An article by Horner et al, began with the statement that “In recent years, a broad-based movement has emerged in support of no aversive behavior management”. He asserted that “No aversive behavior management … has developed … as an alternative to the use of more extreme aversive events” and coined the phrase “positive behavior support” to refer to no aversive behavior-management procedures. They stated that “many people …
