What do you think I think you think?: Strategic reasoning in matrix games

In reasoning about strategic interpersonal situations, such as in playing games, an individual's representation of the situation often includes not only information about the goals and rules of the game, but also a mental model of other minds. Often such mental models involve a hierarchy of reflexive reasoning commonly employed in social situations ("What do you think I think you think..."), and may be related to the developmental notion of 'theory of mind'. In two experiments, the authors formally investigate such interpersonal recursive reasoning in college-age adults within the context of matrix games. Participants are asked to predict the moves of another player (experimenter's confederate) in a two-choice, sequential-move game that may terminate at various stages with different payoffs for each player. Participants are also asked to decide optimally on their own moves based on the prediction made. Errors concerning the prediction, or translation of those predictions into decisions about one's action, were recorded. Results demonstrate the existence of a "default" mental model about the other player in the game context that is dynamically modified as new evidence is accumulated. Predictions about this other player's behavior are, in general, used consistently in decision-making, though the opponent tends to be modeled, by default, to behave in a myopic fashion not anticipating the participant's own action.     

Work-group characteristics and performance in collectivistic and individualistic cultures

The authors conducted a cross-cultural longitudinal investigation of the effects of culture (individualism-collectivism dichotomy) on group characteristics (functional heterogeneity, preference for teamwork, group potency, outcome expectation) and on performance of 83 work groups performing 2 decision-making tasks over a 15-week period. The individualists (U.S. students) reported higher levels of functional heterogeneity and group potency and attained higher levels of group performance than did the collectivists (Korean students). In addition, culture and time interacted to influence ratings of group potency and outcome expectation. The difference in ratings of group potency between individualists and collectivists increased over time. Outcome expectation was greater among the collectivists in Time 1 and among the individualists in Time 2. The authors discuss implications for future cross-cultural group research and international management.     

Adaptive self-regulation: meeting others' expectations of leadership and performance

The authors used longitudinal multisource field data to examine core aspects of the adaptive self-regulation model (A. S. Tsui & S. J. Ashford, 1994) in terms of linkages between self-monitoring, discrepancy in manager match-to-position, 5 measures of leadership, and manager performance. At Time 1, 64 superiors of focal managers rated the managers' matches to their positions within the organization; at Time 3, they rated the managers' performance. At Time 2, the 64 focal managers completed a measure of self-monitoring, and 192 subordinates rated the focal managers' leadership behaviors. Results of partial least squares analysis revealed that discrepancy in manager match-to-position was associated with reductions in laissez faire and passive management-by-exception behaviors and increases in transformational leadership behavior. Self-monitoring was positively associated with all 5 leadership behaviors. Performance was related positively to transformational leadership behavior and negatively to passive management-by-exception and contingent-reward behaviors     

An introduction to Bayesian hierarchical models with an application in the theory of signal detection

Although many nonlinear models of cognition have been proposed in the past 50 years, there has been little consideration of corresponding statistical techniques for their analysis. In analyses with nonlinear models, unmodeled variability from the selection of items or participants may lead to asymptotically biased estimation. This asymptotic bias, in turn, renders inference problematic. We show, for example, that a signal detection analysis of recognition memory data leads to asymptotic underestimation of sensitivity. To eliminate asymptotic bias, we advocate hierarchical models in which participant variability, item variability, and measurement error are modeled simultaneously. By accounting for multiple sources of variability, hierarchical models yield consistent and accurate estimates of participant and item effects in recognition memory. This article is written in tutorial format; we provide an introduction to Bayesian statistics, hierarchical modeling, and Markov chain Monte Carlo computational techniques.     

Development and validation of an altruism scale for adults

A new self-report scale, the Altruism Scale for Adults, of 28 items was developed. 14 items were from the Altruism subscale of Wrightsman's Philosophies of Human Nature Scale, and the other 14 items were newly constructed. The scale, anchored by 1: true or 2: false, was administered to 592 Korean men and women in eight subgroups. Cronbach alpha internal consistency was .89, and test-retest reliabilities (n = 52) over 1 and 5 wk. were .90 and .80, respectively. Campbell and Fiske's 1959 multitrait-multimethod analysis showed satisfactory convergent and discriminant validities. Overall results were promising for use of the scale in research and for practical purposes.     

