What Is the Perceived Environmental Restorative Potential of Informal Green Spaces? An Empirical Study Based on Visitor-Employed Photography

Informal green spaces (IGSs) play an essential role in enhancing urban well-being by offering restorative environments, yet the impact of visitor behaviors on perceived restorativeness (PR) remains underexplored. This study investigates how different spatio-temporal behaviors influence PR in IGS, providing urban planners with actionable insights to optimize these spaces for better user experiences. Using a visitor-employed photography (VEP) survey and post-visit PR assessments, K-means clustering was applied to identify distinct visitor behavior patterns. Correlation analysis further explored the relationships between these patterns and PR; the results reveal three unique clusters of visitor behaviors—fast, extensive exploration; moderate, focused exploration; and slow, thorough exploration—each showing distinct impacts on PR. Visitors who engage in rapid, broad exploration perceive larger, navigable spaces as more restorative, while those focusing on specific or in-depth exploration emphasize psychological aspects like escape and fascination. These behavioral patterns demonstrate varying strengths in their association with restorative experiences; This study underscores the importance of integrating spatio-temporal behavior data with PR assessments, highlighting how the physical and psychological features of IGS influence visitor experiences. These findings offer critical insights for designing and managing IGS to accommodate diverse user needs and promote urban well-being.

Research on the restorative effects and perception of privacy driven activities in Chinese classical gardens-Case studies of three Suzhou gardens.

The need for privacy, recognized as a fundamental psychological requirement, has garnered increasing attention as researchers explore the restorative effects of privacy driven activities (PDA). This study employs quantitative experiments and analyses to assess the restorative benefits of PDA within three classical Chinese gardens, demonstrating their superiority over conventional leisure activities in promoting emotional recovery, reducing stress, and restoring attention. The experiment quantifies the restorative effects of PDA versus standard leisure activities using a classic restorative scale and physiological indicators reflecting emotional relief. Regression analyses then identify five key factors influencing the occurrence of PDA, derived from preferred locations and behavioral tendencies observed in the three gardens. Further analyses reveal significant differences in the impacts of these five environmental feature dimensions on the evaluation indicators of "preference for privacy-oriented activities" and "restorative effects". Among these dimensions, "spatial scale and accessibility" has the greatest impact on the "preference for privacy-oriented environments", while "spatial atmosphere" and "activity facilities" have the most significant impact on "restorative effects". The findings suggest that behavioral activities mediate the relationship between environmental factors and restorative effects, highlighting the potential of PDA as a mediating variable for a comprehensive investigation into the pathways and mechanisms influencing restorative environments in research and design.

Creating restorative corridors - Perceptual and physiological feedback of children on the audiovisual environment in primary school corridors

The corridor space of the primary school campus is frequently used for recess and relaxation by the students, which brings stress and emotional recovery from the intense academic work. How to integrate natural restorative environment into the corridor has attracted academic and practical attention. Based on Kaplan's theory of Restorative Environment, this study combined subjective evaluation with physiological feedback to explore the primary school children's perception and evaluation of corridor space, and proposed the effects of different audio-visual indicators. Based on a questionnaire survey of children's activities and restoration in two schools, the paper found the association between perceived restoration and high interaction behavior in the corridor, including floriculture and interacting with hands-on devices. The richness of amenities and colors in the corridor space had the highest correlation with children's restorative ratings, followed by interface openness and sky visibility. Natural soundscapes also had a strong correlation with children's auditory restorability. Subsequent virtual audition experiments validated above findings, suggesting the benefits of increased greenery, sky and natural sounds in reducing children's stress.

Travel as a Tool for Trauma Recovery: A Mixed-Methods Analysis Integrating Quantitative and Qualitative Approaches

This study aims to explore how travel serves as a tool for trauma recovery, aiding individuals in coping with psychological trauma and promoting mental health. We adopted a pragmatic mixed-methods approach, conducting two complementary studies: qualitative interviews with individuals who have experienced trauma and a quantitative survey. The qualitative interviews reveal the mechanisms and key factors of travel in the trauma recovery process. Based on the interview data, we constructed a conceptual model that includes latent variables such as travel experience, emotional regulation, self-reflection, social support, and trauma recovery. This model was subsequently validated through a quantitative survey study using Partial Least Squares Structural Equation Modeling. The results indicate that travel significantly promotes trauma recovery by providing a restorative environment, facilitating emotional regulation, and enhancing social interaction. This study provides new insights into the role of travel in trauma recovery and offers practical guidance for mental health interventions.

