Training and testing music skills in a boy with autism using a matching‐to‐sample format

A 16‐year old boy with autism was taught music skills using a matching to sample procedure. He was trained and subsequently tested for the formation of four 4‐member classes, including different visual music stimuli, and Norwegian and Vietnamese labels for different major and minor chords. Four different stimuli sets were trained both in one‐to‐many (OTM) and many‐to‐one (MTO) training structures. Further, we explored if the reaction times to comparison stimuli increased from training to testing. Results showed that the participant formed equivalence classes with music relations. Furthermore, there were small differences only between OTM and MTO with respect to stimulus equivalence responding. The reaction times to comparison stimuli increased from training to testing, and were most pronounced for the equivalence trials.
