听障人群的工作记忆机制

听障人群听觉通道受损,使用手语交流,提供了独特的切入点来探讨工作记忆的结构和功能。研究表明,听障人群具备在功能上与正常人的语音环路平行的手语复述机制。通过发声训练,听障人群也可采用语音编码,即语音环路可被通达。听障人群具有与正常人相当的语言工作记忆资源,但是这种资源在具体使用时受视觉通道处理特性的限制。越来越多的研究支持互补理论,认为手语的使用增强了听障人群非语言的视空间处理能力。     

“解释法”样例对小学生学习新运算规则的促进

为证实“解释法”样例设计的促进作用,实验考察了4年级小学生学习“解释”样例与普通样例、“解释”样例和“解释-标记”与普通样例的迁移效果。结果表明：（1）用“解释”样例学习分数加减运算规则的近迁移成绩明显优于普通样例,但远迁移成绩无显著差异;（2）用“解释-标记”样例学习分数乘除法运算规则的远迁移成绩明显优于“解释”样例和普通样例,但近迁移成绩差异不显著,学习“解释”样例的远迁移效果均明显优于普通样例;（3）学习“解释法”设计的比例运算样例,其远、近迁移成绩均明显优于普通样例的迁移成绩,并受被试先备知识的影响。     

易学图型与佛学圆相在中国哲学发展中的逻辑演进及其意义之管窥

唐、宋时期,将范畴及学说进行图型表达的哲学发展过程中,儒释道也有近似的发展趋向,其中,以圆相为基础图型的佛学阐释和易学图型太极图及其学说,便是哲学图型发展中的典型案例。虽然,佛学圆相大致是由本体论层面的图型诠释而落实到具体修行次第及勘验方式,易学太极图及其学说则由尽可能完善图型诠释而至充实宇宙本体论,但儒释道不同形式的图型演绎,却有异曲同工之妙,更在提高传统哲学思辨水平及丰富思想资源上各有贡献。本文尝试通过述说太极图所出渊源之历史疑问,由此引出相关图型演进问题,进而述说佛学圆相法的运用,以两相陈述相关学说具体发展脉络的方式,尝试对传统哲学图型法的逻辑演进做个初步展示,并联系康德哲学图型法阐释,略窥所涉图型演进问题的意义。     

积极情绪与身心健康关系研究的进展

积极情绪与身体健康、心理健康和社会适应有密切的关系。首先,积极情绪不仅能够降低传染性疾病的感染风险,能够影响非传染性疾病病情、病程及死亡率。其次,积极情绪能够降低个体的心理易感性,使个体更好的应对负性或压力事件。最后,现有的研究表明积极情绪和社会交往存在相互促进的关系。现存的直接效应模型和压力缓冲模型解释了积极情绪直接和间接促进健康的机制。未来的研究还需在研究方法和模型完善等方面进一步改进。     

Augmented Weighted Estimators Dealing with Practical Positivity Violation to Causal inferences in a Random Coefficient Model

Psychometrika - The inverse probability of treatment weighted (IPTW) estimator can be used to make causal inferences under two assumptions: (1) no unobserved confounders (ignorability) and (2)...     

中国背景下自我效能感与心理健康的元分析

社会认知理论指出自我效能感对心理健康具有重要意义,但两者的关系在以往的研究中尚不一致。当前研究采用元分析技术分析自我效能感对心理健康影响的主效应,并重点考察各调节变量在两者关系中的调节效应。通过文献检索和筛查,最终符合元分析纳入标准的文献有117篇。结果表明,自我效能感与心理健康积极因素呈显著正相关,而与心理健康消极因素呈显著负相关。此外自我效能感与心理健康的关系受自我效能感层级、社会发展和性别的调节;而年龄阶段仅调节了自我效能感与心理健康积极因素的关系。以上结果说明,高自我效能感个体的心理健康水平更高,同时还要考虑年龄阶段、自我效能感层级、社会发展和性别在两者关系中的作用。     

Narrative Skills,Gender, Culture,and Children’s Long-Term Memory Accuracy of a Staged Event

This study examined the extent to which school-aged children’s general narrative skills provide cognitive benefits for accurate remembering or enable good storytelling that undermines memory accuracy. European American and Chinese American 6-year-old boys and girls (N = 114) experienced a staged event in the laboratory and were asked to tell a story from a picture book that accessed their narrative skill. Children were interviewed about the staged event 6 months later to assess memory accuracy. Greater narrative skill when storytelling was associated with decreased free recall and recognition memory accuracy for the staged event. In free recall responses, this effect was driven by an increase in the likelihood that inaccurate details would be included in responses from children with better general narrative skills. For girls only, narrative skill predicted poorer recognition accuracy. Girls were also more language-proficient and provided more correct details in free recall than did boys. Chinese American children were more accurate than European American children when responding to recall prompts due to less frequent provision of incorrect details, particularly in girls. Findings are discussed in light of the roles of socialization in memory-reporting accuracy.     

社会支持视角下顾客在线互助心理和行为机制

消费结构升级促使顾客通过参与价值共创获得更高层次心理满足感。顾客间通过网络平台参与交流、互动、分享和互助等价值共创行为,能够获得美好的情感体验,有助于形成人际之间的友谊,也使得顾客得以寻求自我表达和自我实现,收获更高层次的满足感。本研究以社会支持理论为基础,聚焦不同属性顾客在不同类型网站中参与在线互助的心理动机、心理收益和行为方式,采用行为实验、实证调查、案例研究、神经营销学等多种研究方法,深入剖析顾客参与在线互助过程中的心理和行为反应机制。预期研究成果将丰富现有顾客参与心理和行为的理论体系,也为企业激励顾客参与在线价值共创提供理论指导。     

An artificial intelligent counter

This article, using a counter as an example, explores a novel approach in constructing a cognitive system. The system is a paired memory system of “left and right brain” consisting of a number of memory units. The “left brain” is dedicated to the cognitive process of symbols, and the “right brain” to the representation of the symbols. The left and right subsystems are connected by bundles of internal communication signals. The paired memory system can learn facts and generalize concepts. Its cognitive capability is realized through the communication among these memory units at different cognitive levels within the system. The key claims in this paper are supported by empirical findings and theoretical principles. An AI counter is built and demonstrated in terms of concept learning and responding.
