Transfer of Mand Topographies to Tact Relations and Vice Versa in Two Vocal-Verbal Children with Autism

Skinner (1957) suggested that verbal responses learned as mands are not necessarily emitted in tact relations and vice versa. Previous empirical research has found that newly acquired mands and tacts can be functionally independent. The present study investigated 1) whether novel responses taught in mand relations would be emitted as tacts when opportunity for tacting was presented; 2) whether novel responses taught in tact relations would be emitted as mands when opportunity for manding was presented; and 3) whether the size of pre-experimental mand and tact repertoires affected the rate of acquisition and/or transfer. Two vocal-verbal children with autism were taught three novel responses as mands and three other responses as tacts. Mand topographies transferred to tact relations and tact topographies transferred to mand relations for both participants. Overall acquisition as well as transfer of mands and tacts was faster for the participant with an entering repertoire of approximately 175 mands and 175 tacts than for the participant with a repertoire of approximately 100 mands and 100 tacts.
