People’s conceptual environmental appraisals of urban space in daylight and electric light

Urban spaces should be resilient, inclusive and safe for all residents including children, elderly and vulnerable groups. This implies that urban planning, management and design should provide public spaces that support human needs of active mobility, social interaction and psychological restoration across seasonal and diurnal variation in natural light. Environmental psychology postulates that an understanding of how people experience or appraise an environment is a critical component in the relationship between urban design and human behaviour. In this conceptual paper we propose and discuss overarching (visual) impressions of the environment (environmental appraisals) that could be utilized to deepen the understanding of how people experience urban green spaces under different lighting conditions. In a certain setting, people respond to specific components of the environment; such perceived molecular environmental qualities make up the overall impression of the setting, and shape critical human-environment transactions fundamental to human well-being. The perceived stimuli are considered to act together to form the perceptual basis for higher order, molar aspects, so called conceptual environmental appraisals. We introduce Küller’s human-environment interaction model and Brunswik’s lens model to describe conceptual environmental appraisals. Recognising urban forests as important settings for physical active mobility, social interaction, and psychological restoration, we outline the theoretical underpinnings of three conceptual environmental appraisals: prospect – refuge pertaining to the perceived safety of the environment, environmental preferences, and the perceived restorative potential of the environment. The appraisals have been shown to be relevant in studies on electric lighting in urban space, and possible to assess by means of observer-based assessments also among children, elderly and vulnerable groups. Assessment outcomes may inform discussions on conflicting goals for sustainable development with regard to people’s health and well-being, energy use, light pollution and the welfare of other species in urban planning, management and design.

Wildlife and public perceptions of opportunities for psychological restoration in local natural settings

Abstract Wildlife might be important to psychologically restorative values and disvalues of nature, as interactions with wildlife could trigger both positive and negative feelings. Research on positive experiences of human–wildlife interactions has largely involved participants who voluntarily sought out wildlife experiences or it has addressed encounters with non‐threatening animals in urban green spaces. Less is known about the opportunities for psychological restoration in landscapes shared with mammals that are perceived to pose a threat to human activities and health. This study provides a nuanced understanding of the role of wildlife in public perceptions of the restorative potential and experience of psychological restoration in local natural settings. Twenty‐eight participants (15 women, 13 men, 18–75 years) took part in focus group interviews subject to a reflexive thematic analysis. As an analytical framework, we used a theoretical model for how people appraise the relevance, implications, coping potential and norm congruence of human–wildlife interactions and how such appraisals may support or hinder the restoration experienced in local natural settings. Relevance appraisals revealed shifts in consideration of the presence of wildlife from an integrated part of the natural scenery (background) to a distinct figure (foreground). Implication appraisals revealed that wildlife encounters would hinder the experienced psychological restoration if the animal was appraised as dangerous, disgusting, causing a nuisance or destructive. Wildlife encounters would promote restoration if the animal displayed attractive traits, features or fascinating behaviour or movements, and if it opened engaging interaction situations. Coping strategies perceived as feasible to deal with negative implications of wildlife involved avoidance of the local natural setting, preparatory behaviour displayed before a visit and precautionary behaviour displayed during the visit. Important public health effects might be gained if wildlife policy and management explicitly consider what animals mean to the perceived restorative potential of local natural settings.

Wasting the restorative potential: Influences of plastic and biowaste on psychological restoration after real, virtual, and imagined walks

Nature experiences benefit human wellbeing by, for example, increasing subjective restoration and positive affect while reducing negative affect. However, natural environments are threatened by several crises, including pollution. In three preregistered studies, one correlational and two experimental, we investigated the relationship between (plastic) litter and restoration after a walk. In Study 1, participants did a self-selected restorative walk and afterwards reported observed litter. In two experimental studies, we manipulated the presence of plastic waste, biowaste (which served as an active control condition with human-sourced but degradable litter), and no waste in a virtual (i.e., video; Study 2) and an imagined (Study 3) forest walk. In all studies, we assessed subjective restoration, current affect and connectedness to nature, attractiveness and preference of scenery, as well as plastic-related problem awareness, intentions, and policy support. Results showed that litter, especially from plastic, is associated with harmful changes in subjective restoration, affect, and the perception of the scenery. Connectedness to nature, as well as plastic-related problem awareness, intentions, and policy support were not affected by the presence of plastic. Thus, plastic pollution influences human wellbeing negatively, but did not affect factors important to reduce consumption. Therefore, more research on tackling the plastic crisis is needed.