Relationship Between Tourists' Perceived Restorative Environment and Wellness Tourism Destinations

ABSTRACTThis study aims to determine the importance of tourists' perceptions of wellness tourism destinations and their performance based on tourists' perceived restorative environments. An empirical analysis was conducted using sample data collected through a survey with 428 tourists who have experienced wellness tourism. According to the analysis results, there were differences in the level of tourists' perception of the restorative environment. Based on these differences, tourists were subdivided into “the high‐perception group,” “the medium‐perception group,” and “the low‐perception group.” A clear difference in the importance and performance of wellness destinations considered by tourists based on clusters was also found. This segmentation based on the restorative environment can be applied to the development of tourism resource tailored to tourist characteristics.

Restorative Potential Assessment of Public Open Space in Old Urban Communities in the Context of Aging—A Case Study of Dabeizhuang Community in Maanshan, China

Restorative environments have a positive impact on improving the physical and mental health of the elderly. In China, the proportion of elderly residents in aging urban communities is significantly higher than in newly constructed ones, making it essential to understand the restorative potential of public open spaces (POSs) in these settings to promote the development of aging-in-place models. To investigate this issue, we employed the Fuzzy Delphi Method (FDM) and the Analytic Hierarchy Process (AHP) to construct an evaluation system for the restorative potential of public open spaces. Subsequently, we assessed the restorative effects of POSs in the Dabeizhuang community using 320 residents’ questionnaires and the fuzzy comprehension evaluation method. The results indicate that the dimension of safety is the most critical factor in creating restorative environments. In contrast, the dimension of comfort is the primary reason affecting the current evaluation of the community’s restorative environment. By establishing a restorative environment evaluation system, this research will facilitate the creation of more restorative environments in urban areas, thereby promoting active and healthy aging among elderly residents.

Predicting and Optimizing Restorativeness in Campus Pedestrian Spaces based on Vision Using Machine Learning and Deep Learning

Restoring campus pedestrian spaces is vital for enhancing college students’ mental well-being. This study objectively and thoroughly proposed a reference for the optimization of restorative campus pedestrian spaces that are conducive to the mental health of students. Eye-tracking technology was employed to examine gaze behaviors in these landscapes, while a Semantic Difference questionnaire identified key environmental factors influencing the restorative state. Additionally, this study validated the use of virtual reality (VR) technology for this research domain. Building height difference (HDB), tree height (HT), shrub area (AS), ground hue (HG), and ground texture (TG) correlated significantly with the restorative state (ΔS). VR simulations with various environmental parameters were utilized to elucidate the impact of these five factors on ΔS. Subsequently, machine learning models were developed and assessed using a genetic algorithm to refine the optimal restorative design range of campus pedestrian spaces. The results of this study are intended to help improve students’ attentional recovery and to provide methods and references for students to create more restorative campus environments designed to improve their mental health and academic performance.

Effects of different audiovisual landscapes in bamboo forest space on physical and mental restorative potential of university students: based on eye-tracking experiments

With its unique audiovisual environment, bamboo forest spaces serve as natural sanctuaries for urban residents, offering significant restorative effects by reducing physical and mental stress and alleviating fatigue. This promotes the vigorous development of outdoor recreation activities. To further explore the restorative effects of bamboo forest space on people's audiovisual perceptual aspects. In this study, we conducted field research in the Southern Sichuan Bamboo Sea, collecting audiovisual materials from four types of bamboo forest spaces: pathway type, cultural type, ornamental type, and recreational. These spatial photographs were combined with three types of soundscapes (silent, background, and background + wind-blown bamboo sound). Eye tracking experiments were utilized to investigate the physical and mental restorative effects of these different audiovisual features on college students. The results showed that in the visual aspect, the visual restorative properties of recreational-type and ornamental-type bamboo spaces were better than those of pathway type and cultural-type spaces; in the auditory aspect, the sounds of wind-blown bamboo, flowing water, and chirping birds in the bamboo forest significantly enhanced the subjective restorative properties of the bamboo forest space, reducing the number of fixations and the average pupil diameter. In addition, this paper found that the soundscape guided people's visual attention, with the wind-blown bamboo sound increasing focus on natural elements, and the extensibility of the bamboo forest space was positively correlated with the number of fixations, while fascination was negatively correlated with the average saccade amplitude. These findings provide insights for the optimized design of audiovisual restorative environments in bamboo forest space in the future.

