Abstract:
The present study was designed to assess the
acquisition of mand and tact responses as a result of mand or tact training. Three subjects were tauqht vocal responses corresponding to objects as requests (mands)or as labels (tacts). Responses in the untrained repertoire were also assessed. The results indicated that acquisition of a vocal mand repertoire facilitated acquisition of a vocal tact repertoire and vice versa. Implications concerning the separation of mand and tact repertoires are discussed. A technology for investigation of elementary verbal operants is presented.
