Abstract

Research has shown that training diagonal targets in a matrix may result in correct responses to the nondiagonal targets within the same matrix and novel targets from a separate matrix. This study replicated prior research using matrix training to teach tact noun-verb combinations to 3 male participants with autism who use a speech generating device to communicate. Two matrices were constructed (Matrix 1 and Generalization Matrix), using mastered nouns and verbs. Following baseline, diagonal targets within Matrix 1 were trained. Posttests were conducted for the Generalization Matrix and Matrix 1. Two participants showed recombinative generalization within Matrix 1 and correct responding to all targets within the novel generalization matrix. For the 3rd participant, recombinative generalization was observed within Matrix 1. However, correct responding with the generalization matrix targets was only observed after training with 3 additional matrices. These results replicate and extend previous findings.
