Tests of phonology, semantics, and syntax were administered to 52 preschool
children (19 girls and 33 boys, age 4-6 years) with moderate to severe spe
ech sound disorders. The children's performance on these tests was used to
predict language, reading, and spelling abilities at school age (age 8-11 y
ears). Language impairment at school age was related to poor performance on
preschool tests of syntax and nonsense word repetition, while reading impa
irment was predicted by poor performance in all preschool rest domains (pho
nology, semantics, and syntax). In contrast, spelling impairment was predic
ted by deficits in preschool tests of phonological processing as measured b
y the Word Discrimination subtest of the Test of Language Development - Pri
mary 2. Family history for speech and language disorders did not predict la
nguage, reading, or spelling impairment at school age. However, family hist
ory for reading disorders was a good predictor of school-age spelling diffi
culties. (C) 2000 by Elsevier Science Inc.
