Pleistocene Hypothesis - Moving Savanna Perceptual Preference Hypothesis Beyond Savanna.

We provide an extension of the Savanna perceptual preference hypothesis ("Savanna Hypothesis"), supposing that interaction with landscapes offering survival advantage for human groups during evolution might have gradually evolved to permanent landscape preferences. This additional support is based on the palaeoenvironmental analysis of the spread of modern humans into Europe in the late Pleistocene and their living environments there. Our hypothesis is that the preference for park-like landscapes after African savannas experienced a kind of "refreshment" in the Pleistocene. Thus, preferences for certain types of natural settings and scenes may have a more continuous evolutionary history than previously thought. The extended Savanna Hypothesis termed "Pleistocene Hypothesis" might stimulate further work on this important topic linking human evolution and human environmental preferences.

Results from an 18 country cross-sectional study examining experiences of nature for people with common mental health disorders.

Exposure to natural environments is associated with a lower risk of common mental health disorders (CMDs), such as depression and anxiety, but we know little about nature-related motivations, practices and experiences of those already experiencing CMDs. We used data from an 18-country survey to explore these issues (n = 18,838), taking self-reported doctor-prescribed medication for depression and/or anxiety as an indicator of a CMD (n = 2698, 14%). Intrinsic motivation for visiting nature was high for all, though slightly lower for those with CMDs. Most individuals with a CMD reported visiting nature ≥ once a week. Although perceived social pressure to visit nature was associated with higher visit likelihood, it was also associated with lower intrinsic motivation, lower visit happiness and higher visit anxiety. Individuals with CMDs seem to be using nature for self-management, but 'green prescription' programmes need to be sensitive, and avoid undermining intrinsic motivation and nature-based experiences.

Evaluating the Reliability and Validity of the Children's Vitality-Relaxation Scale.

This study developed the Children's Vitality-Relaxation Scale (CVRS) by revising the adult version of the Restoration Outcome Scale (ROS). The CVRS was translated and culturally adapted into Korean, and its reliability and validity were evaluated in a cross-sectional, descriptive design study. Data collected from 181 elementary school students in grades 4‒6 were used to test the validity and reliability of the CVRS. Exploratory factor analysis, Pearson's correlation, known-groups comparison, and Cronbach's alpha were used for analysis. The factor analysis indicated a two-factor structure, and all factor loadings were above 0.40. The CVRS was a seven-point Likert scale consisting of eight items, which were classified as "vitality" (four items) and "relaxation" (four items). The external construct validity with the PANAS, PSS, and SRI was acceptable. In the known-groups comparison, the CVRS score was significantly higher for boys than for girls, and the CVRS score for high-income students was higher than low-income students. The Cronbach's α for the scale was 0.84 and ranged from 0.72-0.87 for the subscales. Results showed that the CVRS is a valid and reliable scale with acceptable psychometric characteristics in Korean children. The scale can be used to measure children's affect in various settings.

Environmental Strategies of Affect Regulation and Their Associations With Subjective Well-Being.

Environmental strategies of affect regulation refer to the use of natural and urban socio-physical settings in the service of regulation. We investigated the perceived use and efficacy of environmental strategies for regulation of general affect and sadness, considering them in relation to other affect regulation strategies and to subjective well-being. Participants from Australia, Finland, Germany, Great Britain, Italy, India, the Netherlands, Portugal, and Sweden (N = 507) evaluated the frequency of use and perceived efficacy of affect regulation strategies using a modified version of the Measure of Affect Regulation Styles (MARS). The internet survey also included the Satisfaction with Life Scale (SWLS), emotional well-being items from the RAND 36-Item Health Survey, and a single-item measure of perceived general health. Environmental regulation formed a separate factor of affect regulation in the exploratory structural equation models (ESEM). Although no relations of environmental strategies with emotional well-being were found, both the perceived frequency of use and efficacy of environmental strategies were positively related to perceived health. Moreover, the perceived efficacy of environmental strategies was positively related to life satisfaction in regulating sadness. The results encourage more explicit treatment of environmental strategies in research on affect regulation.

The relationship between perceived health and physical activity indoors, outdoors in built environments, and outdoors in nature.

