The “language of the gods” is conceived as a kind of language more complex than what we associate with human tongues in the strict sense of the term. Certain arbitrary regularities throughout the rational disciplines appear to indicate the existence of this language. The present article explores this new concept and applies it in an attempt to provide a logical clarification of the notions of individual consciousness and physical reality. 相似文献

A computational model was developed to explain a pattern of results of fMRI activation in the intraparietal sulcus (IPS) supporting
visual working memory for multiobject scenes. The model is based on the hypothesis that dendrites of excitatory neurons are
major computational elements in the cortical circuit. Dendrites enable formation of a competitive queue that exhibits a gradient
of activity values for nodes encoding different objects, and this pattern is stored in working memory. In the model, brain
imaging data are interpreted as a consequence of blood flow arising from dendritic processing. Computer simulations showed
that the model successfully simulates data showing the involvement of inferior IPS in object individuation and spatial grouping
through representation of objects’ locations in space, along with the involvement of superior IPS in object identification
through representation of a set of objects’ features. The model exhibits a capacity limit due to the limited dynamic range
for nodes and the operation of lateral inhibition among them. The capacity limit is fixed in the inferior IPS regardless of
the objects’ complexity, due to the normalization of lateral inhibition, and variable in the superior IPS, due to the different
encoding demands for simple and complex shapes. Systematic variation in the strength of self-excitation enables an understanding
of the individual differences in working memory capacity. The model offers several testable predictions regarding the neural
basis of visual working memory. 相似文献

The classical theory of semantic information (ESI), as formulated by Bar-Hillel and Carnap in 1952, does not give a satisfactory account of the problem of what information,
if any, analytically and/or logically true sentences have to offer. According to ESI, analytically true sentences lack informational content, and any two analytically equivalent sentences convey the same piece
of information. This problem is connected with Cohen and Nagel’s paradox of inference: Since the conclusion of a valid argument
is contained in the premises, it fails to provide any novel information. Again, ESI does not give a satisfactory account of the paradox. In this paper I propose a solution based on the distinction between
empirical information and analytic information. Declarative sentences are informative due to their meanings. I construe meanings as structured hyperintensions, modelled in Transparent Intensional Logic as so-called constructions. These are abstract, algorithmically structured procedures whose constituents are sub-procedures. My main thesis is that
constructions are the vehicles of information. Hence, although analytically true sentences provide no empirical information about the state of the world, they convey analytic information, in the shape of constructions prescribing how to arrive at the truths in question. Moreover, even though analytically equivalent
sentences have equal empirical content, their analytic content may be different. Finally, though the empirical content of
the conclusion of a valid argument is contained in the premises, its analytic content may be different from the analytic content
of the premises and thus convey a new piece of information. 相似文献

An Extension of Multiple Correspondence Analysis for Identifying Heterogeneous Subgroups of Respondents 总被引:1,自引:0,他引:1
An extension of multiple correspondence analysis is proposed that takes into account cluster-level heterogeneity in respondents’
preferences/choices. The method involves combining multiple correspondence analysis and k-means in a unified framework. The former is used for uncovering a low-dimensional space of multivariate categorical variables
while the latter is used for identifying relatively homogeneous clusters of respondents. The proposed method offers an integrated
graphical display that provides information on cluster-based structures inherent in multivariate categorical data as well
as the interdependencies among the data. An empirical application is presented which demonstrates the usefulness of the proposed
method and how it compares to several extant approaches.