中小学生对父母管教信息的认知、情绪与行为反应倾向

运用情境模拟的方法,对中小学生对父母管教信息的认知、情绪与行为反应倾向进行了研究。被试是616名中小学生。结果表明：(1)小学中年级以上学生对家长管教信息的情绪有较准确的认知;(2)不同管教信息的教育效能有优劣之分：诱导教诲最能引起被试的正面反应,其次是困扰担忧,伤心失望能引起部分学生的顺从反应,愤怒批评易引起子女的消极情绪和对抗行为。(3)父亲发出的管教信息比母亲更具权威性,更易引起子女积极的情绪体验与行为倾向。(4)学生对家长管教信息的反应具有明显的年龄和性别差异,小学生比中学生更易接受、顺从家长管教,女生比男生易产生更多的积极情绪与服从行为。(5)被试的认知评价与其情绪反应、行为倾向有较高的一致性。学生对父母管教信息的情绪体验和行为反应很大程度上取决于对管教信息的认知。如果学生的认知较为积极,更易引起积极的情绪体验和行为倾向。     

现行《医疗事故处理办法》的修改探析

现行《医疗事故处理办法》颁布实施１０ 年之久,新形势下需要对其进行修改和完善。“办法”的修改应该体现平等保护医患双方合法权益原则,合理界定医疗事故范围,调整医疗事故鉴定委员会的组成,建立完善的证据管理制度,明确医疗事故损失赔偿的范围和额度。     

辩证分析兴奋性氨基酸对神经细胞的双重作用

兴奋性氨基酸（ＥＡＡｓ） 广泛分布于中枢神经系统,参与多种生理过程包括学习、记忆和伤害感受等。然而,ＥＡＡｓ 受体的过度兴奋却可引发一系列细胞事件,最终导致神经元的损伤与死亡。许多神经退行性疾病如早老性痴呆、癫痫和肌侧索硬化症等都与ＥＡＡｓ 的兴奋毒作用有关。目前的研究表明,由ＥＡＡｓ 受体过度兴奋所引发的细胞内钙超载是导致神经元死亡的最终途径     

Bidirectional semantic associations between social power and weight

Two experiments were conducted to examine bidirectional semantic associations between power and weight using a priming paradigm. Bidirectionality in the relationship between power and weight was demonstrated, utilising tasks that were identical except that the orders in which the stimuli were presented were reversed. In Experiment 1, an empty scale leaning either leftward or rightward was used as a priming stimulus, and a scale that appeared in equilibrium with a pair of power words was used as a target stimulus. In Experiment 2, a scale with a pair of words that appeared in equilibrium was used as a priming stimulus, and an empty scale leaning either leftward or rightward was used as a target stimulus. We identified interaction effects between power and weight in both experiments. Associations between power and weight provide evidence for both conceptual metaphor views and evolutionary theory. The bidirectionality of metaphorical effects is in line with the strong version of metaphoric structuring. Both language and experiential correlations play important roles in the development of the mapping between power and weight.     

Contesting Chineseness: An Examination of Religion and National Identity in Mainland China

For citizens of many countries around the world, religion is a necessary—though often contested—component of their national identity. From the vantage point of the symbolic boundaries approach, we argue that the Chinese government and various other social actors are in contestation to define “Chineseness” in religious terms. Using data from the 2007 Spiritual Life Study of Chinese Residents, this study explores the extent to which religion functions as a constitutive part of Chinese national identity. We find that the effectiveness of the Chinese government's demarcation of the symbolic boundaries around Chineseness related to religion varies across religious groups. Believers of each religion are likely to be strong advocates for their own religion's connection to Chinese national identity. Among the religions, traditional Chinese religions tend to demonstrate a stronger affinity with one another than with Christianity. Daoists are a particularly strong contestant in aligning Daoism with Chineseness, to the extent that they discredit the other religions’ suitability for the Chinese. We discuss the implications of these findings and point out directions for future research.
