Functional analysis and extinction of different behavior problems exhibited by the same individual

Specific extinction procedures were matched to the function of two target behaviors displayed by the same individual, with results indicating that the matched extinction procedure suppressed the behavior for which it was designed. One of the target behaviors was exposed to an irrelevant extinction procedure, which produced no beneficial effects. These results support previous research indicating the need to match extinction proce-dures to the function of problem behavior.
