Effects of playing violent videogames on Chinese adolescents' pro-violence attitudes, attitudes toward others, and aggressive behavior.

This study examines the effects of exposure to online videogame violence on Chinese adolescents' attitudes toward violence, empathy, and aggressive behavior. Results of bivariate analyses show that playing violent videogames on the Internet was associated with greater tolerance of violence, a lower emphatic attitude, and more aggressive behavior. Results of hierarchical regression analyses showed sustained relationships between exposure and pro-violent attitudes and empathy when exposure was examined simultaneously with gender, computer use, and Internet use. However, the linkage between exposure and aggression became non-significant, suggesting that the effects of playing violent videogames were greater for attitudinal outcomes than on overt behavior. Gender differences in playing videogames and in effects were also found.     

Implicit working memory

Working Memory (WM) plays a crucial role in many high-level cognitive processes (e.g., reasoning, decision making, goal pursuit and cognitive control). The prevalent view holds that active components of WM are predominantly intentional and conscious. This conception is oftentimes expressed explicitly, but it is best reflected in the nature of major WM tasks: All of them are blatantly explicit. We developed two new WM paradigms that allow for an examination of the role of conscious awareness in WM. Results from five studies show that WM can operate unintentionally and outside of conscious awareness, thus suggesting that the current view should be expanded to include implicit WM.     

名词短语加工中个体量词通达的影响因素

“双系统”和“双向选择组合网络”理论认为,在汉语使用者的心理词典中存在名词系统和量词系统,两者之间存在双向选择关系。采用启动范式考察在名词短语产生和理解中量词的名词搭配量、名词的量词拥有量和量词-名词定配率对个体量词通达的影响。结果表明,量词的名词搭配量、名词的量词拥有量和量词-名词定配率显著地影响量词的词汇通达,量词和名词之间是双向选择关系。量词通达是直接通达和间接通达的有机结合。     

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。     

情境相关性及其对“特质-工作结果”的调节作用

情境相关性是指当情境能够对个体表达特质提供相关行为的线索时, 该情境即具有相关性, 它和情境强度共同组成特质激活的潜能, 并在工业组织心理学中逐渐受到广泛关注。基于情境相关性有研究提出情境维度说, 建立特质激活与评估模型。受到情境中相关线索激活, 特质表达为工作行为。在与不同水平各个维度的线索相一致时, 工作行为被评估为工作绩效。研究表明, 情境调节变量可以在3个水平提供特质激活线索, 调节“特质&;#8722;工作结果”关系, 如任务水平的工作控制、群体水平的领导行为以及组织水平的领导&;#8722;成员交换(LMX)关系等。情境相关性研究在人才选任、绩效管理、改善生产等方面起到积极作用。     

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.     

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.

如何建立聊天机器人与用户间的数字治疗联盟：关系线索的作用

近年来,研究者们将“治疗联盟”(Therapeutic Alliance,TA)的概念与在线自助干预(Internet-based Self-help Interventions,ISIs)相结合,以解决ISIs中用户参与度较低的问题。这种在数字环境中形成的TA,被称之为“数字治疗联盟”(Digital Therapeutic Alliance, DTA)。随着人工智能的迅速发展,聊天机器人可模拟人类指导,相对于传统ISIs程序更易于与用户建立关系,可通过友好、尊重、倾听、鼓励、真诚、理解、信任这几个关系线索来促进DTA的发展,为解决用户低参与度的问题提供了一种新思路。未来的研究可从影响因素、ISIs技术迭代、测量规范、实验操纵等方面对DTA作进一步的探索。