The environmental experience during daylight and dark conditions: a conceptual model for pedestrians and cyclists / La experiencia ambiental en condiciones de luz diurna y oscuridad: Un modelo conceptual para peatones y ciclistas

Walking and cycling are considered sustainable transport modes, promoted as a means to reduce car traffic. In the scientific literature, they have mostly been investigated separately, but should be considered jointly to enable a modal shift. Both daytime and dark conditions need to be studied, to improve understanding of how environmental features are affected by temporal variation. A conceptual model is introduced to advance understanding of the significance of different environmental factors for walking/cycling, and serves as the basis for the design of an empirical study. A between-subject design was used, comparing two pedestrian/cycle paths located in two mid-sized Swedish cities during daytime and after dark. Pedestrians ( n = 90) and cyclists ( n = 74) responded to questionnaires assessing environmental parameters hypothesized to be of importance for walking and cycling. Three-factor ANOVAs indicated differences between the two locations (perceived stimuli), between pedestrians and cyclists (environmental appraisal, affective response, behavioural intention) and between daytime and dark conditions (visual accessibility, restorative potential). The conceptual model helps identify the importance of various environmental features.

Effects of Audio–Visual Interaction on Physio-Psychological Recovery of Older Adults in Residential Public Space

It is now well established that everyday interaction with nature has a restorative potential on the elderly population’s health and well-being. However, empirical evidence on the restorative effects of neighborhood greenspace is still lacking, and scant attention has been given to the cross-effect of the visual–audio experience. The present study examined the restorative effects of audio–visual interactions on older adults in typical residential public spaces in Chinese cities. A pretest–post-test design was used to measure changes in participants’ physiological responses, mood states, and mental restoration. Participants (mean age = 68.88 years) were asked to experience six simulated audio–visual conditions (3 scenes × 2 sounds) of residential public space. The results showed that: (1) A green scene combined with nature sounds showed the most restorative effect on the elderly participants’ psycho-physiological health. (2) Viewing green scenes facilitated the most psycho-physiological recovery for the elderly, followed by viewing the activity scene. (3) Compared to the traffic noise, adding nature sounds could promote many more benefits in HR recovery, positive mood promotion, and perceived restorative effects, and the advantage of nature sounds over traffic noise was mainly demonstrated in the green scene. (4) Visual scenes demonstrated a greater impact on the elderly participants’ psycho-physiological recovery than the sounds. Our findings suggested the necessity of providing residential nature and activity spaces, encompassing both sound and vision, to promote healthy aging in Chinese residential contexts.

Wildlife and the restorative potential of natural settings

How does the likelihood of encountering wildlife affect residents’ expectations about psychological restoration when visiting a local natural setting, and their choices among settings for future recreation? Do urban and rural residents differ in such expectations and choices? We addressed these questions in a web-based experiment with 223 adult residents randomly sampled from urban and rural areas in each of three regions in Sweden. Residents in all six areas can encounter fear-irrelevant wildlife (roe deer, squirrel) near the home, but the presence of fear-relevant wildlife (wolf, wild boar) differs across the areas. The respondents read scenarios concerning encounters with each of these four animals during recreational visits to a nearby natural setting. The scenarios varied in how frequently the person could expect to encounter each animal across visits (never, sometimes, often). For all 12 scenarios, respondents answered questions about anticipated experiences and restoration outcomes, and the effect of encounter likelihood on future recreational setting choices. Across all areas, with all outcomes, increased likelihood of encounters with the wolves and wild boar detracted from anticipated restorative potential, whereas increased likelihood of encounters with roe deer and squirrel enhanced anticipated restorative potential. A similar pattern showed in recreational setting choices. A domination wildlife value orientation moderated the effects of encounter likelihood for wolf and wild boar, whereas a mutualistic orientation moderated the effects of encounter likelihood for squirrel and roe deer. Our results suggest that wildlife management and public health practice could work together not only to address the fears of residents, but also to enhance the restorative quality of local natural settings by protecting wildlife.

