The Use of Self-Study and Matrix Training to Teach Sign Language

Augmentative and alternative communication (AAC) systems allow individuals with vocal speech delays to meet their wants and needs. However, when signs are used as AAC, the implementers and caregivers must also learn signs. Longo et al. Behavioral Interventions, 37(3), 713-731 (2022) found that a self-study training (SST) in which adult participants observed videos paired with text was both efficacious and efficient in teaching eight component and 16 compound signs, arranged in a matrix. We systematically replicated SST, with changes to the matrix design and targets evaluated. The dependent variables were text-sign intraverbal and sign-vocal tacts for component and compound targets. Performance in a role play condition was also evaluated before and after training. SST was implemented with three adult participants using a multiple probe design across behaviors (submatrices). For the first two participants, SST of six compound, diagonal targets led to the acquisition of 30 untrained compounds and 12 component targets across modalities (i.e., text-sign intraverbals, sign-vocal tacts, listener responses) and contexts (i.e., role play). Similar results were obtained with the third participant, though acquisition of submatrix 2 was observed following intervention with submatrix 1. These results have implications for designing training to support implementers teaching sign as AAC.
