Dyslexic Participants Show Intact Spontaneous Categorization Processes
Nikolopoulos, Dimitris S.; Pothos, Emmanuel M.
Dyslexia, v15 n3 p167-186 Aug 2009
We examine the performance of dyslexic participants on an unsupervised categorization task against that of matched non-dyslexic control participants. Unsupervised categorization is a cognitive process critical for conceptual development. Existing research in dyslexia has emphasized perceptual tasks and supervised categorization tasks (for which intact attentional processes are paramount), but there have been no studies on unsupervised categorization. Our investigation was based on Pothos and Chater's ("Cognit. Sci.," 2002; 26: 303-343) model of unsupervised categorization and the corresponding methodology for analysing results. Across all performance indices and various data-processing options, we could identify no difference between dyslexic and non-dyslexic participants. (Contains 5 tables and 4 figures.)
