智力运动是以开发智力为目的且涉及到较多认知活动的竞技运动。研究表明, 长期的智力运动经验会影响专家在领域内任务中知觉及记忆的行为表现及其大脑活动。智力运动经验使专家知觉广度增大的同时, 促进专家对棋子关系进行整体性知觉加工, 且这一过程与颞顶联合区、缘上回、压后皮质、侧副沟、梭状回等区域有关; 在长时记忆中存储的具体(空间位置)及抽象信息(知识、策略、棋子关系等)是专家记忆优势发生的基础, 该过程与内侧颞叶、额叶和顶叶有关。未来研究可以从智力运动类型、创新实验范式, 结合测量设备及认知特点, 深入探讨智力运动专家整体知觉优势及记忆优势的神经机制, 为人工智能和技能训练等提供理论依据。 相似文献

ABSTRACTWe examined if language proficiency modulates performance in tasks that measure executive control in older Telugu-English bilinguals (n = 50, mean age = 57.15 years). We administered numerical Stroop task, Attention Network Task, Dimensional Change Card Sorting task, and stop-signal task that are known to tap into different aspects of executive functioning on healthy aging Telugu-English bilinguals. Second language (English) proficiency was calculated as a cumulative score that considered both subjective and objective measures of L2 fluency and use. Bilinguals were divided into two groups based on the cumulative score and compared on each task. We did not find any effect of language proficiency on any of the executive control measures. The additional Bayesian analysis also supported these findings. Therefore, the results do not support the claim that bilingual language proficiency modulates executive control, at least in the elderly population. We discuss the results with regard to the issue of bilingual advantage in executive control and the role of age and language use. 相似文献

Mostly invigorated by infrahumanisation theory, our knowledge on processes of dehumanisation in intergroup relations has grown considerably in the last decade. Building on these earlier endeavours, the present chapter reviews some recent empirical extensions that highlight the importance of differentiating between ingroup humanisation and outgroup dehumanisation because they are often moderated by specific variables. The role of these separate processes is discussed as a function of the main structural elements that define intergroup behaviour; that is, the defining boundaries of the groups, the relation between the groups at hand, and the ideologies of its members. Finally, the role of the different senses of humanness is discussed, suggesting that the folk conception of humanness differs between cultures. 相似文献

熟悉性对于自我信息加工优势的影响往往与自我相关性的作用交织在一起,从而使其成为该领域的一个研究重点和难点。文章分别介绍了自我参照效应、自我面孔和人名识别研究中对该问题进行考察的主要思路与发现。现有证据显示,熟悉性与自我特异性在自我信息的加工优势中是可分离的,从而表明自我信息所固有的高熟悉性可能并不是造成其具有加工优势的决定性因素。文章在展望部分将熟悉性进一步细分为材料的熟悉性与任务的熟悉性,并提出未来的研究应该特别注意考察任务熟悉性可能存在的影响作用。 相似文献

Studies have suggested that supramodal attentional resources are biased rightward due to asymmetric spatial fields of the two hemispheres. This bias has been observed especially in right-handed subjects. We presented left and right-handed subjects with brief uniform grey visual stimuli in either the left or right visual hemifield. Consistent with the proposed asymmetry in attentional resources, right-handed subjects estimated right hemifield targets as having a higher contrast than physically identical stimuli presented in the left hemifield. Left-handed participants did not show a systematic rightward or leftward bias. However, the group of left-handed participants also took part in a dichotic listening experiment whose results showed that visual bias score correlated positively with ear-advantage in dichotic listening. Our results are consistent with the view that supramodal processing resources are biased towards the right hemispace, and that this bias is influenced by handedness. 相似文献

The status-legitimacy hypothesis was tested by analyzing cross-national data about social inequality. Several indicators were used as indexes of social advantage: social class, personal income, and self-position in the social hierarchy. Moreover, inequality and freedom in nations, as indexed by Gini and by the human freedom index, were considered. Results from 36 nations worldwide showed no support for the status-legitimacy hypothesis. The perception that income distribution was fair tended to increase as social advantage increased. Moreover, national context increased the difference between advantaged and disadvantaged people in the perception of social fairness: Contrary to the status-legitimacy hypothesis, disadvantaged people were more likely than advantaged people to perceive income distribution as too large, and this difference increased in nations with greater freedom and equality. The implications for the status-legitimacy hypothesis are discussed. 相似文献

早期观点认为比喻性语言加工主要依赖右脑, 随着研究的深入, 右脑假说受到许多研究结果的挑战, 左脑参与比喻性语言的加工。同时, 左右脑语言区发挥各自不同的作用, 新的研究证实, 前额前部皮层同样参与比喻性语言的加工。比喻性语言的理解需要左右半球及前额皮层的共同激活, 同时对其加工还依赖左右半球的联合作用, 比喻性语言理解神经网络的建立需要新证据。 相似文献

Abstract. The dispute between theism and atheism has centered on whether there exists any entity that may be referred to as God and on how to explain life and the universe. As a consequence of this dispute and of the power of scientific explanations, religion may end up having less impact on society. The situation makes the following questions relevant: What are the advantages and disadvantages for society of downgrading religion? If the net effect of religion is considered to be positive, is it possible to counteract this trend? Moreover, examining the benefits of religion raises a further question: Is it possible to influence theology toward a stance with optimal utility for society? As a scientist writing from an atheist perspective, I argue that religion has a potential for serving society and that this advantage need not necessarily be sacrificed on the altar of science. 相似文献
