Environmental preference and restoration: (How) are they related?

Does the widely documented tendency to prefer natural over built environments owe to the perception of greater restorative potential in natural environments? In the present experimental study we tested the mediating role of restoration in environmental preferences. Participants viewed a frightening movie, and then were shown a video of either a natural or a built environment. We used two examples of each type of environment. Participants’ mood ratings were assessed before and after they viewed the frightening movie, and again after viewing the environmental video. Participants also rated the beauty of the environment shown (to indicate preference) and performed a test of concentration after viewing the environmental video. The results indicate that participants perceived the natural environments as more beautiful than the built environments. In addition, viewing natural environments elicited greater improvement in mood and marginally better concentration than viewing built environments. Mediational analyses revealed that affective restoration accounted for a substantial proportion of the preference for the natural over the built environments. Together, these results help substantiate the adaptive function of people's environmental preferences.     

AUTOBIOGRAPHICAL MEMORY AND AFFECT UNDER CONDITIONS OF REDUCED ENVIRONMENTAL STIMULATION

Two experiments were conducted to study the effects of 1-hour sessions of flotation REST (restricted environmental stimulation technique) on mood and autobiographical memory. In Study 1, flotation was shown to produce a significant decrease in self-rated anxiety and arousal. Subjects in Study 2, who experienced similar changes in mood and arousal, reported that autobiographical memories retrieved in REST were more pleasant and intense, and had been more frequently recalled in the past, than those recollected in a control environment.     

Beyond savanna: An evolutionary and environmental psychology approach to behavioral effects of nature scenery in green advertising

Evolutionary psychology has been proposed as an analytic framework for the behavioral effects of landscapes displayed in advertising. In this study, an evolutionary and environmental psychology approach is used to analyze affective reactions to advertising depicting specific natural environments or urban scenes, both prominent ingredients of contemporary advertising imagery. The experimental field study exposed 750 participants at random to one advert of a set of 13 experimental green energy advertisements, each displaying a different biome. Six basic emotional responses (pleasure, arousal, happiness, freedom, safety, and interest) as well as attitude toward the ad and brand attitude were assessed subsequently. Anova and structural equation analysis were used for data analysis. Results of the study confirm the leading opinion on generalized more positive behavioral effects toward visual stimuli representing nature scenes with biospheric contents as opposed to pictures of urban environments or desert settings. In line with earlier empirical research, further findings do not support the hypothesis on an innate preference for savanna landscapes in adults but confirm preferences for images of lush green landscapes with water and familiar biomes. Overall results give significant support to the application of environmental and evolutionary psychology to advertising.     

Tracking restoration in natural and urban field settings

We compared psychophysiological stress recovery and directed attention restoration in natural and urban field settings using repeated measures of ambulatory blood pressure, emotion, and attention collected from 112 randomly assigned young adults. To vary restoration needs, we had half of the subjects begin the environmental treatment directly after driving to the field site. The other half completed attentionally demanding tasks just before the treatment. After the drive or the tasks, sitting in a room with tree views promoted more rapid decline in diastolic blood pressure than sitting in a viewless room. Subsequently walking in a nature reserve initially fostered blood pressure change that indicated greater stress reduction than afforded by walking in the urban surroundings. Performance on an attentional test improved slightly from the pretest to the midpoint of the walk in the nature reserve, while it declined in the urban setting. This opened a performance gap that persisted after the walk. Positive affect increased and anger decreased in the nature reserve by the end of the walk; the opposite pattern emerged in the urban environment. The task manipulation affected emotional self-reports. We discuss implications of the results for theories about restorative environments and environmental health promotion measures.     

Is elevation encoded in cognitive maps?

Two experiments examined whether differences in elevation of the terrain are encoded in cognitive maps of outdoor environments. In Experiment 1, two groups of subjects who had travelled a varying number of times between a set of locations made direct estimates in metres of the differences in elevation between the locations. The results showed that subjects in both groups had knowledge of elevation but those for whom the terrain was less familiar tended to exaggerate the differences. In Experiment 2, decision times were measured of responses to the question whether one location is below or above another one. Neither for subjects who were more, nor for subjects who were less familiar with the terrain, did the decision times vary with the distances between the locations, thus failing to support the hypothesis that differences in elevation are retrieved by a process of ‘mental travel’.     

