Functional assessment and noncontingent reinforcement in the treatment of disruptive vocalization in elderly dementia patients.
Noncontingent reinforcement (NCR) was used as an intervention with 2 elderly dementia patients who engaged in disruptive vocalization. Several assessment procedures, including functional analysis, were conducted to identify reinforcing stimuli for use in the NCR intervention. Functional analyses and the NCR intervention were implemented in each participant's natural environment. NCR was effective in reducing disruptive vocalizations.
