While often not professionally diagnosed with hyperlexia,
a small number of students who received instruction exhibited some
hyperlexic characteristics. According to the American Hyperlexia Association,
hyperlexia is a syndrome observed in children who have a precocious ability
to read words (far above what is expected at their chronological age) or
an intense fascination with letters or numbers, significant difficulty in
understanding verbal language, and abnormal social skills (difficulty in
socializing and interacting appropriately with people). The following is
based on students with above average decoding (at or above the 50th percentile)14 and
poor listening comprehension (at or below the 25th percentile).15
