Spaced retrieval training uses a schedule of practice trials distributed according to a learner's performance. The authors compared spaced retrieval to four alternative schedules of practice to determine whether it is more effective than other schedules for people with dementia. Participants practiced (a) pill names or (b) nonverbal sequences. Spaced retrieval did not produce long-term retention more often than other schedules of practice on either task. Participants with higher scores on one portion of the Hopkins Verbal Learning Test-Revised were more likely to show long-term retention of pill names regardless of schedule of practice (Experiment 1).
We evaluated a multicomponent intervention for agitated behavior in a man with probable Alzheimer's disease. Hypotheses about variables controlling his agitated behavior guided intervention design. Based on staff interviews, direct observations, and brief experimental probes, intervention components were chosen to increase rate of reinforcement and decrease aversive aspects of his job. Intervention reduced agitated behavior without disrupting his work rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