The Interplay Between Rehabilitation and Media Communication: A Case Study on San Quentin News

This research paper delves into the intricate interplay between media communication and personal rehabilitation, with a particular focus on the unique case study of the San Quentin News, which is a media organization established and operated by incarcerated individuals within San Quentin State Prison. The overarching objective of this study is to elucidate the positive roles played by media communication in fostering personal recovery in both spiritual and social dimensions, while also assessing the transformative influence of media communication. To undertake this research, a methodological approach rooted in quantitative research has been employed. The study independently crafted a questionnaire, which was subsequently disseminated within the precincts of San Quentin prison. This questionnaire was administered to individuals who had previously been engaged in contributing to the San Quentin News. In pursuit of investigating the impact of media on individual recovery, this academic study concludes that media plays a predominantly positive role in the recovery process across various psychological and societal dimensions. This assertion finds support in the case study presented within this paper, highlighting the substantial restorative potential of media, especially within the context of the correctional system.

Visual properties and perceived restorativeness in green offices: a photographic evaluation of office environments with various degrees of greening.

Office environments play a critical role in employee wellbeing and productivity. While the benefits of incorporating nature into workspaces have been recognized, the specific visual characteristics that contribute to restorativeness remain unclear. This study investigates how visual characteristics of office environments, specifically the presence of greenery and color complexity, are associated with perceived restorativeness. In Study 1, we developed a scale based on Attention Restoration Theory to measure the restorative characteristics of office environments, consisting of three subscales: Being Away, Fascination, and Extent. In Study 2, we used this scale to examine the correlation between the restorative characteristics of offices and the visual properties of office photographs. The results showed that the square root of the percentage of green area, the color fractal dimension, and the brightness fractal predicted perceived restorativeness. Notably, the color fractal dimension often showed a stronger effect than the amount of greenery per se. These findings suggest that both the presence of greenery and the overall complexity of color transitions in office spaces contribute to their restorative potential. Our study provides insights for designing more restorative office environments, emphasizing the importance of not only increasing greenery but also mimicking natural color patterns. The predictive model developed provides a practical tool for estimating the restorative potential of office designs. Although there are limitations such as the use of photographic assessments and the inability to fully explain the Extent component of restorativeness, this study contributes to our understanding of how to create more psychologically supportive work environments.

Age-associated functional healing of musculoskeletal trauma through regenerative engineering and rehabilitation.

Traumatic musculoskeletal injuries that lead to volumetric muscle loss (VML) are challenged by irreparable soft tissue damage, impaired regenerative ability, and reduced muscle function. Regenerative rehabilitation strategies involving the pairing of engineered therapeutics with exercise have guided considerable advances in the functional repair of skeletal muscle following VML. However, few studies evaluate the efficacy of regenerative rehabilitation across the lifespan. In the current study, young and aged mice are treated with an engineered muscle, consisting of nanofibrillar-aligned collagen laden with myogenic cells, in combination with voluntary running activity following a VML injury. Overall, young mice perform at higher running volumes and intensities compared to aged mice but exhibit similar volumes relative to age-matched baselines. Additionally, young mice are highly responsive to the dual treatment showing enhanced force production (p < 0.001), muscle mass (p < 0.05), and vascular density (p < 0.01) compared to age-matched controls. Aged mice display upregulation of circulating inflammatory cytokines and show no significant regenerative response to treatment, suggesting a diminished efficacy of regenerative rehabilitation in aged populations. These findings highlight the restorative potential of regenerative engineering and rehabilitation for the treatment of traumatic musculoskeletal injuries in young populations and the complimentary need for age-specific interventions and studies to serve broader patient demographics.

Applying 3D spatial metrics for landscape planning: Creating and measuring landscape scenarios by a point cloud-based approach

The current planning and design process predominantly relies on experts' experiences or preferences, which is beneficial and straightforward but can be subjective and time-consuming. Although there are some quantitative assessment tools available to aid decision-makers in understanding the perceived quality of landscape scenarios, how to integrate them into the design thinking process to improve landscape design is challenging. This study presents a 3D digital model integrating the quantitative representation of visual quality into the design thinking process to improve urban landscapes' restorative potential. The model consists of generating landscape scenarios in a 3D environment, converting them into point clouds and voxelising them, quantitatively assessing the restorative potential, and interactively modifying landscape designs. To demonstrate the feasibility and effectiveness of the model, we have applied it to improve the restorative potential of a park in Singapore. The results show that the model provides a clear assessment of landscape scenarios and identifies specific areas needing improvement. The significance of this study lies in an innovative approach to generating and assessing the landscape scenario, ultimately enhancing the overall quality of landscapes during the digital planning and design process.

