[CALIBK12] [CSLA Research Update] Reading intervention study

[Lesley Farmer]

Educational "workouts" for the brain can boost reading abilityA
rigorous intervention program targeting students with dyslexia
effectively rewired their brains to work almost the same as children
who don't struggle with reading, Carnegie Mellon University researchers
reported. The changes, which appeared immediately after the 100-hour
intervention, remained for at least one year, brain scans of a sampling
of the students showed. The central finding was that prior to
instruction, the poor readers had significantly less activation than
good readers bilaterally in the parietal cortex. Immediately after
instruction, poor readers made substantial gains in reading ability,
and demonstrated significantly increased activation in the left angular
gyrus and the left superior parietal lobule. Activation in these
regions continued to increase among poor readers 1 year
post-remediation, resulting in a normalization of the activation. These
results are interpreted as reflecting changes in the processes involved
in word-level and sentence-level assembly. Areas of overactivation were
also found among poor readers in the medial frontal cortex, possibly
indicating a more effortful and attentionally guided reading
strategy.Ann Meyler, Timothy A. Keller, Vladimir L. Cherkassky, John
