Promoting Generalized Advanced Language Skills of Children in Intensive Behavioral Intervention with Promoting the Emergence of Advanced Knowledge Generalization Module (PEAK-G).

The Promoting the Emergence of Advanced Knowledge Relational Training System Generalization Module (PEAK-G; Dixon, 2014) was used within a community-based intensive behavioral intervention (IBI) program to enhance the generalized advanced language skills of children diagnosed with autism spectrum disorder. Four multiple-baseline, across-behaviors designs were used to assess the effectiveness of the PEAK-G "train and test" discrete trial training (DTT) method on directly trained and generalized language skills. After implementing PEAK-G, directly trained language skills increased for all participants, and generalization to test stimuli was observed for two participants, with some generalization observed for a third participant. These data suggest that PEAK-G may be a viable option for community-based practitioners to promote more advanced generalized language skills to children who have mastered early language skills.
