Sentence processing in language-impaired children under conditions of filtering and time compression

  • Rachel E. Stark (a1) and James W. Montgomery (a1)

Abstract

Nineteen language-impaired (LI) and 20 language-normal (LN) children participated in an on-line word-monitoring task. Words were presented in lists and in sentences readily comprehended by younger children. The sentences were unaltered, tow-pass filtered, and time- compressed. Both groups had shorter mean response times (MRTs), but lower accuracy, for words in sentences than words in lists. The LI children had significantly longer MRTs under sentence conditions and lower accuracy overall than the LN children. Filtering had an adverse effect upon accuracy and MRT for both subject groups. Time compression did not, suggesting that the reduction in high-frequency information and the rate of presentation exert different effects. Subject differences in attention, as well as in linguistic competence and motor control, may have influenced word-monitoring performance.
