Gami-Chunghyuldan ameliorates memory impairment and neurodegeneration induced by intrahippocampal Aβ 1-42 oligomer injection

Soluble oligomeric forms of amyloid beta (AβO) are regarded as a main cause of synaptic and cognitive dysfunction in Alzheimer’s disease (AD) and have been a primary target in the development of drug treatments for AD. The present study utilized a mouse model of AD induced by intrahippocampal injection of AβO (10 μM) to investigate the effects of Gami-Chunghyuldan (GCD), a standardized multi-herbal medicinal formula, on the presentation of memory deficits and neurohistological pathogenesis. GCD (10 and 50 mg/kg/day, 5 days, p.o.) improved AβO-induced memory impairment as well as reduced neuronal cell death, astrogliosis, and microgliosis in the hippocampus. In addition, GCD prevented AβO-triggered synaptic disruption and cholinergic fiber loss. These results suggest that GCD may be useful in the prevention and treatment of AD.     

高中文理分科及学生认知方式对阅读理解影响的实验研究

以高中二年级学生为被试,探讨文理分科、不同认知方式的学生对不同体裁文章及对文章不同信息加工层次的学习效果的影响。结果表明,（1）文理分科、学生认知方式对学生阅读成绩的影响不显著;（2）从总体上看,学生对不同体裁的文章学习效果不同,对说明文的学习明显优于对散文的学习;在文章不同信息的加工层次上,学生对细节的记忆优于对结构的把握;（3）对于不同体裁的文章,学生在信息加工层次上存在差异,对散文的细节记忆好于对结构的把握,对说明文的结构把握好于对细节的记忆。     

平面几何图形内隐学习的优势效应

在人工语法范式下,以平面几何图形为材料。探讨平面几何图形内隐和外显学习的特点,并增设性别变量以了解内隐和外显学习的性别差异。以108名在校大学生为被试,分内隐和外显学习组,每组男女各半。结果表明：1、指导语上不存在主效应,即平面几何图形内隐学习存在优势效应。2、性别变量不存在主效应,即男女在学习能力上性别差异不显著。3、单元变量上存在主效应,单元二的成绩好于单元一。实验结果再次证明了内隐学习优势效应的普遍存在。

The role of social identity in the explanation of collective action: An intergroup perspective on the Yellow Vests movement

Social psychologists have developed influential theoretical models to understand intergroup conflicts, radicalism, and collective action. November 2018 saw the emergence of a new powerful movement in France named the Yellow Vests. Born on social media, the movement has sustained an unprecedented period of intense protests and violent clashes with the police, challenging the French government. As such, this movement offers an ideal context to examine the real-world relevance of current social-psychological theorizing. Using a social identity and self-categorization perspective, two correlational studies (three samples, N = 1,849) tested the role of self-categorization as a group member, or social identity, in accounting for individual participation in normative and nonnormative collective action. Using different operationalizations of identification, both studies confirm a powerful role of identification as a Yellow Vest and provided evidence that the effect of social media use on collective action is fully mediated by self-categorization as a Yellow Vest. An alternative model suggesting that social media use mediated the relation between social identity and collective action was not supported by the data.

幼儿掌握数概念的个案研究——Ⅰ.对一个三周岁至四周岁儿童进行追踪研究的报告

本文是用纵向法,对一个儿童(三周岁至四周岁)掌握数概念的过程,进行追踪研究提出的报告。 研究结果表明:三周岁至四周岁儿童有可能、有必要掌握最初的数概念。数概念广度的发展,是有一定程序的;数概念水平的深化,是通过对计数、取物、比较、运算和读写诸环节的训练而实现的,是从计数活动开始的。掌握数概念,不是自发的、生理成熟的表现,是后天训练、学习的结果。认读数字表,在突破难点时,起相当大的作用。掌握数概念就是掌握有关数的知识,是认识过程,其中动作和记忆具有特别突出的地位。     

潘菽心理学思想的后经验主义蕴含

今年是中国心理学泰斗,理论心理学奠基人潘菽先生诞辰110周年。纪念潘菽先生,意味着继承和发扬潘菽先生的心理学思想。从后经验主义理论心理学的视角来看,潘菽先生的心理学思想仍然具有当代性和启发性,特别是在强调理论对经验研究的优先地位、强调理论对经验现实的建构作用、强调理论的实践品性、强调理论的历史性向度,以及强调理论研究的中国心理学归宿等方面,显示出卓越的远见。
