联结竞争对听写困难儿童形音联结编码的影响

听写困难是一种发生率较高的儿童学习障碍现象。听写困难的认知机制,主要包括语音加工缺陷、字形表征缺陷以及形音联结编码缺陷。本研究通过两个实验,考察了整字语音竞争和部件语音竞争,对听写困难儿童形音联结编码的影响。结果发现,在不同条件下,听写困难儿童的形音联结水平都落后于正常儿童;整字语音竞争显著干扰了正常儿童的形音联结编码,但对听写困难儿童的影响并不明显;与之相反的是,部件语音竞争对听写困难儿童的干扰更为明显。研究结果支持听写困难儿童的形音联结编码缺陷理论。在此基础上,听写困难儿童的形音联结较少受到整字语音的竞争干扰,但更容易受到部件语音的竞争干扰,这可能是因为,他(她)们的整体字形加工或表征存在缺陷,导致原生字字形和语音信息难以被激活,以及合体字的部件信息得到更多的加工所致。     

自我欺骗:为了调节个体心理状态

本研究旨在探索自我欺骗的研究方法、产生的原因和认知机制,以及这一领域中有待解决的新问题。近期研究发现:基于自我欺骗产生的动机特点,主要存在三类不同的定义方式,大多数心理学家是基于第三类定义来研究自我欺骗。研究方法上,适用性较强的自欺问卷是自欺性提升量表(SDE),操作性较强的经典实验范式是点追踪任务。在认知过程的任一阶段中,调节心理状态是个体产生自我欺骗的直接动机,改变个体的心理状态或对事物的模糊感知可能阻止个体自我欺骗的产生。未来应从如何调节个体心理状态的角度探讨和研究自我欺骗,能够利用点追踪任务,结合ERPs或fMRI技术为之后研究自欺产生的具体阶段、认知机制以及神经机制提供实证研究基础。     

Age and gender differences in negative affect—Is there a role for emotion regulation?

Elderly people report less negative affect than the young, and women report more negative affect than men. This study investigated whether age and gender differences in negative affect could be explained by emotion regulation, measured as defensiveness and rumination, while controlling for the influence of life events. One-hundred-and-ninety-five young (20–35 years) and 302 elderly (70–85 years) men and women completed the Emotional Control Questionnaire-Rehearsal, Marlowe–Crowne Social Desirability Scale, Profile of Mood States, Beck’s Depression Inventory and List of Recent Experiences. Hierarchical regressions with negative affects as dependent variables showed that age was reduced to non-significance when controlling for defensiveness, and gender was reduced to non-significance when controlling for the interaction between age and gender, which in turn was reduced when entering rumination. Life events also influenced the association between age and negative affect. The results indicate that age differences in negative affect are mediated by defensiveness and life events and that when these two influences are accounted for elderly people score higher on sadness. Gender differences in negative affect were due to the young women’s higher scores on negative affect and this is partly explained by rumination.     

民本思想在近代中国的演变及其特点

民本思想在近代中国经历了三个不同的历史演变阶段：鸦片战争到甲午战争前为民本思想体系开始动摇的阶段;戊戌维新时期为民本思想衰变阶段;辛亥革命时期为民本思想走向衰亡和政治生命终结阶段。其演变的特点有三：其一,民本思想演变始终与近代中国社会主要矛盾的发展变化相联系;其二,民主思想在近代中国的拓展,实际上也是民本思想理论体系逐渐崩溃解体、功能作用日益萎缩的过程;其三,民本思想的演变总是与统治阶级及先进中国人的理想与信念、理论与实践相联系。

不同编码对听写困难儿童字形记忆的促进效应

听写困难是一种发生率较高的儿童学习障碍现象。实验考察笔画语音编码和动作编码对听写困难儿童字形记忆水平的影响。结果发现, 笔画语音编码对听写困难儿童的字形记忆成绩没有明显影响, 但却明显促进了正常儿童的字形记忆成绩; 与之相对, 动作编码对正常儿童的字形记忆成绩没有明显影响, 但却明显促进了听写困难儿童的字形记忆成绩。上述现象, 既可能源于编码加工阶段, 也可能源于字形表征的提取阶段。     

公平与惩罚价格对第三方惩罚需求的影响

为了探讨第三方惩罚的影响因素,分析个体在不同公平情境下面临不同的惩罚成本时会采取怎样的第三方惩罚行为,本研究以171名大学生为被试,采用2×2的混合实验设计,通过设置高低两种不公平情境和3种惩罚价格,对被试的第三方惩罚需求进行实验研究。结果显示,个体的第三方惩罚需求都有随着惩罚价格的升高而降低的趋势;不公平程度显著影响第三方惩罚需求。研究表明,惩罚成本显著影响个体的第三方惩罚的实施;在低不公平情境中,被试面对不同惩罚成本时其第三方惩罚行为之间无显著差异,即各种惩罚成本下出现第三方惩罚行为的可能性均较小;而在高不公平情境中,被试面对不同惩罚成本时的第三方惩罚行为之间差异显著,惩罚成本越低出现第三方惩罚的可能性越大。     

老年患者的外科治疗决策及围手术期处理

泌尿外科老年患者多,老年患者必然手术并发症多,手术死亡率高。虽然现在泌尿外科近70％的手术已进入了微创时代,手术时间大幅缩减,但是老年患者的临床决策仍常常是个非常纠结的问题,手术要达到什么目的？何时要做适当的放弃？除了充分的围手术期准备,医生要敢于承担,家属要充分理解和合作。     

Time course of effects of emotion on item memory and source memory for Chinese words

Although many studies have investigated the effect of emotion on memory, it is unclear whether the effect of emotion extends to all aspects of an event. In addition, it is poorly understood how effects of emotion on item memory and source memory change over time. This study examined the time course of effects of emotion on item memory and source memory. Participants learned intentionally a list of neutral, positive, and negative Chinese words, which were presented twice, and then took test of free recall, followed by recognition and source memory tests, at one of eight delayed points of time. The main findings are (within the time frame of 2 weeks): (1) Negative emotion enhances free recall, whereas there is only a trend that positive emotion enhances free recall. In addition, negative and positive emotions have different points of time at which their effects on free recall reach the greatest magnitude. (2) Negative emotion reduces recognition, whereas positive emotion has no effect on recognition. (3) Neither positive nor negative emotion has any effect on source memory. The above findings indicate that effect of emotion does not necessarily extend to all aspects of an event and that valence is a critical modulating factor in effect of emotion on item memory. Furthermore, emotion does not affect the time course of item memory and source memory, at least with a time frame of 2 weeks. This study has implications for establishing the theoretical model regarding the effect of emotion on memory.
