Perception2

The article is an overview of some central philosophical problems associated with perception. It discusses what distinguishes perception from other sensory capacities and from conception. It discusses anti‐individualism, a view according to which the nature of a perceptual state is dependent not just causally but for its identity or ‘essence’ on relations to a normal environment in which systems containing that state were formed. It discusses different views about epistemic warrant. By emphasising the deep ways in which human and animal perceptual systems, especially visual systems, are similar, it criticises a dominant view of the last century, in both philosophy and large parts of psychology, according to which a range of sophisticated supplementary abilities have to be learned before a child can perceive objective features of the physical world.     

Investigating and facilitating children's graphic, geographic, and spatial development: An illustration of Rodney R. Cocking's legacy

Presented here is a case history of an interdisciplinary program of research on children's graphic, geographic, and spatial development that integrates approaches from developmental psychology, geography, and education. Some of the theoretical and historical roots of this work are discussed, with a particular emphasis on the roles that Rodney R. Cocking played in the evolution of this work. Described are findings from basic research on children's developing understanding of place representations, such as maps, educational interventions designed for public television and elementary school classrooms, and efforts aimed at national educational reform. Taken together, the work illustrates Rodney Cocking's profound, diverse, and continuing legacy to the scholarship of the academy and to the lives of children.     

Representation of Game Algebras

We prove that every abstractly defined game algebra can be represented as an algebra of consistent pairs of monotone outcome relations over a game board. As a corollary we obtain Goranko's result that van Benthem's conjectured axiomatization for equivalent game terms is indeed complete.     

Visual Technologies, Cosmographies, and Our Sense of Place in the Universe

The first part of this paper surveys the visual technologies that have transformed the modern visual environment and argues for the relevance of their study to an understanding of modernity in general and to the field of religion and science in particular. The term cosmography is adopted for the visual and spatial manifestation of a worldview, and the importance of analyzing and advancing modern cosmography is asserted. In the second part, the focus shifts to one particular challenge presented by modern cosmography: how to represent and find visual meaning in the new range of size scales that have been offered up by the modern scientific worldview. Six strategies for representing and finding meaning in this new expanded picture of the universe are explored.     

Connecting the Many Levels and Facets of Cognitive Aging

Basic cognitive mechanisms, such as the abilities to briefly maintain, focus, and process information, decline with age. Related fields of cognitive aging research have been advancing rapidly, but mostly independently, at the biological, information processing, and behavioral levels. To facilitate integration, this article reviews research on cognitive aging at the different levels, and describes a recent integrative theory postulating that aging-related deficiencies in neurotransmission cause increased noise in information processing and less distinctive cortical representation, which in turn lead to cognitive deficits. Aging-related attenuation of catecholaminergic modulation can be modeled by lowering a neural network parameter to reduce the signal-to-noise ratio of information processing. The performance of such models is consistent with benchmark phenomena observed in humans, ranging from age differences in learning rate, asymptotic performance, and interference susceptibility to intra- and interindividual variability and ability dedifferentiation. Although the details of the conjectured sequence of effects linking neuromodulation to cognitive aging deficits await further empirical validation, cross-level theorizing of the kind illustrated here could foster the coevolution of related fields through cross-level data synthesis and hypothesis testing.     

A Radical Notion of EmbeddednessA Logically Necessary Precondition for Agency and Self-Awareness

The aim of this essay is to establish the logically necessary preconditions for the existence of self-awareness in an artificial or a natural agent. It examines the terms agent , situated , embodied , embedded , and representation as employed ubiquitously in cognitive science, attempting to clarify their meaning and the limits of their use. It discusses the minimal conditions for an agent's environment constituting a 'world' and rejects most, though not all, types of virtual world. It argues that to qualify as genuinely situated an agent should function in real time within the dynamic world we inhabit, or some close simulacrum of it. It shows that embodied agents will possess or evolve local coordinate systems, or points of view, locating, identifying, and interacting with objects relative to their current position in space-time, and it discusses various types of embodiment, arguing that most current situated and embodied systems are too limited to be candidates for even the most minimal claim to self-identity. It argues that a truly autonomous agent has to be active in its participation with the world, able to synthesize and order its internal representations from its own point of view, and that to do this effectively the agent will have to be embedded. To this end it proposes a six-point definition of embeddedness. Ultimately it argues for a philosophical-cum-cognitive-science model of the self that satisfies essential elements of both sets of definitions of the term.     

时间修饰词内隐记忆的实验研究

用词汇线索联想的内隐记忆实验范型,对48个时间修饰词进行概念启动效应的实验研究,探讨时间修饰词内隐记忆的特点和内隐时间表征存在的可能性。结果表明：学过的词和末学过的词之间词汇线索联想的启动值有显著差异;词汇线索联想和词汇线索回忆两种作业平均击中率的差异效应显著;被试完成两种作业依据的判定标准依次为：词的意义、词的时间属性(长度、时间单位)、过去生活经验等。对时间修饰词的内隐表征进行了初步讨论。     

中学生物理力学问题的分类及表征研究

采用自由分类和标签分类法,以16道中学物理力学应用题为实验材料,探讨不同学业水平中学生对物理问题的分类及表征差异,以及题目陈述方式(有无示意图)对分类的影响.结果发现: (1)自由分类实验中,学优生侧重于按问题的深层特征(物理原理表征)进行分类,学困生侧重于问题的表面特征(文字表征);题目陈述方式对优困生的分类时间和分类表征也有影响. (2)标签分类实验中,学优生的正确分类题目数量显著高于学困生,有示意图下学优生的正确分类题目数量显著高于无示意图下.
