The purpose of this study was to evaluate psychological and social factors as they relate to shelter habitability. A simulated shelter was constructed which provided for continuous auditory and visual monitoring of shelter occupants' reactions. Following a series of four short-duration pilot tests, a series of four experimental groups inhabited the shelter. Each experimental group consisted of thirty subjects and contained men, women and children.
