的尖锐争辩,都产生了重大社会影响.     

高渗氯化钠羟乙基淀粉40注射液对肝肿瘤并高血压患者硬膜外复合全身麻醉诱导期的脑保护作用

观察预注高渗氯化钠羟乙基淀粉40注射液对肝肿瘤合并高血压患者硬膜外复合全身麻醉诱导期的脑保护作用。选择50例患有高血压ASA分级Ⅱ级～Ⅲ级肝肿瘤手术患者,随机分为高渗氯化钠羟乙基淀粉40注射液(H)组和复方氯化钠(复方乳酸林格液R)组,每组25例。于输注前(T0)、输注完毕即刻(T1)、气管插管后即刻(T2)、气管插管后5min(T3)、气管插管后15min(T4)、气管插管后30min(T5)抽取静脉血离心后检测血清中S100B、IL-6、TNF-a的浓度。与T0点相比,H组,T5点S100B轻度降低但无统计学差异(P0.05),IL-6、TNF-a无明显变化(P0.05);R组在T5点S100B明显上升(P0.01);IL-6、TNF-a明显上升(P0.05或P0.01)。与R组相比,H组患者在T3-5时点S100B、IL-6和TNF-a均低(P0.05或P0.01)。结论为预注高渗氯化钠羟乙基淀粉40注射液在肝肿瘤合并高血压患者硬膜外复合全身麻醉诱导期具有脑保护作用。     

老年髋部骨折围手术期医疗风险的分析与对策

髋部骨折是老年人的常见病之一,髋部骨折对老年人生命的危害最大。随着人口老龄化,老年髋部骨折发病率呈逐年上升趋势。老年骨质疏松髋部骨折围手术期的医疗风险临床较常见,如何降低老年骨质疏松髋部骨折围手术期的医疗风险,是临床骨科需要解决的问题。分析存在的风险问题,明确各种风险因素,尽可能降低老年髋部围手术期的医疗风险。     

他人积极情绪对自我控制资源的替代恢复及机制

替代恢复指通过想象他人资源恢复可恢复自身的资源。研究探讨了他人积极情绪的替代恢复及人际敏感性的调节作用。本研究以331名大学生为被试,实验1和2通过消词任务消耗自控资源后,用文字材料呈现他人积极、他人中性情绪和自我积极情绪,用定价任务考察自控资源的恢复,实验2通过眼神测验测量人际敏感性。结果发现,自控资源消耗后,他人积极情绪组对商品的平均定价比他人中性情绪组低,且只在眼测得分高的个体中存在,他人积极情绪组与自我积极情绪组没有差别。研究证实了他人积极情绪对自控资源的替代恢复及人际敏感性的调节作用。     

Impulsivity and reward sensitivity within the pen model: A test of discriminant hypotheses

Impulsivity and reward sensitivity are often treated as interchangeable constructs. This conflation may be traced back to Gray’s interpretation of impulsivity as the trait level manifestation of the Behavioral Activation System (BAS), that mediates sensitivity to rewards. In this study (N = 696) we evaluated discriminant hypotheses regarding the relationships between BAS-mediated reward sensitivity, impulsivity and Eysenck’s PEN superfactors. We hypothesized that reward sensitivity would be mainly linked with Extraversion, and that impulsivity would be primarily connected with Psychoticism. Hypotheses were tested using structural equation modelling and equality constraints tests. Results mostly supported our expectations: reward sensitivity was more strongly related to Extraversion than to the other PEN superfactors, while impulsivity was more strongly related to Psychoticism and Neuroticism. Implications for BAS and impulsivity research are discussed.     

Prevention-focused self-regulation and aggressiveness

The present research examined the relationship between individual differences in self-regulatory mechanisms as outlined in regulatory focus theory (promotion- and prevention-focused self-regulation) and aggressiveness. Two studies revealed that the more individuals’ habitual self-regulatory orientation is dominated by a prevention-focus, the more likely they are to score high on measures of cynical hostility, reciprocity norm endorsement, and aggressiveness. An additional study involving the manipulation of perceived violation of a reciprocity norm showed that predominantly prevention-focused participants were particularly sensitive to the experience of a norm violation and reacted in a hostile and aggressive manner following the norm violation experience. Findings indicate that a prevention-focused style of self-regulation is associated with aggressiveness and suggest that endorsement of (negative) reciprocity norms and sensitivity to norm violations are relevant factors that help explain the differences in aggressiveness observed among individuals with a predominantly prevention-focused style of self-regulation.     

Accuracy of judging others’ traits and states: Comparing mean levels across tests

Tests of accuracy in interpersonal perception take many forms. Often, such tests use designs and scoring methods that produce overall accuracy levels that cannot be directly compared across tests. Therefore, progress in understanding accuracy levels has been hampered. The present article employed several techniques for achieving score equivalency. Mean accuracy was converted to a common metric, pi [Rosenthal, R., & Rubin, D. B. (1989). Effect size estimation for one-sample multiple-choice-type data: Design, analysis, and meta-analysis. Psychological Bulletin, 106, 332–337] in a database of 109 published results representing tests that varied in terms of scoring method (proportion accuracy versus correlation), content (e.g., personality versus affect), number of response options, item preselection, cue channel (e.g., face versus voice), stimulus duration, and dynamism. Overall, accuracy was midway between guessing level and a perfect score, with accuracy being higher for tests based on preselected than unselected stimuli. When item preselection was held constant, accuracy was equivalent for judging affect and judging personality. However, comparisons must be made with caution due to methodological variations between studies and gaps in the literature.