Effects of Place Identity,Place Dependence,and Experience-Use History on Perceptions of Recreation Impacts in a Natural Setting

It is generally accepted that recreation use in natural environments results in some degree of negative social and environmental impact. Environmental managers are tasked with mitigating the impact while providing beneficial recreation opportunities. Research on the factors that influence visitors' perceptions of environmental and social conditions is necessary to inform sound environmental management of protected natural areas. This study examines the effect of prior experience with the setting and two dimensions of place attachment (i.e., place identity and place dependence) on visitors' perceptions of three types of recreation impacts (i.e., depreciative behavior, environmental impacts, and recreation conflict). Principal components analysis, confirmatory factor analysis, and structural equation modeling were used to test the study hypotheses using data collected from 351 visitors through on-site questionnaires (response rate of 93 percent). The results show that prior experience exhibited a moderate and significant direct positive effect on place identity, place dependence, and visitors' perceptions of recreation impacts. Contrary to study hypotheses and prior research, neither place dependence nor place identity exhibited a significant effect on the dependent variables. The results show that prior experience causes visitors to be more sensitive to depreciative behaviors, environmental impacts, and recreation conflict. These findings raise concerns over potential visitor displacement and deterioration of site conditions. Implications for resource managers are discussed, which include education, modifying visitor use patterns, and site design strategies.     

Managing Dive Tourism for the Sustainable Use of Coral Reefs: Validating Diver Perceptions of Attractive Site Features

It has been argued that strategies to manage natural areas important for tourism and recreation should integrate an understanding of tourist preferences for specific natural features. However, the accuracy of tourist recalled perceptions of environmental attributes, which are usually derived from post hoc surveys and used to establish management priorities, is currently unmeasured. We tested the validity of the relationship between tourist-stated preferences and actual condition of coral reefs around the Caribbean island of Bonaire. Using standardized questionnaires, we asked 200 divers to select their most and least favorite dive sites and the attributes that contributed to that selection. We also carried out ecological surveys at 76 of the 81 dives sites around the island to assess the actual conditions of the attributes indicated as important for site selection. Fish- and coral-related attributes were key features affecting dive enjoyment. In general, divers appeared to be able to perceive differences between sites in the true condition of biological attributes such as fish species richness, total number of fish schools, live coral cover, coral species richness, and reef structural complexity, although men and women divers differed in their ability to perceive/recall some of the attributes. Perceived differences in environmental attributes, such as surface conditions, underwater current, and the likelihood of encountering rare fish and sea turtles, were not empirically validated. The fact that divers perceive correctly differences in the condition of some of the key biological attributes that affect dive enjoyment reinforces the need to maintain overall reef condition at satisfactory levels. However, variation in accuracy of perceptions owing to demographic factors and attribute type suggests the need for caution when using public perceptions to develop environmental management strategies, particularly for coral reefs.     

Strategies for combating urban flooding in a developing nation: A case study from Ondo,Nigeria

Summary Flooding has become an inherent problem in most urban centres close to the Nigerian coast. In the last decade it has extended to large settlements in the interior of the country where rainfall is more sporadic. This study has revealed that various socio-cultural activities have promoted flooding in many of these Nigerian urban environments. These activities are characterised by stream or river channel encroachment and abuse, increased paved surfaces and poor solid waste disposal techniques, due to a high level of illiteracy, a low degree of community awareness, poor environmental education, ineffective town planning laws and poor environmental management. Govenment, at various levels, needs to address these issues.His special field of interest is in natural resource management, focusing on the implications of environmental degradation and sustainable development.     

