Systems measures of word use and differential diagnosis

This paper presents findings on the power of two systems measures of word use to discriminate four patient groups. The first is the slope of accumulated entropy or complexity of the sample (known to be logarithmic over time). The other is the average Poisson rate for the use of new words (known to be a Poisson process). The four groups consisted of cancer, depressed, paranoid, and somatization patients. The two word measures discriminate the first three groups from the fourth. There is evidence that larger samples will identify a similar discriminator for each of the first three groups from one another. The results are discussed in terms of how these methods may offer fresh insight into the relationship between language use and psychopathology.     

Grafting Modalities onto Substructural Implication Systems

We investigate the semantics of the logical systems obtained by introducing the modalities and into the family of substructural implication logics (including relevant, linear and intuitionistic implication). Then, in the spirit of the LDS (Labelled Deductive Systems) methodology, we "import" this semantics into the classical proof system KE. This leads to the formulation of a uniform labelled refutation system for the new logics which is a natural extension of a system for substructural implication developed by the first two authors in a previous paper.     

Correspondence Results for Relational Proof Systems with Application to the Lambek Calculus

We present a general framework for proof systems for relational theories. We discuss principles of the construction of deduction rules and correspondences reflecting relationships between semantics of relational logics and the rules of the respective proof systems. We illustrate the methods developed in the paper with examples relevant for the Lambek calculus and some of its extensions.     

DIMENSIONS OF LIFE: A SYSTEMS APPROACH TO THE INORGANIC AND THE ORGANIC IN PAUL TILLICH AND PIERRE TEILHARD DE CHARDIN

Abstract. Systems theory provides a surprisingly fruitful approach to several important ideas held in common by Paul Tillich and Pierre Teilhard de Chardin. These include complexity or organization as the key to understanding the distinction between the inorganic and the organic, and hierarchy or levels in complex systems. Teilhard and systems theorists accept hierarchy as fundamental. Tillich questions the concept and prefers “dimensions,” including the inorganic, organic, psychological, spiritual, and historical dimensions. Tillich's rejection of hierarchy is questioned, but significant correlations are discovered in the systems interpretation of the psychological and spiritual dimensions as well as in the use of “centeredness” by both thinkers.     

Adding pieces to the puzzle: a commentary

In Jensen's theme paper she did an excellent job of outlining and explaining ways in which motor developmentalists can use the tools of biomechanics and engineering to address research questions. We extend her thorough efforts in two ways. First, we highlight the communication value provided by the precision of biomechanics terminology, and second, we reinforce the need to embed motion (the kinematics and kinetics) in context and function in order to understand the complexity of behaviour. We illustrate how one biomechanical tool, mechanical models, can facilitate this and provide insight to the development of control. Copyright © 2005 John Wiley & Sons, Ltd.     

盲人的时间水平方向隐喻的通道特异性

通过2个实验, 考察了感觉通道对盲人的时间水平方向隐喻的影响。实验1发现, 盲人只在动作水平上存在同阅读方向一致的时间水平方向隐喻, 对表征过去的词或句子按左键反应和对表征将来的词或句子按右键反应时更快, 表明盲人用于隐喻时间的空间信息是知觉性的。实验2比较了明眼人可视组被试和明眼人遮眼组被试的时间空间隐喻, 发现明眼人可视组被试只在动作水平上存在时间水平方向隐喻, 明眼人遮眼组被试只在刺激在右侧时呈现才出现动作水平的时间水平方向隐喻。综合分析表明, 盲人和明眼人可视组被试的反应更为接近, 表明盲人的时间空间隐喻未受听觉信息的影响。盲人通过运动通道获得的空间认知代偿了视觉通道信息的缺失。     

知觉符号理论及其研究范式

Moving to higher ground: The dynamic field theory and the dynamics of visual cognition

In the present report, we describe a new dynamic field theory that captures the dynamics of visuo-spatial cognition. This theory grew out of the dynamic systems approach to motor control and development, and is grounded in neural principles. The initial application of dynamic field theory to issues in visuo-spatial cognition extended concepts of the motor approach to decision making in a sensori-motor context, and, more recently, to the dynamics of spatial cognition. Here we extend these concepts still further to address topics in visual cognition, including visual working memory for non-spatial object properties, the processes that underlie change detection, and the ‘binding problem’ in vision. In each case, we demonstrate that the general principles of the dynamic field approach can unify findings in the literature and generate novel predictions. We contend that the application of these concepts to visual cognition avoids the pitfalls of reductionist approaches in cognitive science, and points toward a formal integration of brains, bodies, and behavior.
