为探讨脑梗死患者血浆同型半胱氨酸(HCY)水平同病因分型及疾病严重程度的关系,选择首发脑梗死急性期患者73例,对照组30例,进行TOAST病因分型、NIHSS神经功能缺损评分、血浆HCY检测。结果显示,病例组血浆HCY升高率、水平比对照组显著增高;大动脉粥样硬化亚型病例组血浆HCY水平比对照组明显增高;病例组血浆HCY水平同NIHSS评分呈正相关,提示高HCY血症是脑梗死发病及大动脉粥样硬化亚型脑梗死发病的高危因素,血浆HCY水平同神经功能缺损程度正相关。 相似文献

Verbal memory tests—although important to the neuropsychological assessment of memory—are biased to many cultures. In the
present article, we highlighted the limitations associated with the direct translation of tests and word matching, as well
as the lack of ecological validity and cultural appropriateness when tests developed in one culture are used in another. To
overcome these limitations, a verbal memory paradigm was developed that framed the memory assessment with a shopping-list
format, but that developed culturally specific stimuli for the different language groups. The aim of the present study was
to determine the equivalence of this shopping list memory test in different cultural and language groups. Eighty-three adults
from English-, French-, Malay-, and Chinese-speaking cultures participated in four experiments. The results of all the experiments
indicated that performance of verbal list learning is equivalent, irrespective of the language used. These results support
the use of this methodology for minimizing cross-cultural test bias, and have important implications for testing culturally
and linguistically diverse individuals. 相似文献

Change detection performance is influenced by a number of factors, among which is the informativeness of targets. It has not
been clarified, yet, whether the highly informative regions have a processing priority as a result of resource deployment
from other tasks or whether it results from a better resource management. In this paper, we adopted a change detection paradigm
in which thirty participants were randomly assigned to two groups: single (change detection task) and dual task [change detection
and a simplified version of the Paced Auditory Serial Oppository Task (PASOT, Gow and Deary in J Clin Exp Neuropsychol 26:723–736,
2004), which implies a verbal effort]. Stimulus informativeness was defined as social relevance, that is, changing targets were
people (high relevance) versus objects (low relevance), all other aspects (i.e., salience and position in the scene) kept
constant. As hypothesized, data analyses showed a significant main effect of social relevance and task condition, i.e., better
change detection performance and lower change detection times for people versus objects and for single than for dual task
condition. Interestingly, the PASOT accuracy remained stable across the person versus object trials, thus implying that the
better performance with socially relevant targets could not be explained by a resources withdrawal from the secondary task.

为了求证阈下情绪引起的认知偏向是否随增龄而变化及表现如何,选取5,6,7岁儿童、青年人、老年人共183名被试完成阈下情绪启动实验,结果发现:儿童和成年人在阈下呈现哭表情图片条件下,表现出相反的启动效应.成年人表现出情绪一致性效应,而儿童表现出情绪反转效应.笑表情图片在各年龄段被试中均未引起显著的判断偏向.该结果说明儿童处理阈下情绪的隐性心理机制是维持快乐,成人则是预警危险. 相似文献

以1306名小学生为研究对象,对儿童心理一致感量表(CSOC)中文版的心理测量学特征进行分析,并考察小学阶段儿童心理一致感发展的特点.研究结果表明,CSOC中文版量表具有较好的项目鉴别力、内部一致性和稳定性;探索性因素分析和验证性因素分析的结果表明CSOC中文版量表由一致感和不一致感两个因素构成,心理一致感总分与孤独感呈显著负相关;方差分析结果表明,小学儿童心理一致感发展存在显著的性别和年级差异.儿童心理一致感量表中文版具有较好的信效度,可以作为测量中国儿童心理一致感水平的有效工具. 相似文献

The authors investigated how negotiating two cultural expectations may influence the career decision‐making process of Chinese youth. In‐depth interviews were conducted with 8 participants addressing issues of role models, career interests, and individuals with whom they discussed career concerns. Consensual Qualitative Research (C. E. Hill, B. J. Thompson, & E. N. Williams, 1997) was used to analyze data. The findings suggest that parents' academic and career expectations influenced the career decisions of Chinese youth. 相似文献

医护人员对癌症告知态度的调查研究 总被引:6,自引:0,他引:6
为了了解医护人员对癌症告知的态度,对634名医护人员进行问卷调查。结果显示,医护人员不十分赞同将真情完全告知患者,其告知意愿在一定程度上取决于患者的知情愿望,他们比较认同家属拥有决策权,且普遍认为患者不是充分知晓病情。因此,医护人员应该增强告知认识,尊重患者告知意愿,引导家属告知观念,努力提高患者知情程度。 相似文献

中西医学构成了一对不可通约的科学理论,分别代表不同的价值观念和认识方式。基于二者整体的互斥性,且为在实践中取得巨大成功的知识体系,互补是最佳选择。中西医互补的科学内涵为:"结构"医学与"功能"医学互补;"还原"医学与"整体"医学互补;"求简的"医学与"存繁的"医学互补。 相似文献
