Rapid Sequential Processing in Dyslexic and Ordinary Readers

Abstract

42 dyslexic and 42 ordinary readers were given a rapid sequential short-term memory task using materials adapted from the Illinois Test of Psycho-linguistic Abilities Visual Sequential Memory subtest. Dyslexic readers performed at a similar level to ordinary readers. In Study 2, the same readers were given a 10-piece form board to complete as quickly as possible. Dyslexic readers were significantly slower on this task. Since short-term memory was not a feature of the second task, it was reasoned that short-term memory problems were unlikely to be a feature of dyslexics' performances on rapid sequential processing tasks.
