新华社6月4日报道说,随着高考、中考考期临近,一些家长在关心孩子生活起居的同时,开始寻找“神仙”的保佑。进入五六月份以来,哈尔滨市及其周边寺庙香火格外旺盛。在哈尔滨极乐寺,双休日家长带着应考的孩子专程来烧香拜佛的络绎不绝。“许愿塔”前虔诚投掷硬币的人群中,同样围拢着学生模样的年轻人。距离哈 相似文献

声音诱发闪光错觉效应是典型的视听整合错觉现象, 是指当视觉闪光刺激与间隔100 ms内的听觉声音刺激不等数量呈现时, 被试知觉视觉闪光的数量与听觉声音的数量相等。声音诱发闪光错觉的影响因素既包括自下而上和自上而下的被试内差异因素, 也包括视听刺激依赖程度、视听整合的发展和视听刺激知觉敏感性等被试间差异因素。该效应的产生在时程上主要体现在早期加工阶段, 在脑区上主要涉及多处皮层及皮层下相关脑区。未来研究应进一步考察注意、奖赏和视听整合方式等认知加工对声音诱发闪光错觉的影响, 同时也应该关注声音诱发闪光错觉对记忆和学习的影响以及结合计算模型和神经科学的手段进一步探讨其认知神经机制。 相似文献

This study investigated gender differences in the relationship between creativity and academic achievement. A sample of 1082 primary students participated in this study in Beijing, China. Their age ranged between 8 and 15 years old (M = 10.41, SD = 0.99). Students’ creativity was measured by the Chinese version of the Torrance Test of Creative Thinking Figural Form A, and academic achievement was based on students’ self-reported grades of last semester. Results revealed that there was a significantly positive relationship between creativity and academic achievement, ranging from r = .07 to r = .21. Gender differences regarding which aspects of creativity were related to academic achievement were also found. Plausible explanations and implications of the findings in creativity research and education are discussed. 相似文献

In the present research, 6-month-old infants consistently searched for a tall toy behind a tall as opposed to a short occluder. However, when the same toy was hidden inside a tall or a short container, only older, 7.5-month-old infants searched for the tall toy inside the tall container. These and control results (1) confirm previous violation-of-expectation (VOE) findings of a décalage in infants' reasoning about height information in occlusion and containment events; (2) cast doubt on the suggestion that VOE tasks overestimate infants' cognitive abilities; and (3) support recent proposals that infants use their physical knowledge to guide their actions when task demands do not overwhelm their limited processing resources. 相似文献

Despite the impressive complexity and processing power of the human brain, it is severely capacity limited. Behavioral research has highlighted three major bottlenecks of information processing that can cripple our ability to consciously perceive, hold in mind, and act upon the visual world, illustrated by the attentional blink (AB), visual short-term memory (VSTM), and psychological refractory period (PRP) phenomena, respectively. A review of the neurobiological literature suggests that the capacity limit of VSTM storage is primarily localized to the posterior parietal and occipital cortex, whereas the AB and PRP are associated with partly overlapping fronto-parietal networks. The convergence of these two networks in the lateral frontal cortex points to this brain region as a putative neural locus of a common processing bottleneck for perception and action. 相似文献

宪政分权视野中的央地关系 总被引:11,自引:0,他引:11
在现代国家的宪政分权建构中,立法、行政、司法的横向分权与中央地方的纵向分权,具有同等重要的意义。宪政的纵向分权既需要在政治的层面上进行,也需要在行政的层面上落实。对于中国而言,解决好中央与地方的关系,必须坐实宪政的纵横双向分权,做到三个避免,注意三个关键问题,把握三个行为边界。 相似文献

企业的社会责任可以从责任相对人一企业利益相关者的权利的角度来界定.企业社会责任不仅仅要求企业超越简单的"股东利益最大化"的狭隘立场,而且也要超越狭隘的"社会利益最大化"的立场,以超越单纯经济计算的理性态度来维护和促进人类的某些基本价值的实现. 相似文献

The anterior cingulate cortex (ACC) participates in evaluating actions and outcomes. Little is known on how action-reward
values are processed in ACC and if the context in which actions are performed influences this processing. In the present article,
we report ACC unit activity of monkeys performing two tasks. The first task tested whether the encoding of reward values is
context dependent—that is, dependent on the size of the other rewards that are available in the current block of trials. The
second task tested whether unexpected events signaling a change in reward are represented. We show that the context created
by a block design (i.e., the context of possible alternative rewards) influences the encoding of reward values, even if no
decision or choice is required. ACC activity encodes the relative and not absolute expected reward values. Moreover, cingulate
activity signals and evaluates when reward expectations are violated by unexpected stimuli, indicating reward gains or losses. 相似文献
