Architecture 101 : 6

6. We move through negative spaces and dwell in positive spaces.

The shapes and qualities of architectural spaces greatly influence human experience and behavior, for we in habit the spaces of our built environment and not the solid walls, roofs, and columns that shape it. Positive spaces are almost always preferred by people for lingering and social interaction. Negative spaces tend to promote movement rather than dwelling in place.
