In this essay I want to investigate the dynamic curved line and form. Research by Vartanian and others indicate that curvilinear forms in interior residential architectural settings are perceived as less stressful (Vartanian, e.a, 2013). I want to study these and other effects curvilinear shape has on human beings. How do we perceive rectangular shape and curvilinear shape. What is the difference between the two. Is there a preference? My research will be interdisciplinary, combining research in neuroscience, environmental behavior and design, psychology and theories in (organic) architecture.
