为了考察父母、同伴依恋与希望的纵向关系,本研究以大学新生为研究对象,采用父母、同伴依恋问卷与希望量表,对1283名大一学生进行为期一年共三次的追踪研究。结果发现:(1)三次测量的父母、同伴依恋均与希望存在正相关;(2)交叉滞后模型表明,父母、同伴依恋与希望均存在相互影响的关系;(3)基于性别差异的分组模型分析表明,仅同伴依恋与希望的横断关系存在性别差异,女生相关系数显著大于男生。研究揭示,依恋与希望存在稳定的横向相关关系,并且依恋与希望存在相互预测的纵向关系。 相似文献

In the current study, late Chinese–English bilinguals performed a facial expression identification task with emotion words in the task-irrelevant dimension, in either their first language (L1) or second language (L2). The investigation examined the automatic access of the emotional content in words appearing in more than one language. Significant congruency effects were present for both L1 and L2 emotion word processing. Furthermore, the magnitude of emotional face-word Stroop effect in the L1 task was greater as compared to the L2 task, indicating that in L1 participants could access the emotional information in words in a more reliable manner. In summary, these findings provide more support for the automatic access of emotional information in words in the bilinguals’ two languages as well as attenuated emotionality of L2 processing. 相似文献

Local influence analysis is an important statistical method for studying the sensitivity of a proposed model to model inputs.
One of its important issues is related to the appropriate choice of a perturbation vector. In this paper, we develop a general
method to select an appropriate perturbation vector and a second-order local influence measure to address this issue in the
context of latent variable models. An application to nonlinear structural equation models is considered. Six perturbation
schemes are investigated, including three schemes under which simultaneous perturbations are made on components of latent
vectors to assess the influence of these components and pinpoint the influential ones. The proposed procedure is illustrated
by artificial examples and a simulation study as well as a real example. 相似文献

Numerous studies have documented cognitive impairments and hypoactivity in the prefrontal and anterior cingulate cortices in drug users. However, the relationships between opiate dependence and brain structure changes in heroin users are largely unknown. In the present study, we measured the density of gray matter (DGM) with voxel-based morphometry in 30 lifetime heroin-dependent individuals who had abstained from drug use for 5 months, and 34 healthy participants. The DGM of the prefrontal, temporal and cingulate cortices significantly decreased in heroin addicts relative to the healthy group. Critically, partial correlation analysis, which controlled for age, education and gender factors as well as nicotine use and heroin abstinence duration, showed that the duration of heroin use negatively correlated with the DGM in heroin-dependent individuals. These results provide compelling evidence for structural abnormality in heroin-dependent individuals and further suggest that duration of heroin use is a critical factor leading to brain damage. 相似文献

综合以往的释梦理论,结合具体案例,对焦虑梦的运作机制进行了探讨,并提出一种结构化的释梦方法.研究结论:焦虑梦的梦境是由多个相似焦虑事件的记忆元素建构而成,并由梦者睡前所体验的"半成功"地压抑了的焦虑感受所触发.通过对构成梦境的记忆元素进行分析整理,能发现做梦者在做梦前一段时期内比较重要的、重复出现的焦虑主题,从而为心理咨询与治疗提供线索. 相似文献

论当代医学异化与医学人化 总被引:1,自引:0,他引:1
陈飞 《医学与哲学(人文社会医学版)》2009,30(9)
从哲学的深层次看,医学异化的本质是对人性的背离,是一种异己性力量和一种价值危机,它造成医学与人文、医学科学的真与善的分离,导致"人"的失落.医学人化主要是指医学人文化、人性化、人道化,是对医学异化的克服和抛弃.在医学领域,必须从医学异化走向医学人化,从而实现真正的人的医学. 相似文献

Two experiments were conducted to investigate how linguistic information influences attention allocation in visual search and memory for words. In Experiment 1, participants searched for the synonym of a cue word among five words. The distractors included one antonym and three unrelated words. In Experiment 2, participants were asked to judge whether the five words presented on the screen comprise a valid sentence. The relationships among words were sentential, semantically related or unrelated. A memory recognition task followed. Results in both experiments showed that linguistically related words produced better memory performance. We also found that there were significant interactions between linguistic relation conditions and memorization on eye-movement measures, indicating that good memory for words relied on frequent and long fixations during search in the unrelated condition but to a much lesser extent in linguistically related conditions. We conclude that semantic and syntactic associations attenuate the link between overt attention allocation and subsequent memory performance, suggesting that linguistic relatedness can somewhat compensate for a relative lack of attention during word search. 相似文献
