为探究幼儿联合行动共同表征能力的发展,实验1通过比较186名3~5岁幼儿在相同任务和不同任务的表现,发现4岁和5岁幼儿在不同任务中的表现比相同任务差;实验2进一步验证幼儿在不同任务中较差的表现源于对自我和同伴的共同表征。结论:3岁幼儿无法在联合任务中同时表征自我和同伴,没有表现出明显的共同表征能力,4岁以上幼儿开始具备稳定的共同表征能力,能够在联合任务中同时表征自己和同伴,由此对自己的行为表现造成干扰。  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

Cross-culturally measurement invariant instruments are useful for the assessment of mental symptoms across cultures. The current study aimed to investigate the psychometric properties and measurement invariance of the Depression, Anxiety and Stress Scales (DASS-21) (DASS) across Pakistan and Germany. German participants were recruited through an online survey (N = 1323), while Pakistani participants were recruited through online survey or paper-and-pencil survey (N = 1841). The DASS-21 showed good reliability, construct and structure validity in both countries. The DASS-21 indicated partial weak (stress subscale) and partial strong measurement invariance (depression and anxiety subscales) between both countries. Latent mean comparison of depression and anxiety symptoms between Pakistani and German students indicated that Pakistani university students experience more symptoms of depression and anxiety. Results suggest that the DASS-21 could be used in Pakistan and Germany, but caution should be taken when making direct comparisons between the two countries.  相似文献

This paper extends investigation of religiosity and longevity to Taiwan using a 1989 survey: N = 3849, aged 60+, with 18 years of follow-up. Religious activity is measured as worship and performance of rituals. A Gompertz regression, adjusted and non-adjusted for covariates and mediating factors, shows the hazard of dying is lower for the religiously active versus the non-active. Transformed into life table functions, a 60-year-old religiously active Taiwanese female lives more than 1 year longer than her non-religious counterpart, ceteris paribus. Mainland Chinese migrants are examined carefully because of unique religious and health characteristics. They live longer, but the religiosity gap is similar.

The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres’ than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources.  相似文献

近期发现,采用目标探测任务作为二级任务时,目标探测条件不仅不会削弱,甚至会提高记忆成绩,产生注意促进效应(ABE)。为进一步探究目标探测的作用机制,研究采用事件相关电位(ERP)技术,对比目标与分心条件在编码和提取过程中所诱发的ERP差异。结果表明,两类条件在再认过程中所诱发的ERP差异不仅表现在早期与知觉加工相关的ERP成份上,并且一直持续到了后期与细节提取相关的ERP成分上。由此推测,ABE不仅体现在编码早期的知觉加工阶段,更会延续到后期的复述与精加工。  相似文献

Several eye-movement studies have revealed flexibility in the parafoveal processing of character-order information in Chinese reading. In particular, studies show that processing a two-character word in a sentence benefits more from parafoveal preview of a nonword created by transposing rather than replacing its two characters. One issue that has not been investigated is whether the contextual predictability of the target word influences this processing of character order information. However, such a finding would provide novel evidence for an early influence of context on lexical processing in Chinese reading. Accordingly, we investigated this issue in an eye-movement experiment using the boundary paradigm and sentences containing two-character target words with high or low contextual predictability. Prior to the reader’s gaze crossing an invisible boundary, each target word was shown normally (i.e. a valid preview) or with its two characters either transposed or replaced by unrelated characters to create invalid nonword previews. These invalid previews reverted to the target word once the reader’s gaze crossed the invisible boundary. The results showed larger preview benefits (i.e. a decrease in fixation times) for target words following transposed-character than substituted-character previews, revealing a transposed-character effect similar to that in previous research. In addition, a word predictability effect (shorter fixation times for words with high than low predictability) was observed following both valid and transposed-character previews, but not substituted-character previews. The findings therefore reveal that context can influence an early stage of lexical processing in Chinese reading during which character order is processed flexibly.

以498名高中生为研究对象,通过问卷调查法探讨高中生的自我妨碍与学习投入的关系,并考察学业浮力的中介作用以及父母支持的调节作用。测量工具包括自我妨碍量表、学习投入量表、学业浮力量表和父母自主支持量表。结果表明:(1)自我妨碍对学习投入有显著负向预测作用;(2)学业浮力在自我妨碍和学习投入的关系中起部分中介作用;(3)自我妨碍和学习投入的关系受到父母支持的调节。与低父母支持相比,在高父母支持的学生中,自我妨碍对学习投入有更强的负向预测作用。  相似文献

This article examines the theoretical basis of decision-making deficits exhibited by cocaine abusers in a laboratory decision-making task first described by Bechara, Damasio, Damasio, and Anderson (1994). A total of 12 male cocaine abusers and 14 comparison subjects performed the task, and the cocaine group performed significantly worse than the comparison group. A cognitive modeling analysis (Busemeyer & Stout, 2002) was used to estimate three parameters that measure importance of the cognitive, motivational, and response processes for determining the observed performance deficit. The results of this analysis indicated, for the first time, that motivational and choice consistency factors, but not learning/ memory were mainly responsible for the decision-making deficit of the cocaine abusers in this task.  相似文献
