Synthesizing the Multiple-Probe Experimental Design With the PEAK Relational Training System in Applied Settings

The scientist-practitioner model necessitates embedding experimental designs within applied practice. This technical report describes a procedure for embedding a multiple-probe experimental design within the PEAK Relational Training System across all four PEAK modules. Baseline probes provide a direct test of target skills negatively endorsed within the PEAK assessment battery and can provide an estimate of skill acquisition in the absence of direct training. Temporal staggering of the probes maintains the fidelity of the experimental design and allows for the design to evolve along with learner skill acquisition. Achievement of mastery criteria demonstrates the efficacy of programming, and failure to achieve mastery can be remedied through programming adjustments that can be captured within the design. We additionally conducted a field test of the design with a child with disabilities, supporting the viability of this procedure within applied settings.
