Correlating stress reduction and eye movement patterns in a world famous Kyoto Japanese garden

Abstract

AbstractVisual stimuli have been repeatedly shown to elicit significant non-visual responses. In a continuing effort to explore the unique effects of viewing a Japanese garden on the physiological and psychological metrics of stress, we gained access to the world famous Murin-an garden in Kyoto, Japan. This well-maintained observation garden was designed to be viewed while seated at a single vantage point to maximize the impact of the visual scene. As a control, we used a public garden on the campus of Kyoto University that was designed in a similar style. Sixteen college age students were asked to view both gardens while we monitored their pulse rates and tracked their eye movements. We used the POMS questionnaire to determine the effect of the garden viewing on the mood of the participants. We found that the Murin-an garden was more effective in decreasing pulse rate and improving mood than the University garden. The eye tracking data showed that during their Murin-an viewing the participants gaze ranged far more broadly across the visual field both the X-Y plane and in depth, and the speed with which the eyes moved from point-to-point was greater. Taken together, our data suggest that no one element in the garden was dominant in eliciting the changes in heart rate and mood. Rather, it was the breadth and rapidity of the shifts in gaze that drove the effects, a conclusion with implications for other interventions aimed stress reduction.SignificanceViews of nature and natural phenomena have a well-recognized calming effect on humans that has recognized therapeutic value in both medical and psychological settings. Our work explores the source of this effect by having participants view Murin-an, a world-famous Japanese style garden. Using both psychological and physiological measures, we confirm and extend earlier findings showing that a well constructed garden can effectively lower heart rate and improve mood within minutes. We also find, by analogy with eye movement desensitization and reprograming (EMDR), that it is participants’ rapidly shifting gaze rather than a single specific visual object is the most likely source of the calming effect.
