THE DEPTH OF PSYCHOSOCIAL CONSIDERATION VARIES WITH ARCHITECTURAL FUNCTION. THESE FACTORS INCREASE AS A BUILDING USAGE BECOMES MORE ANTHROPOPHILIC. SITUATIONS RELATING TO AMBIGUOUS DESIGN MUST BE ELIMINATED IN BUILDING DESIGN. PROBLEMS INVOLVING VISUAL PERCEPTION SUCH AS (1) GLASS DOORS, (2) APPARENT INSECURITY OF STRUCTURE, (3) AMBIGUOUS SYMBOLIC REPRESENTATIONS, AND (4) LACK OF EFFECTIVE CONTRASTS ARE CRITICAL. CONFUSING VISUAL SITUATIONS SUCH AS INDOOR-OUTDOOR RELATIONSHIP, TALL BUILDING INSECURITY, OR SPATIAL INCOHERENCE, AND LACK OF IDENTITY MUST ALSO BE CONTENDED WITH. THE CULTURALLY DEPENDENT CONCEPT OF PRIVACY DEMANDS CONSIDERATION IN (1) OFFICE RELATIONSHIPS AND APPARENT SEPARATION CHARACTERISTICS, (2) SANITARY FACILITIES, (3) DESIGN OF ACCESS PATTERNS, AND (4) DEFINITION OF SOCIAL RELATIONSHIPS. PROPER RECOGNITION OF SAFETY AND WELFARE FACTORS DEPENDS UPON THE DETERMINATION OF PERFORMANCE-ORIENTED STANDARDS. THIS ARTICLE IS A REPRINT FROM "BUILDING RESEARCH," JULY-AUGUST 1965.
