摘要：Although experimental analysis methodologies have been useful for identifying the function of a wide variety of target behaviors (e.g., Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994), only recently have such procedures been applied to verbal operants (Lerman et al., 2005). In the current study, we conducted a systematic replication of the methodology developed by Lerman et al. Participants were 4 children who had been diagnosed with developmental disabilities and who engaged in limited vocal behavior. The function of vocal behavior was assessed by exposing target vocal responses to experimental analyses. Results showed that experimental analyses were generally useful for identifying the functions of vocal behavior across all participants.
