心算加工年老化及其机制研究

以１７２名２０－７９岁成人为被式对心算加工的年老化过程及其机制进行了研究。任务为连续减法心算,依难度分为５种：１０００－１,１０００－３,１０００－１３及１０００－１７。结果表明,年龄与心算难度存在明显的交互作用,且随着年龄增加,不同难度心算效率均以幂函数形式降低。     

心算活动机制的研究

心算是一种重要的思维活动,是认知心理学的研究主题之一。心算活动具有明显的问题大小效应,其加工过程与工作记忆和长时记忆存在密切关系。此外,对心算的加工机制进行跨学科（认知心理学、神经科学等）的综合研究,是今后心算研究的主要方向。     

心算加工年老化及其机制研究

以172名20－79岁成人为被试对心算加工的年老化过程及其机制进行了研究。任务为连续减法心算,依难度分为5种：1000－1、1000－3、1000－7、1000－13及1000－17。结果表明,年龄与心算难度存在明显的交互作用,且随着年龄增加,不同难度心算效率均以幂函数形式降低。结构方程建模分析发现心算加工年老化过程存在两个中介作用因子,即速度因子和非速度因子,且速度因子对非速度因子存在明显的正效应。

伪医学国际化之成因

伪医学的表现形式多种多样,且存在于世界的各个角落,功利思想的驱动、职业道德的沦丧,使传播者见利忘义;医学水平的局限、本能的求生意识诱发了人们求助伪医学的侥幸心理;医巫同源的影响、伪医学的心理调控作用模糊了人们对其本质的认识;贫困者对现代医疗费用的畏惧、富有者对健康长寿的奢望为伪医学提供了广阔的市场;文化差异的存在,使伪医学拥有了生长的土壤

Relations between social comparison orientation and adjustment in Chinese adolescents: Moderating effects of initial adjustment status

This 1‐year longitudinal study examined relations between social comparison orientation (SCO) and socioemotional adjustment and academic achievement. A sample of Grades 7 and 8 students (N = 336, initial M age = 14.08 years) in China participated in the study. Data were collected from self‐reports, peer assessments and school records. It was found that early SCO positively contributed to later academic achievement. Moreover, the relations between early SCO and later socioemotional adjustment were moderated by the initial status of adolescents. Specifically, SCO was positively associated with social competence and negatively associated with depression in initially competent and well‐adjusted adolescents, but the pattern of the associations was opposite in initially incompetent and poorly adjusted adolescents. The results indicate that whereas SCO may contribute directly to academic achievement, its contributions to socioemotional development might depend on adolescents' initial status in adjustment.     

Risk and Prisoner's Dilemma: A Reinterpretation of Coombs' Re‐parameterization

We propose a model to measure risk in a prisoner's dilemma based on Coombs' (1973) re‐parameterization of the game as an individual risk decision‐making task that chooses between a gamble of cooperation and another gamble of defection. Specifically, we propose an index, r, to represent the risk associated with cooperation relative to defection. In conjunction with Rapoport's (1967) index of cooperation (K), our formulation of risk allows us to construct games that vary in risk (as indexed by r) while controlling for cooperativeness (as indexed by K). Following utility analysis that models risk seeking as a convex utility function and risk averse as a concave function, we predict that risk‐seeking people cooperate more in games that the cooperation choice is more risky, whereas risk‐averse people cooperate more in games that the cooperation choice is less risky. In the three studies that we varied game parameters, used different measures of risk orientation and prosocial orientation and used different experimental procedures, we found robust results supporting our predictions. Theoretical analysis of our formulation further suggests that risk and cooperativeness of a prisoner's dilemma game is not entirely independent. Games that have a higher cooperativeness index are necessarily more risky. Copyright © 2011 John Wiley & Sons, Ltd.     

Communication behavior and relationship satisfaction among American and Chinese newlywed couples

Most research on couple communication patterns comes from North America and Europe and suggests cross-cultural universality in effects, but emerging studies suggest that couple communication takes different forms depending on the cultural context in which it occurs. The current study addressed this discrepancy by comparing the observed social support behaviors of 50 newlywed American couples and 41 newlywed Mainland Chinese couples, first on mean levels of positivity and negativity and second on behavior-satisfaction associations. Consistent with predictions derived from observational work by Tsai and Levenson (1997), Chinese couples were observed displaying significantly more negative behavior than American couples, even after controlling for relationship satisfaction; the 2 groups did not differ in observed positive behaviors. Tests of the moderating role of culture on behavior-satisfaction associations showed that positivity was significantly related to relationship satisfaction only for American husbands, whereas negativity was significantly associated with relationship satisfaction only for Chinese husbands. We speculate that cultural contexts may influence the display and evaluation of behavior in intimate relationships, suggesting the need for caution when generalizing models and associated interventions to non-Western couples.
