Perception of Comfort of Interior Architecture Based on the 4 Personality Characters of Hippocrates Galenus

The perception of comfort in interior architecture is closely related to individual personality traits, which can influence design preferences and sensory experiences. This study explores the relationship between Hippocrates-Galen personality types (melancholic, phlegmatic, choleric, and sanguine) with the perception of comfort in interior architecture through a multisensory approach. The research method uses neurological response measurements using EEG (Electroencephalography) with 20 participants aged 20–44 years. The variables tested include visual comfort, texture, aroma, and acoustics, with the main indicators being performance metric data on relaxation and stress levels.The results showed that personality type significantly influenced the perception of comfort. Melancholic individuals tend to be more sensitive to disproportionate room dimensions, rough textures, and high noise but feel comfortable with calming scents such as Lavender or Rose. Phlegmatics show a consistent level of comfort in all sensory stimuli, reflecting their stable and tolerant character. Sanguine is more responsive to cheerful visual factors and fresh scents such as Citrus but is sensitive to high noise. Choleric individuals, although more tolerant of noise and rough textures, prioritize elements that support control and efficiency.This study provides insight into how a personality-based design approach can enhance personal comfort in interior architecture. These results encourage designers to consider the specific sensory needs of each personality in creating spaces that support individual well-being and productivity. Further research is recommended to expand multisensory parameters and explore other external factors that influence comfort perception.
