RESUMEN
We employed a multiple probe design to test the effects of an accelerated auditory matching protocol with five toddlers receiving early intervention services (four males, one female) for developmental delays. All participants emitted poorly articulated vocal mands and tacts. The dependent variables were the number of full echoics, partial echoics, and incorrect responses within a set of 20 two-syllable words. The independent variable was an accelerated Auditory Matching Protocol that targets auditory discrimination using an iPad App. Each phase of the protocol targets different sound discriminations with growing complexity. Four out of five participants emitted more full or partial echoic responses upon mastery of the Auditory Matching Protocol. Moreover, compared to those who received the full dosage of the standard Auditory Matching Protocol in previous studies, the participants in this study required fewer learn units to master all phases and to demonstrate improvement.
