Complexity has been always a part of an individual's life under different guises. However, it has always been hard to provide a clear definition of what complexity really is. For instance, in the field of science, complexity has been defined in terms of systems [vol. 284, Issue 5411, pp. 1-212]. A system can be deemed as complex when multiple interactions occur among different components or when the system evolves over time, where a recognizable structure is still present but varies in different ways in response to small perturbations or by being sensitive to initial conditions. This definition, as well as the concept of a system, can also be applied to human experience (e.g., Cipresso, 2010), whose unfolding takes place through the interactions of specific cognitive, perceptual, and emotional components bringing forth peculiar phenomena, which we labeled as “complex experiences.”

Research shows that reduced exposure to natural contexts is associated with an increase in psychophysical disorders. Recent evidence suggests that even a brief experience in natural scenarios can positively affect people's health and well-being. However, natural contexts are not always easily accessible. This study investigates the effects of natural and indoor virtual environments (VREs) on psychophysiological and cognitive responses. Following a within-subject design, 34 healthy participants were exposed to two VREs (i.e., a forest and a living room) in a counterbalanced order through a head-mounted display (Oculus Rift). Participants were asked to explore the scenarios and execute a modified version of the Paced Auditory Serial Addition Test. Physiological parameters (heart rate, skin conductance level [SCL], and respiration rate) were recorded during the whole session. After the exposure to VREs, participants filled a set of visual analog scales to rate their subjective experience of presence, relaxation, and stress. Participants reported a higher perceived sense of relaxation in the virtual forest. Moreover, their SCLs were significantly higher in this environment, showing that the forest elicited higher physiological arousal than the living room. Furthermore, their SCLs were significantly higher during the attentional task in the virtual living room. The results suggest that a natural virtual environment can make people feel more relaxed and physiologically engaged than an indoor scenario. The latter instead can be linked to a performing venue, as reported for real contexts. However, these changes were not related to modulations of attentional performance.

Cognitive frailty is defined as a clinical condition characterized by both physical frailty and cognitive impairment, without reaching the criteria for dementia. The major goal of rehabilitation intervention is to assist patients in performing ordinary personal duties without the assistance of another person, or at the very least to remove the need for additional support, using adaptive approaches and facilities. In this regard, home-based rehabilitation allows patients to continue an intervention begun in a hospital setting while also ensuring support and assistance when access to healthcare systems is limited, such as during the present pandemic situation. We thus present Brain m-App, a tablet-based application designed for home-based cognitive rehabilitation of frail subjects, addressing spatial memory, attention, and executive functions. This app exploits the potential of 360° videos which are well-suited to home-based rehabilitation. The Brain m-app is made up of 10 days of activities that include a variety of exercises. The activities were chosen based on those patients used to do during their clinical practice in the hospital with the aim to improve their independence and autonomy in daily tasks. The preliminary usability test, which was conducted on five older people, revealed a sufficient level of usability, however, the sample size was modest. Results from the clinical study with 10 patients, revealed that Brain m-App improved especially executive functions and memory performances.

Since Mark Zuckerberg's announcement about the development of new three-dimensional virtual worlds for social communication, a great debate has been raised about the promise of such a technology. The metaverse, a term formed by combining meta and universe, could open a new era in mental health, mainly in psychological disorders, where the creation of a full-body illusion via digital avatar could promote healthcare and personal well-being. Patients affected by body dysmorphism symptoms (i.e., eating disorders), social deficits (i.e. autism) could greatly benefit from this kind of technology. However, it is not clear which advantage the metaverse would have in treating psychological disorders with respect to the well-known and effective virtual reality (VR) exposure therapy. Indeed, in the last twenty years, a plethora of studies have demonstrated the effectiveness of VR technology in reducing symptoms of pain, anxiety, stress, as well as, in improving cognitive and social skills. We hypothesize that the metaverse will offer more opportunities, such as a more complex, virtual realm where sensory inputs, and recurrent feedback, mediated by a “federation” of multiple technologies - e.g., artificial intelligence, tangible interfaces, Internet of Things and blockchain, can be reinterpreted for facilitating a new kind of communication overcoming self-body representation. However, nowadays a clear starting point does not exist. For this reason, it is worth defining a theoretical framework for applying this new kind of technology in a social neuroscience context for developing accurate solutions to mental health in the future.

