新民主主义理论是中共理论创新的典范之一,而这一理论的创立,跟当时国共双方的理论斗争息息相关.本文以第二次国共合作期间中共对三民主义解释策略的演变为线索,回顾了国共双方这一时期的理论斗争历程.在这一理论斗争中,人们常常只关注毛泽东创立了新民主主义理论,而忽略了毛泽东提出的新三民主义理论--联俄、联共、扶助农工三大政策的三民主义.本文在历史考察的基础上提出,毛泽东的新三民主义理论为其新民主主义理论提供了重要的政治基础. 相似文献

功能性近红外光谱技术(functional near-infrared spectroscopy, fNIRS)利用血液的主要成分对600-900nm近红外光良好的散射性,从而获得大脑活动时氧合血红蛋白和脱氧血红蛋白的变化情况。目前该技术开始运用于自然情境下的高级认知、发展心理学、异常心理学等多个领域的研究。该技术具有造价较低、便携性好,无噪音、无创性和对实验过程中被试动作不会过份敏感等优点,但也存在空间分辨率不高和校正算法有待进一步完善等方面的不足。未来fNIRS的研究可以与fMRI等其他成像技术进行结合,开展婴幼儿和特殊人群的认知神经科学研究以及自然情境下大脑认知的神经机制研究。 相似文献

In alphabetic writing systems, saccade amplitude (a close correlate of reading speed) is independent of font size, presumably because an increase in the angular size of letters is compensated for by a decrease of visual acuity with eccentricity. We propose that this invariance may (also) be due to the presence of spaces between words, guiding the eyes across a large range of font sizes. Here, we test whether saccade amplitude is also invariant against manipulations of font size during reading Chinese, a character-based writing system without spaces as explicit word boundaries for saccade-target selection. In contrast to word-spaced alphabetic writing systems, saccade amplitude decreased significantly with increased font size, leading to an increase in the number of fixations at the beginning of words and in the number of refixations. These results are consistent with a model which assumes that word beginning (rather than word center) is the default saccade target if the length of the parafoveal word is not available. 相似文献

This study examined Chinese university students' conceptualization of the meaning of work. One hundred and ninety students (93 male, 97 female) from Beijing, China, participated in the study. Prototype research methodology (J. Li, 2001) was used to explore the meaning of work and the associations among the identified meanings. Cluster analysis was used to organize the identified meanings into a structure consisting of lateral and hierarchical levels. The themes that emerged fell into 2 large categories named "ideal" and "reality." A series of superordinate-level and basic-level prototypes were found under each of these 2 categories. These prototypes reflected influences from both Chinese traditional and Western value orientations, as well as perceptions that are to be understood in the contemporary social and economic contexts of China. Implications for career development theory, research, and practice are discussed. 相似文献

Westerners habitually think in analytical ways, whereas East Asians tend to favor holistic styles of thinking. We replicated this difference but showed that it disappeared after control deprivation (Experiment 1). Brief experiences of control deprivation, which stimulate increased desire for control, caused Chinese participants to shift toward Western-style analytical thinking in multiple ways (Experiments 2-5). Western Caucasian participants also increased their use of analytical thinking after control deprivation (Experiment 6). Manipulations that required Chinese participants to think in Western, analytical ways caused their sense of personal control to increase (Experiments 7-9). Prolonged experiences of control deprivation, which past work suggested foster an attitude more akin to learned helplessness than striving for control, had the opposite effect of causing Chinese participants to shift back toward a strongly holistic style of thinking (Experiments 10-12). Taken together, the results support the reality of cultural differences in cognition but also the cross-cultural similarity of using analytical thinking when seeking to enhance personal control. 相似文献

Two types of the attentional network, alerting and orienting, help organisms respond to environmental events for survival in the temporal and spatial dimensions, respectively. Here, we applied chromatic flicker beyond the critical fusion frequency to address whether awareness was necessary for activation of the two attentional networks. We found that high-frequency chromatic flicker, despite its failure to reach awareness, produced the alerting and orienting effects, supporting the dissociation between attention and awareness. Furthermore, as the flicker frequency increased, the orienting effect attenuated whereas the alerting effect remained unchanged. According to the systematic decline in temporal frequency sensitivity across the visual hierarchy, this finding suggests that unconscious alerting might be associated with activity in earlier visual areas than unconscious orienting. Since high-frequency flicker has been demonstrated to only activate early visual cortex, we suppose that neural activation in early visual areas might be sufficient to activate the two attentional networks. 相似文献

The limited capacity of visual working memory (VWM) requires the existence of an efficient information selection mechanism.
While it has been shown that under low VWM load, an irrelevant simple feature can be processed, its fate under high load (e.g.,
six objects) remains unclear. We explored this issue by probing the “irrelevant-change distracting effect,” in which the change
of a stored irrelevant feature affects performance. Simple colored shapes were used as stimuli, with color as the target.
Using a whole-probe method (presenting six objects in both the memory and test arrays), in Experiment 1 we found that a change to one of the six shapes led to a significant distracting effect. Using a partial-probe method (presenting
the probe either at the screen center or at a location selected from the memory array), in Experiment 2 we showed the distracting effect again. These results suggest that irrelevant simple features can be stored into VWM, regardless
of memory load. 相似文献

"Heartwarming memories: Nostalgia maintains physiological comfort": Correction to Zhou et al. (2012)
Reports an error in "Heartwarming Memories: Nostalgia Maintains Physiological Comfort" by Xinyue Zhou, Tim Wildschut, Constantine Sedikides, Xiaoxi Chen and Ad J. J. M. Vingerhoets (Emotion, Advanced Online Publication, Mar 5, 2012, np). In the article, the last sentence was incorrect. The corrected sentence is provided in the erratum. (The following abstract of the original article appeared in record 2012-05385-001.) Nostalgia, a sentimental longing or wistful affection for the past, is a predominantly positive and social emotion. Recent evidence suggests that nostalgia maintains psychological comfort. Here, we propose, and document in five methodologically diverse studies, a broader homeostatic function for nostalgia that also encompasses the maintenance of physiological comfort. We show that nostalgia-an emotion with a strong connotation of warmth-is triggered by coldness. Participants reported stronger nostalgia on colder (vs. warmer) days and in a cold (vs. neutral or warm) room. Nostalgia, in turn, modulates the interoceptive feeling of temperature. Higher levels of music-evoked nostalgia predicted increased physical warmth, and participants who recalled a nostalgic (vs. ordinary autobiographical) event perceived ambient temperature as higher. Finally, and consistent with the close central nervous system integration of temperature and pain sensations, participants who recalled a nostalgic (vs. ordinary autobiographical) event evinced greater tolerance to noxious cold.
