中学生自我控制能力问卷的编制及其调查 总被引:5,自引:0,他引:5
本研究的目的是编制一套“中学生自我控制能力问卷”,并运用问卷调查了上海地区的885名预初至高二的学生,对中学生自我控制能力的特点进行了探索。研究结果表明:(1)中学生自我控制能力问港山情绪自控、行为白控和思维自控三个维度组成;(2)中学生自我控制能力问卷具有较高的信效度;(3)中学生自我控制能力成正态分市;(4)中学生自我控制能力在年级及性别上的差异非常显着;(5)中学生自我控制能力的发展还不稳定,处于波动之中。 相似文献

现代哲学的逻辑起点不是独断的外在实体,而是无需前提设定而直接自明给予的自我意识。自我主体问题成为连接笛卡尔和康德的一个核心问题。笛卡尔哲学的起点是我思故我在,康德哲学的核心是先验主体的知性为自然立法。康德通过对笛卡尔自我实体性的批判而把自我逻辑功能化, 相似文献

弗雷格认为,句子的断定力真正展现了逻辑学所关心的"真"。并且与语词"真"的冗余论一致,他认为日常语言中缺少与断定力相应的符号。然而,弗雷格却似乎在他所发明的概念文字中为断定力指派了一个特殊的符号:判断杠。本文试图论证,尽管弗雷格直至学术生涯的最后阶段仍然坚持将判断杠保留在其逻辑语言系统之中,但概念文字中的这一设计并不符合他关于逻辑与真之关系的模糊洞见。在论证的关键一步中,我们将借助于胡塞尔关于"信念变异"的学说来澄清"判断"与"断定"之间被弗雷格所忽视的区别。在此基础上,我们最后将简要地提示出对弗雷格关于逻辑与真之关系的模糊洞见进行解读的方向。 相似文献

Fibromyalgia is a syndrome characterized by the presence of diffuse and chronic musculoskeletal pain of unknown etiology. Clinical diagnosis and the merely palliative treatments considerably affect the patient's experience and the chronic course of the disease. Therefore, several authors have emphasized the need to explore issues related to self in these patients. The repertory grid technique (RGT), derived from personal construct theory, is a method designed to assess the patient's construction of self and others. A group of women with fibromyalgia (n = 30) and a control group (n = 30) were assessed using RGT. Women with fibromyalgia also completed the Fibromyalgia Impact Questionnaire and a visualanalogue scale for pain, and painful tender points were explored. Results suggest that these women had a higher present self-ideal self discrepancy and a lower perceived adequacy of others, and it was more likely to find implicative dilemmas among them compared to controls. These dilemmas are a type of cognitive conflict in which the symptom is construed as "enmeshed" with positive characteristics of the self. Finally, implications of these results for the psychological treatment of fibromyalgia are suggested to give a more central role to self-identity issues and to the related cognitive conflicts. 相似文献

Neuronal synchronisation at gamma frequencies (30-100 Hz) has been implicated in cognition and memory. Gamma oscillations can be studied in various in vitro models, but their in vivo validity and their relationship with reference memory remains to be proven. By using the natural variation of wild type C57bl/6J mice, we assessed the relationships between reference memory and gamma oscillations recorded in hippocampal area CA3 in vivo and in vitro. Local field potentials (LFPs) were recorded from area CA3 in behaviourally-characterised freely moving mice, after which hippocampal slices were prepared for recordings in vitro of spontaneous gamma oscillations and kainate-induced gamma oscillations in CA3. The gamma-band power of spontaneous oscillations in vitro correlated with that of CA3 LFP oscillations during inactive behavioural states. The gamma-band power of kainate-induced oscillations correlated with the activity-dependent increase in CA3 LFP gamma-band power in vivo. Kainate-induced gamma-band power correlated with Barnes circular platform performance and object location recognition, but not with object novelty recognition. Kainate-induced gamma-band power was larger in mice that recognised the aversive context, but did not correlate with passive avoidance delay. The correlations between behavioural and electrophysiological measures obtained from the same animals show that the gamma-generating capacity of the CA3 network in vitro is a useful index of in vivo gamma strength and supports an important role of CA3 gamma oscillations in spatial reference memory. 相似文献

Perceptual learning refers to the phenomenon that practice or training in perceptual tasks often substantially improves perceptual performance. Often exhibiting stimulus or task specificities, perceptual learning differs from learning in the cognitive or motor domains. Research on perceptual learning reveals important plasticity in adult perceptual systems, and as well as the limitations in the information processing of the human observer. In this article, we review the behavioral results, mechanisms, physiological basis, computational models, and applications of visual perceptual learning. 相似文献
