RELIGION AND RELIGIOUS BELIEFS AS EVOLUTIONARY ADAPTATIONS

Scholars employing an evolutionary approach to the study of religion and religious beliefs search for ultimate explanations of the origin, propagation, and persistence of religious beliefs. This quest often pairs in debate two opposing perspectives: the adaptationist and “by‐product” explanations of religion and religious beliefs. The majority of scholars prefer the by‐product approach, which is agnostic and even doubtful of the usefulness of religious beliefs. Despite this pervasive negativity, it seems unwarranted to deny the great usefulness of religious beliefs—particularly concerning their past utility. Instead, adaptationist explanations of religion and religious beliefs must be re‐established as interesting and useful approaches to the study of religious beliefs.     

儿童资源获取行为对学校适应的影响——一个历时5年的跨文化追踪

以160名中国儿童和133名加拿大儿童为被试,采用实验室观察和问卷调查,考察儿童7岁时的资源获取行为对其11岁时学校适应的影响。结果表明：（1）轮流规则行为对儿童的学校适应具有消极的预测作用,且存在性别差异：男孩的轮流规则行为可以显著正向预测其焦虑,女孩的轮流规则行为可以显著负向预测其学校态度;（2）请求行为可以显著正向预测中国儿童攻击行为,加拿大儿童则没有发现该关系;（3）对于资源获取失败次数少的儿童,求助成人行为有积极的适应意义;（4）儿童资源获取行为的结果在儿童7岁时资源获取行为与11岁时学校适应之间发挥调节作用;对于资源获取成功次数少的儿童,请求行为可以显著地正向预测其攻击行为;对于资源获取失败次数少的儿童,请求行为则显著地负向预测其攻击行为,求助成人行为可以显著地负向预测其孤独感。     

Performance feedback,self-esteem,and cardiovascular adaptation to recurring stressors

Background and Objectives: This study sought to examine the effects of performance feedback and individual differences in self-esteem on cardiovascular habituation to repeat stress exposure.

Methods: Sixty-six university students (n?=?39 female) completed a self-esteem measure and completed a cardiovascular stress-testing protocol involving repeated exposure to a mental arithmetic task. Cardiovascular functioning was sampled across four phases: resting baseline, initial stress exposure, a recovery period, and repeated stress exposure. Participants were randomly assigned to receive fictional positive feedback, negative feedback, or no feedback following the recovery period.

Results: Negative feedback was associated with a sensitized blood pressure response to a second exposure of the stress task. Positive feedback was associated with decreased cardiovascular and psychological responses to a second exposure. Self-esteem was also found to predict reactivity and this interacted with the type of feedback received.

Conclusions: These findings suggest that negative performance feedback sensitizes cardiovascular reactivity to stress, whereas positive performance feedback increases both cardiovascular and psychological habituation to repeat exposure to stressors. Furthermore, an individual’s self-esteem also appears to influence this process.     

Identity-specific face adaptation effects: evidence for abstractive face representations

The effects of selective adaptation on familiar face perception were examined. After prolonged exposure to photographs of a celebrity, participants saw a series of ambiguous morphs that were varying mixtures between the face of that person and a different celebrity. Participants judged fewer of the morphs to resemble the celebrity to which they had been adapted, implying that they were now less sensitive to that particular face. Similar results were obtained when the adapting faces were highly dissimilar in viewpoint to the test morphs; when they were presented upside-down; or when they were vertically stretched to three times their normal height. These effects rule out explanations of adaptation effects solely in terms of low-level image-based adaptation. Instead they are consistent with the idea that relatively viewpoint-independent, person-specific adaptation occurred, at the level of either the “Face Recognition Units” or “Person Identity Nodes” in Burton, Bruce and Johnston’s (1990) model of face recognition.     

