Harmony in Nature: Exploring the Multisensory Impact of Classical Gardens on Individuals' Well-Being

Objectives: Chinese classical gardens, designated as a vital world cultural heritage, embody a lasting legacy transcending generation. Despite the cultural importance of these gardens, a notable research gap exists in deciphering the nuanced emotional and physiological responses triggered by individual elements within classical garden landscapes. Our research question aims to uncover the specific emotional and physiological impacts of key garden elements-plants, architecture, waterscape, and rockery-on visitors, with a particular focus on the Humble Administrator's Garden. These elements serve as the primary subjects for video capture at four sites. Study Design: A within-subject design experiment was used. Methods: Videos were recorded at these sites, encompassing visual, auditory, and tactile elements. Ninety-five participants watched these videos in an indoor setting. While viewing, we measured participants' physiological responses, including heart rate variability, skin conductance, and skin temperature, will be monitored alongside subjective assessments obtained through self-reported questionnaires such as the Emotional Perception Scale and State-Trait Anxiety Scale. Results: Findings suggest that while all landscape types evoke positive emotions, natural elements exert a more profound influence. Additionally, the Large Rockery emerges as a focal point, indicating enhanced emotional relaxation through auditory and tactile stimuli, particularly among younger individuals. Conclusions: This research contributes to the broader understanding of how classical gardens impact human emotions and well-being, offering insights that can inform future landscape design and promote mental health in diverse cultural contexts.
