Use of a multicomponent treatment for food refusal.

We examined the use of a multicomponent treatment for food refusal exhibited by a 5-year-old boy who had been diagnosed with mild to moderate mental retardation. Treatment consisted of access to highly preferred tangible items, which were removed contingent on problem behavior or not accepting a bite, and differential reinforcement of alternative behavior. Treatment resulted in an increase in food acceptance to 100% of bite offers and near-zero rates of problem behavior. In addition, the participant's caregivers were successfully trained to implement the treatment.

Clarifying an ambiguous functional analysis with matched and mismatched extinction procedures.

Results of functional analysis were ambiguous in suggesting that self-injurious behavior (SIB) was maintained by escape, sensory reinforcement, or both. To help clarify these results, we compared escape extinction, sensory extinction, and the combined treatments. Sensory extinction proved to be a necessary and sufficient treatment, whereas escape extinction failed to decrease SIB. These analyses helped to clarify the function of SIB and to identify an effective and efficient treatment.

The effects of noncontingent and contingent attention for self-injury, manding, and collateral responses.

To date, most functional analysis studies have focused on the effects of treatment contingencies on specific targeted aberrant and alternative responses. In the current investigation, the main and collateral effects of the assessment and treatment of attention-maintained self-injury were assessed. Specifically, we evaluated the effects of noncontingent and contingent social attention on four categories of behavior: self-injury, a novel mand, preexisting prosocial responses (e.g., babbling and reaching out), and other aberrant responses (i.e., aggression and destruction). Results suggested that self-injury, prosocial responses, and other aberrant behaviors were within the same functional response class. Possible impact of these results when selecting mands for functional communication training is discussed.
