Therapist-initiated vestibular stimulation was compared to self-initiated stimulation to determine their relative effects on vocalization in children with autism. Vocalizations produced during table-top activities were also compared to those produced during vestibular stimulation. Two children with autism participated in the study. Vestibular stimulation was provided by a hammock swing. All vocalizations were recorded during a total of thirteen 15-minute test sessions.

Results indicated that in this study: (a) There was no significant difference in quantity of vocalizations produced during self-initiated versus therapist-initiated vestibular stimulation, and (b) there was a significant increase in vocalizations during vestibular stimulation as compared to during table-top activities.