Does restorativeness support liveliness on commercial streets?

ABSTRACT The role of restorativeness in attracting and retaining people on commercial streets has been under-researched. To examine this topic, this convergent parallel mixed methods study was conducted on four commercial streets in Brazil. It included a quantitative evaluation of correlations between a set of microscale aspects of commercial streets and liveliness, and a qualitative thematic analysis of users’ experiences informed by the Attention Restoration Theory. The results showed restorativeness as one pathway linking microscale aspects of commercial streets to liveliness. The perceived restorative potential of microscale aspects of commercial streets should be considered when adopting fine-grained approaches to enhance their liveliness.

Acoustic environment and its restorative potential in small urban green spaces

Small urban green spaces (SUGS) in dense city areas have been widely demonstrated to have restorative benefits to surrounding residents. However, residents' usage and experience of SUGS were indicated to be adversely influenced by adjacent traffic noise, whilst natural sounds inside could provide restorative soundscape resources. Thus, this study investigated the acoustic quality and its restorative potential in 12 SUGS in Qingdao via field measurements and questionnaire surveys. The results show that: (1) The noise level of SUGS largely ranged in 50-60 dBA, with dominant road traffic noise. Three perceptual soundscape dimensions were identified: appreciation, diversity and dynamics. (2) Scenic SUGS featured more natural sounds, lower noise levels, and more appreciation; residential SUGS featured more human sounds and worse soundscape evaluation; and business SUGS featured higher noise levels. (3) The acoustic environments in scenic SUGS showed much more restorative potential than residential and business ones, and the restorative potential of SUGS was highly influenced by sound levels (LAeq, L10, and L90), sound sources (traffic noise and natural sounds), and soundscape qualities (appreciation and diversity). The findings were expected to provide references for the sustainable planning and design of small urban green spaces in dense cities.

White Spaces Unveiled: Investigating the Restorative Potential of Environmentally Perceived Characteristics in Urban Parks during Winter

Creating attractive urban green spaces in severely cold and harsh climates is significant for promoting peoples’ health and perceived restoration. However, there is little evidence regarding the urban green spaces in wintery and cold climates and its restorative benefits. This study utilized a pixel grid approach to quantify winter landscape characteristics and a self-reporting method to assess the restorative benefits of audiovisual interactions. The results show the following: (1) Different types of roads in urban parks have significant differences in their level of restorativeness, and the restorativeness benefits of the primary path in winter parks are the strongest. (2) The presence of snowy elements in winter landscapes can enhance park users’ potential to experience restorative characteristics in relation to “being away”. Moreover, there exists a noteworthy positive correlation between deciduous trees and their restoration benefits. (3) People’s perceptions of the tranquility of the soundscape and the duration of environmental exposure are critical mediators in the impact of the restorative path effect. (4) Compared with women, men have a higher restorative level in both the landscape and soundscape. This elucidates the restorative role of white space landscapes and soundscapes in public psychological perception when proposing appropriate forest-based healthcare strategies. It also provides theoretical guidance and optimization schemes for the overall planning, health planning, and design of white spaces shaped by cold urban green spaces.

