Religiosity and fear of death: a three‐nation comparison

Numerous studies have sought to determine if religiosity is correlated with fear of death. Findings have been anything but consistent, with reports of negative relationships, positive relationships, no relationship, and even curvilinear associations. To shed light on this still contentious issue, the present study was undertaken among college students in three countries – Malaysia, Turkey, and the United States. Overall, the patterns in all three countries were similar. When linearity was assumed, there is a substantial positive correlation between most religiosity measures and fear of death. Assuming curvilinearity added slightly to the strength of the relationships in the US data and nothing to data from Malaysia or Turkey. Other findings were that on average females were more religious and feared death more than did males, and Muslims expressed considerably greater fear than did members of any other major religion. Results were discussed in the context of a new theory – called death apprehension theory. Among other things, it specifically predicts that death apprehension will be positively related to most religious beliefs and practices.     

A brief review on the use of functional near-infrared spectroscopy (fNIRS) for language imaging studies in human newborns and adults

Upon stimulation, real time maps of cortical hemodynamic responses can be obtained by non-invasive functional near-infrared spectroscopy (fNIRS) which measures changes in oxygenated and deoxygenated hemoglobin after positioning multiple sources and detectors over the human scalp. The current commercially available transportable fNIRS systems have a time resolution of 1-10 Hz, a depth sensitivity of about 1.5 cm, and a spatial resolution of about 1 cm. The goal of this brief review is to report infants, children and adults fNIRS language studies. Since 1998, 60 studies have been published on cortical activation in the brain’s classic language areas in children/adults as well as newborns using fNIRS instrumentations of different complexity. In addition, the basic principles of fNIRS including features, strengths, advantages, and limitations are summarized in terms that can be understood even by non specialists. Future prospects of fNIRS in the field of language processing imaging are highlighted.     

Thinking ahead or not? Natural aging and anticipation during reading

Despite growing evidence of young adults neurally pre-activating word features during sentence comprehension, less clear is the degree to which this generalizes to older adults. Using ERPs, we tested for linguistic prediction in younger and older readers by means of indefinite articles (a’s and an’s) preceding more and less probable noun continuations. Although both groups exhibited cloze probability-graded noun N400s, only the young showed significant article effects, indicating probabilistic sensitivity to the phonology of anticipated upcoming nouns. Additionally, both age groups exhibited prolonged increased frontal positivities to less probable nouns, although in older adults this effect was prominent only in a subset with high verbal fluency (VF). This ERP positivity to contextual constraint violations offers additional support for prediction in the young. For high VF older adults, the positivity may indicate they, too, engage in some form of linguistic pre-processing when implicitly cued, as may have occurred via the articles.     

TELEOLOGY IN BIOLOGY: WHO COULD ASK FOR ANYTHING MORE?

Abstract. Teleological thinking permeates biology and is useful in pondering unanswered biological questions. Such thinking differs from the usual sense of teleology in that “purpose” in biology carries no imputation of causation. A few examples are given. The teleological system of biology is every bit as elegant a construct of the human mind as any other teleological system and in no way precludes spirituality. I argue that it provides a firmer foundation for moral guidance than supernatural systems.     

脑内移植发展的回顾和展望

脑内移植是神经系统疾病的一种新的治疗措施。它适应临床实践的需要而产生,历经脑内组织移植和脑内干细胞移植两个重要发展阶段,其中脑内干细胞移植的研究主要有神经干细胞移植、胚胎干细胞移植、骨髓和脐血间充质干细胞移植。脑内干细胞移植是目前国内外医学研究的热点,具有广阔的临床应用前景,但也存在许多有待解决的问题,还需要经过一个艰难曲折的探索过程,最终使之成为治疗神经系统疾病的有效方法。它的产生和发展遵循着认识论和辩证法的客观规律,体现了科学认识的实践性、深刻性和创造性。     

朴素物理观和朴素心理观--进化心理学视角

人类在进化过程中解决生存与繁衍问题需要适应物理环境和社会环境。进化心理学认为人类适应物理环境与社会环境的心理机制分别称为朴素物理观和朴素心理观。文章首先阐述了朴素物理观和朴素心理观的有关内容,并指出两性差异的一个重要方面在于移情和系统化的不同组合,同时对其进化意义做了分析。     

情绪对认知加工的影响：事件相关脑电位系列研究

为探讨情绪与认知的相互作用关系及其脑机制,建立了情境图片、面孔、汉字和声音四个系列组成的中国情感刺激材料库,并通过ERP实验对情绪与注意、工作记忆的关系以及特质焦虑者的认知特点进行了研究。结果发现：⑴ 负性情绪刺激在信息加工过程中至少在注意、评价及反应准备这几个阶段具有某种优先权,注意偏向也可在内隐任务下发生,负性刺激对注意资源不足具有某种补偿作用;⑵ 威胁性视觉提示对其后的视觉加工具有调节作用,高焦虑个体对这类性刺激投入了更多的视觉加工资源,而且威胁性刺激对注意的影响可以跨通道进行,威胁性的视觉刺激可以影响触觉注意;⑶ 在情绪对工作记忆的影响方面,负性情绪下空间工作记忆任务引起的P300波幅减小,这种效应可能是基于情绪对顶叶注意系统的调节作用,而在词语工作记忆任务中这种效应消失     

浅析死刑认同的心理根源

我国民众普遍认同死刑,这种"死刑认同"具有三种心理情绪根源:死亡情结、社会情感以及正义报复感。死刑认同实质上是国民的一种个人情绪和社会情感的表达和要求。取消死刑是必然趋势,但必须具备相应的社会条件。     

反社会行为的遗传基础:基因多态性和DNA甲基化

反社会行为是受遗传与环境共同影响的不良行为。分子遗传学和神经生物学的研究发现,基因以基因多态性和DNA甲基化的方式影响脑结构、功能及脑内神经递质的产生和释放,进而影响反社会行为的发生发展。本文从基因多态性和DNA甲基化两方面整理了5-HTT、MAOA、OXTR等8个候选基因与反社会行为的关联。并提出未来研究需进一步探讨基因、脑和神经递质对反社会行为的联合作用。同时,扩展多基因位点、基因多态性与DNA甲基化、积极环境与基因交互作用对反社会行为影响的研究,以全面探索反社会行为发生的遗传基础,进而更加有效的预防反社会行为。
