On the basis of previous theoretical and empirical analyses of the comparative structures of guilt and shame, the authors hypothesized that antecedent condition (personal inadequacy vs. moral norm violation), audience presence, and personal responsibility attribution would distinguish shame from guilt. Although the subject population was Hong Kong Chinese, evidence from previous studies suggests that the comparative structures of guilt and shame are quite similar across cultures. The subjects were asked to recall either a guilt or a shame incident, and their responses were then coded into the predictor variables. The results of the study indicated that guilt was most likely to emerge when individuals had violated a moral norm and held themselves responsible for their conduct. In contrast, shame emerged more frequently when subjects felt personally inadequate than when they had violated moral norms. Moreover, when a guilt incident was reported, and audience was rarely mentioned, whereas subjects who reported a shame incident would generally feel personally responsible and often mentioned being looked at or evaluated. However, neither personal responsibility nor the presence of an audience seemed to be essential for a person to experience shame. 相似文献

语意好恶度在人物观感研究中构成的系统性偏差 总被引:1,自引:0,他引:1
本研究要旨在探讨问卷中题目的语意好恶度在人物观感研究中所构成的系统性偏差效应。被试为87名大学生。他们需要评定如果要在某一项专业上有优良的表现,哪些性格特征会比较重要。我们把被试随机地分成三组,然后指示每一组被试分别就三种性质很不同的专业的其中一种评鉴121项性格特征的重要性。跟着我们采用每一性格特征的重要度评分与它的语意好恶值进行了一连串的相关分析。结果发现性格特征形容词的语意好恶度可能会对被试在人物观感研究中的评分构成系统性偏差的。最后笔者针对这研究结果引申出来的方法问题提出了一些建议。 相似文献

3-6岁幼儿在分类实验中概括能力的发展 总被引:5,自引:0,他引:5
本研究通过设计不同性质的分类实验,探讨3-6岁幼儿抽象概括能力的发展。我们根据年龄将幼儿分为四个组,每组80人,共320人。通过实验获得以下几点。①幼儿在各种不同性质的分类实验中可表现为四级不同的水平,如从根据表面的个别特征进行分类发展到根据内部的本质特征进行分类,从一维角度的分类发展到从两维角度来分类等。⑦达到各个水平的年龄不是截然划分的,而是互相交织的,随着年龄的增加,低级水平的人数不断减少,高级水平的人数不断增加。所以年龄阶段之间既有质的变化,又有量的变化。③对于不同性质的分类材料,各年龄所达到的概括水平也不同,分类材料的难度越大,概括水平越低。④儿童概括水平的高低受教育条件的影响。 相似文献

Alternate monocular and binocular exposure to complementary stimulation can yield opposite but coexisting aftereffects that are contingent on whether the test display is viewed with one eye or two eyes. The motion aftereffect was studied by adapting each eye separately to a contracting spiral and both eyes together to an expanding spiral. The stationary test spiral subsequently appeared to be expanding when viewed monocularly, but to be contracting when it was seen with both eyes open. With respect to the McCollough effect, after monocular exposure to red-vertical and green-horizontal gratings and binocular exposure to red-horizontal and green-vertical gratings, the appearance of the color of the test gratings when viewed with one eye was different from that when viewed with both eyes. Opposite, coexisting aftereffects induced by complementary stimulation can be interpreted as evidence that there are unique binocular aspects to visual function. 相似文献

不同时相日光下颜色的恒常性 总被引:1,自引:0,他引:1
一、前言 在光源光谱成份改变的条件下,我们周围物体的颜色在眼睛看来保持相对不变,称为颜色恒常性。1807年Thomas Young首先描述了颜色恒常性现象,他指出室内不管是由蜡烛的黄光或火焰的红光来照明的,书页纸仍然看来是白色的。Young认为,外界某一表面的颜色外观,并不完全决定于网膜的红、绿、蓝三种感受器的吸收特性,而也依赖于周围其它物体射入眼睛的光通量。此后,E.Hering对颜色恒常性做了实验表演。一般认为颜色恒常性是对环境照明感受性的降低。视觉通道只传递由物体表面所反射的光谱成 相似文献

While much of the previous research has examined the influence of consumers' social and economic states on conspicuous consumption, little attention has been paid to the potential role that consumers' decision-making tendency plays. This study investigates whether, how, and when maximizing, as a type of decision-making tendency (both dispositional and situationally primed), influences subsequent decisions regarding conspicuous consumption. Four studies were conducted, revealing that maximizing consumers are more likely to engage in conspicuous consumption than non-maximizing consumers (Studies 1 and 2). The need for status serves as the underlying mechanism behind this behavior (Study 3). In addition, the observed effect holds only when the situation is public but disappears when it is private (Study 4). As one of the first investigations into the effect that maximizing has on a type of consumption, these findings offer valuable contributions to both theory and practice. 相似文献

Checkerboards contain fundamental two-dimensional Fourier components oriented 45° from the edges of individual checks. Previous studies have shown that contingent color aftereffects following adaptation to chromatic checkerboard stimuli were associated with the fundamental components rather than the edges, In the present experiments, we measured contingent color aftereffects, using the method of constant stimuli, after subjects adapted to unfiltered checkerboards and checkerboards with the fundamental Fourier components removed. The adaptation stimuli were magenta (or green) squares and green (or magenta) diamonds; the test stimuli were vertical or oblique sine-wave gratings with different saturations, After adaptation to unfiltered checkerboards, aftereffects contingent on the fundamental components were obtained. In contrast, after adaptation to filtered stimuli, aftereffects of smaller magnitude were found to be aligned with the edges. The data support the previous findings of spatial-frequency-contingent color after-effects with checkerboard adaptation stimuli and indicate that the aftereffects can be associated with edges if the fundamental components of adaptation stimuli are removed by spatial filtering. We reexamined the possibility of color aftereffects induced by imagery of checkerboards. Contrary to the previous reports, no significant aftereffects were obtained. 相似文献

A total of 142 first grade and 188 fifth grade schoolchildren from Beijing were tested on 11 cognitive tasks. The parents of these children were surveyed with questionnaires to obtain family background materials, and were asked about their expectancies of their children's future careers and future educational achievements. It was found that fifth grade children from high career (professional) expectancy fathers tend to have better developed cognitive abilities, however there is no career expectancy effect on first grade children. Children from high school achievement expectancy fathers tend to have better developed cognitive skills, this educational expectancy effect is stronger for fifth grade children than first grade children. There is a general trend that the higher the educational level of the fathers, the higher expectancy they have for their children. 相似文献