The acute psychological effects of screen time and the restorative potential of nature immersion amongst adolescents: A randomised pre-post pilot study

Excessive screen time can deplete the cognitive resources required for effective emotion regulation, such as sustained attention and inhibitory control. Contrastingly, time spent in natural environments encourages attention restoration and stress reduction. Therefore, time in natural environments may be important for buffering the psychological consequences of screen time. A randomised pre-post pilot study was undertaken to investigate the acute psychological effects of screen time in adolescents, and to explore the restorative potential of nature immersion. Eighty-seven adolescents (52% female, mean age = 15.5 years) participated in the study. Participants completed measures of mood, sustained attention capacity (Sustained Attention to Response Task), and inhibitory control (Stop-Signal Task) at three time-points: (1) at baseline, (2) after a 30-minute period of screen time, and (3) after a 20-minute period of rest. Participants were randomised to either an indoor setting or an outdoor environment (Botanic Gardens) for the rest period. Linear mixed modelling was used to examine the effect of time and resting condition on the outcome variables. A lack of change in baseline mood, sustained attention capacity, and inhibitory control was observed following the brief screen time period, which limited the ability to test the relative benefit of the outdoor vs indoor environment. The study demonstrated the feasibility of a novel and ecologically valid paradigm to test this relationship in school students, but future studies should look to apply the recommendations provided regarding altering the attentional demands of the screen time activity used. The potential for natural environments to benefit student wellbeing and performance remains an important area of continued research.

The Restorative Potential of Green Cultural Heritage: Exploring Cultural Ecosystem Services’ Impact on Stress Reduction and Attention Restoration

Green cultural heritage is an important form of natural space in cities. Only a few studies have conducted restorative studies in a historical environment as most have focused on natural environments. Moreover, few studies on cultural ecosystem services (CESs) have addressed cultural heritage. Based on an onsite questionnaire distributed to green cultural heritage users (N = 64) in Hamarikyu Garden, this paper explores the value of CESs in a green cultural heritage site and the relationship between cultural ecosystem values and perceived attention restoration/stress reduction. A multiple linear regression analysis and simple linear regression analyses were used to examine the data. The results showed that (1) the cultural ecosystem values of the green cultural heritage site were all rated highly except for the sense of place; (2) spending time in green cultural heritage provided respondents significant perceived attention restoration and stress reduction; (3) aesthetics and cultural heritage significantly affected perceived stress reduction, while attention restoration showed a significant positive correlation with aesthetic value and sense of place; and (4) the more visitors perceived the value of CESs, the more significant the perceived stress reduction and attention recovery were. This study indicates that CESs represent a useful tool for measuring the environmental characteristics of green cultural heritage sites and can predict perceived psychological recovery in green cultural heritage sites. Our findings enhance our knowledge about restorative environmental attributes through objective descriptions of potential health-promoting qualities and can be utilized as inspiration for designing restorative environments in green cultural heritage sites.

Effects of forest spatial types, element compositions and forest stands on restorative potential and aesthetic preference

IntroductionAs global urbanization intensifies, the physical and mental stressors of modern life have led to the growing prevalence of suboptimal health conditions. Spending time in a forest benefits human health and well-being. In this context, based on the forest spatial types (forest interior and forest edge spaces), landscape elements (architecture, water and roads) and forest stands (coniferous, broadleaf and bamboo forests), this study investigated the effects of different forest spatial landscape characteristics on the restorative potential for college students, aesthetic preference and eye movement behavior (total fixation duration and fixation count).MethodsIn this study, a total of 60 subjects were exposed to 42 photographs depicting typical forest landscapes acquired through field studies. The Short-version Revised Restoration and Preference Scale and eye-tracking technology, were employed to study the recovery efficiency and visual attraction of forest spatial of different forest spatial types, element compositions and forest stands.Results(1) The restorative potential and aesthetic preference score of forest edge spaces were significantly higher than those of forest interior spaces. (2) The restorative potential of bamboo forests was significantly higher than those of coniferous and broadleaf forests. (3) In terms of forest interior space, the restorative potential of “forest + 1 element” composition and “forest + 2 elements” composition was significantly higher than that of pure forest, and the restorative potential of interior space of bamboo forest was significantly higher than those of coniferous and broadleaf forests. (4) In terms of forest edge space, the restorative potential of “forest + 2 elements” composition was significantly higher than that of pure forest, and the restorative potential of pure forests was significantly higher than that of the “forest + 1 element” composition. (5) The restorative potential of forest spatial landscape characteristics positively correlated with aesthetic preference and negatively correlated with total fixation duration and fixation count. These results can provide a reference for future forest landscape research, construction and management.

