Abstract
Previous research has reported that learning disabled (LD) and attention deficit disorder with hyperactivity (ADD-H) children habituate more rapidly to a stimulus than do control children. The information that was encoded in the habituation task was assessed in the present study. Although the results indicated that LD and ADD-H children habituate more rapidly, they also encode fewer aspects of the stimulus field. The limited encoding skills of these children were attributed to the attention difficulties associated with these disorders.
