The present study evaluated the effectiveness of stimulus equivalence procedures using the instructional protocols from the PEAK-E curriculum to develop the emergence of cause and effect relational responding in two children with autism. The procedures were taken from the PEAK-E program Transitivity: Multiple Actions & Outcomes-9p to aid in clinical replication. This study utilized a multiple baseline design across participants to evaluate the functional relationship between cause and effect relations. The results suggested that direct training of an action (A) to an outcome (B) (A-B) and direct training of an outcome (B) with an action that is produced by the outcome (C) (B-C) was effective for both participants. Following A-B and B-C training, the participants demonstrated emergent relations and untrained action (A) to action (C) relations which are consistent with transitivity. The results demonstrate efficacy of stimulus equivalence procedures for training cause and effect skills as well as the PEAK-E curriculum
