Automatic Processing in Normal and Learning Disabled Children.
Hancock, Anne Campbell; Byrd, Diana
A study tested the hypothesis that learning disabled (LD), specifically reading disabled, children differ from "normal" children in their ability to acquire automatic perceptual processes. The subjects were 16 third grade and 15 sixth grade students, of whom 7 third grade and 3 sixth grade students were classified as LD. LaBerge's letter matching task, which involves identifying familiar and unfamiliar items, was presented to the children on an Apple II microcomputer. Reaction time and accuracy data were collected on three consecutive days. Analyses of correct reaction times data revealed a significant grade X day interaction. Simple effects tests indicated that only the reaction time of the third graders decreased across days. Predicted differences in the acquisition of automatic processes between LD and normal children were not found. A second study was conducted to replicate LaBerge and thus insure methodological equivalence. The procedure from the first experiment was repeated with 16 college students. Analyses of correct reaction time data replicated LaBerge's findings. (Author/FL)
