Driver distraction based lane-keeping assistance

Driver assistance systems could be much more effective, if they were adaptive to the driver’s state. Following the idea of a lane-keeping assistance system, which is adaptive to the use of in-vehicle information systems (IVIS), two field experiments were conducted. The first experiment concerned the influence of typical IVIS tasks on lane-keeping. Most IVIS tasks increased the lateral deviations, but in the majority of cases the drivers were still able to stay in their lane.The second experiment concerned two questions: (1) how much lateral support would be needed and (2) how drivers accept this kind of support. The results show that all lateral support algorithms increased the lane-keeping performance with the algorithms providing a higher amount of assistance proving the most useful. All assistance systems were rated as helpful and were considered to increase driver safety, both by the drivers who did not have problems in lane-keeping without assistance.In light of these results an adaptation of a lateral support system to the IVIS-use seems to be useful and worthwhile.     

Mom’s shadow: structure-from-motion in newly hatched chicks as revealed by an imprinting procedure

The ability to recognize three-dimensional objects from two-dimensional (2-D) displays was investigated in domestic chicks, focusing on the role of the object’s motion. In Experiment 1 newly hatched chicks, imprinted on a three-dimensional (3-D) object, were allowed to choose between the shadows of the familiar object and of an object never seen before. In Experiments 2 and 3 random-dot displays were used to produce the perception of a solid shape only when set in motion. Overall, the results showed that domestic chicks were able to recognize familiar shapes from 2-D motion stimuli. It is likely that similar general mechanisms underlying the perception of structure-from-motion and the extraction of 3-D information are shared by humans and animals. The present data shows that they occur similarly in birds as known for mammals, two separate vertebrate classes; this possibly indicates a common phylogenetic origin of these processes.     

Referral Source Differences in Functional Impairment Levels for Children Served in the Comprehensive Community Mental Health Services for Children and Their Families Program

We report one of the first multi-site investigations into referral source variation in functional impairment for children with serious emotional disturbance served in systems of care settings. Baseline data collected as part of the national evaluation for the Comprehensive Community Mental Health Services for Children and Their Families Program was used to assess the comparability of functional status for children referred from traditional mental health versus non-mental health agencies. Results indicate that children referred from child welfare and family groups have significantly lower levels of overall dysfunction than those referred from mental health, while children referred from school and juvenile justice agencies have comparable levels. Clinical and research implications are discussed.     

基于网络理论的物质成瘾新视角

物质成瘾是一种涉及生理、心理和环境等多因素的复杂现象, 但是当前基于生物还原论的解释对物质成瘾现象整体性的理解和康复研究造成了阻碍。网络理论聚焦于心理障碍变量之间相互作用形成的反馈环路, 从整体视角为研究物质成瘾提供了新的理论框架。将网络理论应用于物质成瘾的研究中将有利于:(1)理解症状之间的相互关系和影响; (2)理解症状网络的整体性和系统性动态变化过程; 以及(3)将多层次和多水平因素整合到统一的理论框架中。从网络理论视角来理解物质成瘾, 也将对未来的干预和治疗提供了理论支持。目前, 网络理论仍处于言语模型阶段, 未来需要进一步提出更具体、可验证的统计模型, 以完善对于物质成瘾机制的了解, 更加有效地推进物质成瘾的治疗与恢复。     

自恋与行为抑制/激活系统的关系：元分析

运用元分析方法探讨自恋与行为抑制/激活系统的关系。经过文献检索和筛选, 纳入原始文献19篇, 包含25个独立样本, 共7702名被试。根据同质性检验结果, 选用随机效应模型。结果发现, 自恋与行为抑制系统存在中度负相关(r = -0.27, 95% CI为[-0.34, -0.21]), 自恋测量工具在两者间起显著的调节作用; 自恋与行为激活系统存在高度正相关(r = 0.46, 95% CI为[0.40, 0.52]), 被试类型在两者间起显著的调节作用。自恋与行为抑制/激活系统的密切关系支持了自恋的主体性理论和人格强化敏感性理论。     

非符号数量表征和符号分数表征的关系

个体学习符号分数的一个关键是能对其数值形成准确表征。现有研究假设符号分数表征的认知基础是人类自婴幼儿期就具有的非符号数量表征(如表征两个集合各自的数量, 或两个数量的比例)。其证据包括表征非符号数量(尤其是非符号数量比例关系)和表征符号分数在行为和大脑神经活动层面上都表现出相关性。然而要说明非符号数量表征是符号分数表征的认知基础, 还需更多研究表明两者在数量概念上的独特相关和因果联系, 并阐明符号分数表征形成的认知机制。     

自主选择对大学生情绪调节的作用:来自自主神经反应的证据

为了探究自主选择对积极和消极情绪主观体验及自主神经反应的影响;本研究采用情境选择范式;随机招募41名天津某大学在校生;在自主和强制两种选择下先后观看积极图片和消极图片。结果发现;在积极情境中;自主选择的积极情绪体验显著高于强制选择;高频心率变异性边缘大于强制选择;低频与高频心率变异性比值显著小于强制选择;在消极情境中;自主选择的消极情绪体验边缘低于强制选择;高频心率变异性边缘大于强制选择;低频与高频心率变异性比值显著小于强制选择。研究表明;自主选择增加了被试的积极情绪体验;降低被试的消极情绪体验;同时降低了被试的生理唤醒水平;从而维持最佳情绪状态。     

中国特色社会心理服务体系建设的路径分析

社会心理服务体系作为培育良好社会心态的公共服务体系,有着公共服务体系具有的基本特征：普惠性、公平性和动态性。同时,作为社会治理体系的有机组成部分,这个体系的功能是促进社会治理现代化和科学化,营造和谐的社会心态。中国特色社会心理服务体系建设需要立足我国国情,注重以下方面：党政集中统一领导、针对性的心理服务内容、多元化的心理服务载体、专兼职互补的心理服务队伍、循序渐进的建设重点。     

数学焦虑个体近似数量加工的神经机制:一项EEG研究

近似数量加工是对大数目物体数量在不依赖逐个数数前提下的估计。行为学研究提示高数学焦虑人群近似数量加工能力下降, 但神经机制未明。本研究探讨高数学焦虑个体近似数量加工的神经机制, 比较高低数学焦虑脑电活动的差异:(1)行为上无显著组间差异; (2)高数学焦虑组的P2p成分波幅增加; (3) δ频段ERS及β频段ERD无显著数量比例效应, 而低数学焦虑组在上述指标的数量比例效应显著。本研究为高数学焦虑人群近似数量加工能力下降提供了电生理学的证据。     

欧美生命伦理委员会的机构建设与咨询服务

在当今国际世界,生命伦理学已经发展成一种国际性的“社会运动”,成为学术界和公众关注的热点领域。在欧美国家健全和完善现代医疗保健制度过程中,“生命伦理委员会”起到至关重要的作用,它不仅促使人们从伦理学角度探索“我/我们应当如何决定和行为”的问题,也推动社会从制度建构和文化塑造层面回答“政府应当如何行为”、“如何增进公民的生命伦理意识”等问题,并从哲学领域深入探索如何应对生命伦理学理论与实践中的复杂问题与困境,论证相关伦理选择及其实践的合理性。20世纪60年代以来,欧美社会生命伦理学在机构建设、咨询服务和思维方式等方面的经验可以为中国生命伦理学学科发展及生命伦理委员会建设提供有益的参考。
