青老年组不同难度下心算活动的脑功能磁共振成像研究   总被引:7,自引:0,他引:7  
应用功能磁共振成像技术研究不同心算难度下脑区的活动以及年龄的影响。14名志愿者(20~29岁青年和60~69岁老年被试各7名)参加了该实验。实验任务为2个难度水平的连续减法心算,分别为1000—3和1000—17。结果表明:(1)心算加工激活了额叶和顶叶的许多脑区;(2)大脑左半球是心算加工的优势半球,但随着心算难度加大,大脑一侧化程度下降,而年老加剧了这一趋势;(3)青年组进行简单心算(1000—3)时,额中回未见明显激活,而老年组进行简单心算时,该脑区被明显激活。总体上,额叶和顶叶在心算活动中起着重要作用,而任务难度和年龄对心算加工时脑活动的影响以额中回区最为明显。  相似文献

This study aims to identify themes from the treatment of Chinese families with an adolescent or an adult member suffering from anorexia nervosa (AN), through a multiple case study. This study reveals that self-starvation may be regarded as a cultural metaphor. Four major themes emerged at the family level: self-starvation as an expression of love and control, coalition of the AN daughter with the mother, family loyalty, and the powerlessness and helplessness of the mother. The themes identified are narrative accounts of the Hong Kong Chinese families, rather than causal explanations proposed by Western literature. The emerging themes are believed to be constructed and legitimized by traditional Chinese cultural values, with females being subordinated to and dependent on males and the self being subjugated to or sacrificed for the collective. Treatment implications are discussed.  相似文献

知识分享和组织信任能够有效提高绩效,已在企业组织中得到证实,但在学校组织中是否成立及作用路径如何鲜有实证研究探讨。本研究以天津市10所学校的168名教师为研究对象,通过问卷调查探讨教师对直接上级的信任、知识分享及教师工作绩效之间的关系。路径分析结果显示:教师上级信任和知识分享的不同维度对教师工作绩效的影响存在差异;教师知识分享的质量在教师上级信任的依赖维度与工作绩效的关系中起部分中介作用。  相似文献

Zhuzi (Zhu Xi), Zhang Nanxuan and Lü Donglai continued a discussion begun by Hu Wufeng and his disciples on the subject of “knowing the form of benevolence,” and “seeking for a true mind in an absent one.” One result of their discussion was to make people realize that innately good knowledge and ability are not only manifested in loving one’s parents and respecting one’s elders, but also in the simple acts of drinking when thirsty and eating when hungry. This generated the idea of “manifestation range of innately good knowledge and ability.” However, another conclusion of this discussion claimed that if the desire to drink and eat or the king of Qi’s grudging an ox are included in this range, there would be a danger of viewing innately good knowledge and ability merely as inborn human nature or instinct. This discussion reveals an unsteady relationship between innately good knowledge and ability and the feeling of commiseration, which are sometimes united and sometimes separate.  相似文献

Development in any domain is often characterized by increasingly abstract representations. Recent evidence in the domain of shape recognition provides one example; between 18 and 24 months children appear to build increasingly abstract representations of object shape [Smith, L. B. (2003). Learning to recognize objects. Psychological Science, 14, 244-250]. Abstraction is in part simplification because it requires the removal of irrelevant information. At the same time, part of generalization is ignoring irrelevant differences. The resulting prediction is this: simplification may enable generalization. Four experiments asked whether simple training instances could shortcut the process of abstraction and directly promote appropriate generalization. Toddlers were taught novel object categories with either simple or complex training exemplars. We found that children who learned with simple objects were able to generalize according to shape similarity, typically relevant for early object categories, better than those who learned with complex objects. Abstraction is the product of learning; using simplified - already abstracted instances - can short-cut that learning, leading to robust generalization.  相似文献

Social relations in the workplace are one of the main sources of risk for the onset of mobbing. In this work, we analyzed, through the perceived social climate, the influence of interpersonal relations on the characterization of the processes of mobbing, in a sample of local police (N = 235). In particular, the policemen and women's opinions of the quality of the personal relations among the group members and the treatment they receive from the command posts were assessed. The results of the study show that the development of guidelines of social interaction based on discrimination and abuse of authority are predicting variables of mobbing in this group.  相似文献

The main purpose of this article is to examine whether cognitive plasticity increases after cognitive training in Alzheimer's disease patients. Twenty six patients participated in this study, all of them diagnosed with mild Alzheimer's disease, 17 of them received a cognitive training program during 6 months, and the other 9 were assigned to the control group. Participants were assigned to experimental or control conditions for clinical reasons. In order to assess cognitive plasticity, all patients were assessed before and after treatment with three subtests from the "Bateria de Evaluación de Potencial de Aprendizaje en Demencias" [Assessment Battery of Learning Potential in Dementia] (BEPAD). After treatment, Alzheimer's disease patients improved their performance in all the tasks assessing cognitive plasticity: viso-spatial memory, audio-verbal memory and verbal fluency. However, the cognitive plasticity scores of the patients in the control group decreased. In conclusion, this study showed that cognitive stimulation programs can improve cognitive functioning in mildly demented patients, and patients who do not receive any cognitive interventions may reduce their cognitive functioning.  相似文献

Our aim was to study cognitive performance in the early phase of MS. In addition, we studied whether depression, demographic and clinical variables differentiate cognitively impaired patients from non-impaired patients. A group of 52 MS-RR patients with mild level of neurological disability and 51 healthy controls were administered a comprehensive neuropsychological battery. The MS group performed significantly worse on several measures of attention and processing speed and visuoperceptive/visuoconstructive tasks. Verbal memory is characterized by working memory deficits, whereas the visual memory impairment is attributable to deficits in acquisition and consolidation/recuperation. Results shows that cognitive impairment is evident even in MS patients in the early course of their disease. Depression scores were higher in cognitively impaired patients as compared with unimpaired patients. The effect of educational level suggests that higher education delays the onset of cognitive decline.  相似文献
