In a sample of 976 consecutive cases derived from the recent world-wide Field Trial of Autism and other Pervasive Developmental Disorders, we tested the accuracy of the 15 ICD-10 criteria for the diagnosis of Autism, by comparing neural network models (NN) to more conventional multivariate competitors, namely, linear and quadratic discriminant function analyses and logistic regression. NNs were less accurate than competitors, both in terms of cross-validation results as well as in levels of shrinkage from training to test conditions. The clinical research implications of these results are discussed. 相似文献

Increasing the number of available sources of information may impair or facilitate performance, depending on the capacity
of the processing system. Tests performed on response time distributions are proving to be useful tools in determining the
workload capacity (as well as other properties) of cognitive systems. In this article, we develop a framework and relevant
mathematical formulae that represent different capacity assays (Miller’s race model bound, Grice’s bound, and Townsend’s capacity
coefficient) in the same space. The new space allows a direct comparison between the distinct bounds and the capacity coefficient
values and helps explicate the relationships among the different measures. An analogous common space is proposed for the AND
paradigm, relating the capacity index to the Colonius–Vorberg bounds. We illustrate the effectiveness of the unified spaces
by presenting data from two simulated models (standard parallel, coactive) and a prototypical visual detection experiment.
A conversion table for the unified spaces is provided. 相似文献
