Outline of Final Research Achievements

Three experiments were conducted to evaluate the psychological and physiological effects of white or off-white base colours of the house interior on elderly and young residents. Psychological measurements used were the semantic differential method and subjective appraisals concerning the relaxation and glare rating scales. Physiological measurements used were participants’ cerebral blood flow, high frequency/low frequency (HF/LF) ratio and heart rate.
As a result, it was shown psychologically and physiologically that the feeling of relaxation was caused by the warm coloured off-white interiors. On the other hand, it was also shown that the feeling of tense and glare were caused by the too white interiors.
