Title: Impacts of nature imagery on people in severely nature-deprived environments
An estimated 5.3 million Americans live or work in nature-deprived venues such as prisons, homeless shelters, and mental hospitals. Such removal from nature can result in an “extinction of experience” that can further lead to disinterest or disaffection toward natural settings, or even biophobia (fear of the natural environment). People who infrequently – or never – spend time in nature will be deprived of the numerous physical and emotional benefits that contact with nature affords. We report on the effects of vicarious nature experiences (nature videos) provided to maximum-security prison inmates for one year, and compared their emotions and behaviors to inmates who were not offered such videos. Inmates who watched nature videos reported feeling significantly calmer, less irritable, and more empathetic, and committed 26% fewer violent infractions as compared to those who did not watch the videos. Prison staff corroborated these findings. This research reinforces the value of nature exposure as a powerful tool not only for corrections administrators, but also for urban planners and policy makers, to promote socially desirable behaviors.  more » « less

  1. Islands have often been used to exile political prisoners, migrants, criminals, mentally ill individuals, and others deemed unworthy. Yet the remoteness that made islands ideal prison sites is today exploited to develop nature-based ecotourism (NBET). Given the ‘prison to paradise’ phenomenon is previously undocumented in the literature, this paper explores three descriptive cases in the Global South: Ecuador (Galápagos Islands), Panamá (Coiba Island), and Colombia (Gorgona Island). This analysis identifies how the timelines of prison activities and the manifestations of tourism are influenced by contextual factors that determine whether carceral heritage is being preserved or overwritten in each context. The paper also highlights further opportunities to elaborate on this nascent theory and emphasise specific roles for archaeologists in that future research agenda. This work will appeal to scholars interested in dark heritage, prison tourism, island studies, and protected area managers involved with heritage preservation around former prison sites.

  2. Visual discomfort is related to the statistical regularity of visual images. The contribution of luminance contrast to visual discomfort is well understood and can be framed in terms of a theory of efficient coding of natural stimuli, and linked to metabolic demand. While color is important in our interaction with nature, the effect of color on visual discomfort has received less attention. In this study, we build on the established association between visual discomfort and differences in chromaticity across space. We average the local differences in chromaticity in an image and show that this average is a good predictor of visual discomfort from the image. It accounts for part of the variance left unexplained by variations in luminance. We show that the local chromaticity difference in uncomfortable stimuli is high compared to that typical in natural scenes, except in particular infrequent conditions such as the arrangement of colorful fruits against foliage. Overall, our study discloses a new link between visual ecology and discomfort whereby discomfort arises when adaptive perceptual mechanisms are overstimulated by specific classes of stimuli rarely found in nature.

  3. Worked examples are an educational tool widely used in introductory computer science classes, primarily for programming and code-tracing concepts. Prior research supports the use of worked examples as a scaffolding mechanism to help students build a solid foundation before tackling problems on their own. Whether breaking down the intricacies of code or explaining abstract theoretical concepts, worked examples offer a structured approach that nurtures a deeper understanding during self-study. This study explores how peer-created worked examples, shown through detailed step-by-step videos, aid student learning in an intermediate-level computer science course, namely computer systems. Our results suggest that worked-example videos are a useful study aid for intermediate computer science courses, such as computer systems. Students who watched the worked-example videos found them to be very helpful, and ranked them as the top study aid for succeeding on quizzes. Additionally, students with access to worked-example videos performed moderately better on quizzes compared to students without worked-example videos. Our results and experiences also suggest that worked-example videos are beneficial to the students who created them as well as their peers who use them.

  4. Videos that are shot using commodity hardware such as phones and surveillance cameras record various metadata such as time and location. We encounter suchgeospatial videoson a daily basis and such videos have been growing in volume significantly. Yet, we do not have data management systems that allow users to interact with such data effectively. In this paper, we describe Spatialyze, a new framework for end-to-end querying of geospatial videos. Spatialyze comes with a domain-specific language where users can construct geospatial video analytic workflows using a 3-step, declarative,build-filter-observeparadigm. Internally, Spatialyze leverages the declarative nature of such workflows, the temporal-spatial metadata stored with videos, and physical behavior of real-world objects to optimize the execution of workflows. Our results using real-world videos and workflows show that Spatialyze can reduce execution time by up to 5.3×, while maintaining up to 97.1% accuracy compared to unoptimized execution.

  5. Many people have the intuition that interacting with natural environments benefits their psychological health. But what has research actually demonstrated about the benefits of nature experience and the potential mechanisms underlying those benefits? This article describes empirical research on the cognitive benefits of interacting with natural environments and several theories that have been proposed to explain these effects. We also propose future directions that may be useful in exploring the extent of nature’s effects on cognitive performance and some potential mediating factors. Specifically, exposure to a variety of natural stimuli (vs. urban stimuli) consistently improves working memory performance. One potential mechanism for this is the perception of low-level features of natural environments, such as edge density in the visual domain. Although low-level features have been shown to carry semantic information and influence behavior, additional studies are needed to indicate whether perceiving these features in isolation is necessary or sufficient for obtaining the cognitive benefits of interacting with nature.
