Two groups of seven autistic children wore an auditory trainer for an average of 24 minutes per day over two 5-week periods interspersed with 5-week control periods in a time series design. Videotapes were coded for three attentional states (normal, withdrawn, attacking), for verbalization and signing, and for appropriate and acceptable behaviors. Results demonstrated a decrease in time spent withdrawn and increases in signing and in school-appropriate behavior. Results are interpreted as congruent with Katz's theory of reduced attention due to deficits in auditory conductance.
