Defries, J. C.; And Others

Reading and Writing: An Interdisciplinary Journal, v3 n3-4 p271-83 Dec 1991

Fits spelling data from identical and fraternal twins to a basic multiple regression model. Finds that about 60% of the deficit of probands was due to heritable influences. Finds a nonsignificant sex difference. Suggests collaborative analyses of data from additional twin studies of reading disability to facilitate more rigorous tests. (RS)
