A Descriptive Study of Hyperlexia in a Clinically Referred Sample of Children with Developmental Delays.

This study of hyperlexia in 80 children with developmental delays found no significant differences in the frequency of hyperlexia in girls compared with boys; a significantly elevated frequency of hyperlexia in children diagnosed with pervasive developmental disorders (PDD) compared with children with non-PDD diagnoses; and a similar range of IQ and developmental outcomes for children with and without hyperlexia.
