title: Partial remediation of speaker and listener behaviors in people with severe dementia.
abstract: We investigated the effects of contingent reinforcement (Intervention 1) and contingent reinforcement with modeling (Intervention 2) on speaker and listener behaviors in 5 people with severe dementia. Intervention 1 generally increased listener behavior; there was no clear effect on tacting, but echoic behavior increased in the one case investigated. Given the weak baseline repertoires of these clients and the paucity of other effective interventions, even the small increases in verbal behaviors found here are important. Further gains may be achieved, for example, if reinforcement opportunity per trial type were to be increased from one to several per day or if participants were trained to echo the listener stimulus in mand compliance tasks.