Why and How Empathy Matters in Aesthetic Experiences

The concept of transformative experience (TE) has been widely explored by several disciplines from philosophy to neurobiology, and in different domains, from the spiritual to the educational one. This attitude has engendered heterogeneous models to explain this phenomenon. However, a consistent and clear understanding of this construct remains elusive. The aim of this work is to provide an initial comprehensive interdisciplinary, cross-domain, up-to-date, and integrated overview on the concept of TEs. Firstly, all the models and theories on TEs were reviewed to extract and analyze TEs’ main components emerging from different disciplines. Then, this preliminary analysis was integrated with an in-depth examination of redundancies and particularities across domains and disciplines, to provide an integrated theoretical framework of TEs and a preliminary interdisciplinary operational definition of TEs. This examination, in turn, can help organize current research and theories, thus providing suggestions for operationalizing TEs as well as encouraging new interdisciplinary research endeavors.

The emotion of awe, arising when the human being confronts himself with something vast, able to overwhelm current mental structures and to turn into a potentially transformative experience, has been recently introduced into the learning domain as a driver of knowledge-seeking behavior as well as an authentic trigger of interest towards science. However, to date, an awe-inspiring training for workers into the domain of science – specifically of STEM or STEAM – has not been designed and tested yet. In this study, we implemented recent scientific evidence concerning how to elicit intense instances of awe into an awe-inspiring training delivered through a social virtual reality (VR) platform-AltspaceVR. High-school teachers attended this novel awe-inducing training consisting of an autobiographical recall of awe as well as the exposure to awe-inspiring virtual environments (VREs). Their level of awe, presence, and affect were measured before and at the end of the training. Moreover, at the end of the experience, participants were involved in a focus group on the overall experience. Participants reported a profound sense of awe along with other related emotions, as well as a continuous sense of presence in the VRE. In conclusion, this training could pave the way for a multitude of applications, enhancing the individual involvement towards science and technology at any age.

Call for Special Issue Papers: Virtual Emotions: Understanding Affective Experiences in the Metaverse

In a society where advances and innovations occur on a daily basis, outreach and meaningful engagement with the general public become more challenging. The amount of information produced and repackaged surpasses existing systems in place to ensure truthful and factual engagement with the public, especially with complex matters regarding health science. This perspective paper discusses the value of contextualization and optimization for creating transparent and engaging content. We reflect on the innovative Transformative Storytelling Technique as a new category creating hybrid content to guide the experience of audiences, starting with the case of informal caregivers helping individuals living with neurological conditions. Moreover, we share our perspective on the important considerations for current and future development of highly targeted content using this technique. We include reflexions around the risks and ethical principles needed in the utilization and dissemination of “guided” content for the general public.

Transformation can be deemed as a process composed of specific emotional (e.g., awe) and cognitive components (worldview and mental schema) interacting together to trigger impactful experiences of transformation (TE). Several theories posited that one trigger of transformation can be something able to violate people’s current worldview. In Italy, the lockdown – requested by the Government to limit the consequences of pandemic-represented an unprecedented experience for Italian citizens. Although COVID-19 home confinement significantly impacted psychosocial wellbeing and encouraged the adoption of new communication technologies to overcome lockdown loneliness, no difference emerged in relation to lockdown intensity. However, the potential transformative impact of this event has not been tested yet. In this study, we measured fluctuations of nine healthy Italian people’s cognitive worldview and personality traits, as well as their disposition to live the complex emotion of awe in three timeframes (i.e., at the beginning of Italian Lockdown period, at the end, and one month after the end of the lockdown). No significant changes emerged from data analyses, thus suggesting that, despite the potential impact of this worldwide event, people’s stable worldview, personality factors, and complex emotion dispositions persisted, at least, immediately after the first lockdown period.

Mindfulness is one of the most popular psychotherapeutic techniques that help to promote good mental and physical health. Combining mindfulness with immersive virtual reality (VR) has been proven to be especially effective for a wide range of mood disorders for which traditional mindfulness has proven valuable. However, the vast majority of immersive VR-enhanced mindfulness applications have focused on clinical settings, with little evidence on healthy subjects. This narrative review evaluates the real effectiveness of state-of-the-art mindfulness interventions mediated by VR systems in influencing mood and physiological status in non-clinical populations. Only studies with an RCT study design were considered. We conclude that most studies were characterized by one single meditation experience, which seemed sufficient to induce a significant reduction in negative mood states (anxiety, anger, depression, tension) combined with increased mindfulness skills. However, physiological correlates of mindfulness practices have scarcely been investigated. The application of VR-enhanced mindfulness-based interventions in non-clinical populations is in its infancy since most studies have several limitations, such as the poor employment of the RCT study design, the lack of physiological measurements (i.e., heart rate variability), as well as the high heterogeneity in demographical data, technological devices, and VR procedures. We thus concluded that before applying mindfulness interventions mediated by VR in clinical populations, more robust and reliable methodological procedures need to be defined.
