This study is a continuation of a previous study done in a virtual environment; now, we want to show that the results extent to a real-world environment

We report the findings of two studies investigating the relationship between perceived realism and a physically accurate approximation of reality in a virtual reality experience in which the user has been scaled by a factor of ten. Study 1 investigated perception of physics when scaled-down by a factor of ten, whereas Study 2 focused on enlargement by a similar amount. Studies were carried out as within-subjects experiments in which a total of 84 subjects performed simple interaction tasks with objects under two different physics simulation conditions. In thetrue physicscondition, the objects, when dropped and thrown, behaved accurately according to the physics that would be c...

As more people move into urban environments, the negative consequences of reduced connection with nature are becoming more apparent. One promising way to reverse this trend is by reconnecting humans with the natural world. Natural environments have been shown to exert beneficial influences on mental health; however, to effectively develop therapeutic interventions, there is a strong need to understand the mechanisms of action by which natural environments support positive mental health outcomes. This thesis investigated potential mechanisms of action for therapeutic nature exposure as well as the preliminary efficacy of nature exposure therapy in virtual reality. Research subjects completed a survey measure assessing previous visits to nature and self-reported mental health symptoms. They subsequently c...

Roger Ulrich proposed the Stress Reduction Theory, which stated that exposure to natural environments can ameliorate the negative effects of stress by improving positive emotions and eliciting beneficial physiological changes; however, the mechanism by which this occurs is not fully understood. One possible explanation could be nature’s ability to help humans become aware of their emotions as they are experiencing them and subsequently develop the ability to control their reactions to negative events and stressors as they are happening, thus reducing the negative impact on their mood as a result. Specifically, mindfulness has been found to provide an explanatory link between connectedness to nature and levels of depression, as well as to moderate the relationship between the perception of stressful life events and levels of positive well-being. However, empirical research on the association between mindfulness and nature is lacking and further exploration is merited. Thus, this project investigated natural environment exposure in virtual reality and the ability to be mindful during this exposure. Results demonstrate that mindfulness during the virtual nature treatment helped increase the resulting change in positive affect due to the exposure and helped explain the statistically insignificant effect on negative affect. These findings suggest that mindfulness plays a moderating role on the beneficial impacts of natural environment exposure in virtual reality on human health and well-being.

We are developing a research project that will explore the extent to which exposure to natural environments in virtual reality (VR) can improve human health and wellbeing compared with exposure to real natural environments. Recordings of psychological (e.g., personality, mood) and physiological (e.g., skin response, cortisol level) measurements will be taken while subjects view and hear natural environment scenes in a virtual reality head mounted display or in the ‘actual’ natural environments from which the video and audio fields are recorded. Our study will add to an emerging field of research on the effects of simulated natural environments and provide the foundation for applied research on therapeutic applications for people with limited mobility or on bed rest, in assisted living facilities and hospitals, or in densely populated urban areas without access to nature.

Currently it remains unclear whether depression causes EF deficits, or whether EF deficits play an active role in the course of depression. The present study assessed whether executive function deficits predict increases in depressive symptoms over time prospectively, and whether rumination accounts for the relationship between EF deficits and depressive symptoms. Main conclusion: Self-reported EF deficits, specifically working memory deficits, predicted increases in depressive symptoms over time. Furthermore, rumination fully mediated the relationship between EF deficits and depressive symptoms.

As more people move into urban environments, the negative consequences of reduced connection with nature are becoming more apparent. One promising way to reverse this trend is by reconnecting humans with the natural world. Natural environments have been shown to exert beneficial influences on mental health; however, to effectively develop therapeutic interventions, there is a strong need to understand the mechanisms of action by which natural environments support positive mental health outcomes. This thesis investigated potential mechanisms of action for therapeutic nature exposure as well as the preliminary efficacy of nature exposure therapy in virtual reality. Research subjects completed a survey measure assessing previous visits to nature and self-reported mental health symptoms. They subsequently completed an in situ experimental session in which they received one of three treatments (real nature, virtual nature or no nature) and then completed a laboratory stress task. Levels of mindfulness during the stressor and changes in self-reported levels of state positive and negative affect before and after the stressor were assessed. Results showed nature visitation indirectly correlated with psychopathology and emotional responses to nature. Additionally, mindfulness covaried with nature treatment type (real nature or virtual nature) for positive affect. These results elucidate the relationship between nature and mental health and demonstrate the potential for virtual restorative environments to be used in the treatment of mental health disorders.
