红光照明条件下VDT不同显示色的视觉效果比较 总被引:2,自引:1,他引:1
本研究以VDT上持续进行的视觉作业速度和眼的调节辐合时间作为指标,对红光照明条件下VDT显示的红、黄、绿、蓝、白五种字符色的视觉效果进行了比较.实验中,VDT背景光的主波长为630nm.结果表明,五种字符色在两项指标上均表现出显著差异;绿色显示的视觉效果最好,红色显示的效果最差,黄、白、蓝三色处于中间. 相似文献

Smith-Lemli-Opitz (SLO) syndrome is a congenital disorder characterized by severe mental retardation. Patients with SLO lack
7-dehydrocholesterol (7 dH) reductase, which catalyzes the last step of cholesterol synthesis. Administration of an agent
that blocks 7 dH cholesterol reductase, BM 15.966 (BM), leads to a biochemical profile which resembles that of SLO patients,
i.e., lower plasma, live and brain cholesterol levels accompanied by the appearance of the precursors 7 dH and 8 dH cholesterol.
In this article we address the functional consequences of chronic BM treatment on new motor learning by assessing acquisition
of the classically conditioned eyeblink response. Just-weaned rats were fed BM by gavage for four months, with half of these
rats given exogenous cholesterol during the last two months of BM treatment. Acquisition of the eyeblink response was impaired
in BM-treated rats. Impaired acquisition of the eyeblink response was not accompanied by alterations in responsiveness to
either the conditioned or unconditioned stimulus. Exogenous cholesterol, a clinically relevant countertreatment, failed to
correct for the learning impairment produced by BM treatment. Chronic treatment with a cholesterol synthesis-blocking agent
impaired associative learning in just-weaned rats. 相似文献

高压氧对小鼠学习记忆及脑细胞形态结构的影响 总被引:2,自引:0,他引:2
实验用两种行为模型(旷场行为模型和Y-迷宫分辨学习模型)观察了幼龄小鼠在不同压力的高压氧处理后,对新异环境的探究行为和自发活动情况,以及学习记忆能力的变化;并用XY-生物医学电脑图像分析仪分析了与学习记忆相关的脑区(大脑皮层、海马)神经元密度,细胞核面积,胞核/胞浆比值的变化。结果表明:(1)与对照组相比,吸0.1MPa高压氧的幼鼠学习记忆能力明显提高,相关脑区的神经元密度、细胞核面积、胞核/浆比均显著增加。(2)吸0.25MPa高压氧的幼鼠学习记忆能力与对照组相比无明显变化,但其在新异环境中的自发行为明显减少。提示:慢性吸入0.1MPa高压氧有利于促进幼鼠脑的生长发育,增强脑功能活动。 相似文献

为了解中国当事人如何看待咨询中的工作同盟, 对工作同盟做初步的本土概念化, 采用协商一致的质的研究方法对来自1所大学心理咨询中心的20名当事人的访谈结果进行了分析。结果发现, 与工作同盟相关的域有6个, 分别是情感联结、任务、投入、合作模式、发展变化、影响因素。前三个域可以看作是工作同盟的构成要素, 而后三个域则是对其外部特征的描述。对每个域的含义及其与现有理论和研究的关系进行了讨论。 相似文献

118名儿童、少年、青年、中年和老年被试参加"位置法"记忆训练,在训练前后对被试进行了一些认知功能的测查,以探讨被试的年龄及认知能力诸因素对记忆训练效果的影响及其预测性。结果表明:①训练前字词和图形记忆成绩、"数字符号"测验成绩与训练后记忆成绩相关极其显著,"词汇"测验成绩和想象力与训练后记忆成绩的相关也达到显著性水平;②年龄与训练后记忆效果的关系是非线性的;③除"词汇"成绩外,各项认知成绩均可预测训练后字词记忆成绩,训练后的图形记忆迁移效果可由"数字符号"测验成绩预测。 相似文献

Numerous studies have found that shame increases individuals’ anger at others. However, according to recent theories about the social function of shame and anger at others, it is possible that shame controls individuals’ anger at others in specific conditions. We replicated previous findings that shame increased individuals’ anger at others’ unfairness, when others were not aware of the individual’s experience of shameful events. We also found for the first time that shame controlled or even decreased individuals’ anger at others’ unfairness, when others were aware of the individual’s experience of shameful events. The results were consistent when shame was induced by either a recall paradigm or an imagination paradigm, and in either the ultimatum game or the dictator game. This suggests that shame strategically controls individuals’ anger at others to demonstrate that they are willing to benefit others, when facing the risk of social exclusion. Our findings highlight the interpersonal function of shame and deepen the understanding of the relationship between shame and anger at others. 相似文献

Nanoscale Cu-rich precipitates (CRPs) are one of the most important microstructural nano-features responsible for embrittlement and hardening of reactor pressure vessels (RPVs), which threaten the safe operation of nuclear power plants (NPPs) and hinder the lifetime extension of nuclear reactors. A thermally aged Fe-1.1 wt.%Cu alloy, which is used to simulate embrittlement of the irradiated RPV steels, was treated by electropulsing with various parameters. The effect of electropulsing on nanoscale CRPs was investigated by using transmission electron microscopy (TEM). Compared to the traditional heat treatment, the electropulsing treatment (EPT) can accelerate the dissolution of CRPs in an aged Fe-Cu alloy on account of the higher atomic drift flux and the additional Gibbs free energy induced by electropulsing. More importantly, EPT is likely to be a new way of eliminating irradiation-induced Cu-rich precipitates. 相似文献

This study investigated the moderating effects of supervisor–subordinate “guanxi” alongside relevant emotional regulation strategies, including cognitive reappraisal and expressive suppression, undertaken by 402 firefighters experiencing burnout caused by work–family conflict, as revealed through the application and analysis of the job demands–resources model. According to the regression model for the moderating effects, high levels of supervisor–subordinate guanxi may improve the relationship between work–family conflict and burnout, while frequent suppression of expressivity may enhance this relationship. Moreover, when supervisor–subordinate guanxi is high, cognitive reappraisal may effectively mitigate the relationship between work–family conflict and burnout. To this end, both guanxi and cognitive reappraisal are crucial for supporting emotional regulation in the workplaces of ethnic Chinese societies. 相似文献
