For individuals who have complex communication needs and for the interventionists who work with them, the collection of empirically derived data that support the use of an intervention approach is critical. The purposes of this study were to continue building an empirically derived base of support for, and to compare the relative effectiveness of two communication intervention strategies (i.e., PECS and the use of VOCA) with preschool children who have complex communication needs. Specific research questions were (a) Which communication strategy, PECS or VOCA, results in a more rapid rate of acquisition of requesting skills for preschool children ?, and (b) To what extent do communication behaviors utilizing PECS and VOCA generalize from a pull-out setting to the classroom setting? Results are discussed and clinical implications given.

- The Picture Exchange Communication System (PECS) (2009, unknown): “Because they were comparing two different augmentative methods, Adkins and Axelrod (2002) assessed for generalization of sign and PECS, while Bock et al. (2005) recorded rates of acquisition of requesting skills between PECS and VOCA.”
- Evaluating Picture Exchange and the iPad™ as a Speech Generating Device to Teach Communication to Young Children with Autism (2013, background): “Bock et al. (2005) compared acquisition rates of mands and device preferences of six four-year-old boys diagnosed with a developmental disability and found that three children acquired mands using PECS at a slightly faster rate, while three children acquired mands using both devices at equal levels.”