BACKGROUND: A body of evidence shows that both physical activity and exposure to nature are connected to improved general and mental health. Experimental studies have consistently found short term positive effects of physical activity in nature compared with built environments. This study explores whether these benefits are also evident in everyday life, perceived over repeated contact with nature. The topic is important from the perspectives of city planning, individual well-being, and public health. METHODS: National survey data (n = 2,070) from Finland was analysed using structural regression analyses. Perceived general health, emotional well-being, and sleep quality were regressed on the weekly frequency of physical activity indoors, outdoors in built environments, and in nature. Socioeconomic factors and other plausible confounders were controlled for. RESULTS: Emotional well-being showed the most consistent positive connection to physical activity in nature, whereas general health was positively associated with physical activity in both built and natural outdoor settings. Better sleep quality was weakly connected to frequent physical activity in nature, but the connection was outweighed by other factors. CONCLUSION: The results indicate that nature provides an added value to the known benefits of physical activity. Repeated exercise in nature is, in particular, connected to better emotional well-being.

Favorite green, waterside and urban environments, restorative experiences and perceived health in Finland.

The study investigated restorative experiences in relation to respondents' everyday favorite places and analysed the associations between the use of favorite places, restorative experiences, their determinants and aspects of self-rated health. A simple random sample of 1273 inhabitants, aged between 15 and 75 years, of two major cities in Finland (Helsinki and Tampere) completed a postal questionnaire. A subsample of the answers from inhabitants with a self-reported distance from home to a favorite place of 15 km or less (n = 1089) was analysed. Restorative experiences in favorite exercise and activity outdoor areas, waterside environments and extensively managed natural settings (mainly urban woodlands) were stronger than in favorite places in built urban settings or green spaces in urban settings (mostly parks). The results revealed a link between the need for restoration (worries and stress), the use of environmental self-regulation strategies (favorite places) and restorative outcomes. The more worries about money and work (during the last month) a person had, the more stressed a person had felt during the last year, the less energetic s/he had felt, the lower was the number of visits to the favorite place (during the last 6 months) and the lower the typical level of restorative experiences. Inconsistently, the direct path suggested that the more worries about money and work, the higher the typical level of restorative experiences. The findings increase knowledge of health-enhancing environments and have implications for stress and work recovery research.

Determinants of restorative experiences in everyday favorite places.

The study was based on the answers to a mailed questionnaire of a simple random sample of respondents from two cities (Helsinki, Tampere) in Finland. Ten determinants of restorative experiences in favorite places (

What is a nice smile like that doing in a place like this? Automatic affective responses to environments influence the recognition of facial expressions.

An affective priming paradigm with pictures of environmental scenes and facial expressions as primes and targets, respectively, was employed in order to investigate the role of natural (e.g., vegetation) and built elements (e.g., buildings) in eliciting rapid affective responses. In Experiment 1, images of environmental scenes were digitally manipulated to make continua of priming pictures with a gradual increase of natural elements (and a decrease of built elements). The primes were followed by presentations of facial expressions of happiness and disgust as to-be-recognized target stimuli. The recognition times of happy faces decreased and the recognition times of disgusted faces increased as the quantity of natural/built material present in the primes increased/decreased. The physical changes also influenced the evaluated restorativeness and affective valence of the primes. In Experiment 2, the primes used in Experiment 1 were manipulated in such a way that they were void of any recognizable natural or built elements but contained either similar colours or similar shapes as primes in Experiment 1. This time the results showed no effect of priming. These results were interpreted to give support for a view that the priming effect by environmental pictures is due to the primes representing environmental scenes and not due to the presence of certain low-level colour or shape information in the primes. In all, the present results provide evidence that perception of environmental scenes elicits automatic affective responses and influences recognition of facial expressions.

Perceived health is associated with visiting natural favourite places in the vicinity.

Visiting favourite natural settings may serve as a resource for regulating negative feelings and coping with perceived stress. The authors investigated the association between perceived health, the selection and experiential qualities of favourite places in four residential areas; 211 respondents (average age 40 years) responded to the questionnaire. Respondents with a certain amount of health complaints, such as headaches, chest or stomach pains, and faintness or dizziness, were more likely to select natural favourite places than those with few complaints. Respondents with health complaints benefited more in emotional terms from their visits to the favourite place although they did not visit their places more frequently than others. The change toward positive feelings was associated in particular with natural favourite places and relaxing in them. The results give impetus to research on the self-regulation of mood and neighbourhood context in health.
