This study compared spoken word recognition in 39 reading disabled and
61 normally achieving children on a speech gating task and examined t
he relationships among speech recognition, phonemic awareness, and rea
ding. Children listened to increasingly longer segments of the speech
input from word onset and guessed the identity of the target word. Wor
ds were either high or low frequency and had few or many similarly sou
nding word neighbors in the listener's lexicon. Reading disabled child
ren needed more of the speech input than normally achieving peers to i
dentify target words with few similarly sounding neighbors. The amount
of speech input for recognition predicted the youngest children's rea
ding performance, after variance due to measures of phonemic awareness
and receptive vocabulary were accounted for. The argument is develope
d that spoken word recognition may be developmentally delayed in those
with reading disabilities and may play a causal role in these childre
n's failure to acquire adequate alphabetic knowledge.