Exploring the impact of university green spaces on Students' perceived restoration and emotional states through audio-visual perception

A growing body of evidence suggests that university green space (UGS) can substantially enhance students' perceived restoration. This study employed virtual reality technology to assess the characteristics of audio-visual elements in three types of UGS, then utilized Peason correlation analysis and structural equation modeling (SEM) to explored environmental audio-visual perception, perceived restoration, and their associations with emotional state. Findings indicate that: (1) Within the same UGS type, the dominance of different audio-visual elements was relatively consistent across various locations. However, there were differences among different UGS types: artificial sounds were dominant in Commuter Green Spaces, while natural sounds were more prominent in Natural Green Spaces, and the perception trends for visual elements were similar to those of the sound sources. (2) Soundscape pleasantness was significantly positively correlated with three dimensions of perceived restoration and positive emotion, negatively correlated with negative emotion, and had similar findings to soundscape pleasantness in visual perception and soundscape eventfulness. (3) The SEM results showed that soundscape pleasantness and eventfulness could directly influence visual perception and positive emotion. In addition, our study also found a cascading mediating effect with visual perception and perceived restoration as core elements. These findings deepen our understanding of how audio-visual perceptions influence emotional restoration and well-being, potentially enhancing both student experiences and the quality of UGS. Furthermore, the findings underscore the complexities involved in perception assessment, influenced by variations in social backgrounds, cultural factors, and individual characteristics. This emphasizes the need for future research to consider these variables comprehensively, aiming to provide a deeper understanding of the specific physical attributes of restorative environments.

Multisensory nature exposure in the workplace: Exploring the restorative benefits of smell experiences

Previous research has extensively documented several benefits of interacting with nature. Biophilic design applications aimed at connecting the built environment back to nature have been shown to improve employee health, well-being, and productivity at workplaces. However, most research regarding restorative environments has prioritized the visual qualities of nature experiences, neglecting other sensory modalities. The significance of the sense of smell in the restoration process has been largely ignored. This research investigates the combined effects of multi-domain nature experiences within workplace contexts. Specifically, the restorative benefits of combined multisensory elements, including visual, olfactory, and auditory, and the relative contributions of each sensory cue to the restoration process were examined. A pretest-posttest experimental approach was employed to compare the restorative outcomes of workplaces under two conditions, one lacking natural elements vs another offering multi-domain experiences of nature. Thirty-two participants engaged in a multisensory virtual reality simulation replicating the environmental conditions of an actual workplace in Sydney, Australia. The results revealed that the multisensory biophilic workplace significantly improved cognitive performance, reduced stress levels, and enhanced mood states compared to the non-biophilic one. There was a statistically significant association between the sense of smell and restorative benefits. Although visual elements emerged as the primary means of creating restorative workplace environments, our results suggest that the sense of smell plays a significant role in the restoration process. This paper provides empirical evidence on the paramount importance of olfactory cues in nature-based experiences, contributing to the knowledge within the realms of biophilia and architectural discourse.

Urban green space preferences for various health-related psychological benefits of adolescent pupils, university students and adults

Previous research has shown that biophysical and social characteristics of urban green spaces (UGS) and individual factors may play a role in preferences for restorative environments. However, little is known about the trade-offs between (bio)physical and social characteristics of UGS on different health-related psychological benefits between different population groups. This exploratory study used an image-based discrete choice experiment, in which 298 adolescent pupils, 159 university students, and 142 adults were asked which urban green spaces they would prefer for general recovery, stress reduction, and concentration improvement. Each of the 128 green space scenarios depicted different attributes of varying levels of recreational infrastructure, numbers of trail users, distances between forest vegetation and trail, traffic noise, background scenery, both in winter and in summer. The results indicate that visitor numbers and traffic noise strongly influenced green space preferences for all study groups, but groups differed in terms of their preferences and trade-offs for the psychological benefits. The biophysical environment was less important for adolescent pupils, while recreational infrastructure was less important for the adults. There were group differences in stated preferences for general recovery, stress reduction, and concentration enhancement. Implications for urban green space planning are presented.

