An interesting article suggesting that
temporal processing (temporal sampling) may play a crucial roles in various forms of reading disabilities (dyslexia). IMHO this theory may explain a good portion of individuals with dyslexia, but no single theory or causal mechanism can account for the diversity of causes that have been suggested for severe reading disabilities. Nevertheless...the prominent role of temporal processing is interesing.
As per usual when I make a
research byte/brief post, if anyone would like to read the original article, I can share via email---with the understanding that the article is provided in exchange for a brief guest post about it's contents. :) (contact me at iap@earthlink.net if interested).

If nothing else, this article has some cool figures of models :)

Abstract Neural coding by brain oscillations is a major focus in neuroscience, with important implications for dyslexia research. Here, I argue that an oscillatory `temporal sampling' framework enables diverse data from developmental dyslexia to be drawn into an integrated theoretical framework. The core deficit in dyslexia is phonological. Temporal sampling of speech by neuroelectric oscillations that encode incoming information at different frequencies could explain the perceptual and phonological difficulties with syllables, rhymes and phonemes found in individuals with dyslexia. A conceptual framework based on oscillations that entrain to sensory input also has implications for other sensory theories of dyslexia, offering opportunities for integrating a diverse and confusing experimental literature.
