RESUMO

The Picture Exchange Communication System (PECS) is a popular augmentative and alternative communication intervention for individuals with developmental disabilities that includes six, sequential phases of instruction. We systematically reviewed published and unpublished single-case PECS studies for details about the percentage of participants mastering PECS phases, how long it took participants to master PECS phases (in trials to mastery), and what constituted mastery of PECS phases. We found most participants mastered only the first two phases of PECS, and Phases I, II, and IV showed the slowest and widest variability in trials to mastery. Moreover, participants who were taught the third PECS phase learned to select from an average array of three symbols, which may limit the range of messages they can communicate. We discuss our findings in light of a few important limitations and provide directions for future researchers along with recommendations for professionals who might consider PECS.

RESUMO

Pivotal Response Treatment (PRT) is a popular intervention for improving targeted and untargeted communication skills for learners with autism. We systematically reviewed communication outcomes reported in experimental research to determine linguistic forms and verbal behavior functions associated with PRT. We found most researchers aggregated results or did not report sufficient detail to determine linguistic forms and/or verbal behavior functions. Generalization of communication skills to untargeted people, settings, materials, and/or activities was evident. However, only one study clearly indicated untargeted linguistic forms emerged following PRT, and no researchers described results that indicated improved generalized and collateral verbal behavior functions. We suggest PRT researchers more clearly define and report primary, generalized, and collateral communication-specific outcomes in order to advance research and practice.
