A multisource exploration of the friendship patterns of children with and without learning disabilities

Friendship patterns of 117 children with learning disabilities (LD) and 115 children without LD in Grades 4–8 were examined. In comparison with children without LD, boys with LD had fewer mutual friends, children with LD had more friends with learning problems and more younger friends, and children with LD in Grades 4–6 had less stable relationships. With regard to friendship quality, children with LD reported higher levels of conflict, lower levels of validation, and more problems with relationship repair than did children without LD. The findings were discussed in terms of factors that have been found to enhance friendship such as proximity and similarity, and the social skills difficulties that have been associated with learning disabilities.     

Cognitive and Communicative Abilities of Grey Parrots

Grey parrots ( Psittacus erithacus ) solve various cognitive tasks and acquire and use English speech in ways that often resemble those of very young children. Given that the psittacine brain is organized very differently from that of mammals, these results have intriguing implications for the study and evolution of vocal learning, communication, and cognition.     

Effects of Conflict Resolution Training Integrated Into a High School Social Studies Curriculum

Abstract

The authors examined the effectiveness of conflict resolution and peer mediation training among California high school students. The authors randomly assigned 2 of 4 classes to receive 5 weeks of conflict resolution and peer mediation training integrated into the required social studies curriculum. The remaining 2 classes studied the same social studies curriculum for an identical amount of time (105 min every other day) without conflict resolution and peer mediation training. The authors investigated 2 issues. The 1st was the effectiveness of the conflict resolution and peer mediation training. The trained students, compared with the untrained students, learned the integrative negotiation and peer mediation procedures better, applied the procedures more completely, chose an integrative over a distributive approach to negotiation, and developed more positive attitudes toward conflict. The 2nd issue was the impact of the training program on academic achievement. Integrating conflict resolution and peer mediation training into an academic course promoted higher achievement, greater long-term retention of the academic learning, and greater transfer of academic learning in social studies to language arts.     

孔子是怎样解释《周易》的

孔子与《易》是有密切关系的,抛开《史记》和帛书的记载不言,仅就《论语》中两条最直接的材料来看确实如此。"加我数年……"当为孔子五十之前所说。五十之前,孔子也曾学《易》,而孔子认为知天命之年尤需学《易》。"不占而已"表明孔子解《易》以德,判定吉凶不需要占筮,而是取决于人的德性。孔子以"生生之德性"解《易》,以"道德必然性"解"天命",通过揭去《周易》的神秘外衣,发掘并发展其天人之学,将隐微难言的性与天道托诸于显著的人道德性,发展出天人合一的德性学说。     

Who knows what's good to eat? Infants fail to match the food preferences of antisocial others

Humans gather most of their knowledge about the world, including objectively true facts and specific cultural norms, by observing and being taught by others. Some individuals are worthy teachers and objects of imitation, having knowledge of cultural practices and positive intentions to inform. Others are better ignored because they are ignorant, because they mean us harm, or simply because we do not wish to be “like them.” This study examines whether 16-month-olds are sensitive to the pro- or antisocial behavior of a source that demonstrates preference for two novel foods. Infants took the emotional reactions displayed by novel and previously prosocial sources, but not antisocial sources, into account when deciding what to eat. These results suggest that others’ social behavior influences infants’ likelihood to match their preferences, illustrating the influence of social evaluation on social learning.     

汉语句子理解中句法启动机制的眼动和ERP研究

语言产生的句法启动效应在近20年得到较深入研究。那么, 语言理解和语言产生中, 句法启动效应具有相同的加工机制吗？近些年, 研究者考察了印欧语系语言理解中的启动效应, 但还存在较多争论。这究竟是句法效应, 还是策略或者语义效应, 是词汇驱动还是词汇独立的？而且, 这是人类语言理解的语系特性还是普遍特性？单独采用行为技术、眼动技术或者ERP技术很难为这些争论提供坚实的实验证据和较深入的理论解释。鉴于此, 本项目拟采用眼动和ERP结合的技术, 从心理学、语言学和认知神经科学等多学科交叉的视角考查汉语句子理解的句法启动效应。通过分析眼动和ERP实验提供的一致性和差异性证据, 本项目力图阐明和揭示汉语句子理解中句法启动效应的认知特点和机制, 检验内隐学习理论和论元结构理论在解释句法启动效应时的适用性。     

医疗人工智能科技异化及其伦理风险探析

医疗人工智能广泛应用于现代医疗形式。医疗科技的日新月异,大大推动了人类医学的发展进程及诊疗模式。与此同时,医疗人工智能科技的发展出现了异化现象,并由此带来了人和社会的异化,诸如对人与类人机器的角色定位不清,人对技术的依赖性过度增强,医疗全生命周期中的责任伦理缺失,技术价值失衡等社会问题。以这些异化带来的伦理风险为进度,探析在医疗人工智能使用中的隐私安全与数据使用的边界问题,人在医疗过程中的主体地位问题,“医生-人工智能-患者”的共同决策体系构建问题,构建医疗人工智能科技向善理念及法律问题。     

内隐学习和外显学习关系评述

文章从内隐学习与外显学习的区别、联系以及相互作用三方面,对这两个概念集合间的关系进行了辨析。最初,内隐学习这一概念的提出,是源于其与外显学习在现象学、实验操作、神经生理学以及学习机制等方面的诸多不同。近年来,虽然内隐学习的独立地位已被充分确立,但是,也有越来越多的证据表明,内隐学习和外显学习之间的独立性是相对的,它们之间存在紧密的联系和相互作用,任何一个学习任务都是内隐和外显学习的结合物。最后,作者结合自己的实验研究进一步提出了,内隐学习和外显学习之间相互权衡的动态关系。     

人工体内授精中亲子关系的认定

随着人工体内授精的技术发展与社会思维方式的变化,不仅颠覆了传统亲子关系的认定规则,同时也挑战了以亲子关系为基石的家庭法制。基于人工体内授精技术可能造成血统事实与法律事实的割裂矛盾,应当坚持保密认定、知情同意、风险自负、子女利益最大化等重要原则。同时,以类型化分析为基础,具体化阐释同质人工授精与异质人工授精在适用规则与利益衡量中的不同之处,以最大程度调适人工体内授精中所涉利害关系人的价值冲突。