Spatial representations,a wayfinding perspective

Wayfinding, conceptualized in terms of spatial problem solving, subsumes decision making, decision executing and information processing. Spatial representations are a product of the latter. In this paper, rather than relying on the practice of inferring wayfinding characteristics from studies done on spatial representations, I shall inverse the argument and explore characteristics of spatial representations, in particular the notion of accuracy, from a wayfinding perspective.Wayfinding decisions are hierarchically structured into plans which not only helps to memorize routes in behavioral terms, but helps to organize and record environmental information in the form of sequential, route-type representations. Survey-type representations also rely on memory supportive structures but these are directly inferred from the spatial configuration of a setting.Both types of representations induce metric and topological distortions, but these are not necessarily detrimental to wayfinding. Travelling on routes, experienced on previous occasions, requires an act of recognizing but not recalling environmental features. Spatial representations based on recall are only required when planning new routes, and even then, they do not need to be recalled in great detail. It is argued that the question of accuracy in spatial representations ought to be posed in respect to practical use rather than cartographic parameters.     

Identification and quantification of the hydrological impacts of imperviousness in urban catchments: a review

Urbanisation produces numerous changes in the natural environments it replaces. The impacts include habitat fragmentation and changes to both the quality and quantity of the stormwater runoff, and result in changes to hydrological systems. This review integrates research in relatively diverse areas to examine how the impacts of urban imperviousness on hydrological systems can be quantified and modelled. It examines the nature of reported impacts of urbanisation on hydrological systems over four decades, including the effects of changes in imperviousness within catchments, and some inconsistencies in studies of the impacts of urbanisation. The distribution of imperviousness within urban areas is important in understanding the impacts of urbanisation and quantification requires detailed characterisation of urban areas. As a result most mapping of urban areas uses remote sensing techniques and this review examines a range of techniques using medium and high resolution imagery, including spectral unmixing. The third section examines the ways in which scientists and hydrological and environmental engineers model and quantify water flows in urban areas, the nature of hydrological models and methods for their calibration. The final section examines additional factors which influence the impact of impervious surfaces and some uncertainties that exist in current knowledge.     

Preconceptions of students about the natural urban environment in a small Spanish city

Summary The preconceptions of secondary students from a small Spanish city, mainly about natural aspects, have been studied. The main characteristic of their conceptions about the urban natural environment was that it was always linked to negative aspects and was generally seen as something essentially problematic. Moreover, it seems that their knowledge of smaller living beings, of wild animals, plants and fungi, was worse than for other urban living beings. The analysis of these alternative conceptions has led the authors to propose some recommendations for curricular design and development for schools in urban environments.Dr Mercedes Suárez is an educationalist and Professor of Curriculum in the Faculty of Humanities in the University.

Walking in “wild” and “tended” urban forests: The impact on psychological well-being

The positive effect of natural compared to urban environment on human restoration and well-being has been proved in various studies. To go one step further in analyzing the influence of physical environments, we question if this positive effect is consistent in different natural conditions namely wild and tended urban forests. In an experimental field setting, participants were randomly assigned to either a walk through wild or tended forests for 30 min. Multidimensional scales in a pre-post-treatment-setting measured well-being. Results indicate a stronger change in “positive affect” and “negative affect” in the tended forest condition. Well-being factors “activation” and “arousal” changed after solitary walks, too. However, there were no differences between the treatment conditions, indicating a stronger influence of physical activity than the forest condition wild and tended on these well-being factors. Perceived attractiveness of the natural area did not effect the change in well-being, thus questioning the close relation between perceived attractiveness and the effect on well-being suggested in prior research. Furthermore, more and less fatigued persons did not profit differently concerning well-being changes. The results give important advice to design natural areas serving restoration and public health, especially for people living in urban environments.

Experimental evidence for a dual pathway model analysis of coping with the climate crisis

Two experiments examined the psychological power of fear and group efficacy beliefs to increase environmental action intentions against the climate crisis. Extending a dual pathway model of coping with collective disadvantage, results showed evidence for emotion-focused approach coping: Environmental action intentions were increased by individuals' manipulated fear of the negative future consequences of the climate crisis (Experiments 1–2). Additionally, results showed evidence for problem-focused approach coping: Individuals' measured (Experiment 1) and manipulated group efficacy beliefs (Experiment 2) increased environmental action intentions. The results thus suggest that the dual pathway model can be successfully applied to a psychological analysis of emotion- and problem-focused approach coping with the climate crisis. We discuss the theoretical and practical implications of these results.     