A Qualitative Study on University Students’ Restorative Experience of the Library Space Environment

Currently, university students are facing high levels of stress and negativity. Creating a campus learning environment that promotes students’ physical and mental health and well-being has become a key focus of current research. There is now a wealth of research proving that the natural attributes of learning spaces are highly restorative for university students, both physically and mentally. In order to comprehensively clarify the characteristics of the library spatial environment that has a restorative effect on university students, this paper conducted semi-structured interviews with 50 university students and thematically analyzed the data obtained from these interviews. Ultimately, we identified five key themes: (1) Being away: students believe that studying alone is a way to escape social pressures, immersing themselves in their studies helps them forget everything around them, and the view from the window creates a sense of detachment; (2) Extent: students perceive the design of the library space as rich and orderly; (3) Fascination: many elements of the library spatial environment appeal to them and make them feel energized. The overall atmosphere motivates them to engage more actively in their learning; (4) Compatibility: the library spatial environment provides a variety of facilities that meet their learning needs, along with various types of spaces catering for different behaviors; and (5) Biophilia: Many interviewees mentioned the benefits of natural environments and timber, as well as their preference for spaces with a sufficient sense of enclosure and the ability to observe others. The first four themes were found to be closely related to the Attention Restorative Theory during the course of the study, while the last theme was mentioned by most of the students. The results of this study prove that library spaces can be described as restorative environments in the same way as natural environments, with both physical and mental restorative effects. Furthermore, the results of this study can also provide certain ideas for the design and renovation of the internal spatial environment of university libraries.

The nose cooperates with the eyes: The independent and interactive effects of vision and olfaction on the perceived restorativeness of a Metasequoia walkway

In response to worldwide calls for promoting health and well-being, there is growing interest in creating restorative environments. Although restorative environments can be perceived by multiple sensory modalities, visual studies dominated the majority of restorative research, while olfaction is a frequently overlooked yet important sense. Grounded in Attention Restoration Theory (ART) and cross-modal interaction of olfaction and vision, this research seeks to investigate the independent and interactive effects of vision and olfaction on the perceived restorativeness of a Metasequoia walkway in urban green space. The visual stimulus was a 360-degree virtual reality (VR) tour in a 200-meter-long Metasequoia walkway, and the olfactory stimulus was Metasequoia essential oil extracted from the tree leaves. Based on a stress recovery experiment, 120 participants were randomly assigned to one of four groups: control, vision, olfaction, and combination. Psychological evaluations (semantic differential scale [SDS] and perceived restorativeness scale [PRS]) and physiological measurements (systolic blood pressure [SBP], diastolic blood pressure [DBP], heart rate [HR] and blood oxygen level [BOL]) were used as indicators of restorative effects. The findings reveal that a combination of visual and olfactory stimulation can contribute more to restorative effects compared to a single stimulus, in terms of both physiological and psychological indicators. This calls for a greater focus on the effects of vision and olfaction towards more sustainable landscape design and management.

Effects of natural sound on human stress recovery based on EEG techniques

Natural sounds are an essential part of a restorative environment. Although numerous studies have established the positive impact of natural sounds on human health and well-being, few have examined the differences between natural sounds on human stress recovery. This study examined the impact of natural sounds on stress recovery by comparing a silent environment (control group) with three experimental groups exposed to flowing water sound, birdsong, and wind sounds. The investigation entailed the assessment of subjective assessments and EEG signals from 30 subjects (12 males and 18 females). The subjective evaluations indicated that the PRS scores for the sounds of flowing water and birdsong were superior to those of the silent environment. The EEG results revealed that EEG-α activity was more pronounced in response to natural sounds than the silent environment, with birdsong evoking the most significant EEG-α activity. Wind sounds increased the mental stress of the subjects. Conversely, birdsong and flowing water sound were beneficial for alleviating mental stress. Additionally, the analysis of event-related potentials (ERP) demonstrated that natural sounds elicited higher P300 amplitudes in central and parietal lobe sensors and had little effect on the frontal region. The study also demonstrated the correlation between EEG and subjective stress evaluations, providing insights into stress reduction theories and offering practical suggestions for optimizing the acoustic environment in urban settings.

Place perception and restorative experience of recreationists in the natural environment of rural tourism

IntroductionIn contemporary society, people spend long periods under high stress, and tourism activities have gradually been internalized as a new means of stress release and self-recovery. Studies have found that the high-quality natural environment of rural tourism destinations has a higher restorative effect than other places, and the rural natural environment can provide psychological recovery to visitors on top of offering visual beauty and other experiences.MethodsThis paper starts with the relationship between rural place perception and restorative experience evaluation. Based on theories such as the restorative environments theory, we investigates whether rural natural environmental factors have a restorative effect on recreationists through collecting 300 questionnaires and using SPSS 26.0 structural equation modeling for analysis.ResultsThe study found that there is a positive correlation between rural natural perception, place dependence, and restorative experience, forming a positive feedback loop dynamic system. The analysis suggests that enhancing the perception of the rural natural environment and place attachment can improve the restorative experience of recreationists in rural settings.DiscussionThis research establishes a systematic research framework for the relationship between rural natural perception, place attachment, and restorative experience, to deeply understand the dynamic interaction between them. It reveals the relationship between rural natural perception and restorative experience, suggesting that enriching the perceptual elements in rural natural spaces can meet the diverse needs of recreationists, enhance the sense of dependence and identification with rural spaces, and thus promote the psychological well-being and restorative experience of recreationists. The study also finds that place dependence plays a mediating role between rural natural perception and restorative experience. Place attachment and place identity, as mediating variables, act as bridges and catalysts in the process of rural natural perception affecting restorative experience.

