心房颤动的病因、发病机制与射频导管消融治疗现状

随着人们研究的不断深入,对心房颤动的病因、发病机制有了更新的认识。后者从起搏点兴奋性增高,折返机制,发展到对心肌袖、电重构的认识;以及肺静脉、迷走神经在阵发性心房颤动中的作用,遗传物质异质性及基因突变等。同样,心房颤动的射频导管消融治疗也取得了突破性的进展。

Is it harmful to me or to us? A dyadic analysis of Chinese young adults' dysfunctional individuation and romantic relationship satisfaction

This study aimed at examining how romantically involved Chinese young adults' dysfunctional individuation was associated with their and their partners' perceptions of romantic relationship satisfaction. We recruited 296 Chinese couples who were currently in heterosexual romantic relationships at the university. The couples completed self-report measures of their dysfunctional individuation and relationship satisfaction. Results from the cross-sectional actor–partner interdependence model (APIM) indicated that (a) for both genders, actor effects existed: Chinese young adults' dysfunctional individuation was negatively associated with their romantic relationship satisfaction; (b) in terms of partners' effects, women's dysfunctional individuation was negatively associated with men's perceptions of relationship satisfaction; but (c) men's dysfunctional individuation was not significantly associated with women's perceptions of relationship satisfaction. The findings were the first to reveal the actor and partner effects of dysfunctional individuation on romantic relationship satisfaction. The study results provided practical implications regarding how young adults can have satisfying romantic relationships.     

人事选拔中的应聘者反应研究述评

应聘者反应是个体在选拔情境下由公平知觉导致的一种针对组织的态度或行为后果.应聘者反应的首个理论模型是Gilliland的选拔公正模型,随后,启发模型、整合模型和信任模型相继建立,极大丰富了应聘者反应的理论内涵.然而,应聘者反应的测量明显滞后于理论的发展,主要表现在测量工具不统一、测量结构混乱、信效度研究匮乏等方面.未来的研究方向有:(1)加强现有模型中论证不充分的环节;(2)进一步丰富跨文化研究;(3)从一般性问题向特定情境的研究进行深入;(4)结合跨领域内容,朝着多元化的方向发展.     

Mortality of geriatric and younger patients with schizophrenia in the community

Little is known about the differences in mortality among non-institutionalized geriatric and younger patients with schizophrenia. In this study long-term mortality and suicidal behavior of all the geriatric (age > or = 65 years), middle-age (age 41-64 years), and young (age 15-40 years) subjects with schizophrenia living in a Chinese rural community were compared. A 10 year follow-up investigation among a 1994 cohort (n = 510) of patients with schizophrenia was conducted in Xinjin County, Chengdu, China. Compared with young subjects, geriatric subjects with schizophrenia were more likely to be female, have more previous physical illness, never accepted treatment, and practice religious (p < or = 0.01). There were no significant differences of suicide attempts among the three groups. Young subjects had a higher rate of suicide (1,033.8 per 100,000 person-years), and geriatric subjects had a higher rate of deaths due to other causes (accident and natural causes) (4,314.2 per 100,000 person-years). Standardized mortality ratios for both suicide and deaths due to other causes were highest in young subjects and the lowest in geriatric subjects. Patients with schizophrenia in all age groups had a marked increase in mortality and suicide. Specific intervention strategies for decreasing mortality and suicide should be developed for patients with schizophrenia in different age groups.     

正面自我标签对建议采纳的影响

研究设想给决策者“贴标签”会影响其建议采纳, 即当决策者受到某一词语或文字(标签)的描述, 其往往向标签所预示的方向发展。通过三个依次递进的研究, 探讨在有无获益希望及公开与否三种不同组合的决策场景中, 启动决策者正面自我标签对其建议采纳的影响。实验1采用2(正面自我标签：启动/未启动)×2(获益希望：有/无)组间设计, 实验2和实验3分别进一步研究无获益希望的公开场景和有希望获益的不公开场景, 分别以91、135和96名在校大学生为被试。结果发现：决策者正面自我标签启动使得其更容易采纳建议; 无获益希望公开条件下, 受印象管理或社会赞许性影响而显著提高建议采纳; 有获益希望的公开条件下, 决策者正面自我标签启动使得其积极情绪得到提升, 并进而促进其采纳建议, 而积极意义发现在积极情绪和建议采纳之间起中介作用。     

Automatic goal inferences

The social psychological literature on automatic social inferences has focused on one construct that helps explaining human behavior—traits (e.g., Gilbert, Pelham, & Krull, 1988; Trope, 1986; Winter & Uleman, 1984). The dispositional roots of behavior, however, go beyond relatively stable constructs such as traits to include more transient causes such as one’s intentions and goals. Evidence from young infants and adult chimpanzees, knowledge acquired in the text-comprehension literature and hypotheses derived from the Automatic Causal Inferences framework (Hassin, Bargh, & Uleman, 2002), seems to converge: they all suggest that perceivers may automatically infer goals from behaviors. This paper reports four studies that examine this hypothesis. The first two use surprise cued-recall, and look at goal inferences when the road to goal achievement seems straightforward and when it seems blocked. Studies 3 and 4 use on-line methodologies—probe recognition task and lexical decision—to examine whether these inferences are made at encoding.     

负性事件引发情绪反应的性别特点及神经机制

选取45名大学本科生为被试,记录被试观看内容不同的刺激材料时主观情绪体验成绩,同时采集了心率变异性(HRV)的频域指标,探讨内容不同的负性事件引发情绪反应的性别特点及外周神经机制.结果:在主观报告上,女性所诱发的负性情绪显著高于男性.社会事件的情绪材料所引发的负性情绪显著高于家庭事件的情绪材料.在生理指标上,女性在负性事件中引起的LF/HF显著高于男性.因此,负性事件后男性和女性情绪反应在主观应激强度和生理反应模式上差异显著.     

Listening,Watching, and Reading: The Structure and Correlates of Entertainment Preferences

ABSTRACT People spend considerable amounts of time and money listening to music, watching TV and movies, and reading books and magazines, yet almost no attention in psychology has been devoted to understanding individual differences in preferences for such entertainment. The present research was designed to examine the structure and correlates of entertainment genre preferences. Analyses of the genre preferences of more than 3,000 individuals revealed a remarkably clear factor structure. Using multiple samples, methods, and geographic regions, data converged to reveal five entertainment‐preference dimensions: Communal, Aesthetic, Dark, Thrilling, and Cerebral. Preferences for these entertainment dimensions were uniquely related to demographics and personality traits. Results also indicated that personality accounted for significant proportions of variance in entertainment preferences over and above demographics. The results provide a foundation for developing and testing hypotheses about the psychology of entertainment preferences.     

Goal contagion: perceiving is for pursuing

Six studies examined the goal contagion hypothesis, which claims that individuals may automatically adopt and pursue a goal that is implied by another person's behavior. Participants were briefly exposed to behavioral information implying a specific goal and were then given the opportunity to act on the goal in a different way and context. Studies 1-3 established the goal contagion phenomenon by showing that the behavioral consequences of goal contagion possess features of goal directedness: (a) They are affected by goal strength, (b) they have the quality of goal appropriateness, and (c) they are characterized by persistence. Studies 4-6 show that people do not automatically adopt goals when the observed goal pursuit is conducted in an unacceptable manner, because the goal will then be perceived as unattractive. The results are discussed in the context of recent research on automatic goal pursuits.
