频率差异假设和长时记忆的视优效应

本文包括长时记忆视优效应的三项实验。实验一使用汉语为学习材料,北京人与广东人为被试;实验二使用英语为学习材料、美国人与中国人为被试;实验三使用日语为学习材料、日本人为被试。三项实验都有视觉、听觉两种呈现方式。三项实验的结果都有利于证明频率差异假设,即如果在书面言语中经验某字词的频率高于在口语中经验该字词的频率,则该字词的视觉呈现优于听觉呈现。     

Individual differences in harm-related moral values are associated with functional integration of large-scale brain networks of emotional regulation

Emotions affects moral judgements, and controlled cognitive processes regulate those emotional responses during moral decision making. However, the neurobiological basis of this interaction is unclear. We used a graph theory measurement called participation coefficient (‘PC’) to quantify the resting-state functional connectivity within and between four meta-analytic groupings (MAGs) associated with emotion generation and regulation, to test whether that measurement predicts individual differences in moral foundations-based values. We found that the PC of one of the MAGs (MAG2) was positively correlated with one of the five recognized moral foundations–the one based on harm avoidance. We also found that increased inter-module connectivity between the ventromedial prefrontal cortex, dorsolateral prefrontal cortex and middle temporal gyrus with other nodes in the four MAGs was likewise associated with higher endorsement of the Harm foundation. These results suggest that individuals' sensitivity to harm is associated with functional integration of large-scale brain networks of emotional regulation. These findings add to our knowledge of how individual variations in our moral values could be reflected by intrinsic brain network organization and deepen our understanding of the relationship between emotion and cognition during evaluations of moral values.     

点评"开创内河浅水航道船舶运输新纪元"

从友人处寄来《科技日报》8月6日的上述文章,阅后令人吃惊。多年来全国造船界和航运界公认的“周锦宇超浅水船”伪科学,变成了“开创……船舶运输新纪元”的大发明,一堆堆废铁变成了大成果。这里就该文所涉及的几件事的真相,提供社会各界参考。一、文中说:周锦宇“提出了流体分子量质与物体运动相对瞬变新理论成因这一大胆设想,……是对流体力学研究的重大突破,……其作用是无可估量的”。对于连文句都不通的,没有任何说明的,不知所云的“一句话”理论,怎样突破?何来作用?二、文中说:“30吨级超浅水船畅通闽江上游。”事实是,1987年初福建省…     

关于“宗教与文化关系”问题的思考

近年来,关于＂宗教与文化关系＂问题的讨论引起人们的关注和议论,宗教文化的内涵是什么、怎样认识宗教与文化的关系、执政党如何对待和处理宗教与文化的关系问题……对这一涉及宗教工作的重要理论问题,还需要进一步从马克思主义宗教观角度进行较为深入系统的基础性研究。     

黄泉路上走来回

这是很多年以前的事了。一天,四弟的电话来了,说:“父病重已难医治,他在世时日不多,急着要向你交代后事。”如此我只好火速回故乡探父病。我一到父亲的病榻前,见父亲已瘦得皮包骨头,四弟说他已有数日不进食也不肯吃药。父亲见到我似乎要急着交代后事,他上气不接下气地说:“你母亲已经来看过我,我去阴司要同你母亲住一起,不愿和你继母住一起。你是老大,这事你须在我去黄泉路前办好。”故乡所处山区,1994年时这个县还没有搞丧葬改革,城乡一律是土葬,故父亲和继母早在和睦时已建寿坟。后来因父亲和继母感情不好而分居了。现在病重,提出要和母亲…     

荀子隆礼重法的政治思想是对儒家德治思想的创新发展

荀子"化性起伪"."隆礼重法"的政治思想是建立在他的性恶的人性论基石上的。以礼为本、德法并举、德主刑辅、礼义教化与法律强制相辅相成,是他政治思想的核心内容,也是其对儒家德治思想的创新发展。剔除其封建糟粕,它对我们今天建设和谐小康社会仍可提供有益的启示。     

The structure of traits delineating personality disorder in a Chinese sample

The present study examined the factorial structure of a Chinese language version of the self-report Dimensional Assessment of Personality Pathology Questionnaire in 581 adults. Four factors were extracted (Emotional Dysregulation, Dissocial, Inhibition, and Compulsivity) that are similar to the factors extracted in the scales' normative clinical and general population samples from North America (factor comparability coefficients range from .88 to .96), supporting the idea that this trait structure is invariant across diverse populations. The internal consistency of the scales (Cronbach's alpha) was satisfactory across age and gender groups with the exception of the Intimacy Problems scale. Possible explanations for the poor internal consistency of the Intimacy Problems scale, such as cultural differences in social factors influencing marital and romantic relationships in Chinese populations, as opposed to other populations are discussed.     

Hypoglycemia-induced suppression of luteinizing hormone (LH) secretion in intact female rhesus macaques: role of vasopressin and endogenous opioids

The first objective of this study was to determine whether insulin-induced hypoglycemia (IIH) inhibits LH secretion in unrestrained female macaques during the follicular phase of the menstrual cycle. There was a consistent inhibitory effect of hypoglycemia on LH secretion within 3 h in these females. This inhibition was likely an indirect effect since low glucose levels did not inhibit GnRH secretion from GT1-1 neurones in vitro. We next investigated whether administration of a vasopressin antagonist (AVPa) either alone, or with naloxone could reverse the IIH-induced inhibition of LH release. Females were studied in the follicular phase during 10 h periods with blood samples collected every 10 min. Experimental groups were IIH (n=6), IIH+AVPa (n=5) and IIH+AVPa+naloxone (n=4). The first 5 h of each study served as a control and hypoglycemia was then induced with insulin. The AVPa was given as a bolus (180 microg) just before the insulin and was followed by a continuous infusion (180 microg/h) for 5 h. Naloxone (5 mg/kg) was given with the AVPa and followed by a continuous infusion (5 mg/kg/h) for 5 h. In the IIH group, LH reached its lowest value 3-4 h after insulin. Neither AVPa nor AVPa+naloxone infusion reversed the inhibitory action of hypoglycemia on LH release. These data suggest that if there are inhibitory actions of vasopressin and endogenous opioids on GnRH release induced by hypoglycemia, they are not sufficient to explain the suppression of GnRH/LH release in intact female primates.

错误再认:意识、注意和刺激特性

该研究基于错误再认现象,确立了意识知觉和无意识知觉在行为结果上的质的差异。在决定一个刺激是被有意识知觉还是无意识知觉时,刺激特性和注意之间存在着相互补偿的作用。实验一表明,当一个刺激短暂呈现而被无意识知觉的时候,增强刺激特性或提高注意水平都能使它的知觉变为有意识的;相对应地,实验二表明,一个处于分散注意条件下被无意识知觉的刺激,也可以通过使注意集中或增强刺激特性而使它的知觉变为有意识的。该研究对意识、注意和刺激特性三者间的关系进行了讨论。
