异同判断加工中整体和局部特征的作用

采用三种整体局部特征（关系-属性,全局-局部,抽象-具体）图形,要求3组大学生被试完成异同判断任务,以考察异同判断加工中整体和局部特征的作用,探讨异同比较的加工机制。三个实验的结果表明：⑴三种整体特征均可加速同反应,因而不支持同判断加工是整体匹配的观点;⑵存在快同效应,但并不支持同判断的快速加工器对整个刺激加工完成后慢速比较器才开始工作的观点;⑶异反应时随差异特征的增多而减小,从而进一步支持异判断是分析加工、自终止的观点;⑷异反应时随差异特征从上至下、从整体到局部而增加,意味着异判断加工的顺序可能是自上而下、从整体到局部。上述结果支持研究假设：同判断的快速加工器先加工整体特征,然后再和异判断的慢速比较器一起开始加工局部特征。     

不同注意条件下的空间－数字反应编码联合效应

考察在无线索、内源性线索与外源性线索时不同符号数字在注意与非注意条件下的空间－数字的反应编码联合效应（Spatial Numerical Association of Response Codes,简称SNARC效应）。采用1到9的中文与阿拉伯数字为材料,以判断数字奇偶为任务。实验结果表明：⑴无线索时注意条件下阿拉伯和中文数字都出现了SNARC效应,而非注意条件下则都没有出现,并且受影响的主要是较大的数字（8、9）;⑵外源性线索和内源性线索时,我们得到一个逐渐递减的SNARC效应,受影响的也主要是较大的数字（8、9）。在内源性线索的注意条件阿拉伯和中文数都有SNARC效应,而在非注意条件只有阿拉伯数有SNARC效应;在外源性线索的注意条件只有阿拉伯数有SNARC效应,而在非注意条件阿拉伯和中文都没有SNARC效应,说明外源性注意的影响比内源性注意更大,中文数字所受的影响比阿拉伯数字更大。     

不同注意条件下大数与小数的加工差异

考察在注意（注视点）与非注意（非注视点）条件下数字加工的距离效应和符号效应。采用小数（1－4）和大数（6－9）的中文与阿拉伯数字为材料,以判断数字是否大于5为任务。实验结果表明：⑴ 在注意条件下,大小数都出现了距离效应;而在非注意条件下,只有小数出现距离效应;⑵ 在注意条件下,大小数都没有出现符号效应;而在非注意条件下,只有小数出现符号效应,中文数字绩效显著好于阿拉伯数字。     

情绪性权衡困难下的决策行为

权衡是决策行为的一个重要特点。情绪性权衡困难是指决策者在对与价值目标相关的特性进行权衡时会产生负性情绪,从而在情感上难以对不同的特性进行权衡。在情绪性权衡困难条件下,认知努力最小化、准确性最大化与负性情绪最小化标准共同影响决策行为,表现出不同于低情绪性决策行为的特点。

Hume on Mental Transparency

This article investigates Hume's account of mental transparency. In this article, I will endorse Qualitative Transparency – that is, the thesis that we cannot fail to apprehend the qualitative characters of our current perceptions, and these apprehensions cannot fail to be veridical – on the basis that, unlike its competitors, it is both weak enough to accommodate the introspective mistakes that Hume recognises, and yet strong enough to make sense of his positive employments of mental transparency. Moreover, Qualitative Transparency is also philosophically satisfying in providing good philosophical reason for why the mental states that are incorrigible should in fact be so.     

自我认知干预对教师心理健康的影响

本研究以自我、个性为内容辅以专家讲座展开了自我认知训练干预,对象为29名随机抽取的中学教师,干预实施持续了两个学期,测查工具为SCL-90、SDS、SAS.结果表明:干预后所有各项的均数均有下降,且除偏执因子外均达P<0.01显著意义水平;干预在偏执因子上效果较为一般,在"躯体化"、"恐怖"、"精神病性"、"饮食睡眠"、"敌对"、诸因子上效果良好,在强迫、人际敏感、焦虑因子上效果更为良好;总之,自我认知干预对教师心理健康具有积极影响,此影响在不同心理因子上会有不同效果.     

Stability of the Positive Mood Effect on Creativity When Task Switching,Practice Effect,and Test Item Differences are Taken into Consideration

Although experimentally induced positive mood can generally last for 20 min and the induced mood is conducive to creative performance, it is still unclear whether the facilitation effect is stable during these 20 min. Two studies were conducted to examine this issue while controlling for the impacts of task switching, practice effect, and test item differences. In Study 1, participants (N = 42) were randomly assigned to positive, negative, and neutral mood conditions. After watching a short video clip, participants answered four items of the Alternate Uses Test (AUT) in 20 min, with 5 min allotted for each item. Creative performance during each 5‐min period was scored in terms of fluency and flexibility. Separate repeated‐measures analyses of variances on these creativity scores showed that positive mood consistently enhanced performance over 20 min. Study 2 further eliminated the effects of test item differences and test order. Participants (N = 131) underwent the same mood induction procedure and answered the same four items of the AUT, except that these items were presented in four different sequences in accordance with the Latin square design. Consistent with the findings in Study 1, Study 2 showed that the facilitation effect of positive mood lasted for 20 min when the interference of task switching, practice effect, and test item differences were minimized. This finding not only sheds light on the debate regarding the stability of experimentally induced positive mood effect, but also contributes to the body of empirical evidence that future studies may use to examine the positive mood effect over a relatively long period of time.
