Da. Wilder et al., Brief functional analysis and treatment of bizarre vocalizations in an adult with schizophrenia, J APPL BE A, 34(1), 2001, pp. 65-68
Variables responsible for the maintenance of bizarre vocalizations emitted
by an adult diagnosed with schizophrenia were examined via a brief function
al analysis, and results suggested that the behavior was maintained by atte
ntion. A treatment consisting of extinction and differential reinforcement
of appropriate vocalizations was effective in reducing bizarre vocalization
s and increasing appropriate vocalizations. The use of functional analysis
methodology to examine variables that maintain problem behavior in this pop
ulation is discussed.
