5-11岁儿童元知觉发展的实验研究

本项研究旨在探索 5 -1 1岁儿童元认知发展的规律 ,2 80名昆明市及路南县汉、撒尼族儿童参与了三项知觉实验 ,实验结果表明 :1儿童随年龄的增长 ,有关知觉组织策略的知识及自我监察的能力也逐渐发展 ,表现为系统观察、选取有效策略及计划性的增强。 2儿童对信息的加工不断深入 ,从表浅的加工过渡到详尽的加工 ,不仅要求补充必要的信息 ,而且主动搜索隐蔽的线索以促进识辨。3儿童自我评价从笼统、含糊逐渐向客观、全面发展。4路南儿童元知觉的发展晚于昆明儿童两年 ,但在路南的汉族儿童和撒尼族儿童之间不存在显著差异 ,说明文化教育对儿童元知觉发展的重要影响。     

中国实验心理学三十年

一 实验心理学已有悠久的历史,它建立于前一世纪的中叶,采用自然科学的方法研究心理学问题,在使心理学成为一门独立的科学上起了重要作用。但心理学被介绍到中国来还是在清朝末期,最早的一个心理学实验室是在1917年北京大学哲学系建立的。解放前的旧中国已有七、八个高等学校设置了心理学系,除了讲授普通心理学课程外,还开设     

演绎推理的形式和内容启动加工

聚焦推理加工初期,研究通过指导语操控主观加工倾向,考察不同指导语条件下内容可信度和形式有效性对演绎推理结果的影响,检验内容和形式两类加工过程的启动加工动态变化性。结果表明,指导语条件显著影响推理初期加工。在无提示指导语和形式判定指导语条件下,推理结果受到了形式有效性和内容可信度的影响;内容判定指导语下只受到了内容可信度的影响。证明主观加工倾向影响了内容和形式的启动加工关系,支持了动态变化性的假设。     

儿童对抽象画情绪寓意理解的发展及文化因素的影响

本实验旨在探索儿童对抽象图画情绪寓意敏感性的发展规律以及文化因素的影响。被试年龄跨度从 5岁至高中学生。根据被试利用形态、主题、情绪等图片特性作为识辨依据的特点来发现规律。儿童对抽象图画寓意敏感性的发展与表征水平相关。年幼儿童只能利用颜色或图形等单一信息维量进行判断 ,年长儿童及中学生可以综合利用形态、主题、情绪等多个维量判断。在寓意明确的图片识辨中 ,儿童对积极寓意的识辨成绩较优。在双关寓意的图片识辨中 ,儿童组倾向于选择具有积极寓意的线索 ,而中学生组会受到识辨经验的影响。文化与教育方式影响儿童对抽象图画情绪寓意的理解。中国幼教方式有助于儿童对图画认知与情绪成分的识辨。

自我损耗、情绪动机对冲动决策的影响

以大学生为被试,探讨自我损耗、情绪动机对冲动决策的影响。采用2×2×2的混合实验设计,组内变量为自我损耗,组间变量为情绪动机方向和强度,使用双任务范式操作自我损耗,使用情绪动机图片启动被试的情绪动机,使用延迟折扣任务的指标k值测量冲动决策。结果发现,高趋近动机的k值大于低趋近动机,高回避动机的k值大于低回避动机。结果表明,自我损耗、情绪动机对冲动决策有明显影响。     

Mapping the development of facial expression recognition

Reading the non‐verbal cues from faces to infer the emotional states of others is central to our daily social interactions from very early in life. Despite the relatively well‐documented ontogeny of facial expression recognition in infancy, our understanding of the development of this critical social skill throughout childhood into adulthood remains limited. To this end, using a psychophysical approach we implemented the QUEST threshold‐seeking algorithm to parametrically manipulate the quantity of signals available in faces normalized for contrast and luminance displaying the six emotional expressions, plus neutral. We thus determined observers' perceptual thresholds for effective discrimination of each emotional expression from 5 years of age up to adulthood. Consistent with previous studies, happiness was most easily recognized with minimum signals (35% on average), whereas fear required the maximum signals (97% on average) across groups. Overall, recognition improved with age for all expressions except happiness and fear, for which all age groups including the youngest remained within the adult range. Uniquely, our findings characterize the recognition trajectories of the six basic emotions into three distinct groupings: expressions that show a steep improvement with age – disgust, neutral, and anger; expressions that show a more gradual improvement with age – sadness, surprise; and those that remain stable from early childhood – happiness and fear, indicating that the coding for these expressions is already mature by 5 years of age. Altogether, our data provide for the first time a fine‐grained mapping of the development of facial expression recognition. This approach significantly increases our understanding of the decoding of emotions across development and offers a novel tool to measure impairments for specific facial expressions in developmental clinical populations.     

利用脑成像多体素模式分析解码认知的神经表征:原理和应用

多体素模式分析(multi-voxel pattern analysis,MVPA)是一种基于机器学习理论发展出来的新的功能磁共振数据分析技术。MVPA技术通过训练分类器,对由不同认知状态引起的多体素信号模式进行分类。与传统的基于单个体素的分析方法相比,该技术可更敏感地检测脑对认知状态的表征,并使得从神经信号解码认知状态成为可能。文章介绍MVPA技术的基本原理、分析步骤以及可以用MVPA来解决的科学问题,并对应用中可能面临的问题提供了参考建议。     

Globalization and the contemporary development of Marxist philosophy: precondition, problem domain and research outline

Globalization was just emerging but did not really take shape during Karl Marx’s time. In fact, both Karl Marx and Engels predicted the trend of globalization but did not really live in such a time. Therefore, globalization is still a new issue and a new research area for Marxist philosophy today. Based on the distinctions between some important concepts such as globalization and modernization, this paper probes the problems concerning the development of modernity theory, social morphology and civilization theory, and the Marxist theory of values raised in the process of globalization. The paper also explores some theoretical issues concerning the socialist modernization with Chinese characteristics in the Marxist philosophy, and contemplates possible research areas, angles and methods of Marxist philosophical research in the global era. __________ Translated from Zhexue Yanjiu 哲学研究 (Philosophical Studies), 2005 (9) by Ouyang Kang, Liu Yumei, Zhu Lingling
