控制幻觉的研究方法、形成机制和影响因素

控制幻觉是指在完全不可控或部分不可控的情境下, 个体由于不合理地高估自己对环境或事件结果的控制力而产生的一种判断偏差。控制幻觉普遍存在于博彩游戏、医疗保健、心理健康、投资决策等实践领域。控制幻觉的研究方法主要包括间接测量方法、自我报告方法和实验室任务方法。控制启发式理论和调节定向理论则对控制幻觉的产生原因进行了解释。控制幻觉的影响因素包括人格因素、动机、权力、反馈、事件与个体的关联性、指导语等。未来的研究可从控制幻觉的多变量及交互作用研究、跨文化研究、调控策略研究等方面做进一步探讨。     

重读与信息结构对语篇理解加工的影响

该研究利用口语动窗技术和双重任务范式,探索了重读与信息结构的匹配关系对语篇理解加工的影响、以及其发挥作用的内部机制。结果表明：与控制条件相比,不一致性重读阻碍语篇的理解加工,而一致性重读对语篇理解的促进作用相对不明显;重读促进焦点词汇的加工,而不重读促进非焦点词汇的加工,从而说明重读影响语篇理解不仅仅是由于它能调控听者的注意力分配,更重要的是重读的有无传达着不同的信息加工方式。     

按病种支付医疗保险费用与病种成本核算研究

医疗服务具有垄断性、委托代理双重性和需求刚性.在利益机制驱动下,医疗项目的选择变成供方偏好,是医疗费用快速攀升的症结之一.变按项目支付为按病种支付,是控制医疗费用快速上涨、深化卫生改革的重要措施之一.最科学的方法是进行病种成本核算.     

修饰语的焦点和重音对话语理解的影响

本研究分别采用韵律合适度判断和理解任务,通过两个实验探讨修饰语的焦点和重音之间的关系对话语理解的影响。实验通过操纵答句中的论元是否出现在问句中,变化问句的信息状态;通过操纵答句的不同句子成份重读,变化答句的重读位置。实验结果发现：新的修饰语重读,旧的修饰语不重读;修饰语不投射焦点,即修饰语重读不将焦点投射到修饰语的中心语上。     

What's to Fear from Immigrants? Creating an Assimilationist Threat Scale

We argue that cultural threat, stressed in recent studies of anti-immigrant sentiment, is properly measured in the U.S. case as "assimilationist threat": a resentful perception that immigrants are failing to adopt the cultural norms and lifestyle of their new homeland. We explore the meaning and form of assimilationist threat in the minds of Americans through an analysis of four focus groups, two in Los Angeles, CA, and two in Columbus, OH. Using information from the focus groups, we develop and test a set of survey questions covering three dimensions of immigrants' commitment to their new country: language, productivity, and citizenship. We produce a summary scale of assimilationist threat that can be used by other researchers seeking to understand the causes and consequences of anti-immigrant sentiment.     

“Strength and Safety in Numbers”: A Theoretical Perspective on Group Influences on Approach and Avoidance Motivation

This paper presents a theoretical framework that advances current understanding of motivational and affective causes and consequences of small group processes and behaviors. Theories on the approach and avoidance systems of motivation state that these systems are active in the presence of potential positive or negative outcomes, respectively. In many instances, groups are associated with rewards and are perceived to facilitate positive outcomes (“strength in numbers”), and are a source of security and thought to reduce the occurrence of negative outcomes (“safety in numbers”). Accordingly, group membership and interaction should impact activation of group members’ approach and avoidance motivation systems. Thus, systematic group influences on mood, information processing, perceptions, attention, and behavior should be expected. The integration of approach and avoidance theories with small group research can potentially broaden our knowledge of the group experience, and lead to a theoretical framework for investigations of goal-directed behaviors in group settings.     

Risk and resilience: Dual effects of perceptions of group disadvantage among Latinos

Several decades of research on the psychology of minority status has yielded highly discrepant findings. Substantial research suggests that perceptions of discrimination are linked to inferior self-regard and poor mental health, whereas other studies indicate that perceptions of discrimination are protective of global self-esteem. We tested a theoretical model of the combined (negative/positive) effects of perceived group disadvantage on self-esteem among Latinos. Structural equation modeling analyses indicated that perceptions of group disadvantage were indirectly related to self-esteem through two principal pathways. The total (direct and indirect) effect on self-esteem was not significant, suggesting that, among Latinos, the deleterious consequences of perceived belonging to a devalued and disadvantaged group were fully counterbalanced by the positive effects of intervening variables. More complex models may be needed to characterize fully the self-protective and detrimental consequences of perceived group disadvantage among Latinos.     

长时记忆中目标信息的即时性通达

采用移动窗口技术和探测词再认技术,探讨文本阅读过程中长时记忆中目标信息的即时性通达。实验1探讨当原目标尚未实现,新目标处于活跃状态,进入长时记忆的未实现的原目标是否对当前阅读产生影响。实验2探讨当原目标已经实现,新目标处于活跃状态,进入长时记忆的已实现的原目标是否对当前阅读产生影响。本实验结果初步证明,在含有目标信息的文本阅读中,未实现的原目标信息和已实现的目标信息都处于活跃状态,一旦出现与原目标焦点有关的信息,就会被通达与当前的信息进行整合,只是已实现的目标信息比未实现的目标信息通达的程度低。     

Attention,mindwandering, and mood

We tested the hypothesis that mindwandering and external distraction are both manifestations of a common state of reduced attention focus, and examined how both relate to reported level of happiness. We conducted real-time sampling of people’s experience of mindwandering, irrelevant distraction (e.g. by music, phone, etc.), and happiness levels, in two studies with 524 people undertaking common daily-life activities. All irrelevant external distractions were positively correlated with mindwandering. Indeed mindwandering duration could be predicted from the reported duration of external distraction, when controlling for a range of background variables. An exploratory factor analysis of mindwandering and distraction reports suggested a single underlying construct. In addition, duration of irrelevant distraction by both mobile phones and mindwandering was significantly associated with reduced reported levels of happiness. The results are consistent with the hypothesis that that a state of reduced attention focus underlies both mindwandering and distractibility and clarify the link with happiness.     

Changing behaviors: Using norms to promote physical activity for type 2 diabetes patients

IntroductionGiven that diabetes is a major public heath issue around the world, it is vital that we find effective means to change behaviors, especially levels of physical activity among type 2 diabetes patients.ObjectiveThis study aims to provide proof of the effectiveness of programs promoting physical activity, based on cognitive dissonance and normative focus theories which are designed to produce behavioral changes in persons with type 2 diabetes.MethodNinety-six type 2 diabetes patients were assigned to one of three programs: a traditional information program, a norm-based program, and a dissonance-based program. The participants filled out a short French version of the International Physical Activity Questionnaire (IPAQ) one week before and one week after the program.ResultsThe results showed that the participants in the norm-based program made progress compared to those in the traditional information program. No significant difference was observed between the traditional information program and dissonance-based program.ConclusionsThese findings are consistent with both the focus normative theory and previous studies showing that recalling the norm increases compliance. The procedure to be used in diabetes prevention programs should focus on the normative dimensions of the desired behaviors in order to improve patients’ quality of life.
