ABSTRACT

The purpose of this study was to examine effects of listener training on emergent selection as listener responses and intraverbal as speaker responses using stimuli within equivalent relations. Two 4 to 5 year old children with developmental disabilites participated in the study. A multiple baseline across participants with multiple probes design was used. Stimulus classes used were vocal stimuli of names of occupations, A; visual stimuli representing the occupations, B; vocal stimuli describing functions of the occupations, C; and visual stimuli depicting functions of the occupation, D. Listener training were provided within A-B, C-D relations. Derived listener responses within A-D relation and interverbal as speaker responses within A-C relations were tested. The results showed that the two participants demonstrated targeted emergent listener and intraverbal responses. The results were discussed within stimulus equivalence paradigm.
