The Relationship between Density and Crowding

It was hypothesized that architectural features of rooms, other than room size, would affect the perceived size of the rooms as well as perceived crowdedness. This hypothesis was examined with reference to usable space, level of illumination, and expansiveness of view from room windows. It was found that these features did affect the judged size and crowdedness. It was also found that perceived size and perceived crowdedness are independent.
