A Picture-Aided Communication System Manager (PACSMan)
This research is supported by the Eunice Kennedy Shriver National Institute for Child Health and Human Development grant R42DC010365
The primary focus of this research is to develop and field test software for functional communication training for children with little or no functional language due to autism or other neurodevelopmental disorders. Aimed principally at behavior therapists, special educators, and speech/language professionals, the software will support implementation of augmentative/alternative communication (AAC) approaches that use pictures to aid functional communication. Picture-aided communication systems are now widely used in functional communication training, most notably in the widely used PECS (Picture Exchange Communication System).
The software will address three critical stages in such functional communication training:
- Establishing the first instances of reliable discrimination among pictures and corresponding objects
- Accelerating expansion of the picture-discrimination repertoire
- Establishing and expanding picture sequences to support progressively more capable picture-aided communication
The working title of the product is Picture-Aided Communication System Manager (PACSMan). The scientific foundation for PACSMan is extensive, deriving from dozens of publications in professional journals over the past three decades. The program will manage the therapist-child interface within a PECS-like teaching environment.
The software will:
- Display sequences of stimulus items and their configurations to be presented
- Allow the therapist to quickly and conveniently enter data corresponding to the child's behavior
- Make automated on-the-fly queries of an individual-child database in order make decisions concerning the nature of the teaching sequences (i.e., when to add new items, when to accelerate teaching, when to remediate, etc.), and generally support an ongoing process of optimizing individualized instruction in picture-aided communication.
