However, the relatively lengthy time course of reinforcement-
reduction packages such as that described by Luiselli (1990) may be
impractical in family settings. For family members, such necessary adjunctive
skills as attention-extinction or contingent physical management may present
formidable obstacles, as well as challenging community acceptance for extended
periods. It is also possible that nonaversive behavior reduction technologies
may involve caregiver effort requirements that can only be demonstrably met
in professionally staffed and supervised settings.
