Abstract
Objective: To assess an assistive-technology intervention for neurobehavioral change, coordinated with a Web-based data recording system.
Participant: Male, mid-thirties, with a complex history, having verbose speech subsequent to traumatic brain injury.
Design: BAB' single-case.
Intervention and Measures: The intervention (B and B' trials) was a digital recording of the participant's voice, stating "be brief," delivered at fixed intervals by a personal digital assistant. Utterance start and stop times were monitored with a wireless, Web-enabled device and were recorded in a server-side database.
Results: Utterance frequency did not change. However, the total utterance time was reduced during B trials, attributable to the reduced frequency of lengthier utterances.
Conclusions: The target behavior was modified successfully. The participant adopted a specific cue-appropriate strategy. Since a variety of alternative response strategies may be required of a person, given a range of context-specific social practices and community settings, the importance of context-sensitive assistive technology cue repertoires is discussed.
