Further evaluation of language skills correlated with discriminated responding in multiple schedule arrangements

Multiple schedule treatments are frequently used to thin the reinforcement schedule for functional communication responses (FCR) following functional communication training. Multiple schedules are often highly effective at decreasing FCR rates by establishing stimulus control. In some cases, individuals do not readily discriminate between reinforcement and extinction components. Previous research has shown that receptive and expressive color identification are strongly correlated with discriminated responding in a multiple schedule. In this study, we replicated this research by evaluating how color-related skills correlate with discriminated responding in a multiple schedule. In addition, using a standardized assessment, we examined the role of receptive and expressive language skills on discriminated responding in a multiple schedule. For our 11 participants, we found that expressive color identification correlated with discriminated responding in a multiple schedule. Furthermore, when we more broadly examined participants' language skills, we found a stronger correlation between language and discriminated responding.
