This study examined the feasibility of teaching phonological manipulat
ion skills to preschool children with disabilities. Forty-seven childr
en, 4-6 years old, enrolled in a special education preschool, were ran
domly assigned to receive training in one of three categories of phono
logical tasks (rhyming, blending, and segmenting) ora control group. R
esults indicated that children were able to make significant progress
in each experimental category, but that they demonstrated little or no
generalization either within a category (e.g., from one type of blend
ing task to another type of blending task) or between categories (e.g.
, from blending to segmenting). Although the children's level of cogni
tive development significantly predicted some learning outcomes, it di
d not appear to limit the learning of phonological tasks.
