people struggle to learn how to recognise and decode printed words so they cannot read as accurately/fluently as others.
have poor verbal STM which has been shown using phonological similarity effect and word length effect.
McDougall 1994
divided 90 children to three reading abilities.
poor readers had lower memory spans and a slower reading rate, good readers can articulate words quickly leading to greater number of words being processed in STM.
poo readers sound out words slower so fewer words are held in STM
basic inefficiency in phonological processing and storage could explain dyslexia
Alloway (2009)
children with dyslexia have difficulty processing and remembering speech sounds due to poor working memory.
cannot hold speech sounds for long enough to be able to bind them to form a word.
investigated 46 children 6-11 year olds with a reading disability, finding that STM deficits could be cause of reading problems
what impact does the research into dyslexia do?
suggests there's an underlying cognitive impairment that leads to shorter memory span and difficulty processing/storing verbal info in STM.
not entirely sure on what role verbal memory plays in causing dyslexia2
