Abstract:
Variables responsible for the maintenance of bizarre vocalizations emitted by an adult diagnosed with schizophrenia were examined via a brief functional analysis, and results suggested that the behavior was maintained by attention. A treatment consisting of extinction and differential reinforcement of appropriate vocalizations was effective in reducing bizarre vocalizations and increasing appropriate vocalizations. The use of functional analysis methodology to examine variables that maintain problem behavior in this population is discussed.