Representing the landscape visual quality of residential green spaces in Singapore with 3D spatial metrics

Visual quality relates to people’s views, feelings about visiting landscapes, and restorative potential, which is crucial in planning urban spaces. This study has investigated the visual quality, particularly in its connection to restorative potential, of Singapore’s residential green spaces (RGSs) that are easily accessible and frequently visited by residents. We deployed a laser scanner to document 152 RGSs in high-density public housing estates and represented their landscape visual quality (LVQ) with previously developed 3D spatial metrics. The spatial metrics correlated to the Perceived Restorative Scale (PRS) of 1500 participants from an online survey were employed for cluster analysis to identify RGSs’ main features. The results concluded five main RGS clusters in Singapore: “High naturalness and low visual scale”, “Low naturalness and coherence”, “High visual scale and low coherence”, “High coherence and low visual scale”, and “Medium-high visual and low complexity”. A set of practical recommendations based on the weaknesses of each cluster were also provided to support their LVQ improvement. The significance of the study lies in the point cloud-based approach to document and characterise RGSs’ LVQ with 3D spatial metrics and paves a typological way to facilitate RGSs planning.

Grounding the Restorative Effect of the Environment in Tertiary Qualities: An Integration of Embodied and Phenomenological Perspectives.

This paper proposes an integration of embodied and phenomenological perspectives to understand the restorative capacity of natural environments. It emphasizes the role of embodied simulation mechanisms in evoking positive affects and cognitive functioning. Perceptual symbols play a crucial role in generating the restorative potential in environments, highlighting the significance of the encounter between the embodied individual and the environment. This study reviews Stress Reduction Theory (SRT) and Attention Restoration Theory (ART), finding commonalities in perceptual fluency and connectedness to nature. It also explores a potential model based on physiognomic perception, where the environment's pervasive qualities elicit an affective response. Restorativeness arises from a direct encounter between the environment's phenomenal structure and the embodied perceptual processes of individuals. Overall, this integrative approach sheds light on the intrinsic affective value of environmental elements and their influence on human well-being.

Using solicited research diaries to assess the restorative potential of exposure to inland blue space across time

Inland blue spaces, or freshwater environments, have been shown to provide people with positive mental health and wellbeing outcomes. Most inland blue space research focusing on wellbeing outcomes has so far been cross-sectional, utilising questionnaires and interviews. Therefore, there is significant uncertainty regarding the potential for inland waterways to benefit human populations over longer-term time scales. Across a sixteen-month data collection period, this study recruited four distinct sample groups to complete diaries for periods of three-months, focusing on inland blue space experiences in Scotland. The aim of the study was to use solicited diary methods to establish whether restorative exposure outcomes gained from visiting blue spaces may vary across time. Results from the diary data show that visiting freshwater areas consistently led to positive restorative outcomes, with minimal variation in restorative outcomes observed across time. Participants recorded three principal categories of blue space experiences; routine visits, getting fresh air; and day trips, with each visit type providing a range of restorative benefits. The findings highlight the potential for inland blue spaces to act as versatile public health resources and the need to consider long-term strategies to ensure these environments benefit populations across time.

Analysis of Landscape Character Assessment and Cultural Ecosystem Services Evaluation Frameworks for Peri-Urban Landscape Planning: A Case Study of Harku Municipality, Estonia

This study combined landscape character assessment (LCA) and cultural ecosystem services (CES) frameworks to evaluate human well-being in the peri-urban area of Harku Municipality, Estonia. Using geospatial data combined with expert opinions, the study investigated the interplay between landscape character types and environmental/contact types through the LCA method. In total, 21 distinct landscape types comprising 47 separate areas were identified, with CES values determined for each. Restorative, social, and cognitive values were associated with each landscape character type. The findings demonstrated the higher restorative potential of blue and green elements (water bodies, forests) with low settlement density and minimal agriculture. High-density settlements with good road access demonstrated significant social values, while mixed forests and wetlands tended to be associated with higher cognitive values. Coastal zones with semi-dense settlements and mixed forests earned favourable ratings, whereas industrial/agricultural landscapes were rated lowest for all values. These findings offer valuable insights into the complex dynamics of urban–rural interactions, resilience, and the impact of urbanisation on CES. They may inform future landscape management strategies, urban planning decisions, and policy considerations. Additionally, this study highlights the need for further research to explore the long-term trends and potential changes in CES in evolving peri-urban environments.
