We investigated the relationship between reading and explicit and implicit categorical learning by comparing university students with poor reading to students with normal reading abilities on two categorical learning tasks. One categorical learning task involved sorting simple geometric shapes into two groups according to a unidimensional rule.…

This study examined differences between two subgroups of third grade dyslexics (n=72), either phonological dyslexics (lower phoneme awareness and expressive language) or delayed dyslexics (slower at processing printed words and letters but not at rapid automatic naming). Re-testing in fourth grade revealed that this classification produced…

This study used computer word games to train 35 dyslexic readers (mean age 13 years) in automaticity (speed and accuracy) of word recognition. After training, reaction time on the word vocalization and sentence comprehension tasks improved significantly for both trained and untrained stimuli. Results support the automaticity hypothesis.

Forty normal readers and 50 dyslexic children (age 9-14) were matched on reading level and intelligence quotient and tested. Analysis revealed 3 major subgroups: specific deficit in phonological processing of print (52 percent), deficits in processing both the phonological and orthographic features of printed words (24 percent), and phonological…
