多动症儿童的智力水平、行为与认知事件相关电位的研究

通过对多动症 (MBD)儿童的智力、行为和认知事件相关电位的分析研究,发现多动症儿童的智力水平正常但均数都低于正常儿童,行为问题的检出率和行为量表指数高于一般正常儿童,反映大脑认知功能的事件相关电位的N2、P3的潜伏期较之正常儿童组均延长,且差异均达到显著性水平。     

客体复杂度影响工作记忆可存储的客体数目

采用变化觉察范式,以对侧延迟活动（contralateral delay activity,CDA）的幅值为指标,通过操纵记忆刺激的复杂程度,对视觉工作记忆中可存储的客体数目（即工作记忆容量）问题进行了探讨。结果表明,2个复杂客体条件下的CDA幅值与4个复杂客体条件无显著差异,而4个简单客体条件的CDA幅值显著高于2个简单客体条件,即CDA的幅值受客体复杂度的调节。基于该结果推论：并非视觉工作记忆总能存储4个客体,其可存储的客体数目受客体复杂度影响。     

新中国六十年伦理学学科体系视阈下的十大争论

新中国六十年来.伦理学界在伦理学的基本问题等许多问题上都曾经进行过激烈争论,不断开拓伦理学学科体系研究的广度和深度,确立了马克思主义伦理思想体系在当今中国的主导地位,探索了其他理论体系的可能性.     

论条件推理中的两种"高概率结论效应"

用随机抽取的139名大学生和研究生被试,对Oaksford设计的4条条件推理规则的认可度,以及对组成这4条条件推理规则的前后件认可度进行了评定,并根据被试对"条件规则"、组成条件规则的"前件"和"后件"等三个因素上的评定结果各区分为"高"和"低"两个水平.而后对被试在不同评定条件下对每条规则的四种推理结果进行了统计分析.实验结果既支持Oaksford等提出的"推理者对组成条件推理规则的不同的前后件概率组合对推理结论的认可度会有影响"这一观点,也支持邱江等得出的"不同的条件概率对推理者进行推理时对结论认可度的高低会有影响"的论断.前者可称之为"前后件概率的高概率结论效应",后者可称之为"条件概率的高概率结论效应".     

技术的本质与时代的命运——海德格尔《技术的追问》的解读

《技术的追问》是海德格尔1953年11月18日在慕尼黑理工学院所做的演讲。在这篇演讲中,海德格尔从存在之思的角度深思了技术之本质,并取得了3个方面的成果：1．技术本质上并不是各种各样的技术因素,也不仅仅是人所制作的合乎目的的手段。相反,它是一种解蔽方式。2．座架是现代技术的本质特征。座架以及由之产生的进步强制规定并统治着当今的整个社会现实。在座架这个吞噬一切的卡律布迪斯漩涡中,一切存在者都丧失了自身的独立性而沦为单纯的持存物,甚至连人自身也被卷入其中而不能自拔。不是人摆弄座架,而是座架摆弄人。3．座架是形而上学的最后形态,是存在之天命的最后形态。因此,只有凭借思之先导性护送,我们才能在对技术之本质的领会中开启一种新的可能性,即克服作为人类世界栖留的唯一尺度的技术一科学工业之特性。     

Shame as a prospective predictor of self-inflicted injury in borderline personality disorder: A multi-modal analysis

The primary aim of this study was to examine the prospective association of shame with self-inflicted injury (SII), including suicide attempts and nonsuicidal self-injury, among women with borderline personality disorder (BPD) who were enrolled in a clinical trial (N = 77). A multi-method approach was used to assess self-reported shame, nonverbal shame behaviors, and assessor ratings of shame during an interview regarding antecedents for a recent episode of SII. Higher levels of nonverbal shame behaviors predicted a higher likelihood of subsequent SII, and shorter time to SII, after controlling for past SII as well as other emotions associated with SII. Self-reported state shame and assessor ratings of shame were associated with prospective SII, but not after controlling for other emotions. These findings underscore the important role of shame in SII, particularly shame in the presence of contextual prompts for events that surround episodes of SII.     

