The training of attentional capacities is an important part of many rehabilitative efforts, for example, in the treatment of stroke. The Helix-Arena is an innovative virtual reality (VR) training device, which enables multimodal training in a 360-degree virtual environment. A pursuit training was developed for the Helix-Arena. In this study, we evaluate the effectiveness of the pursuit training in the Helix-Arena compared to a control group [CG, training on a personal computer (PC)] in 34 healthy participants. The experimental group (EG, N = 19) participated in four training sessions in the Helix-Arena over a period of 2 weeks. The control group (N = 15) completed similar training sessions in a non-VR environment on a PC. During each training session, changes in attention (Test of Attentional Performance battery, TAP) and general mood (Positive and Negative Affect Schedule, PANAS) were assessed pre- and post-training. A significantly higher pre-to-post improvement was observed in the EG for the TAP subtest attention shift in the subcategory invalid instructor ( p = 0.04) than that in the CG. In addition, we found a higher positive affect after the training in the EG but not in the CG (p < 0.01). These results suggest advantages of the VR environment for attentional and affective processes. The VR training can thus improve not only cognitive abilities but also training motivation. In a next step, the training can be used with patients in a rehabilitation context, but it is also suitable for educational and gaming contexts.
With all my senses
restorative environments through holistic sensory impressions
(2017) Sona, Brid; Steidle, Anna
Growing awareness of psychological health problems is resulting in various research areas exploring new approaches to fostering personal resources. Restorative Environments Theory (RET) has shown that mundane natural environments support personal resources. Although other restorative environments may exist besides mundane natural environments, their systematic examination is still lacking. In the real world, users experience environments through all their senses. However, most of the recovery research focuses on investigation of single sensory impressions. Thus, concrete insights into how various ambient qualities of an environment may affect users’ perception are still needed. The main aim of this doctoral thesis is to enhance the existing theoretical framework of restorative environments and to give an overview of research while pointing out where more research is needed. Further, the thesis includes identification of restorative environments and their specific ambient qualities. Based on the explored environments, the present research will point out psychological pathways to obtain recommendations for the design of restorative environments. The first research project was an explorative study to identify restorative places and their ambient qualities. In accordance with restoration research, participants described natural outdoor environments which they sought for recovery. In addition, they described indoor environments. Depending on the type of depletion and the environmental setting, specific environments and ambient qualities were evaluated as more important for the restorative potential of the place than others. This explorative research supports theory building and enables creation of restorative environments through holistic sensory impressions. Finally, strengths, limitations and practical implications for designing and improving restorative environments are discussed. The second research project takes up the findings of the first project by simulating sensory-enriched break environments. Based on the impact of holistic sensory impressions, this project is one of the first to reveal the impact of the recovery process of simulated environments on personal resources through congruent sensory impressions. Analyses confirmed that sensory-enriched environments were perceived as more pleasant and more restorative than less enriched environments, which in turn facilitated the recovery of personal resources. The results point out the relevance of holistic sensory impressions to fostering recovery. Implications and limitations of sensory enrichment in break environments are discussed. To broaden generalizability, the third research project comprises three field experiments investigating recovery during break interventions which offered virtual restorative environments with differing degrees of immersion and different types of environments. Building on previous research (Grimshaw, 2014), the third project posited that a higher degree of immersion in the simulated environment increases perceived realism, which becomes apparent in higher positive perceptions and recovery outcomes. Moreover, environments with different degrees of stimulation were anticipated to evoke distinct successful recovery. Previous research had mainly focused on calming environments for recovery. Additionally, this project also tested whether stimulating environments promote recovery outcomes. Results mainly confirmed the proposed hypotheses. The relevance of immersion and the impact of different types of natural environments on recovery are discussed. Overall, the current research emphasizes the impact of holistic sensory impressions in enhancing positive perceptions of the environment and, consequently, various recovery outcomes. The conducted studies uncover the psychological pathway from the processes of sensory perception to environmental recovery perception, followed by recovery outcomes. Beside these theoretical insights, the current research delivers concrete recommendations for designing restorative (virtual) environments in the workplace.
