Cognitive aging research suggests that environmental support can minimize m
emory failures in older adults. Similarly, designers of dwellings for frail
and dementing older populations try to provide prosthetic environments to
support greater independence. We review some of these research issues and d
esign practices from a human factors perspective. Early in the disease prc,
cess training approaches may be most effective, whereas later on there will
need to be more reliance on effective design. We also suggest a framework
for optimizing design across stakeholders and discuss some public policy is
sues.