The Effects of Urbanization on Net Primary Productivity in Southeastern China

Net primary productivity (NPP) is one of the major ecosystem products on which human societies rely heavily. However, rapid urban sprawl and its associated dense population and economic conditions have generated great pressure on natural resources, food security, and environments. It is valuable to understand how urban expansion and associated demographic and economic conditions affect ecosystem functions. This research conducted a case study in Southeastern China to examine the impacts of urban expansion and demographic and economic conditions on NPP. The data sources used in research include human settlement developed through a combination of MODIS, DMSP-OLS and Landsat ETM+ images, the annual NPP from MODIS, and the population and gross domestic product (GDP) from the 2000 census data. Multiple regression analysis and nonlinear regression analysis were used to examine the relationships of NPP with settlement, population and GDP. This research indicates that settlement, population and GDP have strongly negative correlation with NPP in Southeastern China, but the outcomes were nonlinear when population or GDP reached certain thresholds.     

Where to recover from attentional fatigue: An expectancy-value analysis of environmental preference

Preferences for natural and urban environments can be framed in terms of (1) beliefs about the likelihood of psychological restoration during a walk in each type of environment and (2) the evaluation of restoration given differing restoration needs. We conducted an experiment to test hypotheses about restoration as a basis for environmental preferences. Imagining themselves as attentionally fatigued or fully refreshed, participants (N=101) evaluated recovery, reflection, and social stimulation outcomes. Next, they viewed slides simulating a walk through a forest or an urban center, then rated the likelihood of recovery, reflection, and social stimulation outcomes following such a walk. This procedure was repeated with the second environment. Preference for the forest over the city was twice as strong given attentional fatigue. The greater likelihood of restoration in the natural environment in conjunction with more positive evaluation of recovery when fatigued appears to explain this pattern. The results have implications for environmental preference conceptualizations and our understanding of the relationship between preference and restoration.     

What can abnormal environments tell us about normal people? Polar stations as natural psychology laboratories

The psychological effects of unusual environments reveal different aspects of behaviour from those seen in more customary situations. Such environments provide natural laboratories in which many questions of psychological interest, varying with the specific environment, may be studied. This paper uses isolated polar stations to illustrate this point. In such settings, the usual parameters that control a variety of psychological processes are drastically changed, and confounding variables are stripped away. Consequently, the environment offers unique perspectives on environmental perception and cognition; adaptation to and use of the environment; environmental bonding; social interaction; and coping with environmental challenge.     

“Coal is in our food,coal is in our blood”: everyday environmental injustices of rural community gardening in Central Appalachia

ABSTRACT

Central Appalachia's historical dependence on natural resource extraction industries has contributed to a long history of under- and uneven development, including trends of persistent poverty, cycles of unemployment, weakened local governance, environmental degradation, and severe social inequalities relative to the rest of the nation. Though these trends have been well documented at structural and community-levels, scholarship is more limited in assessing how the conditions of natural resource dependency may shape the everyday experiences of those who live in such regions and how those everyday experiences may illuminate challenges for future development. Employing an embedded case study design, this study examines how everyday environmental injustices may be experienced via community gardening activities, a sustainable development-oriented activity celebrated in urban locations but largely unexplored in rural environments. Drawing upon in-depth interviews with 43 gardening programme coordinators and participants, the findings demonstrate that everyday environmental injustices are experienced across four distinct, yet overlapping and mutually reinforcing, dimensions: natural, built, human health, and socioeconomic environments. These factors in turn constrain programme participation and beneficial programme outcomes, particularly for more disadvantaged households that are affected by chronic illness, geographic isolation, and environmental hazards. Although the interviewees viewed many of these challenges as further justification for pursuing grassroots initiatives like community gardening programmes, these constraints also interacted in a way that limited the success of these locally-oriented sustainable development efforts, particularly for individuals who are the most socially, economically, and environmentally marginalised.
