The Use of Matrix Training to Teach Color-Shape Tacts to Children with Autism

Matrix training consists of preplanning instruction by arranging components of desired skills across a minimum of two axes. In the current study, three matrices were developed for each participant (e.g., Matrix 1, Generalization Matrix 1, and Generalization Matrix 2) with known color and shape components. Following baseline, nonoverlapping (i.e., diagonal) training was conducted with Matrix 1. Results of posttests were used to determine the extent of emergence of untrained color-shape combinations across all matrices. Results from all six participants indicated that mastery criteria were eventually met for Matrix 1. For five participants, mastery criteria were also eventually met for generalization matrices. Results replicate findings from prior studies and offer a simple approach for both testing emergence of untrained skills and remediating responding.
