Abstract:
Sixteen residents at a group home for individuals with probable Alzheimer's disease took part in a person-recognition study. The stimulus was an unfamiliar individual to whom they were exposed for 8 weeks. For nine participants, approach tendency increased from Week 1 to the end of Week 4. Neither total time of exposure to a new person, nor cognitive status (by Mini-Mental State Examination [MMSE] score) predicted changes in approach behaviors over time. An innovative strategy for indexing person recognition is presented for possible use in future research studies with larger samples.
