Hyperlexia is the developmental disorder in which children decode word
s early but have significant impairments in aural and reading comprehe
nsion. Here, the literature describing hyperlexia is reviewed, includi
ng associated cognitive characteristics, neurobiological bases, and la
nguage and reading abilities. A study of 12 children with hyperlexia i
s summarized, illustrating the dissociation between decoding and compr
ehension skills, the superiority of phonologic over orthographic readi
ng strategies, and the limited use of meaningful context to aid decodi
ng. Implications for intervention with children with hyperlexia center
on the importance of targeting meaningful comprehension of both aural
and written language.