Combined Effects of the Visual–Acoustic Environment on Public Response in Urban Forests

Urban forests are increasingly recognized as vital components of urban ecosystems, offering a plethora of physiological and psychological benefits to residents. However, the existing research has often focused on single dimensions of either visual or auditory experiences, overlooking the combined impact of audio–visual environments on public health and well-being. This study addresses this gap by examining the effects of composite audio–visual settings within three distinct types of urban forests in Fuzhou, China: mountain, mountain–water, and waterfront forests. Through field surveys and quantitative analysis at 24 sample sites, we assessed visual landscape elements, soundscapes, physiological indicators (e.g., heart rate, skin conductance), and psychological responses (e.g., spiritual vitality, stress relief, emotional arousal, attention recovery) among 77 participants. Our findings reveal that different forest types exert varying influences on visitors’ physiology and psychology, with waterfront forests generally promoting relaxation and mountain–water forests inducing a higher degree of tension. Specific audio–visual elements, such as plant, water scenes, and natural sounds, positively affect psychological restoration, whereas urban noise is associated with increased physiological stress indicators. In conclusion, the integrated effects of audio–visual landscapes significantly shape the multisensory experiences of the public in urban forests, underscoring the importance of optimal design that incorporates natural elements to create restorative environments beneficial to the health and well-being of urban residents. These insights not only contribute to the scientific understanding of urban forest impact but also inform the design and management of urban green spaces for enhanced public health outcomes.

A Review of Attention Restoration Theory: Implications for Designing Restorative Environments

The promotion and development of healthy cities are vital for enhancing human habitats and fostering sustainable economic growth. Based on the core databases of Web of Science, PubMed, Google Scholar, and PsycINFO, and the knowledge graph software, this paper presents a quantitative analysis of the literature related to attention recovery abroad. It is found that in recent years, the research on attention recovery has developed rapidly, the number of related studies has been increasing, and the research content presents the characteristics of interdisciplinary integration. By further analyzing the characteristics of the research literature, research context, and knowledge basis, this paper summarizes the empirical research based on the existing quantitative analysis, reviews the research field based on the mechanism of attention recovery, and analyzes the development process and trend based on the research basis of attention recovery. Due to the change in the modern life style, human health problems are becoming more and more prominent. Attention restoration design provides a new research idea and method to balance the relationship between humans and the urban environment.

The effects of interaction with audiovisual elements on perceived restoration in urban parks in freezing weather

Urban green spaces, crucial for urban residents’ wellbeing, offer restorative benefits mainly through natural elements, as established in existing literature which were generally conducted in warm weather. Yet, cold weather modifies how both natural and anthropogenic elements appear and function, and hence their impacts on restorativeness may deviate. In cold weather, whether an urban green space would be overall restorative, and which type of elements would be more beneficial remains poorly understood. Here we present the results of a walk experience experiment with 20 participants on three typical landscape routes in a waterside park in a winter city. Participants' restorative experiences and their visual and auditory exposures were evaluated using the Restorative Experience Scale, eye tracker, and binaural acoustic measurement system. By comparing participants’ restorative experience and their visual and auditory exposure, we found that in the cold weather, natural elements vegetation and water surfaces, the appearances of which were subjective to major seasonal changes, ceased to promote restorativeness. Aesthetically pleasing landscape decorations instead promoted the restorativeness of the environment strongly (β = 0.286, p = 0.004). Additionally, soundscape appropriateness (β = 0.320, p = 0.002) and lower environmental loudness (for N5, β = −0.430, p = 0.000) were also strong positive influencers. These collectively explained 49.7 % of the overall restorative experience in a multiple linear regression model (adjusted R2 = 0.497). Our findings should guide the rational wellbeing-directed landscape design of restorative environments in cold regions to allow sustained restorativeness throughout the year.
