The present study sought to demonstrate research based evidence that the more time spent in ABA therapy resulted in a an increase in IQ scores for participants. The research also sought to demonstrate that the PEAK Relational Training System can be effective as a treatment package. Previous research has evaluated the direct training protocol of the PEAK Relational Training System. The present study looked to evaluate the generalizing training protocols within the PEAK System, as well as support these previous findings. In Experiment 1 a quasi-experimental design was implemented and both control and treat-ment groups were exposed to testing measures. Results demonstrated greater gains made by the treatment group. Experiment 2 utilized a multiple baseline design across partici-pant and three designated generalized training programs from the PEAK System. Results showed a positive correlation between the PEAK Relational Training System and the par-ticipant’s IQ scores.
