Home-like architectural features of residential environments

Adults who had no experience in the area of mental retardation viewed slides of residential settings, five providing housing for people with mental retardation, and rated their "home-likeness" (1 = home-like, 5 = institutional). Of 55 two-way comparisons, the mean home-likeness ratings of 48 such pairs differed significantly from one another. A .98 log-linear correlation was found between number of residents in a given facility and institutional ratings. Of 26 features of living rooms studied in detail, furniture position, lighting type, and lighting flexibility were highly correlated with home-likeness, whereas building code-specific features and seating type were minimally related to home-likeness.
