几何图形类比推理的ERP研究

该研究以几何图形作为实验材料,测定14名硕士研究生在完成两种类比推理任务（大小变化和颜色变化）和其基线任务时的事件相关电位（ERP）,探讨类比推理过程的脑内时程动态变化。研究发现,两种推理任务所诱发的波形基本一致,而推理任务与其基线任务之间的ERP波形存在显著差异,两种基线任务之间的ERP波形也存在显著差异;类比推理的加工过程是有阶段性的,即编码潍断、映射、得出结论,研究结果进一步支持了Sternberg的成分理论;推断和映射这两个类比推理所特有的加工阶段都有其对应的脑机制,图式推断阶段主要激活的是前额皮层和双侧的顶叶皮层,类比映射和调整阶段主要激活的是左半球的颞叶、额叶和中央顶。     

不同视觉区域OUP效应的眼动研究

摘 要 采用眼动方法,通过两个实验考察了不同视觉区域的OUP效应。结果显示：（1）当刺激材料分别平行呈现于左侧视觉区域和右侧视觉区域时,在右侧视觉区域产生了OUP效应,而在左侧视觉区域没有OUP效应,我们假设是由于左侧视觉区域首字母距离中央凹的不利位置影响了OUP效应的产生。（2）当垂直方向呈现刺激时,在两侧视觉区域均产生了明显的OUP效应,表明首字母距离中央凹处于有利位置时不会影响OUP效应的产生。实验结果支持了大脑左半球和右半球在词汇识别时的策略为系列加工,对左半球平行加工右半球系列加工的结论提出了质疑。     

Neural correlates of feigned memory impairment are distinguishable from answering randomly and answering incorrectly: an fMRI and behavioral study

Previous functional magnetic resonance imaging (fMRI) studies have identified activation in the prefrontal-parietal-sub-cortical circuit during feigned memory impairment when comparing with truthful telling. Here, we used fMRI to determine whether neural activity can differentiate between answering correctly, answering randomly, answering incorrectly, and feigned memory impairment. In this study, 12 healthy subjects underwent block-design fMRI while they performed digit task of forced-choice format under four conditions: answering correctly, answering randomly, answering incorrectly, and simulated feigned memory impairment. There were three main results. First, six areas, including the left prefrontal cortex, the left superior temporal lobe, the right postcentral gyrus, the right superior parietal cortex, the right superior occipital cortex, and the right putamen, were significantly modulated by condition type. Second, for some areas, including the right superior parietal cortex, the right postcentral gyrus, the right superior occipital cortex, and the right putamen, brain activity was significantly greater in feigned memory impairment than answering randomly. Third, for the areas including the left prefrontal cortex and the right putamen, brain activity was significantly greater in feigned memory impairment than answering incorrectly. In contrast, for the left superior temporal lobe, brain activity was significantly greater in answering incorrectly than feigned memory impairment. The results suggest that neural correlates of feigned memory impairment are distinguishable from answering randomly and answering incorrectly in healthy subjects.     

Is subordinate's loyalty a precondition of supervisor's benevolent leadership? The moderating effects of supervisor's altruistic personality and perceived organizational support

Based on Cheng's differential leadership theory, we investigated the relationship between a subordinate's loyalty to a supervisor (SLS) and the supervisor's benevolent leadership in Chinese organizations. We also explored two moderators of this relationship, the supervisor's altruistic personality and perceived organizational support (POS). Using survey research, we collected data from supervisor‐subordinate dyads in Taiwan and made 167 valid observations. The results showed that SLS positively relates to the supervisor's benevolent behaviours; however, this relationship is diminished by the supervisor's altruistic personality and POS. That is, when the supervisor has a high level of altruistic personality or POS, the association of SLS with the supervisor's benevolent leadership is weaker.     

哲学的反思与超验

哲学作为“思想的思想”之认识论定位,表明它具有强烈的反思性,亦构成了它的超验性。哲学反思与超验思想的特质,由哲学之认识对象及其与对象的本质关系所规定,亦由哲学之穷是究理的至上性思维使命与中介性递进过程所规定。它们是哲学之谓的重要思想理据。     

试谈道教文化与构建社会主义和谐社会

《道德经》云:“人法地,地法天,天法道,道法自然”,《清静经》说:“大道无形,生育天地;大道无情,运行日月;大道无名,长养万物”,这种体现“道性”的自然、无形、无情、无名,以及“生而不有,为而不恃”、“长而不宰”、“利而不害”的无为精神,谓之“无为之德”。大力弘扬无为之

网络游戏成瘾者的内隐攻击性研究

本研究通过IAT对网络游戏成瘾者的内隐攻击性进行了研究。研究表明:(1)与非网络游戏成瘾者相比,网络游戏成瘾者持有自我攻击性信念和对攻击性的更为积极的内隐态度;(2)网络游戏成瘾者与非网络游戏成瘾者在外显攻击性上没有表现出显著差异。     

幼儿好奇心结构教师评价模型验证性因子分析

在参考已有文献和进行开放式问卷调查的基础上,编制幼儿好奇心教师评定问卷,并以此问卷调查了929名幼儿,运用探索性因子分析和验证性因子分析方法探讨幼儿好奇心结构教师评价模型,结果表明,教师评价幼儿好奇心时存在一个由好问、喜欢摆弄、敏感、关注未知、探索持久、好奇体验以及反应性和探究的主动性等因子构成的三阶结构。     

汉语语音的语义作用研究

本研究采用语音中介语义启动的实验任务,考察了语音表征在语义激活中的作用。实验一发现,在频率较高的词的加工中没有发现语音中介语义启动效应;在频率较低的词的加工中得到了语音中介语义启动效应,但是这种中介启动效应与直接的语义启动效应有显著差异。实验二进一步考察了当声旁读音与整字语音一致时,整字语音在语义通达中的作用,结果发现:不论是高频字还是低频字,语音中介启动对目标词的加工都有促进效应,并且高频条件下,语音中介启动效应与直接的语义启动效应没有显著差异。
