title: Multivariate Analysis Of The Visual Information Processing Of Numbers.
abstract: This paper applies nonmetric multidimensional scaling and hierarchical clustering procedures to a confusion matrix of numbers. Two dimensions were interpreted "straight versus curved" and "locus of curvature," while four major clusters of numbers were developed. The results are applied to information processing as possible evidence of hierarchical structure in the pattern recognition of visual inputs.
