A Dose of Nature:Two three-level meta-analyses of the beneficial effects of exposure to nature on children's self-regulation

There is growing evidence that exposure to nature, as opposed to a built environment, is associated with better health. Specifically in children, more exposure to nature seems to be associated with better cognitive, affective, and behavioral self-regulation. Because studies are scattered over different scientific disciplines, it is difficult to create a coherent overview of empirical findings. We therefore conducted two meta-analyses on the effect of exposure to nature on self-regulation of schoolchildren (Mage = 7.84 years; SD = 2.46). Our 3-level meta-analyses showed small, but significant positive overall associations of nature with self-regulation in both correlational (15 studies, r = .10; p < .001) and (quasi-) experimental (16 studies, d = .15; p < .01) studies. Moderation analyses revealed no differential associations based on most sample or study characteristics. However, in correlational studies the type of instrument used to measure exposure to nature (index score of nature vs. parent-reported exposure) significantly moderated the association between nature and self-regulation. Stronger associations were found when exposure to nature was assessed via parent-reports than via an index such as by a normalized difference vegetation index (NDVI). Our findings suggest that nature may be a promising tool in stimulating children's self-regulation, and possibly preventing child psychopathology. However, our overview also shows that we are in need of more rigorous experimental studies, using theoretically based conceptualizations of nature, and validated measures of nature and its putative outcomes

Types and characteristics of urban and peri-urban blue spaces having an impact on human mental health and wellbeing: a systematic review

Urbanization is increasingly putting pressures on biodiversity, ecosystems and ecosystem services. Evidence indicates that green and blue spaces can support the mental health of urban residents. Policy makers, city planners, other decision makers, healthcare professionals, and land managers now face a major challenge to maintain and enhance natural areas and characteristics. Knowing which types and characteristics of blue and green space are beneficial for mental health is necessary to inform planning and management decisions. EKLIPSE received a request from the Ministry in charge of the Environment of France (MTES) to review: “Which types of urban and peri-urban green and blue spaces, and which characteristics of such spaces, have a significant impact on human mental health and wellbeing?”. After a preliminary scoping, a decision was made to perform two systematic reviews assessing the specific types and characteristics of blue space (review 1) and green space (review 2) on mental health and wellbeing. The systematic searches were supported and conducted by an experienced team of librarians, made possible by the financial support of the WHO. This report presents the systematic review for blue space (Review 1)

Green space in urban and peri-urban areas and mental health: which green space types and characteristics are most beneficial?

Urban green space plays an important role in the mental and physical health of urbanites, as well as of people working in or visiting urban areas (WHO Regional Office for Europe, 2016). But green space can be very diverse in its typology, including for instance urban forests, parks, playgrounds, allotments and urban farming locations. These green space types can also differ greatly in their defining characteristics; for instance, parks can differ in scenic beauty, vegetative composition or openness. Globally, continuing urbanization, as well as climate change, is increasingly putting pressure on the existence of green spaces within urban areas (e.g. Dallimer et al., 2011; Richards & Belcher, 2020). The scarcity of urban green space and the desire to create liveable cities requires in-depth knowledge on how different green space types and characteristics influence mental health, to facilitate well-informed design and planning choices

Blue space in urban and peri-urban areas and mental health: which blue space types and characteristics are most beneficial?

There is an increasing awareness that besides green spaces, blue spaces can also positively influence mental as well as physical health (see for example, Völker & Kistemann, 2011; Gascon et al., 2017). Blue spaces are: “outdoor environments – either natural or manmade – that prominently feature water and are accessible to humans either proximally (being in, on or near water) or distally/virtually (being able to see, hear or otherwise sense water)” (Grellier et al., 2017, p. 3). Examples include coasts, lakes, ponds and pond systems, wadis systems, artificial buffer basins and water courses. Together with green spaces they form the green-blue infrastructure. Therefore, a second systematic review focused on effects of blue spaces on mental health

Personal Informatics, Self-Insight, and Behavior Change: A Critical Review of Current Literature

Personal Informatics (PI) systems allow users to collect and review personally relevant information. The purpose commonly envisioned for these systems is that they provide users with actionable, data-driven self-insight to help them change their behavioral patterns for the better. Here, we review relevant theory as well as empirical evidence for this ‘Self-Improvement Hypothesis’. From a corpus of 6568 only 24 studies met the selection criteria of being a peer-reviewed empirical study reporting on actionable, data-driven insights from PI data, using a ‘clean’ PI system with no other intervention techniques (e.g. additional coaching) on a non-clinical population. First results are promising—many of the selected articles report users gaining actionable insights—but we do note a number of methodological issues that make these results difficult to interpret. We conclude that more work is needed to investigate the Self-Improvement Hypothesis and provide a set of recommendations for future work

Unconscious Persuasion by Ambient Persuasive Technology: Evidence for the Effectivity of Subliminal Feedback

Abstract. In this paper we explore a fundamental characteristic of Ambient Persuasive Technology: Can it persuade the user without receiving the user‘s conscious attention? In a task consisting of 90 trials, participants had to indicate which of three household appliances uses the lowest average amount of energy. After each choice, participants in the supraliminal feedback condition received feedback about the correctness of their choice through presentation of a smiling or a sad face for 150 ms. Participants in the subliminal feedback condition received identical feedback, but the faces were presented only for 25 ms, which prohibited conscious perception of these stimuli. The final third of the participants received no feedback. In the next task, participants rated the energy consumption of all presented appliances. Results indicated that supraliminal feedback and subliminal feedback both led to more correct energy consumption ratings as compared to receiving no feedback. Implications are discussed.. 1

Stopping the train of thought:A pilot study using an Ecological Momentary Intervention with twice-daily exposure to natural versus urban scenes to lower stress and rumination

\u3cp\u3eBackground: Stress, and specifically perseverative cognition, is considered to have considerable detrimental effects on mental and physical health. Interventions that can offer temporary stress relief could, therefore, bring considerable health benefits. Previous research has pointed to stress-reducing effects of exposure to nature after acute stressors, but has not yet investigated effects in the realm of everyday life. The present pilot study explores whether an ecological momentary intervention using exposure to natural images could be effective in lowering stress and improve mood. Methods: Fifteen participants (12 females) scoring above threshold on stress, depression, or anxiety completed two study periods of 6 days. They watched an urban (control) or natural slideshow twice daily. Using Ecological Momentary Assessment, effects on mood, and stress-related complaints were measured in everyday life. Results: Compliance to the study protocol was high, especially in the first week, with slightly more videos watched in the morning than in the evening. We found indications of improvements in mood, self-reported worrying (but not stress levels), and heart rate. Conclusions: The results suggest that twice-daily exposure to restorative visual content could be a viable Ecological Momentary Intervention, with the potential to reduce self-reported worry, lower autonomic activity, and increase positive affect.\u3c/p\u3
