Women’s sexual competition and the Dark Triad

The Dark Triad (DT) of sub-clinical narcissism, Machiavellianism, and psychopathy has been found to be related to competitive attitudes and behaviors, chiefly in men. Using a women-only sample (n = 439), we examined the relationship of DT with general and sexual competitiveness. Factor analysis indicated that the distinction between inter- and intra-sexual competition in women may be less clear than previously conceptualized. We found significant positive correlations between DT and both general and sexual competitiveness. Regression analyses indicated that DT, and in particular, narcissism, are significant predictors of general and sexual competitiveness. These findings are discussed in relation to evolutionary theory, and directions for future work on sexual competition and DT are suggested.     

Older sisters and younger brothers: The impact of siblings on preference for competition

Psychology studies have long argued the possibility that sibling structure, such as birth order and the sex of siblings, shapes one’s personality traits. One of the core issues involved is that of who rates subjects’ personality traits in studies. The present studies (N = 135 in Study 1, N = 232 in Study 2) surpassed the examinations performed in previous studies by obtaining information regarding one of the key personality traits, preference for competition, using a framework developed via experimental economics rather than subjective ratings. Despite the fact that the two studies involved different types of task, we consistently observed that older sisters exerted a significant impact on their younger siblings in both studies. In particular, having an older sister was negatively associated with men’s competitive preferences. We also obtained suggestive evidence that having an older sister was positively associated with women’s competitive preferences. Our results support sibling hypotheses from the perspective of experimental economics.     

Interaction Between Phonological and Semantic Representations: Time Matters

Computational modeling and eye‐tracking were used to investigate how phonological and semantic information interact to influence the time course of spoken word recognition. We extended our recent models (Chen & Mirman, 2012; Mirman, Britt, & Chen, 2013) to account for new evidence that competition among phonological neighbors influences activation of semantically related concepts during spoken word recognition (Apfelbaum, Blumstein, & McMurray, 2011). The model made a novel prediction: Semantic input modulates the effect of phonological neighbors on target word processing, producing an approximately inverted‐U‐shaped pattern with a high phonological density advantage at an intermediate level of semantic input—in contrast to the typical disadvantage for high phonological density words in spoken word recognition. This prediction was confirmed with a new analysis of the Apfelbaum et al. data and in a visual world paradigm experiment with preview duration serving as a manipulation of strength of semantic input. These results are consistent with our previous claim that strongly active neighbors produce net inhibitory effects and weakly active neighbors produce net facilitative effects.     

Overshadowed cues have reduced ability to retroactively interfere with other cues

The present series of experiments explores the interaction between retroactive interference and cue competition in human contingency learning. The results of two experiments show that a cue that has been exposed to a cue competition treatment (overshadowing) loses part of its ability to retroactively interfere with responding to a different cue that was paired with the same outcome. These results pose problems for associative models of contingency learning and are also difficult to explain in terms of current theories of causal reasoning. Additionally, it is proposed that in light of the interaction between interference and cue competition, interference could be used as an indirect measure for the study of cue competition effects.     

Psychoendocrine and physical performance responses in male Tunisian rugby players during an international competitive season

The aim was to investigate a follow-up study based on hormonal, physical, and psychological parameters among rugby players who trained during a whole season interspersed with competitions on an international level. Fitness or reciprocally tiredness as well as competitive anxiety were evaluated, respectively, using the French Society for Sports Medicine (SFMS) and the sport competition anxiety test (SCAT) questionnaires. In this study, SFMS and SCAT scores increased respectively over the competitive season. The SFMS score revealed a state of relative tiredness at the end of the season, highlighted by a slight decrement in physical performances. The SCAT score changes are related to the competition context and therefore increased accordingly to the importance of the competition stake. We analyzed the corticotrope and the gonadotrope axis before (T(1)), and at the end of the national and international rugby season (T(2)). Training did not affect the resting salivary cortisol (Csal) levels, but induced a decrease in resting testosterone (Tsal) values, resulting in a dropped T/C ratio. Competition, in both periods (T(1)-T(2)), provoked a significant increase in Csal levels, but the Tsal responses depended on the match stake. Their concentrations increased when the competition generated an important stress and decreased when the psychological conditions remained relatively stable. SFMS is preferentially correlated with resting Csal levels and T/C values measured at 08:00 hr but not with Tsal. SCAT is highly correlated with competitive Csal and Tsal concentrations measured before and after the matches.     

运动员的自我控制：重要理论及研究进展

摘要 运动员大赛最佳竞技表现的核心是良好的自我控制。本文介绍了解释自我控制与竞技表现关系的6个理论的核心要点和实证研究,包括自动执行假说（Baumeister, 1984）、加工效能理论（Eysenck & Calvo, 1992）、注意控制理论（Eysenck, Derakshan, Santos, & Calvo, 2007）、自我控制的力量模型（(Baumeister, Bratslavsky, Muraven, & Tice, 1998; Baumeister, Vohs , & Tice, 2007）、心理控制的逆过程理论（Wegner, 1994）和流畅状态理论（Csikszentmihalyi, 1990）;还介绍了通过心理训练以提高运动员自我控制能力的4个理论,包括心理建设综合模式（刘淑慧,1998,2001）、逆境应对训练模式（姒刚彦,2006,2007）、心理技能训练模型（Vealey, 2007）和中国运动员心理建设系统（张凯,张力为,2011）。本文讨论了这两类10个理论的异同及在运动员自我控制研究中的意义;最后指出,对不同的自我控制理论同时进行检验和比较的研究或许具有潜在价值。 关键词 自我控制,心理训练,运动员,比赛     

关于过度医疗的经济学分析与伦理

近年来,过度医疗问题引起医学伦理学界的普遍关注。过度医疗不仅是一个伦理问题,同时也是一种经济现象。过度医疗的经济学表现是医生诱导需求,直接成因是缺乏弹性的医疗需求,存在的市场环境是垄断竞争。遏止过度医疗需采取相应的伦理与经济对策。     

Secular Tolerance? Anti‐Muslim Sentiment in Western Europe

The literature about secularization proposes two distinct explanations of anti‐Muslim sentiment in secularized societies. The first theory understands it in terms of religious competition between Muslims and the remaining minority of orthodox Protestants; the second understands it as resulting from value conflicts between Muslims and the nonreligious majority. The two theories are tested by means of a multilevel analysis of the European Values Study 2008. Our findings indicate that, although more secularized countries are on average more tolerant towards Muslims and Islam, strongest anti‐Muslim attitudes are nonetheless found among the nonreligious in these countries.     

二语句法加工的认知机制、影响因素及其神经基础

二语(L2)和母语(L1)在句法加工方面的差异是量的不同还是质的表现？当前, 该问题已成为语言认知领域研究的热点。研究表明, 二语句法加工受到二语习得年龄、语言熟练度、工作记忆、二语习得方式等因素的影响。有关二语句法加工的理论主要有浅层结构假说、D/P模型和统一竞争模型。未来研究应注重探讨二语句法加工中二语熟练度及二语习得年龄的交互效应, 同时也应当加强儿童二语句法加工能力的研究。