Cognitive and Interpersonal Predictors of Stress Generation in Children of Affectively Ill Parents

Stress generation is a process in which individuals, through their depressive symptoms, personal characteristics, and/or behaviors, contribute to the occurrence of stressful life events. While this process has been well documented in adults, few studies have examined it in children. The present study examines whether cognitive and interpersonal vulnerability factors to depression contribute to stress generation in children, independent of their current depressive symptoms. Participants included 140 children (ages 6 to 14) and one of their parents. During an initial assessment, children completed self-report measures assessing cognitive and interpersonal vulnerability factors to depression. Children and their parents also completed measures assessing depressive symptoms. One year later, children and their parents participated in a semi-structured interview assessing the occurrence of stressful life events in the past year. Multi-level modeling results provided strong support for the stress generation process in children of affectively ill parents and highlight the importance of considering gender and age moderation effects.

Hostility‐ and gender‐related differences in oscillatory responses to emotional facial expressions

Hostility is associated with biases in the perception of emotional facial expressions, such that ambiguous or neutral expressions tend to be perceived as threatening or angry. In this study, the effects of hostility and gender on the perception of angry, neutral, and happy faces and on the oscillatory dynamics of cortical responses elicited by these presentations were investigated using time–frequency decomposition by means of wavelet transforms. Feelings of hostility predisposed subjects to perceive happy and neutral faces as less friendly. This effect was more pronounced in women. In hostile subjects, presentation of emotional facial expressions also evoked stronger posterior synchronization in the theta and diminished desynchronization in the alpha band. This may signify a prevalence of emotional responding over cognitive processing. These effects were also more pronounced in females. Hostile females, but not hostile males, additionally showed a widespread synchronization in the alpha band. This synchronization is tentatively explained as a manifestation of inhibitory control which is present in aggressive females, but not in aggressive males. Aggr.

Occult white matter damage contributes to intellectual disability in tuberous sclerosis complex

Whether patients with tuberous sclerosis complex (TSC) have brain normal-appearing white matter (NAWM) damage and whether such damage contributes to their intellectual disability were examined in 15 TSC patients and 15 gender- and age-matched healthy controls using diffusion tensor imaging (DTI). Histogram and region of interest (ROI) analyses of the mean diffusivity (MD) and fractional anisotropy (FA) were performed in the NAWM. Correlations between diffusion indices and the full-scale intelligence quotient (FSIQ) and normalized lesion volume were also investigated. Compared with controls, both histogram and ROI analyses showed significant (P < .05) increased MD and decreased FA in the NAWM of TSC patients. In TSC patients, some of the histogram- and ROI-derived diffusion indices of the NAWM were correlated with FSIQ (P < .01), but none of them were correlated with the normalized lesion volume. These findings indicate that TSC patients have occult damage in the NAWM, which might be an important neural basis for intellectual disability in these patients.     

老庄哲学与上博竹书《恒先》

The bamboo slip essay Hengxian 恒先is historically valuable because it serves to further the ontological understanding and comprehension of issues related to the existence of the universe from the perspective of Laozi’s Daoist thought. Hengxian explores important propositions such as how “Qi originated and activated itself” and “they came out of the same source but differed in nature” from several aspects. The idea that “Hengxian is ‘being’ without any definiteness” responds to the issue of the relationship of difference and identity of all things in the world, and thus examines the interdependent relationships between subjects and objects. It proposes that humans can further understand the existence of the universe through cognitive activities and practices such as “analysis and comparison” in which objective realities are checked. The issues discussed in Hengxian are consistent with Laozi’s Dao de jing, the works of Zhuangzi, Huangdi sijing 黄帝四经 (The Four Classics from the Emperor Yellow) and other Daoist works, and deserve significant attention.
