This article proposed an affective relationships model with its assessment instrument and examined how Chinese and Japanese adolescents and young adults construct mental representations of their close relationships, and the influence of Confucian cultural beliefs on these representations. The participants were 1,565 students aged 14 to 24 years living in China or Japan. The students were asked about their relationships with four figures: mother, father, closest friend, and romantic partner. We found that: (a) adolescents and young adults in both cultures constructed constellations of relationships containing multiple figures, and they articulated reasons for each figure's significance; and (b) there were between-group differences in the relationships with the father and the romantic partner for Chinese versus Japanese adolescents and young adults. These differences were partly explained by the influence of Confucianism on the Chinese participants’ cultural beliefs that retained the patriarchal values.  相似文献

Three-generation households that include parents and grandparents raising children together have become increasingly common in China. This study examined the relations among depressive symptoms, parenting stress, and caregiver–child relationships in the mother–grandmother dyadic context. Participants were mothers and grandmothers from 136 three-generation households. Results from Actor–Partner Interdependence Mediation Modeling indicated that mothers’ depressive symptoms were indirectly related to mother–child conflict/closeness through own parenting stress; grandmothers’ depressive symptoms were indirectly related to grandmother–child conflict through own parenting stress. Mothers’ depressive symptoms were indirectly related to grandmothers’ conflict with children through grandmothers’ parenting stress, and grandmothers’ depressive symptoms were indirectly related to mothers’ conflict/closeness with children through mothers’ parenting stress. The relation between mothers’ parenting stress and mother–child closeness was stronger than the relation between grandmothers’ parenting stress and grandmother–child closeness. Findings highlight the implications of using a family system perspective and the dyadic approach in understanding and improving family functioning in Chinese three-generation households.  相似文献

Older adults spend much time in solitude (without social interaction), putting them at risk of loneliness, especially if aging outside their country of origin (e.g., Chinese immigrants to Canada). Yet, cultural contextual factors that may reduce loneliness in moments of solitude are poorly understood. This study sought to disentangle the roles of culture, immigration, and acculturation in solitude-loneliness associations across two countries. Community-dwelling adults aged 51–85 in Vancouver (N = 58 East Asian, N = 37 European/North American) and in Hong Kong (N = 56 East/Southeast Asian) completed approximately 30 ecological momentary assessments over 10 days on their current affect and social situations. Participants in Vancouver spent more time in solitude, desired solitude more, and felt less lonely overall than those in Hong Kong. Multilevel models revealed that moments of solitude felt lonelier than moments spent in social interaction, but only for individuals less acculturated to their host culture or not concurrently desiring solitude. Associations held regardless of host culture, cultural heritage, or immigration status. Findings suggest that solitude need not feel lonely if it happens by choice and if individuals feel connected with their host culture, for both immigrant older adults and those aging in their birth country.  相似文献

汉字词匹配的偏侧化效应和事件相关脑电位   总被引:5,自引:2,他引:3  
本研究用音同或形似汉字词对为材料检验大脑半球偏侧化问题。反应时的结果表明音同材料是右视野左半球优势,形似材料是左视野右半球优势。ERP的振幅(特别是P_(300))在音同条件下左半球比右半球显著的小,而在形似材料条件下左右半球无大差别。在两种材料的条件下,ERP潜伏期在左右半球之间也没有显出任何差别。实验结果表明左半球与汉字词匹配时的语音编码有关,而ERP(P_(300))似乎可以做它的一个有效指标。  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

关联负变化(CNV)与反应时的关系   总被引:2,自引:0,他引:2  
本实验采用选择性叠加方法,研究了关联负变化(Contingent NegativVariation以下简称CNV)与反应时的关系。证明:最长、最短反应时差异显著时,相对应的CNV面积差异也显著。CNV的这种差异主要表现在CNV面积的后半部分。对形成这种现象的原因作了讨论。  相似文献

不同车速下司机对交通标志的辨认距离实验   总被引:2,自引:0,他引:2  
本实验所得数据表明,不同车速下司机对同一标志的判读距离是不一样的,车速愈高,司机能判读标志的距离就愈短,同步行时相比,在车速提高到100公里/小时时,司机对标志的判读距离可减低35~45%。据我们的补充实验,这种现象的产生可能是由于司机在高速驾车情况下所产生的生理心理负荷造成的。  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
