The purpose of the proposed study was to replicate and extend the findings of Perez-Gonzalez, Garcia-Asenjo, Williams, & Carnerero, (2007) by evaluating whether teaching sets of original and reverse intraverbals from the same category (e.g., animals sounds) will result in the emergence of novel, reverse intraverbals. Three children diagnosed with an autism spectrum disorder participated in the study. A multiple baseline across conditions design with a constant-series control (for two participants only) was used to evaluate the effects of training original and reverse intraverbals on subsequent trained and untrained, reverse intraverbals. All of the participants in the current evaluation mastered sets of original intraverbals in a relatively small number of training sessions. Participants acquired all trained intraverbals, however treatment (i.e., training reverse intraverbals) did not produce the emergence of novel untrained reverse intraverbals.
