Situation theory has been developed over the last decade and various versions of the theory have been applied to a number of linguistic issues. However, not much work has been done in regard to its computational aspects. In this paper, we review the existing approaches towards `computational situation theory' with considerable emphasis on our own research.
One of the great challenges of the new millennium is the continuing search of how the mind works. Although a relatively young field, the study of neuropragmatics can greatly contribute to this search by its interdisciplinary nature, the possibility to be applied to different research meth-ods and by the opportunity to study its nature by taking vastly different perspectives.
We offer a preliminary account of the information-based aspects of punctuation marks. We give our initial treatment within the Discourse Representation Theory and its segmented version. We hypothesize that this work will be useful in classifying the informational contributions of punctuation marks and bringing them to bear on the semantic characterization of written discourse.
Strawson proposed in the early seventies an attractive threefold distinction regarding how context bears on the meaning of `what is said' when a sentence is uttered. The proposed scheme is somewhat crude and, being aware of this aspect, Strawson himself raised various points to make it more adequate. In this paper, we review the scheme of Strawson, note his concerns, and add some of our own. However, our main point is to defend the essence of Strawson's approach and to recommend it as a starting point for research into intended meaning and context.
Most work on evolving cooperation in the Prisoner's Dilemma treats the non-iterated game as an undesirable simple case that should be risen above. It has been taken as a given that populations evolving to play the non-iterated game will always converge on defection. This paper questions this assumption, and demonstrates that organizing a population spatially dramatically changes the nature of the game and allows cooperation to emerge.
In 1857 Helmholtz proposed that the ear contained an array of sympathetic resonators, like piano strings, which served to give the ear its fine frequency discrimination. Since the discovery that most healthy human ears emit faint, pure tones (spontaneous otoacoustic emissions), it has been possible to view these narrowband signals as the continuous ringing of the resonant elements. But what are the elements? We note that motile outer hair cells lie in a precise crystal-like array with their sensitive stereocilia in contact with the gelatinous tectorial membrane. This paper therefore proposes that ripples on the surface of the tectorial membrane propagate to and fro between neighbouring cells. The resulting array of active resonators accounts for spontaneous emissions, the shape of the ear’s tuning curve, cochlear echoes, and could rela...
This a review of Logic Primer, by Colin Allen and Michael Hand, published by MIT Press in 1992.
The principal problem of consciousness is how brain processes cause subjective awareness. Since this problem involves subjectivity, ordinary scientific methods, applicable only to objective phenomena, cannot be used. Instead, by parallel application of phenomenological and scientific methods, we may establish a correspondence between the subjective and the objective. This correspondence is effected by the construction of a theoretical entity, essentially an elementary unit of consciousness, the intensity of which corresponds to electrochemical activity in a synapse. Dendritic networks correspond to causal dependencies between these subjective units. Therefore, the structure of conscious experience is derived from synaptic connectivity. This parallel phenomenal/neural analysis provides a framework for the investigation of a number of pr...
This book contains a representationalist theory of self-consciousness and of the phenomenal first-person perspective. It draws on empirical data from the cognitive and neurosciences.
This essay is a defence of the traditional notion of qualia - as properties of consciousness that are ineffable, intrinsic, private and immediately apprehensible - against the eliminative attempts of Daniel Dennett in the influential article "Quining Qualia." It is suggested that a thorough exploration of the concept is an appropriate starting point for future explanations of qualia, and the essay ends with some possible explanations of the four traditional properties.
