These results suggest that a partial remediation of language - processing deficits, resulting in improved reading, ameliorates disrupted function in brain regions associated
with phonological processing and produces additional compensatory activation in other brain regions.
In the early to mid-2000s, research on the underlying basis of dyslexia pointed to a primary problem
with the phonological processing of speech sounds.
Not exact matches
The researchers studied MRI scans of preschool - age children and found that those
with a family history of dyslexia were less likely to demonstrate activation during
phonological processing and more likely to show decreases in gray matter than kids without that family history.
Persistence of
phonological processing deficits in college dyslexics
with age - appropriate reading skills.
The researchers looked at the brain activation of 50 soon - to - be kindergartners during a
phonological processing task — where the kids were asked to think about whether certain words started
with the same sound (for instance, «goat» and «gorilla,» or «bird» and «ant.»).
Developmental dyslexia, characterized by unexplained difficulty in reading, is associated
with behavioral deficits in
phonological processing.
Functional MRI was performed on 20 children
with dyslexia (8 — 12 years old) during
phonological processing before and after a remediation program focused on auditory
processing and oral language training.
Improvements in oral language ability and
phonological processing have been associated
with improvements in reading ability and are thought to subserve learning to read (2 — 4).
Functional neuroimaging studies have shown a deficit in the neural mechanisms underlying
phonological processing in children and adults
with dyslexia.
Many children
with learning disabilities have deficiencies in their ability to
process phonological information.
Research shows that dyslexia is now recognized as a primarily auditory disorder,
with weaknesses appearing specifically in
phonological processing.
Specifically, Cook found that
phonological processing («the ability to discriminate and detect differences in phonemes and speech sounds») and semantic
processing (encoding a word's meaning and making connections between the word and other words
with similar meanings) are well established by third grade.
Though prevailing models of dyslexia ascribe reading difficulties to poor
phonological processing, in recent years dyslexia has been increasingly associated
with deficits in visual attention (e.g., [15]--[24]-RRB- and poor oculomotor control [25]--[28], prompting a suggestion [5] that e-readers could be configured to reduce demands on visual attention and oculomotor control and thus make reading less of an effort for those impaired.
Her areas of expertise include child language delays and disorders, articulation and
phonological delays and disorders, social language / pragmatics delays (often seen
with autism spectrum disorders), stuttering and fluency disorders, and auditory
processing.
