AAC commentary

Since AAC is an independent area  in assistive technology, I need to separate AAC area from the review.

 A precise definition of AAC?

AAC is an area of inquiry and practice emphasizing “the supplementation or replacement of natural speech and/or writing using aided and/ or unaided symbols…” (p.524).

“What are the consequences of a child’s profound impairment in joint attention for an interventionist attempting to introduce a visual-based AAC system? ” (p.139, )

Individuals with autism have relatively stronger visual-spatial abilities (Koul, Schlosser, & Sancibrian). However, the relative strength of children with autism in visual-spatial abilities may be at least partly mitigated by a profound disturbance of joint attention skill development (Mundy, Sigman, & Kasari, 1990).

Clearly much remains to be done to measure the impact of impaired joint attention on children’s use of AAC system.
