In Korea, two number systems are in simultaneous use. One is somewhat irregular (like the English language number system), and the other regular (similar to the Chinese number system). This natural experiment allows a direct test of the hypothesis that structural regularity of the number system facilitates the acquisition of counting. Korean children initially suffer from their numerical ‘bilingualism’: they find it difficult to learn two counting systems at the same time. Yet, after this initial difficulty, they soon master the generative rules which are transparent in the regular system. The cognitive advantage provided by the regular number system then combines with other factors, like intensive teaching and parental pressure, to produce school achievement in mathematics superior to US children's. 相似文献

动词语义和句子语法对代词加工的影响 总被引:6,自引:1,他引:5
考察了动词语义和句子语法对代词加工的影响.结果表明,动词语义是影响代词理解的一个因素;相同语法功能假设尚需进一步验证,研究者还提出代词理解受社会文化因素影响的假设。 相似文献

设计三种情境考察被试的推理情况,并试图揭示儿童是怎样进行传递性关系推理的。结果显示:(1)3—6岁儿童具有进行传递性关系推理能力;(2)造成我国3—6岁儿童作传递性关系推理失败的原因有二:一是错误理解比较句式,二是没有记住前提;(3)3—6岁儿童进行传递性关系推理的内部过程不同:小年龄段被试多采用“局部加工模式”,大龄段被试多采用“整体空间加工模式”。 相似文献

情绪活动和某些生理机能或心理过程的关系很久以来就已进行过大量的研究。外科手术前患者的情绪状态及其相应的生理机能的变化,也曾受到注意。患者在意识清醒状态下进行针麻手术,他的情绪状态对针麻过程及其效果的作用如何,这种情绪状态和某些心理、生理机能有什么联系?这是针麻临床上和理论上应予探讨的问题之一。本工作试图综合分析患者的情绪状态和与之伴随的某些生理生化指标变化,以探讨 相似文献

摘 要 随着近年来人工智能深度学习技术的发展,情感计算与人格计算技术日渐成熟,在许多实际应用场景中取得了良好的表现,当前人工智能情感计算技术应用于犯罪风险评估领域,能够有效解决目前主流的风险评估工具难以解决的个体内差异性的预测因子评估问题以及被测评参与者因社会赞许性而导致结果失真的问题。本文在详细阐述目前主流评估工具的局限性基础上,详细阐述了以情感计算技术为支撑的动态风险评估工具的设计思路、目前已有的技术方案以及设计细节的理论依据,在此基础上最后提出以人工智能技术为支撑的新型评估工具的未来发展方向。 相似文献

Humans conduct visual search more efficiently when the same display is presented for a second time, showing learning of repeated spatial contexts. In this study, we investigate spatial context learning in two tasks: visual search and change detection. In both tasks, we ask whether subjects learn to associate the target with the entire spatial layout of a repeated display (configural learning) or with individual distractor locations (nonconfigural learning). We show that nonconfigural learning results from visual search tasks, but not from change detection tasks. Furthermore, a spatial layout acquired in visual search tasks does not enhance change detection on the same display, whereas a spatial layout acquired in change detection tasks moderately enhances visual search. We suggest that although spatial context learning occurs in multiple tasks, the content of learning is, in part, task specific. 相似文献

Fear-related processing in the amygdala has been well documented, but its role in signaling other emotions remains controversial. The authors recovered signal loss in the amygdala at high-field strength using an inward spiral pulse sequence and probed its response to pictures varying in their degree of portrayed sadness. These pictures were presented as intermittent task-irrelevant distractors during a concurrent visual oddball task. Relative to neutral distractors, sad distractors elicited greater activation along ventral brain regions, including the amygdala, fusiform gyrus, and inferior frontal gyrus. In contrast, oddball targets engaged dorsal sectors of frontal, parietal, and cingulate cortices. The amygdala's role in emotional evaluation thus extends to images of grief and despair as well as to those depicting violence and threat. 相似文献

助推爱心:利用默认选项促进捐赠行为 总被引:10,自引:1,他引:9
本研究采用实验室和现场实验的方法检验了默认选项的助推策略是否能够促进慈善捐赠行为。结果发现:(1)相较于把被试费的“保留选项”设置为默认,把“捐献选项”设置为默认时,被试捐献的概率和金额更高;(2)在多个捐款选项情景中,默认选项的设置总体上提高了默认选项被选择的概率;将最大金额选项设置为默认选项有助于提高被试平均捐赠额。这些发现表明,应用默认选项的助推策略能够有效促进人们的捐赠行为。本研究结果对减少募捐成本、提高募捐效率有所启示。 相似文献

Quality of life assessment in Turkish patients with schizophrenia and their relatives 总被引:2,自引:0,他引:2
Alptekin K Akdede BB Akvardar Y Celikgün S Dilşen NS Durak G Türk A Fidaner H 《Psychological reports》2004,95(1):197-206
Quality of life of first-degree relatives living in the same household with patients having schizophrenia has not been sufficiently explored. 30 patients with schizophrenia (16 women, 14 men), diagnosed using DSM-IV criteria, 31 of their relatives (15 women, 16 men), and 34 control subjects (21 women, 13 men) were included in the study. The mean age of the patients, their relatives, and the control subects were 39.8 +/- 10.9, 58.1 +/- 12.5 and 37.3 +/- 17.0, respectively. The World Health Oranization Quality of Life-Brief Form was administered to all subjects. Quality of life was worse for the patient group than for their relatives and control subjects, but relatives of the patients and control subjects were not significantly different on Quality of life. Quality of life was negatively correlated with the severity of psychopathology and extrapyramidal side effects induced by antipsychotic drugs in the patients. 相似文献
