Hyperlexia
Comprehension Difficulties
On average, students with a prior Hyperlexia diagnosis who received Visualizing and Verbalizing instruction achieved significant improvements in comprehension. They made large (statistically significant) standard score changes on all measures. Additionally, 9-point percentile increases in receptive (Vocabulary) and expressive (Word Opposites) vocabulary put these students within the normal range (25th–75th percentile).
