隔区或皮质顶叶损毁对大鼠空间认知能力的影响及大鼠搜索策略差异的研究 总被引:4,自引:0,他引:4
本研究的目的是探讨隔区或皮质顶叶在大鼠空间认知加工中的作用。实验观察到隔区或皮质顶叶损毁大鼠Morris迷宫学习或记忆作业成绩显著低于控制组,并发现隔区损毁大鼠主要采用与皮质顶叶或控制组不同的“非国类”搜索策略。搜索策略的差异提示:隔区和皮质顶叶在大鼠图认知加工系统中处于不同的功能层次,隔区具有更重要的作用。 相似文献

独生与非独生儿童认知发展的比较研究(广州市) 总被引:1,自引:0,他引:1
为了研究中国独生子女政策可能造成的独生和非独生儿童的认知能力的差别,分别在广州七所小学一年级和五年级中选择了146名和171名独生与非独生儿童。用11项认知能力测验对这些儿童进行测查。一年级独生儿童在言语记忆和一般常识项目上的成绩优于非独生儿童。研究认为,一年级独生儿童在与一般认知能力有关的项目上具有优势。而五年级的独生儿童在认知作业成绩上,没有表现出显著性的优势。另外,独生男童在一般常识方面优于独生女童。作者用独生儿童受到较大的父母关注和投资来解释一年级独生对非独生儿童在认知方面的优势。随着儿童的自然成熟和学业教育,两者之间的差距会逐渐缩小,从而使五年级独生儿童未能在认知方面表现出明显的优势。 相似文献

One of the most controversial, if not the most controversial, aspect of behaviorism is its claims (actual and putative) concerning cognition. Part of this controversy is caused by egregious exegetical errors on the part of Skinner's critics. Critics can then easily refute behaviorism by attributing these problematic claims to Skinner. This paper attempts to faithfully describe Skinner's claims regarding cognition. Skinner advances several arguments regarding the role of cognitions in human behavior and in the science of human behavior. We suggest that there are two distinct kinds of claims in this web: 1) claims regarding the proper relation between science and cognitions and 2) claims regarding the status of cognitions as natural events. Due to the multiplicity and interdependence of many of these arguments, it is best to view Skinner's position on cognition as consisting of a web of interdependent claims. 相似文献

采用认知测试、查阅人类学资料、现场调查和谈话等多种方法,探讨了我国不同生产方式、不同地区和不同民族460名成人的具体认知、抽象认知和认知方式及其与生态文化因素的关系。研究结果基本支持了我们理论上所假设的社会文化因素与具体认知操作、抽象认知操作、认知方式的关系,即狩猎和城市社会的生态环境和生产方式对人施加一种生态压力,增进其个体的具体的和抽象的认知,促使其抽象型认知方式的形成;而在捕鱼、游牧和农耕社会的生态环境和生产方式的作用下,个体倾向于较低水平的具体和抽象认知操作以及具体型的认知方式。紧密的社会结构和强调服从的社会化过程,与其个体较低水平的具体和抽象认知及具体型的认知方式相关联;而松散的社会结构和强调自主性的社会化过程,与较高水平具体和抽象认知操作、抽象型的认知方式相联系。正规教育等现代化因素是促进人认知,特别是抽象认知的有力因素。 相似文献

Abstract. Revolutionary developments in both science and theology are moving the relation between the two far beyond the nineteenth-century “warfare” model. Both scientists and theologians are engaged in a common search for shared understanding. Eight models of interaction are outlined: scientism, scientific imperialism, ecclesiastical authoritarianism, scientific creationism, the two-language theory, hypothetical consonance, ethical overlap, and New Age spirituality. Developments in hypothetical consonance are explored in the work of various scholars, including Ian Barbour, Philip Clayton, Paul Davies, Willem Drees, Langdon Gilkey, Philip Hefner, Nancey Murphy, Wolfhart Pannenberg, Arthur Peacocke, John Polkinghorne, Robert John Russell, Thomas Torrence and Wenzel van Huyssteen. 相似文献

A new model, called acceleration model, is proposed in the framework of the heterogenous case of the graded response model, based on processing functions defined for a finite or enumerable number of steps. The model is expected to be useful in cognitive assessment, as well as in more traditional areas of application of latent trait models. Criteria for evaluating models are proposed, and soundness and robustness of the acceleration model are discussed. Graded response models based on individual choice behavior are also discussed, and criticisms on model selection in terms of fitnesses of models to the data are also given.This research was supported by the Office of Naval Research (N00014-90-J-1456). 相似文献

Observations of eye movements of young children in a modified preferential looking task suggest a change in the visual looking pattern taking place during a very brief time between 32 and 33 months of age. In the younger children, a grating stimulus elicited eye movements towards the target followed by a few seconds of focused attention; in the older children a visual avoidance behavior was observed where subjects looked consistently in the opposite direction of the target. An analysis of video recordings suggests that this avoidance pattern was a composite of a very brief initial target-directed eyemovement which was quickly arrested, and followed by eye movements in the opposite direction, initiating a search of the visual scene. 相似文献

This essay addresses the insufficiency of modern science as the solution to the problems of human life. It is a critique of community theory and a constructivist proposal for a synthesis of the individuality and collectivity solutions to the Paradox of the One and the Many—designated as the Third Position. The Third Position is necessary for the postmodern period for there is a need to incorporate the goal of Equality (or Justice) into a paradigm based on Liberty and Fraternity. The Third Position is also called the Just Community. To achieve the development of the new position (paradigm), a location-specific action research center is proposed based on the Woods Hole Marine Biological Laboratory (Kelly, 1970). Two examples of action research are described: aqualitative project to develop community within a parish that has served to advance the theory of the Just Community, and aquantitative project of community-level change-monitoring of social indicators and the use of dynamic modeling as a way to understand and simulate local community processes. The Society for Community Research and Action is urged to take specific actions to explore the development of a Woods Hole community research laboratory. 相似文献
