Specific Deficits in Component Reading and Language Skills: Genetic and Environmental Influences.

Olson, Richard; And Others

Journal of Learning Disabilities, v22 n6 p339-48 Jun-Jul 1989

Word recognition data from identical and fraternal twins and siblings (N=172) indicated that the phonological coding deficit of children with reading disabilities was highly heritable. Orthographic coding was not significantly heritable. Poor readers with low IQs were superior to similar reading but average IQ readers in phonological coding. (Author/DB)