父母支持与服刑青少年的情绪适应:公正世界信念的中介作用

以446名服刑青少年为被试,采用问卷法,探讨了青少年服刑后的父母支持、公正世界信念与其情绪适应的关系及作用机制。结果表明:(1)服刑青少年的情绪适应状况较差,抑郁水平较高,生活满意度较低;(2)服刑后的父母支持和公正世界信念显著负向地预测青少年的抑郁,显著正向地预测其生活满意度;(3)公正世界信念在父母支持和抑郁、生活满意度之间均起着部分中介作用。这表明,服刑后青少年的父母支持既可以直接促进其服刑期间的情绪适应,又可以通过提升其公正世界信念来促进其服刑期间的情绪适应。     

Neural circuitry of the bilingual mental lexicon: Effect of age of second language acquisition

Numerous studies have proposed that changes of the human language faculty caused by neural maturation can explain the substantial differences in ultimate attainment of grammatical competences between first language (L1) acquirers and second language (L2) learners. However, little evidence on the effect of neural maturation on the attainment of lexical knowledge in L2 is available. The present functional magnetic resonance study addresses this question via a cross-linguistic neural adaptation paradigm. Age of acquisition (AoA) of L2 was systematically manipulated. Concrete nouns were repeated across language (e.g., French–German, valise^suitcase–Koffer^suitcase). Whereas early bilinguals (AoA of L2 < 3 years) showed larger repetition enhancement (RE) effects in the left superior temporal gyrus, the bilateral superior frontal gyrus and the right posterior insula, late bilinguals (AoA of L2 > 10 years) showed larger RE effects in the middle portion of the left insula and in the right middle frontal gyrus (MFG). We suggest that, as for grammatical knowledge, the attainment of lexical knowledge in L2 is affected by neural maturation. The present findings lend support to neurocognitive models of bilingual word recognition postulating that, for both early and late bilinguals, the two languages are interconnected at the conceptual level.     

Self-denial and the role of intentions in the attribution of agency

The ability to distinguish between our own actions and those of an external agent is a fundamental component of normal human social interaction. Both low- and high-level mechanisms are thought to contribute to the sense of movement agency, but the contribution of each is yet to be fully understood. By applying small and incremental perturbations to realistic visual feedback of the limb, the influence of high-level action intentions and low-level motor predictive mechanisms were dissociated in two experiments. In the first, participants were induced to claim agency over movements that were subject to large perturbations and to deny agency over self-produced unperturbed movements despite the application of motor corrections by low-level mechanisms. A control experiment confirmed that if reaches met with their intended goal then they were more likely to be attributed to the agent, regardless of the discrepancy between the actual and seen positions of the limb.

目的研究分析"90后"大一新生心理适应能力及心理健康状况,为更好地开展"90后"大一新生的心理健康教育工作提供依据。方法采用心理适应能力问卷和症状自评量表(SCL-90)对四川大学和四川师范大学2009级800名新生进行调查。结果①有54.9%的学生心理适应能力较差,仅有3.3%的学生有较强的心理适应能力;②"90后"大一新生的心理健康水平总体低于全国青年常模,除躯体化和敌对因子外,其它因子得分显著高于常模(P0.05);③不同心理适应能力的"90后"大一新生在SCL-90各个维度上均存在显著差异(P0.05),但性别比较时,只在恐怖因子上存在显著差异(P0.05)。结论"90后"大一新生心理健康状况不容忽视,学校应结合"90后"学生的特点,加强心理健康教育,提高"90后"大一新生的心理适应能力及心理健康水平。     

The Operational Codes of Fidel Castro and Kim Il Sung: The Last Cold Warriors?

Although the end of the Cold War brought the transformation of the communist bloc, some states have resisted the ensuing wave of democratization. This study assumes that important mechanisms of continuity and change in communist states are situated in the belief systems of their leaders and that the years between 1985 and 1991 were a catalytic period. What did Fidel Castro of Cuba and Kim Il Sung of North Korea learn from the end of the Cold War? Their belief systems are examined prior to 1985 and after 1991, i.e., before and after the collapse of other communist regimes. If learning has occurred, it should be reflected in a comparison of their beliefs for these time periods. Our results from ANOVA analyses indicate that Fidel Castro engaged in some learning but Kim Il Sung did not. This finding is complemented by the results of a MANOVA analysis, which indicate that the end of the Cold War had only a modest impact on Fidel Castro and Kim Il Sung, independent of their specific personalities. We conclude by drawing attention to the ensuing debate between structural‐ and agent‐level theorizing and by giving some suggestions for future research.
