Abstract
With mental ages partialled out, the correlation of −0.25 between perceptual error scores of 102 remedial readers on the Minnesota Percepto-Diagnostic Test and Woodcock Reading Mastery Tests was not significant. Intra-group analysis of scores on reproductions showed that those in the organic classification made significantly more errors on the horizontal arrow figure. Inter-group analysis indicated significant differences among primary, secondary, and organic classifications with the organic producing the most errors on the horizontal arrow figure. Inter-group analysis of brain-damage indicators yielded no significant differences; inter-group analysis showed that those assigned the organic classifications made significantly more errors in distortion of dots.
