Abstract

Due to the prevalence of language delays in children with ASD, it is important to provide effective treatment and ensure highly trained staff to implement language programs. Natural Language Paradigm (NLP) is a naturalistic approach that includes individualized motivating variables, natural reinforcers, and direct response to reinforcer contingencies to increase vocal communication and generalization of skills. Behavioral skills training (BST) is an effective strategy that uses instructions, modeling, rehearsal, and feedback to teach staff to implement specific programs. The current study replicated Seiverling et al. (2009) study on evaluating the effectiveness of using BST to train three staff to implement an NLP program for manding. A non-concurrent multiple baseline design across three participants was used to evaluate the effects of BST on the levels of correct implementation of NLP. Sessions were conducted with a confederate playing the role of the child. Probe and generalization sessions were conducted with an actual client. Results showed that participants increased the levels of correct NLP performance during post-training probes when compared to baseline. Additionally, staff displayed high levels of performance during the generalization probe. The current study demonstrates that BST was effective at training an NLP procedure for manding, and that generalization was achieved following the intervention.
