The effects of listener and speaker training on emergent relations in children with autism.

The current study assessed the use of standard conditional discrimination (i.e., listener) and textual/tact (i.e., speaker) training in the establishment of equivalence classes containing dictated names, tacts/textual responses, pictures and printed words. Four children (ages 5 to 7 years) diagnosed with autism were taught to select pictures and printed words in the presence of their dictated names, and to emit the tact or textual response corresponding to a presented picture or printed word. Both speaker and listener training resulted in the formation of stimulus classes for 3 of 4 participants.
