N2 - Reports of semantic dementia patients have shown more accurate identification and use for personal objects than unfamiliar analogs of the same objects (e.g., personal comb versus experimenter's comb) [Bozeat, S., Lambon Ralph, M. A., Patterson, K., & Hodges, J. R. (2002). The influence of personal familiarity and context on object use in semantic dementia. Neurocase, 8, 127-134; Snowden, J. S., Griffiths, H., & Neary, D. (1994). Semantic dementia: Autobiographical contribution to preservation of meaning. Cognitive Neuropsychology, 11, 265-288]. Despite potential clinical implications, the personal object advantage has not been explored in various dementia populations. Sixteen mild to moderate dementia patients were tested with 12-15 of their personal objects and laboratory analog objects. Four tasks were administered: Naming, Gesture, Semantic/Script Generation, and Personal Object Decision (i.e., Is this yours?). Although 25% of the sample performed at chance in identifying personal objects as their own, participants generated more specific information (t = 2.3, p = .03) and more accurate gestures (t = 2.4, p = .03) for personal objects. Thus, the personal object advantage was observed for script/semantic knowledge and movement sequences, and should be considered in residential planning for various dementia patients.
