Abstract:

Residential interior space can have some significant impacts on inhabitant’s physical and mental health, and interior form is one of the main interior design parameters that has rarely been studied from the mental health perspective. Emotion is one of the mental health factors that is related to residential diseases and the built environment; therefore, this study investigated residential interior form from an emotional perspective in both fields of environmental psychology and neuroarchitecture. This study sought to fill the existing gaps in this field by considering personality traits, clustering of 3D forms and having natural movement in the experiments. The aim of this neuroarchitecture study was to clarify the effects of different forms on emotion by considering brain dynamics, in order to assess the interior form from the mental health perspective and determine the emotional impact of the forms on users.

In this basic research, data was obtained from reference documents, photos, questionnaires (virtual images and verbal) and physiological data. Through the use of quantitative method, this study sought to determine the relationship between interior form, emotion and brain dynamics. Totally, by using a correlational research method, this study was conducted in three phases. Data mining was used for the first phase while experimental and simulation methods in virtual reality were used for the second and third phases.

The results showed 25 formal clusters from the interior forms. The relationship between each formal cluster and descriptive feature, emotion and comfort by considering personality traits was evaluated and presented in different tables. The results demonstrated significant differences between curvature and rectangular forms in the activity of the ACC region in the brain in theta frequency. Also, different brain areas such as ACC, precentral gyrus, PCC and occipital lobe showed significant changes according to different room perspectives. This study added a new field in neuroarchitecture and the use of a new method and technologies, sheds a new light on architectural research.
