Abstract
Responses to sound were observed in two groups of children. One was developmentally normal; the other was older but profoundly multihandicapped. The groups had developmental ages from 2 to 4 months, as assessed by the Kent Infant Developmental Scale (Katoff, Reuter, & Dunn, 1978). Stimuli were speech and random noise, both unfiltered and band-pass filtered at 2000 Hz, presented at 40, 60, and 80 dB HL. Responsiveness was determined from the confidence levels of observers' judgments of videotapes. Results showed that there were no significant differences between the subject groups. In both groups, however, responsiveness was dependent on hearing level and bandwidth but not on meaningfulness. The results support the practice of evaluating auditory responsiveness of multihandicapped children in relation to developmental age.
